The Complete Guide to Seafood: From Ocean to Table

Written by on in Learn

There’s a rhythm to life near the ocean that you carry with you forever. Growing up in New England, I learned early that the sea wasn’t just something beautiful to look at—it was part of our livelihood, our culture, our dinner table. The fishing boats heading out before dawn, the gulls wheeling overhead at the docks, the smell of salt air mixed with diesel and brine—these weren’t just background details. They were the foundation of everything.

My first memories of seafood aren’t from a fancy restaurant. They’re from fish markets with giant tanks, where my father would talk to the fishmonger about what came in that morning. They’re from summer church clambakes, lobster shacks with picnic tables overlooking the lighthouse, and Friday night fish fries at the church hall. Seafood wasn’t exotic or intimidating. It was what we ate, how we celebrated, and how we connected to the place we called home.

But I also understand that for many people, seafood can feel like the most mysterious category in the kitchen. Fish counters can be overwhelming with their array of unfamiliar names and whole creatures staring back at you. The rules seem different—how do you know if it’s fresh? How long can you keep it? How do you cook something so delicate without ruining it? And then there are the bigger questions about sustainability, mercury levels, and whether we should be eating certain species at all.

This guide aims to demystify all of it. We’ll explore the incredible diversity of seafood—from the fish that built New England’s economy to the shellfish that mark our seasons, from techniques that have been used for centuries to modern sustainability practices. Whether you’re a confident cook looking to expand your seafood repertoire or someone who’s never bought a whole fish, there’s something here to help you understand this remarkable food source.

Seafood matters for so many reasons. It’s one of the healthiest protein sources we have, rich in omega-3 fatty acids and lean protein. It connects us to specific places and cultures in ways that few other foods can—you can taste the ocean, the region, even the season in a piece of truly fresh fish. And when sourced responsibly, seafood can be one of the most sustainable proteins available, with lower environmental impact than many land-based options.

The ocean has fed humans for as long as we’ve existed. The techniques, traditions, and knowledge passed down through fishing communities represent thousands of years of wisdom about tides, seasons, migrations, and preparation methods. Every coastal culture has developed its own relationship with the sea, its own ways of honoring and preparing what the water provides.

In this guide, we’ll start close to home—with New England’s remarkable seafood history that shaped not just our region but global trade patterns. Then we’ll explore the vast world of fish, shellfish, and other sea creatures, learning to identify, select, store, and cook each type. We’ll travel through global seafood traditions, understanding how different cultures have perfected their relationships with the ocean. And we’ll tackle the modern questions about sustainability and responsibility that any thoughtful seafood lover needs to consider.

My hope is that this guide helps you feel more confident at the fish counter, more adventurous in trying new species, and more connected to the incredible resource that is our ocean. Every time you cook seafood well—whether it’s a simple pan-seared fillet or a celebratory lobster dinner—you’re participating in one of humanity’s oldest food traditions.

Let’s dive in.

New England Seafood History: How the Ocean Built a Region

To understand seafood in New England is to understand how this region came to be. The ocean wasn’t just a geographic feature—it was the economy, the highway, the pantry, and the reason people came here in the first place. The story of New England seafood is the story of indigenous wisdom, colonial ambition, immigrant ingenuity, and ongoing adaptation to an ecosystem we’re still learning to respect.

Indigenous Fishing Traditions: The First Stewards

Long before European ships appeared on the horizon, the Indigenous peoples of coastal New England had developed sophisticated relationships with the ocean and its resources. The Wampanoag, Abenaki, Penobscot, and other coastal nations weren’t just fishing—they were managing marine resources with an understanding of sustainability that we’re only now beginning to relearn.

Archaeological evidence tells a vivid story. Shell middens—massive piles of discarded oyster, clam, and mussel shells—dot the New England coast, some dating back thousands of years. These aren’t just garbage heaps. They’re records of seasonal harvesting patterns, showing that Indigenous peoples moved with the seasons, fishing for different species as they became abundant, never depleting any single resource.

They fished for alewives and shad during spring spawning runs. They gathered shellfish during low tides. They caught eels in intricate weirs built in tidal estuaries. They harpooned seals and porpoises. And they taught the arriving colonists which fish were worth catching, where to find them, and how to use them to fertilize corn fields—a practice that would become crucial to colonial survival.

Tisquantum (known as Squanto) famously taught the Pilgrims to bury fish with their corn seeds, but this represented just a fragment of a deep knowledge system about marine ecosystems. Indigenous peoples understood fish migrations, knew which shellfish beds could be harvested without depletion, and had processing methods—like smoking and drying—that preserved seafood through winter months.

This wasn’t random foraging. It was careful stewardship of a resource that fed communities year after year, generation after generation. The concept of taking only what you need, rotating harvest areas, and respecting spawning seasons—these weren’t modern conservation ideas. They were ancient wisdom that sustained peoples for millennia.

Colonial Era: The Sacred Cod and the Trade That Built an Economy

When European fishermen began exploring the waters off New England in the late 1400s and early 1500s, they found something extraordinary: cod. Not just a few cod, but waters so thick with fish that, according to multiple historical accounts, you could practically walk across their backs. The Grand Banks and Georges Bank teemed with Atlantic cod in numbers that seemed inexhaustible.

This abundance changed everything. Cod became so central to Massachusetts that a carved wooden “Sacred Cod” has hung in the State House since 1784, a tribute to the fish that built the colony’s wealth. This wasn’t just symbolism—it was honest recognition that without cod, there might not have been a Massachusetts at all.

Here’s how it worked: Cod could be salted and dried, creating a protein source that would last for months without refrigeration. This made it perfect for long sea voyages and for trade. New England fishermen would catch cod, salt it on board or bring it to shore for processing, and then ship it around the world.

The triangular trade route depended on it. Salt cod from New England went to the Caribbean to feed enslaved people on sugar plantations. Molasses from those plantations came back to New England to be made into rum. The rum went to Africa to trade for enslaved people, who were then taken to the Caribbean. It was a horrific system, and dried cod was one of its essential economic components.

The best grade of cod—thick, white, perfectly salted—went to Catholic Europe, especially Spain, Portugal, and Italy, where meatless Fridays and Lent created huge demand. Lower grades went to the Caribbean. The fishing fleet grew massive. Entire towns existed to support it. Gloucester, New Bedford, and countless smaller ports sent hundreds of schooners to the Grand Banks each season.

The work was brutal. Fishermen spent weeks at sea in small dories, hand-lining for cod in all weather. Ships were lost. Men died. But the money was good enough that fishing attracted waves of immigrants, especially from Portugal and Italy, who brought their own seafood traditions and became integral to New England’s fishing culture.

By the 1800s, Gloucester alone had over 400 fishing schooners. The waterfront was a forest of masts. Fish houses lined the shore, where women worked splitting, salting, and packing cod. The smell of drying fish hung over entire towns. It wasn’t picturesque. It was industrial-scale fish processing, and it made people wealthy.

What nobody understood then was that the resource wasn’t infinite. It would take until the late 20th century for that lesson to become devastatingly clear.

The Rise of the Lobster Industry: From Poverty to Luxury

There’s a persistent story that lobster was once so plentiful that it washed up on beaches in piles, and that servants had clauses in their contracts limiting how often they could be fed lobster. While some of this is exaggerated, there’s truth to the core: lobster was not always luxury food.

In colonial times and well into the 1800s, lobster was considered suitable for prisoners, servants, and the poor. It was fertilizer. It was bait for cod fishing. Eating lobster regularly was seen as a mark of poverty, not sophistication.

So what changed? Several things. First, railroads made it possible to ship live lobsters to cities, where they became exotic rather than common. Second, as beef prices rose in the mid-1800s, lobster became comparatively affordable. Third, canning technology allowed lobster meat to be preserved and shipped even further.

By the early 1900s, lobster had completed its transformation. It appeared on fancy restaurant menus. It became a celebration food. Coastal Maine reinvented itself around lobster tourism, building pounds and shacks where visitors could eat lobster while watching boats come in.

The industry developed its own culture. Lobster boat licenses became hereditary, passed down through families. Territories were established and respected. Fishermen developed incredible knowledge of where lobsters lived, how they moved, when to set traps. The wooden lobster trap, built by hand in winter months, became iconic.

Maine’s lobster fishery is now one of the most carefully managed in the world. Size limits, trap limits, breeding female protections, and v-notching (marking breeding females so they must be released if caught again) have kept the population relatively stable even as fishing pressure increased. It’s not perfect, but it represents generations of fishermen learning to sustain the resource that sustains them.

The lobster pound—where live lobsters are kept in floating crates until they’re sold—became a New England institution. So did the lobster roll, that perfect combination of sweet lobster meat, minimal mayo, and a butter-griddled bun. And the summer lobster bake, where lobsters steam on a bed of seaweed with corn and potatoes, became the quintessential New England gathering.

Today, Maine lobster is a $1 billion industry. The boats are fiberglass now instead of wood, and GPS has replaced local knowledge for finding good spots (though old-timers will tell you nothing replaces years of experience). But the basic pattern remains: setting traps, checking them daily, measuring each lobster, throwing back anything illegal, and working incredibly hard in all weather to make a living from the sea.

The Oyster Boom and Decline: Lessons in Overexploitation

Before there was lobster mania, there was oyster mania. And the story of New England’s oysters is a cautionary tale about what happens when we treat the ocean as an endless resource.

In the 1800s, oysters were everywhere along the New England coast. Wellfleet on Cape Cod was world-famous for its oysters. So was Providence, Rhode Island. Oyster beds stretched for miles in shallow bays and estuaries. Indigenous peoples had been harvesting them sustainably for thousands of years. But when commercial oystering began in earnest, sustainability went out the window.

The railroad changed everything. Suddenly, oysters harvested in Wellfleet could be on a New York dinner plate the next day. Demand exploded. Oyster saloons became ubiquitous in cities. Raw oysters, fried oysters, oyster stew—they were cheap protein and trendy food all at once.

New England oystermen couldn’t harvest fast enough to meet demand. Boats worked the beds constantly. There were no size limits, no seasonal closures, no catch limits. If you could sell it, you could take it. And everyone could sell them.

By the early 1900s, many of the great natural oyster beds were gone. Wellfleet’s wild oysters collapsed. Providence had to import seed oysters from Chesapeake Bay. What had seemed inexhaustible proved devastatingly finite.

Pollution made things worse. As coastal towns grew, sewage and industrial waste flowed into the same bays where oysters lived. Oysters are filter feeders—they clean water by filtering out particles. But that also means they concentrate any bacteria or contaminants in that water. Contaminated oyster beds had to be closed. Some never recovered.

But here’s where the story gets hopeful: New England is now in the midst of an oyster renaissance. Aquaculture—farming oysters from seed in clean waters—has brought oysters back. Wellfleet oysters are once again world-famous, but now they’re farm-raised in carefully managed areas. The same is true in the Damariscotta River in Maine, in Duxbury Bay, in dozens of locations along the coast.

Oyster farmers are innovators. They use methods like flip bags, floating cages, and bottom culture to raise oysters efficiently while keeping the ecosystem healthy. Unlike fish farming, oyster farming is actually beneficial to water quality—those oysters are filtering and cleaning the water as they grow.

And with aquaculture came terroir. Oysters from different bays taste different because they’re filtering different waters. A Wellfleet tastes different from a Duxbury, which tastes different from a Pemaquid. Oyster menus started reading like wine lists, with origin and tasting notes. What was once cheap abundance became artisanal appreciation.

The lesson? The ocean can recover if we give it a chance and manage it intelligently. But the old abundance—those miles-long beds of wild oysters—those are mostly gone. What we have now is different: smaller, managed, requiring human intervention. It’s better than nothing, but it’s a reminder that some things, once lost, don’t come back the same way.

The Portuguese Fishing Heritage: Innovation and Culture

Walk through the fishing ports of New Bedford or Gloucester, and you’ll see the Portuguese influence everywhere. In the surnames on boat sterns, in the restaurants serving grilled sardines and seafood stew, in the festivals celebrating Nossa Senhora do Bom Sucesso (Our Lady of Good Success), the patron saint of fishermen.

Portuguese immigrants, particularly from the Azores and Cape Verde, began arriving in New England in significant numbers in the mid-1800s. They came because they were already fishermen, and New England’s fishing fleet desperately needed skilled crews willing to do dangerous work.

They didn’t just fill positions—they transformed the industry. Portuguese fishermen brought techniques from the Grand Banks cod fishery and adapted them to New England waters. They were instrumental in developing the scallop fishery, creating the draggers and dredges that made large-scale scallop harvesting possible.

New Bedford became the scalloping capital of the world largely because of Portuguese innovation and labor. The boats were often Portuguese-owned, Portuguese-crewed, and Portuguese-captained. The knowledge of where scallops lived, how to drag efficiently, how to shuck and process them—much of this came from that community.

But it wasn’t just technique. Portuguese fishermen brought their food culture. They brought bacalhau (salt cod) recipes that had sustained Portuguese sailors for centuries. They brought the tradition of grilling fresh sardines and mackerel, fish that Americans often overlooked. They brought the practice of making fish stew with whatever the day’s catch provided.

These traditions soaked into New England cuisine. That’s why you can find excellent Portuguese-style grilled fish in Massachusetts fishing towns. It’s why chouriço shows up in clam boils alongside corn and potatoes. It’s why certain neighborhoods smell like salt cod soaking on Fridays, being prepared for weekend bacalhau dishes.

The community also brought a deep cultural connection to the sea. Blessing of the fleet ceremonies, where priests bless fishing boats at the start of the season, came from Portuguese Catholic tradition. The memorials to lost fishermen, listing hundreds of names—those honor Portuguese fishermen who never came home from the Grand Banks or Georges Bank.

Today, that heritage continues. Many of New Bedford’s fishing boats still carry Portuguese names. The city’s fishing infrastructure—the processing plants, the auction houses, the marine supply stores—much of it was built by Portuguese immigrants and their descendants. The knowledge of how to fish successfully in these waters has been passed down through families, in Portuguese and English both.

It’s a reminder that food culture isn’t static. It’s created by the people who do the work, who bring their own traditions and innovations, who adapt to new waters while honoring old ways.

Modern New England Fisheries: Regulation, Collapse, and Recovery

The confidence of the fishing industry in the 1960s and 70s is hard to imagine now. Boats got bigger. Technology advanced. Sonar found fish schools with precision. Massive factory trawlers from Europe and Asia appeared on the Grand Banks, processing thousands of tons of fish at sea. Everyone believed the ocean was so vast that we couldn’t possibly deplete it.

They were wrong.

By the 1990s, Atlantic cod stocks had collapsed. The fish that had seemed inexhaustible was suddenly commercially extinct in many areas. The Grand Banks, which had produced cod for 500 years, were fished out. Canada closed its cod fishery in 1992. Thousands of fishermen lost their livelihoods overnight.

New England followed with severe restrictions. Huge areas were closed to fishing. Quotas became tiny. Boats that had fished for generations were tied up at the dock, worthless. Fishing families lost everything. Entire communities built around groundfishing—cod, haddock, flounder—watched their economy collapse.

It was devastating, but it was necessary. The alternative was total extinction of these species. And slowly, under strict management, some populations began to recover. Haddock came back faster than cod. Some flounder species stabilized. It’s not the abundance of the past, and it may never be, but the ocean proved it could heal if given the chance.

The recovery required complete restructuring of how fishing is managed. Individual quotas replaced the race-to-fish. Observers went on boats to verify catches. Closed areas protected spawning grounds. Mesh size regulations let juvenile fish escape. It wasn’t popular—fishermen resented the restrictions, the monitoring, the loss of autonomy. But gradually, even skeptics had to admit that without these measures, there would be no fish left to catch.

Today’s New England fishing fleet is a fraction of its former size. Gloucester’s waterfront, once packed with fishing boats, now has more whale-watching vessels and recreational boats than working draggers. The fish auction at New Bedford is still one of the most valuable in the country, but it’s scallops and other species keeping it going, not the groundfish that built the port.

Meanwhile, aquaculture has emerged as a growing part of the seafood economy. Oyster farming has created new jobs in towns where wild fisheries failed. Rope-cultured mussels hang in the current, growing plump while filtering water. Some companies are experimenting with finfish aquaculture, though this remains controversial due to pollution concerns.

The future of New England seafood will look different from its past. It will be smaller, more regulated, more conscious of limits. It will include more farmed seafood alongside wild-caught. It will require accepting that the ocean isn’t infinite, that species need protection, that sustainability isn’t just an ideal but a necessity.

But as long as boats still head out from Gloucester and Portland, as long as lobster traps get hauled in the early morning, as long as oyster farmers check their cages and fishmongers know what came in that day—the tradition continues. It’s adapted, restricted, humbled by hard lessons, but it persists. And there’s something valuable in that persistence, in the stubborn belief that humans and the ocean can find a way to coexist.

The World of Fish: Understanding What Swims in Our Seas

Fish are remarkably diverse, and understanding the basic categories helps make sense of what you’re seeing at the market and how to cook it. The differences aren’t arbitrary—they reflect where fish live, how they move, what they eat, and ultimately how they taste and what cooking methods suit them best.

Understanding Fish Categories

Fish fall into several overlapping categories that help predict their characteristics. A fish can be white and flat and saltwater all at once, and each of those categories tells you something useful.

White Fish vs. Oily Fish: This is about fat content and where that fat is distributed. White fish (also called lean fish) store fat in their livers rather than throughout their flesh. Think cod, halibut, sole, snapper. The flesh is pale, mild, and flaky when cooked. These fish tend to be more delicate and can dry out easily if overcooked.

Oily fish distribute fat throughout their flesh, giving them darker meat and richer flavor. Salmon, tuna, mackerel, sardines, bluefish—these have more omega-3 fatty acids, stronger flavor, and more forgiving cooking properties since that fat keeps them moist. They can handle higher heat and longer cooking than white fish.

Nutritionally, oily fish are particularly valuable for those omega-3s, which is why they’re so often recommended for heart health. But they also have stronger flavors that some people find challenging. White fish is typically milder and more accessible for people who say they “don’t like fish.”

Freshwater vs. Saltwater: Where a fish lives affects its flavor and texture. Saltwater fish tend to have firmer flesh and cleaner flavor. Freshwater fish can sometimes have a muddy or earthy taste, especially if they’re bottom feeders from ponds or slow-moving water. Trout from cold, moving streams tastes clean and delicate. Catfish from warm ponds can taste muddy unless carefully raised.

Saltwater fish also generally have higher mineral content from the sea. Some people claim they can taste the ocean in truly fresh saltwater fish, and there’s truth to that—the salt, the brine, the essence of where they lived.

Flat Fish vs. Round Fish: This anatomical difference affects how the fish is filleted and what yield you’ll get. Round fish (salmon, cod, bass) swim horizontally and have an eye on each side of their head. They produce two fillets, one from each side.

Flat fish (flounder, sole, halibut) lie on one side on the ocean floor and have both eyes on the top side. They produce four smaller fillets—two from the top, two from the bottom. The meat tends to be very delicate and sweet, perfect for gentle cooking methods like poaching or pan-searing with butter.

Texture Categories: Some fish are flaky, falling into tender chunks when cooked—cod, haddock, snapper. Some are meaty and steak-like, holding together firmly—tuna, swordfish, mahi-mahi. Some are delicate and almost creamy—sole, flounder, black bass. And some are dense and firm—monkfish, grouper.

Knowing texture helps you choose cooking methods. Flaky fish works beautifully in tacos or fish and chips. Meaty fish can go on the grill or get cut into chunks for kebabs. Delicate fish needs gentle handling and quick cooking. Dense fish can handle braising or stewing.

Cod: This is the fish that built New England, and it remains a kitchen workhorse. Atlantic cod has mild, slightly sweet flavor and large, tender flakes. It’s incredibly versatile—perfect for fish and chips, beautiful pan-seared with brown butter (as in the recipe on this site), excellent in chowder, lovely baked or broiled. Pacific cod is similar but slightly firmer.

The challenge with cod is that it’s still recovering from overfishing, so wild Atlantic cod can be expensive and hard to find sustainably. Pacific cod from Alaska is generally a better sustainable choice. Some markets sell Icelandic or Norwegian cod, which come from better-managed fisheries.

Cod’s mild flavor makes it perfect for people who are tentative about fish. It doesn’t taste “fishy.” It takes on whatever flavors you pair with it—lemon and capers, curry spices, tomato sauce, Asian aromatics—while contributing its own delicate sweetness and satisfying texture.

Salmon: Probably the most popular fish in America, salmon comes in many varieties with distinct characteristics. Atlantic salmon is almost always farmed (wild Atlantic salmon is critically endangered). It has high fat content, bright orange color, and rich flavor. The farming can be problematic environmentally, though some operations are better than others.

Wild Pacific salmon—King/Chinook, Sockeye, Coho, Pink, and Chum—come from Alaska and the Pacific Northwest. King is the richest and most prized, with deep red flesh and high fat content. Sockeye is deep red with robust flavor. Coho is lighter and more delicate. Pink and Chum are the most affordable but can be dry if overcooked.

Indigenous peoples of the Pacific Northwest have harvested salmon for thousands of years, developing sophisticated methods of catching, preserving, and celebrating these fish. The annual salmon runs were—and still are—central to cultural and spiritual life. Smoked salmon, salmon jerky, and salmon preserved in cedar are all traditional preparations worth knowing about.

Salmon is forgiving to cook because that fat keeps it moist. It’s excellent grilled, roasted, poached, or even raw in sushi. The challenge is not overcooking it—salmon is best when still slightly translucent in the center, which many people find unsettling if they’re used to cooking it through.

Tuna: Fresh tuna is a completely different experience from canned. It’s meaty, dense, almost steak-like. Bluefin tuna is the most prized (and most overfished—avoid unless you can verify sustainable sources). Yellowfin (ahi) is common in restaurants and markets. Albacore is the “white tuna” often canned. Skipjack is usually what’s in inexpensive canned tuna.

Tuna should be served rare to medium-rare unless you’re deliberately cooking it through for something like tuna salad. When overcooked, it becomes dry and mealy. When properly cooked, it’s tender, rich, and satisfying.

In Japan, tuna is revered. The fatty belly (toro) commands extraordinary prices. Different parts of the tuna have different fat content and are used for specific preparations. Mediterranean cultures love tuna too—Italian tonnato sauce, Spanish atún, French tuna niçoise.

Sustainability is crucial with tuna. Some populations are severely overfished. Look for pole-and-line caught, troll-caught, or other selective methods. Avoid any tuna caught with FADs (fish aggregating devices) which have high bycatch.

Halibut: This is premium white fish—firm, meaty, and sweet with large flakes. Pacific halibut from Alaska is well-managed and sustainable. Atlantic halibut is overfished in many areas. California halibut is actually a different species (a flounder) but marketed as halibut.

Halibut is wonderful grilled, roasted, or pan-seared. It’s firm enough to make kebabs, substantial enough to satisfy people who think fish isn’t filling. It’s mild enough to please fish skeptics while having enough character to interest seafood lovers. The catch is the price—halibut is expensive, so it’s worth cooking it with care.

Haddock: Similar to cod but slightly firmer with a bit more flavor. Haddock is traditional in British fish and chips and in finnan haddie (smoked haddock), a New England breakfast dish that deserves more attention. It has all the versatility of cod with a little more personality.

Haddock recovered faster than cod from overfishing, so it’s often a more sustainable choice. It’s also usually less expensive than cod while being essentially interchangeable in recipes.

Flounder and Sole: These flat fish are delicate, sweet, and tender. Dover sole (actually a flounder) is the gold standard in European cooking—delicate, refined, perfect for simple preparations with butter and lemon. Other sole and flounder varieties can range from excellent to mediocre depending on species and freshness.

The thin fillets cook very quickly. They’re perfect for pan-searing in butter, for classic sole meunière, or for delicate poaching. Because they’re so lean, they need gentle handling and shouldn’t be overcooked. They’re elegant rather than robust—the kind of fish that makes you pay attention while you eat.

Trout: Rainbow trout is usually farmed and widely available. It has delicate, sweet flesh and cooks quickly. Whole trout are perfect for pan-frying or grilling. Brook trout and brown trout are usually wild-caught and have more complex flavor. Arctic char, a close relative, is increasingly farmed and has beautiful pink flesh similar to salmon but more delicate.

Trout has lovely tradition in European cooking—trout with almonds, trout grenobloise, smoked trout. It’s accessible, affordable, and a great entry point for people learning to cook whole fish since it’s small and manageable.

Bass: Striped bass (also called rockfish) is a New England favorite with firm, white flesh and clean flavor. It’s carefully regulated because populations crashed from overfishing but have recovered under strict management. Chilean sea bass (actually Patagonian toothfish) became wildly popular in the 1990s for its rich, buttery flesh, leading to overfishing problems.

Farmed striped bass and hybrid striped bass (striped bass crossed with white bass) are more readily available and avoid the sustainability issues of wild-caught. European sea bass (branzino) is commonly farmed and shows up on restaurant menus—mild, flaky, usually served whole.

Mackerel: This oily fish is underappreciated in the U.S. but beloved in Spain, Portugal, and Japan. Atlantic mackerel (Boston mackerel) is small, sustainable, and affordable. Spanish mackerel is larger. King mackerel can accumulate more mercury due to size.

Mackerel has assertive flavor that some people love and others find too strong. It’s excellent grilled, broiled, or smoked. In Spanish cuisine, mackerel is marinated and grilled whole. Portuguese cooks love grilled sardines and mackerel with just salt, olive oil, and lemon. Japanese preparations include saba (salted and grilled mackerel) and shime saba (vinegar-cured mackerel for sushi).

Because mackerel is oily, it doesn’t keep as long as lean fish. Buy it very fresh and cook it soon. The reward is rich, omega-3 packed fish at a fraction of the cost of salmon or tuna.

Sardines and Anchovies: Fresh sardines are completely different from canned. They’re small, oily fish usually grilled or fried whole. In Portugal and Spain, grilled sardines are street food, festival food, everyday food. They’re affordable, sustainable, and nutritious.

Anchovies, when fresh, are mild and delicate—nothing like the assertive preserved anchovies Americans know from pizza. In Italy, fresh anchovies are marinated raw (alici marinate), fried, or grilled. Preserved anchovies—salt-packed or oil-packed—are a different ingredient entirely, used for their intense umami rather than as a fish to eat whole.

Both sardines and anchovies are low on the food chain, which means they’re more sustainable than predator fish and accumulate less mercury. They’re also affordable and widely available. Learning to appreciate them opens up a whole category of cooking.

Swordfish: This meaty fish has firm, dense flesh perfect for grilling. It’s popular in Mediterranean cooking—Sicilian pesce spada, Greek xiphias—and in New England sport fishing. Swordfish steaks are easy to handle, hard to overcook (though possible), and satisfying for people who want something substantial.

The concerns are mercury (swordfish is a large predator that accumulates mercury) and sustainability (some populations are better managed than others). It’s a special occasion fish rather than an everyday choice.

Fish Anatomy and Cuts

Understanding how fish is butchered helps you know what you’re buying and how to use it.

Whole Fish: The entire fish, usually gutted and scaled but with head and tail intact. This gives you the most value per pound and the best flavor (bones add richness during cooking). It’s also the best indicator of freshness—eyes, gills, and skin tell you immediately how fresh the fish is.

Whole fish can be roasted, grilled, steamed, or fried. In many cultures, serving whole fish is a sign of respect and celebration. Learning to eat whole fish—navigating bones, finding the sweet meat along the spine—is a skill worth developing.

Fillets: The sides of the fish removed from the bone. Round fish give two fillets. Flat fish give four thinner fillets. Skin-on fillets are more flavorful and the skin helps hold the delicate flesh together during cooking. Skinless fillets are easier to eat but more prone to falling apart.

Pin bones are the small bones that run along the center of the fillet. They should be removed before cooking, though some fish markets don’t bother. Running your finger along the fillet will help you feel them, and you can pull them out with tweezers or clean pliers.

Steaks: Cross-sections of large round fish like salmon, tuna, or swordfish. They include a section of backbone, which adds flavor during cooking. Steaks are easier to handle than fillets since the bone helps them hold together. They’re ideal for grilling.

Loins: The premium center section of large fish, boneless and uniform. Tuna loins are common. They’re expensive but completely usable with no waste.

Special Cuts: Fish collars (the area behind the gills) are prized in Japanese cooking for their rich, fatty meat. Fish cheeks are tender and sweet. These cuts are usually inexpensive if you can find them because Americans generally don’t know to ask for them.

Shellfish: Bivalves

Bivalves—mollusks with two shells hinged together—are some of the most sustainable seafood you can eat. They filter water as they feed, actually cleaning their environment. They don’t require fishing vessels burning fuel to chase them around. And they offer some of the purest ocean flavor you’ll find.

Clams

New England’s relationship with clams goes back millennia. The indigenous peoples left shell middens marking centuries of clam harvests. Today, that tradition continues at clambakes, in chowder houses, and at raw bars along the coast.

Hard-shell Clams (Quahogs): Named by the Narragansett people, quahogs are sold by size. Littlenecks are the smallest, sweet and tender, perfect raw or steamed. Cherrystones are medium, good raw or cooked. Quahogs (the name used for the largest size) are too tough to eat whole but perfect for chowder or stuffies (Rhode Island stuffed clams).

Hard-shell clams live in sand or mud. You can harvest them by raking in shallow water at low tide, though most commercially sold clams are farm-raised now. They’ll keep for days refrigerated, making them more forgiving than many types of seafood.

When buying hard-shell clams, they should be tightly closed or close when tapped. Any clam that won’t close is dead and shouldn’t be eaten. They should smell like clean ocean, nothing sour or off.

Soft-shell Clams (Steamers): Despite the name, they do have shells—just thinner, more delicate shells than quahogs. Steamers are a New England summer tradition, typically served in a bucket with melted butter and broth for dunking.

The clam extends a long neck (siphon) that can’t fully retract into the shell. You peel the dark skin off the neck, dunk the clam in broth to rinse off any sand, dip it in butter, and eat it. It’s messy, casual, and wonderful.

Steamers tend to be sandier than hard-shell clams. When you get them home, let them purge in salt water (about 1/3 cup salt per gallon of cold water) for an hour or so. They’ll spit out sand, making them cleaner to eat.

Razor Clams: Named for their long, narrow shells that look like straight razors. They’re found on both coasts but are particularly prized in the Pacific Northwest. The meat is sweet and tender when properly prepared but can be tough if overcooked.

Razor clams are usually cleaned, cut into steaks, and quickly pan-fried. In Asian cooking, they’re often stir-fried with aromatics. They move fast and burrow deep, making them challenging to harvest—digging razor clams is a skill sport in some areas.

Manila Clams: Originally from Japan, these small clams were accidentally introduced to the Pacific Northwest and thrived. They’re sweet, tender, and excellent steamed. They’ve become a staple in Pacific Northwest seafood cooking.

Cooking Clams: Small clams are wonderful raw with lemon and mignonette. For cooking, steaming is classic—white wine, garlic, butter, and herbs until the clams open. Use them in pasta (linguine with clam sauce), in paella, in Asian-style preparations with black beans and ginger. The broth from steamed clams is liquid gold—save it for risotto or to fortify chowder.

Never eat a clam that doesn’t open during cooking. If it stays closed, it was dead before you cooked it. Also, a little bit of grit is normal—clams live in sand. But excessive sandiness means they weren’t purged properly.

Mussels

Mussels might be the most underappreciated bargain in seafood. They’re inexpensive, sustainable, easy to cook, and delicious. Yet many Americans overlook them in favor of more familiar shellfish.

Blue Mussels: The common mussel of the North Atlantic. Most commercially sold mussels are rope-cultured—grown on ropes suspended in the water. This keeps them clean (minimal sand or grit), plump, and sustainable. Wild mussels from rocky shores can be excellent but require more cleaning.

Blue mussels have sweet, tender meat and beautiful blue-black shells. They’re the mussels used in moules frites (Belgian mussels and fries), in Spanish seafood dishes, in Italian seafood pasta.

Mediterranean Mussels: Larger than blue mussels with a slightly different flavor. Common in Europe but less common in U.S. markets.

Green-lipped Mussels: From New Zealand, these large mussels have a distinctive green edge to their shells. They’re meaty and flavorful, often sold frozen.

Cleaning Mussels: Farmed mussels are pretty clean. Rinse them under cold water and pull off the beard (the stringy bit sticking out from the shell). Some mussels don’t have beards. Discard any with broken shells or any that won’t close when tapped.

Wild mussels need more attention. Scrub the shells with a brush under cold water to remove any dirt or barnacles. Then debeard them. Don’t debeard too far ahead of time—it kills the mussel, so do it right before cooking.

Cooking Mussels: Steaming is classic. In Belgium, mussels are steamed in white wine with celery and shallots, served with crispy fries and mayonnaise. In France, they might include cream and saffron. In Italy, they’re tossed with pasta, tomatoes, and white wine. In Spain, they go into paella.

Mussels cook fast—usually 5-7 minutes. They’re done when the shells open. Like clams, don’t eat any that stay closed. The broth from steamed mussels is intensely flavorful—don’t waste it. Serve the mussels in bowls with plenty of broth for soaking up with bread.

One note on timing: mussels don’t keep as well as hard-shell clams. Buy them the day you plan to cook them. Store them in the refrigerator covered with a damp towel (not in water—they’re alive and will drown in fresh water). They should smell like the ocean, nothing ammoniated or off.

Oysters

Oysters inspire passion. People become completists, seeking out oysters from different regions, comparing flavor profiles, developing strong preferences. It’s not pretension—oysters genuinely taste different depending on where they’re grown, creating something like terroir in wine.

Eastern Oysters: These grow from the Gulf of Mexico up to Canada. The same species (Crassostrea virginica), but the flavor varies dramatically by location. Wellfleet oysters from Cape Cod are briny and crisp. Blue Points from Long Island are mild and sweet. Malpeques from Prince Edward Island are balanced and minerally.

Water temperature, salinity, food availability—all these affect flavor. Oysters filter 20-50 gallons of water per day, so they literally taste like where they’re from. An oyster from cold Atlantic water tastes nothing like one from warm Gulf water.

Pacific Oysters: Smaller and frillier than Eastern oysters, Pacific oysters (Crassostrea gigas) were introduced from Japan and are now farmed extensively on the West Coast. Kumamoto oysters are a related species prized for their small size, deep cups, and sweet, buttery flavor.

Olympia Oysters: The tiny native oyster of the Pacific Northwest, nearly wiped out by overharvesting and pollution. Some farms are bringing them back. They’re intensely flavored and expensive—a special occasion oyster.

European Flat Oysters: Belons and other European flats have a metallic, mineral quality that people either love or hate. They’re less common in the U.S. but worth trying if you encounter them.

Shucking Oysters: You need an oyster knife—short, sturdy, with a dull blade and hand guard. Shucking takes practice. Hold the oyster in a towel with the hinge (pointed end) exposed. Work the knife tip into the hinge, wiggling it until you feel it pop. Slide the knife along the inside of the top shell to cut the adductor muscle. Remove the top shell, then slide the knife under the oyster to detach it from the bottom shell.

Keep the oyster level so you don’t lose the delicious liquor (liquid) in the shell. Serve on ice with lemon, mignonette (shallot vinegar sauce), or horseradish cocktail sauce. Traditionalists eat them with nothing but perhaps a squeeze of lemon.

Cooked Oysters: While raw is traditional, cooked oysters have their place. Oysters Rockefeller, created in New Orleans, combines oysters with a green sauce of herbs and bread crumbs under the broiler. Fried oysters are a Southern tradition. Grilled oysters with garlic butter are Gulf Coast favorites. Oyster stuffing is Thanksgiving tradition in many families.

When cooking oysters, remember they’re already cooked the moment their edges curl. Overcooking makes them rubbery.

Scallops

Scallops should be sweet, tender, and delicately briny. When they’re good, they’re extraordinary. But there are some important things to know about buying scallops.

Bay Scallops: Small, sweet, and tender. True bay scallops come from shallow bays and estuaries along the East Coast. They’re seasonal (fall and winter) and expensive. Calico scallops from the South are sometimes sold as bay scallops but aren’t the same—they’re smaller and less sweet.

Bay scallops are perfect quickly sautéed in butter or added to pasta. They cook in 1-2 minutes. Overcooking makes them rubbery.

Sea Scallops: Larger scallops from deeper water. Most commercially sold scallops are sea scallops. They can be huge—U10 means fewer than 10 scallops per pound. The meat should be creamy white to light tan, never bright white.

Sea scallops are perfect for searing. Get the pan very hot, add fat, and sear the scallops without moving them for 2-3 minutes until a golden crust forms. Flip and cook for 1-2 minutes more. The center should be just barely opaque.

Dry vs. Wet Scallops: This is crucial. Wet scallops have been treated with sodium tripolyphosphate (STP), which makes them absorb water. They weigh more (so you pay for water), they exude liquid when cooked (making searing impossible), and they taste odd.

Dry scallops are untreated. They sear beautifully, taste sweet and clean, and are worth the higher price. Always ask if scallops are dry or wet. If your fishmonger doesn’t know, that’s a bad sign.

Dry scallops should smell sweet and oceanic. They shouldn’t be sitting in milky liquid. They should look somewhat translucent, not opaque white.

Diver Scallops: Hand-harvested by divers rather than dredged. This is more sustainable (less bottom disturbance) and produces beautiful scallops, but they’re expensive. Worth it for special occasions.

Cooking Scallops: The key to perfect scallops is high heat and minimal movement. Pat them completely dry (moisture prevents browning). Season with salt and pepper. Heat a heavy skillet until it’s almost smoking. Add fat (butter, oil, or both). Add scallops with space between them. Don’t touch them for 2-3 minutes. The crust should be deep golden before you flip. Cook the other side for 1-2 minutes. Remove from heat. They’re done when barely opaque in the center.

Scallops are also excellent raw in ceviche or crudo, or briefly broiled with butter and herbs. But that perfect sear—golden crust, barely cooked center—is the preparation that shows off their sweet, delicate nature best.

Crustaceans: Lobster, Crab, and Shrimp

Crustaceans—animals with segmented shells and jointed legs—include some of the most prized seafood. They’re also among the most fun to eat, often requiring hands-on work to extract meat from shells, turning dinner into an interactive experience.

Lobster

Maine lobster (American lobster) is iconic for good reason. The meat is sweet, tender, and briny. The ritual of cracking into a whole lobster—the claws, the tail, the knuckles, even the body—rewards effort with incredible flavor.

Hard Shell vs. Soft Shell: Lobsters molt as they grow, shedding their shell and forming a new, larger one. Right after molting, they’re “shedders” or “soft-shell” lobsters. The new shell is thin and easy to crack (you can often do it with your hands), but the meat doesn’t fill the shell completely and can be watery. Hard-shell lobsters have fully formed shells that require crackers to open, but the meat is denser and sweeter.

Soft-shell lobsters are generally cheaper and available in summer. Hard-shell lobsters are available year-round and are better for shipping since the hard shell protects the meat.

Humane Handling: There’s ongoing debate about whether lobsters feel pain. While we don’t know for certain, treating them humanely seems right regardless. If boiling, use plenty of rapidly boiling water to minimize cooking time. Some cooks kill the lobster instantly with a knife through the head before cooking. Freezing for 15-20 minutes before cooking makes them sluggish and less reactive.

Cooking Lobster: Boiling and steaming are traditional. For boiling, use a huge pot of heavily salted water (it should taste like the sea). Bring to a rolling boil, add lobsters, and cook for about 12-15 minutes for a 1.5-pound lobster. The shell turns bright red when done.

Steaming is gentler and some people prefer it. Use a couple inches of seawater or salted water in a large pot with a steamer insert. Steam for about 15 minutes for a 1.5-pound lobster.

Grilled lobster is wonderful—split lengthwise, brushed with butter, grilled flesh-side down briefly then flipped to finish. The meat gets slightly smoky while staying tender.

The Parts: Claws have sweet, tender meat. The tail has the largest pieces of meat and is the prized section for lobster rolls. Knuckles (the joints connecting claws to body) have some of the sweetest meat but are work to extract. The body contains tomalley (green liver) and roe (bright red eggs in females), both of which some people love and others avoid.

Spiny Lobster: Found in warmer waters (Caribbean, Florida, California), spiny lobsters have no claws—all the meat is in the tail. The flavor is similar to Maine lobster but slightly different. They’re excellent grilled.

Crab

Crab varieties are regional, and each has its passionate devotees and traditional preparations.

Blue Crab: The crab of the Chesapeake Bay and Mid-Atlantic, blue crabs are the basis for crab cakes, crab imperial, and hard-shell crab feasts where you crack them open and pick out the sweet meat. They’re sold live (hard-shell), as picked meat (lump, backfin, or claw), or as soft-shell crabs.

Soft-shell crabs are blue crabs caught just after molting, when the new shell is still soft. They’re cleaned, dusted with flour, and fried whole—shell and all. The entire crab is edible. It’s a delicacy with a short season (late spring through summer).

Picking hard-shell blue crab is an art. You remove the top shell, clean out the gills and innards, then systematically crack and pick meat from the body chambers, claws, and legs. It’s messy, time-consuming work, but the sweet meat is worth it. Traditionally done at outdoor picnic tables covered with newspaper, with Old Bay seasoning and cold beer.

Dungeness Crab: The Pacific Coast’s pride, Dungeness crab is larger than blue crab with particularly sweet meat. The whole crab is boiled or steamed, then cracked and picked. In San Francisco, cioppino (seafood stew) features Dungeness crab prominently.

Dungeness is seasonal (winter through early summer) and the opening of the season is a big deal in coastal California and Oregon. The meat is delicate and sweet, perfect with simple preparations—melted butter, lemon, maybe aioli.

King Crab and Snow Crab: From Alaska, these cold-water crabs have long legs with abundant meat. Most king crab and snow crab sold in the U.S. is already cooked and frozen. You’re essentially reheating it rather than cooking it.

The legs are split and the meat pulled out in long, satisfying pieces. The flavor is rich and sweet. They’re expensive—a special occasion indulgence. Be gentle when reheating so you don’t make the meat rubbery.

Stone Crab: A Florida specialty, stone crab has an unusual sustainable practice: only the claws are harvested. The crab is caught, one claw is removed, and the crab is returned to the water where it will regenerate the claw. The claws are cooked immediately after harvest (they’re always sold cooked), then served cold with mustard sauce.

Stone crab season runs October through May. The meat is sweet and firm. It’s expensive but the sustainable harvesting method makes it more appealing than some seafood.

Shrimp and Prawns

Shrimp is America’s favorite seafood—versatile, quick-cooking, and widely available. Understanding what you’re buying makes a huge difference.

Size Classifications: Shrimp are sold by count per pound: U10 (under 10 per pound, very large), 16/20 (16-20 per pound), 31/40, 51/60, etc. Larger shrimp are more expensive but also more impressive on the plate and easier to work with.

Wild vs. Farmed: Wild-caught shrimp from the Gulf of Mexico, the Pacific, or Alaska tend to have better flavor and firmer texture. Farmed shrimp varies wildly—some operations are responsibly run, others are environmental disasters with heavy chemical use.

Look for certifications like BAP (Best Aquaculture Practices) or ASC (Aquaculture Stewardship Council) on farmed shrimp. Wild-caught U.S. shrimp is generally a safer bet but is more expensive.

Fresh vs. Frozen: Most “fresh” shrimp at the fish counter were frozen and thawed. Truly fresh shrimp (never frozen) are rare unless you’re near the Gulf Coast or buying directly from boats. Buying frozen shrimp and thawing them yourself gives you more control.

Head-on vs. Headless: Shrimp heads contain flavorful fat. In many cuisines, head-on shrimp are preferred and the heads are used for stock or eaten (sucking the juice from the head is prized in some cultures). Headless shrimp are more common in U.S. markets and easier to deal with.

Shell-on vs. Peeled: Shell-on shrimp have better flavor and texture. The shell protects the meat during cooking and adds flavor. Peeled shrimp are convenient but less flavorful. For most applications, shell-on is worth the minor extra work.

Deveining: The dark “vein” is actually the digestive tract. In smaller shrimp it’s fine to leave. In larger shrimp, removing it is both aesthetic and textural—the grit can be unpleasant. Make a shallow cut along the back of the shrimp and rinse out the vein, or use a deveining tool.

Cooking Shrimp: Shrimp cook very quickly—a few minutes in most applications. They’re done when they turn pink/orange and form a C shape. If they curl into an O, they’re overcooked and will be rubbery.

Shrimp are wonderful grilled, sautéed, boiled, steamed, fried, or added to soups and stews. They work in virtually every cuisine—American shrimp cocktail, Asian stir-fries, Italian scampi, Spanish gambas al ajillo, Southern shrimp and grits, Mexican camarones, Thai curry, Indian tandoori.

Prawns: Technically a different animal (prawns have claws, shrimp don’t), but in the U.S. market, “prawn” usually just means large shrimp. Spot prawns from the Pacific Northwest are true prawns and are exceptionally sweet.

Cephalopods: Squid, Octopus, and Cuttlefish

Cephalopods can seem intimidating, but they’re delicious when prepared correctly and offer different textures and flavors than fish or shellfish.

Squid (Calamari)

Squid is the most accessible cephalopod. It’s affordable, widely available, and quick-cooking. The challenge is texture—cooked perfectly, it’s tender. Overcooked even slightly, it becomes rubbery.

The solution: cook it very quickly (flash-fried or quickly sautéed) or very slowly (braised for 30+ minutes). Anything in between will be tough.

Cleaning Squid: Pull the head and tentacles out of the body (the tube). Cut the tentacles off just below the eyes. Remove the beak (hard ball) from the center of the tentacles. Pull out the quill (clear plastic-like structure) from inside the tube. Peel off the purple membrane from the outside of the tube. You’re left with a clean tube and tentacles ready to cook.

Many fish markets sell cleaned squid, which saves considerable time.

Cooking Squid: For frying, slice the tube into rings, dust with flour or cornmeal, and fry in hot oil for 2-3 minutes. They should be golden and tender. This is classic fried calamari, often served with marinara or aioli.

For stir-frying, cut the tube into pieces, score them (creates a nice texture), and cook over very high heat for just a minute or two.

For braising, cut the squid into pieces and simmer in tomato sauce or wine for 30-45 minutes until tender. Mediterranean stews often include squid cooked this way.

Grilled squid is wonderful—brush with olive oil, grill over high heat for 2-3 minutes total, serve with lemon.

Octopus

Octopus needs tenderizing. Traditionally, this was done by beating it against rocks. Modern methods include freezing (ice crystals break down connective tissue), adding wine corks to the cooking water (enzymes help tenderize), or simply slow cooking.

Cooking Octopus: Simmer in water (or wine, or both) with aromatics for 45-90 minutes depending on size. The octopus is done when a knife slides in easily. Let it cool in the liquid, then cut it up and grill or sear it to add char and texture.

In Greek cooking, grilled octopus is classic—tender pieces with charred edges, olive oil, lemon, oregano. In Spanish cooking, Galician-style octopus is boiled until tender, sliced, then served with olive oil, paprika, and coarse salt. In Japanese cooking, octopus shows up in sushi, salads, and stews.

The texture should be tender but with some resistance—not mushy, not rubbery. When it’s cooked right, octopus is wonderful—meaty, flavorful, satisfying.

Cuttlefish

Similar to squid but thicker and meatier, cuttlefish requires similar cooking—very quick or very slow. It’s common in Mediterranean and Asian cooking but less common in U.S. markets.

Cuttlefish ink is prized for pasta and risotto—it adds deep black color and briny, complex flavor. Squid ink can be used the same way. You can buy ink separately or extract it from whole cuttlefish or squid.

Selecting Fresh Seafood: What to Look For

Freshness is everything with seafood. The difference between truly fresh fish and fish that’s a few days old is dramatic. Here’s how to evaluate what you’re buying.

Signs of Freshness in Whole Fish

Eyes: Should be clear, bright, and bulging. Cloudy, sunken eyes indicate age. This is one of the most reliable indicators.

Gills: Lift the gill cover and look inside. Gills should be bright red or pink, never brown or gray. Fresh fish has red gills, period.

Smell: Fresh fish smells like clean ocean—slightly briny, not unpleasant. There shouldn’t be a “fishy” smell. If it smells ammonia-like or strongly fishy, it’s not fresh.

Flesh: Press the flesh near the back. It should be firm and spring back. If your finger leaves an indentation, the fish is old.

Skin: Should be bright, shiny, and metallic-looking with scales intact. Dull, dry skin indicates age.

General Appearance: The fish should look alive—bright colors, taut skin, clean appearance. If it looks sad and tired, it is.

Signs of Freshness in Fillets

Color: Should be vibrant and appropriate for the species. White fish should be translucent and glistening. Salmon should be deep-colored (though color varies by species). Discoloration, especially browning at edges, is a bad sign.

Texture: Flesh should look firm and compact, not separating or flaking. No gaps between muscle segments.

Moisture: Should look moist but not wet. Pooled liquid or excessive wetness often indicates that the fish was frozen and is now releasing water.

Smell: Same as whole fish—clean ocean smell, nothing strong or unpleasant.

Signs of Freshness in Shellfish

Live Shellfish: Clams, mussels, and oysters should be alive when purchased. That means shells are tightly closed or close when tapped. Any that won’t close are dead and should be discarded.

Smell: Should smell like clean ocean. Ammonia or sour smells mean they’re dead or dying.

Lobsters and Crabs: Should be active. Sluggish is okay (they’re cold), but they should respond when touched. Dead lobsters or crabs deteriorate very quickly and shouldn’t be eaten.

Shrimp: Firm texture, no black spots (unless they’re a species that naturally has spots), mild ocean smell. Soft or mushy shrimp are old.

Questions to Ask Your Fishmonger

A good fishmonger is a valuable resource. Building a relationship and asking questions helps you get the freshest, best seafood.

“When did this come in?” You want fish caught yesterday or today if possible. Fish that came in three days ago is getting old.

“What’s the freshest thing you have today?” This often reveals what they’re excited about and what really just came in.

“Wild or farmed?” Know what you’re buying and make informed decisions.

“Previously frozen?” There’s nothing wrong with previously frozen fish if it was frozen properly, but you should know so you don’t refreeze it.

“Where was this caught?” Origin matters for both sustainability and flavor.

“Do you have any off-menu cuts?” Collars, cheeks, belly flaps—sometimes they have great cuts that aren’t displayed.

A knowledgeable fishmonger will answer all these questions happily. Someone who doesn’t know or acts annoyed that you’re asking? Find a different source.

Frozen vs. Fresh: Rethinking Assumptions

Fresh isn’t always better. Fish frozen at sea immediately after catching can be higher quality than “fresh” fish that’s been sitting on ice for days. Modern flash-freezing preserves texture and flavor remarkably well.

If buying frozen fish, look for: – Tightly sealed, undamaged packaging – No ice crystals (indicates thawing and refreezing) – No freezer burn (dry, discolored patches) – Recent freeze date if available

Thawing Frozen Fish: Slow thawing in the refrigerator is best. Put the fish on a plate (to catch any liquid) and let it thaw overnight. Quick thawing in cold water (in a sealed bag) works if you’re rushed. Never thaw at room temperature and never refreeze previously frozen fish.

Seasonality Matters

Like produce, seafood has seasons. Some fish spawn at certain times and shouldn’t be harvested then. Some shellfish are better in cold months. Some areas close fisheries seasonally to allow populations to recover.

Salmon runs happen at specific times. Soft-shell crabs are a late spring/summer phenomenon. Stone crab season is October through May. Wild striped bass season changes based on population levels.

Asking what’s in season and buying accordingly often gets you the best quality at the best price. It also supports sustainable fishing by respecting natural cycles.

Storage and Handling: Keeping Seafood Safe and Fresh

Seafood is more perishable than most other proteins. Proper storage is essential for safety and quality.

Storing Fresh Fish

Fish should be kept as cold as possible without freezing—ideally around 32°F. Your refrigerator is probably closer to 38-40°F, so you need to create a colder environment.

The Method: Put the fish in a colander or on a rack set over a plate or tray. Cover it with ice. Put the whole setup in the coldest part of your refrigerator (usually the back of the bottom shelf). Replace the ice as it melts.

The key is drainage—you don’t want the fish sitting in melted ice water, which will make it mushy and wash out flavor. The colander or rack keeps it above the liquid.

How Long It Keeps: Really fresh fish should be cooked within 24 hours. Fish that was already a day or two old when purchased should be cooked that evening. When in doubt, smell it—if it smells fishy or off, it’s past its prime.

Storing Shellfish

Live Clams, Mussels, Oysters: They’re alive and need to breathe. Store them in the refrigerator covered with a damp towel—never sealed in plastic or submerged in water (fresh water will kill them). They’ll keep for several days if properly stored, though fresher is always better.

Live Lobsters and Crabs: Ideally cooked the day of purchase. If you must store them, keep them very cold in a cooler or in the refrigerator covered with damp newspaper or seaweed. Don’t put them in fresh water.

Shucked Shellfish (Oysters, Scallops): Keep in their liquor (liquid) in the coldest part of the refrigerator. Use within 1-2 days.

Cooked Shellfish: Store in airtight containers in the refrigerator. Use within 3-4 days. Cooked shrimp, picked crab meat, and cooked lobster meat all keep reasonably well refrigerated.

Freezing Seafood at Home

If you can’t cook fish within a day or two, freezing is better than letting it deteriorate in the refrigerator.

Method for Fish: Wrap tightly in plastic wrap, then in aluminum foil, then in a freezer bag, pressing out all air. The multiple layers protect against freezer burn. Label with the date.

How Long It Keeps: Lean white fish keeps for 6 months frozen. Oily fish (salmon, mackerel) keeps for 2-3 months before the fat starts to oxidize and taste off.

Shellfish: Shrimp freeze well and are often sold frozen anyway. Lobster and crab meat can be frozen if cooked first. Clams and mussels can be frozen in their shells, though texture suffers slightly.

The Truth About Freezing: Properly frozen seafood is better than old “fresh” seafood. If you can’t cook it fresh, freeze it without guilt.

Food Safety

Seafood can harbor bacteria and parasites that proper handling and cooking destroy.

Safe Internal Temperatures: The FDA recommends cooking fish to 145°F. At this temperature, the flesh is opaque and flakes easily. Many people prefer fish cooked to lower temperatures (tuna, salmon), which is generally safe with very fresh, high-quality fish but does carry some risk.

Raw Consumption: Sushi, sashimi, ceviche, and raw oysters all carry risks. The fish should be “sushi-grade” or “sashimi-grade” which indicates it was frozen to kill parasites. Raw oysters can harbor vibrio bacteria, especially in warm months. People with compromised immune systems should avoid raw seafood.

Shellfish Safety: Never eat clams, mussels, or oysters that don’t open during cooking—they were dead before cooking and could make you sick. Similarly, never eat dead lobsters or crabs.

Cross-Contamination: Keep raw seafood away from ready-to-eat foods. Wash cutting boards, knives, and hands thoroughly after handling raw seafood.

Cooking Methods by Seafood Type

Different types of seafood respond better to different cooking methods. Understanding these relationships helps you get the best results.

Delicate White Fish (Sole, Flounder, Cod, Halibut)

Pan-Searing: This is the technique used in the cod recipe on this site. Heat a pan until very hot, add fat, season the fish, place it in the pan presentation-side down. Don’t move it until it releases easily and has a golden crust (3-4 minutes). Flip carefully and cook the other side briefly. The fish is done when it’s just opaque in the center.

Poaching: Gentle cooking in barely simmering liquid (water, wine, court bouillon, milk). This keeps delicate fish moist and tender. The fish is done when it flakes easily and is opaque throughout.

En Papillote: Wrapping fish in parchment with vegetables, herbs, and liquid, then baking. The packet steams the fish gently while capturing all the flavors. It’s elegant presentation too—the packet puffs up and releases aromatic steam when opened.

Light Frying: Dredging in flour or breading and pan-frying in shallow oil. This is classic fish and chips, fish tacos, or schnitzel-style fish. The breading protects the delicate flesh and adds texture.

Oily/Fatty Fish (Salmon, Tuna, Mackerel, Bluefish)

Grilling: The fat keeps these fish moist during high-heat grilling. Skin-on fillets or steaks work best—the skin prevents sticking. Oil the grill well, place the fish skin-side down, don’t move it until it releases. For salmon, you can often cook it entirely on the skin side, letting residual heat gently cook the top.

Broiling: Similar to grilling but from above. Position the fish close to the broiler and watch carefully—it cooks fast. Great for getting charred edges while keeping the center rare (for tuna) or perfectly cooked (for salmon).

Roasting: High heat (425-450°F) roasts fish quickly while developing flavor. Oily fish stays moist even at high heat. Season generously, maybe add a glaze or topping, roast until just done.

Smoking: Hot smoking or cold smoking both work beautifully with oily fish. Smoked salmon, smoked mackerel, smoked trout—the fat carries smoke flavor wonderfully.

Shellfish Cooking

Steaming Clams and Mussels: Aromatics (garlic, shallots, herbs) and liquid (wine, beer, broth) go in a pot. Bring to a simmer, add shellfish, cover, and steam for 5-7 minutes until shells open. Serve with the flavorful broth.

Boiling Lobster and Crab: Large pot of heavily salted boiling water. Add lobsters or crabs, cover, return to boil, cook for 12-15 minutes for 1.5-pound lobsters. The shells turn bright red when done.

Searing Scallops: Dry scallops thoroughly, season, heat pan until almost smoking, add fat, add scallops with space between them, don’t touch for 2-3 minutes, flip, cook 1-2 minutes more. The crust should be deep golden.

Sautéing Shrimp: Medium-high heat, fat in pan, add shrimp in a single layer, cook for 2-3 minutes per side until pink and C-shaped. Don’t overcrowd the pan or they’ll steam instead of sear.

Squid and Octopus

Quick Searing: Very hot pan, oil with a high smoke point, squid pieces in the pan for 1-2 minutes total. The squid should barely cook through—any longer and it toughens.

Long Braising: Squid or octopus simmered in sauce for 30-45 minutes becomes tender again after going through the tough stage. This is how Mediterranean seafood stews tenderize cephalopods.

For Octopus: Simmer until tender (45-90 minutes), cool in the liquid, then grill or sear for texture and char.

Whole Fish Cooking

Roasting Whole: Stuff the cavity with herbs, lemon, aromatics. Brush with oil, season generously. Roast at 400-425°F for 20-30 minutes depending on size. The fish is done when the flesh pulls away from the bones easily.

Grilling Whole: Oil the fish and grill grates well. Score the skin in a few places (prevents curling). Grill over medium-high heat, flipping carefully halfway through. Use a fish basket if you’re nervous about it falling apart.

Steaming: Traditional in Chinese cooking. The whole fish is steamed with ginger and scallions, then finished with hot oil and soy sauce. The flesh stays incredibly moist and delicate.

Global Seafood Traditions: How Different Cultures Honor the Ocean

Every coastal culture has developed unique relationships with seafood, creating dishes and techniques that reflect local species, values, and history.

New England

Clam Chowder: The creamy, potato-laden soup is New England’s gift to American cuisine. True New England chowder is white—made with clams, potatoes, onions, salt pork or bacon, and cream. Manhattan-style with tomatoes is a different dish entirely, and suggesting you might add tomatoes to New England clam chowder is fighting words in some circles.

Lobster Rolls: Split-top hot dog buns griddled in butter, filled with chunks of lobster meat dressed lightly with mayonnaise or melted butter. Connecticut does warm lobster rolls with butter, Maine does cold lobster rolls with mayo, and both claim to have invented it. The truth is they’re both delicious.

Fish and Chips: While British in origin, fish and chips became thoroughly New England through the Portuguese and Irish communities. Fried haddock or cod with thick-cut fries, coleslaw, and tartar sauce is Friday night tradition in many New England towns.

Clambakes: Layering seaweed, clams, lobsters, corn, and potatoes in a pit on the beach, covering it, and letting everything steam together. It’s less common than it once was but remains the iconic New England summer gathering.

Mediterranean

Italian Seafood Pasta: Spaghetti alle vongole (with clams), linguine with mussels, seafood risotto. The key is simplicity—let the seafood shine with just olive oil, white wine, garlic, and maybe tomatoes. In coastal Italy, these aren’t fancy restaurant dishes, they’re what you eat at home.

Brodetto: Italian fish stew varies by region. Adriatic versions include multiple types of fish and shellfish in a tomato broth. It’s similar to bouillabaisse but distinctly Italian in its use of vinegar and assertive seasoning.

Spanish Paella: Saffron rice cooked in a wide pan with seafood, chicken, sometimes rabbit, peas, peppers. The socarrat (crispy bottom layer) is prized. True Valencian paella doesn’t include seafood—that’s a coastal variation—but seafood paella is glorious regardless of authenticity arguments.

Galician Octopus: Boiled octopus sliced and served with olive oil, paprika (pimentón), and coarse salt. Simple, perfect, requiring only excellent octopus and proper cooking.

Greek Grilled Fish: Whole fish rubbed with olive oil, oregano, and lemon, grilled over charcoal. Served with more olive oil and lemon, maybe a simple salad. The Greek islands have perfected this approach—no fuss, just pristine fish treated simply.

Bouillabaisse: The iconic fish stew of Marseille. Traditionally made with Mediterranean rock fish, served with rouille (garlicky saffron mayonnaise) and crusty bread. There are formal rules about what makes authentic bouillabaisse, enforced by local restaurants with a certifying board.

Asian Preparations

Japanese Sushi and Sashimi: Raw fish sliced and served with minimal accompaniment—soy sauce, wasabi, pickled ginger. The focus is entirely on the quality and freshness of the fish. Sushi adds vinegared rice, creating different textures and flavors. Years of training go into learning to slice fish properly and prepare perfect sushi rice.

Thai Curries and Grilled Fish: Fish grilled whole with aromatics stuffed inside, served with nam pla prik (fish sauce with chilies). Curries with chunks of fish or whole prawns in coconut-based sauce loaded with lemongrass, galangal, kaffir lime. The balance of spicy, sour, salty, and sweet is essential.

Chinese Steamed Fish: Whole fish steamed with ginger and scallions, then finished with smoking-hot oil poured over to flash-cook the aromatics, and seasoned with soy sauce. The technique keeps the fish incredibly moist while building layers of flavor.

Vietnamese Canh Chua: Sour fish soup with tamarind, pineapple, tomatoes, and catfish or other fish. The interplay of sour, sweet, and savory is characteristic of Vietnamese cooking.

Latin American

Ceviche: Raw fish “cooked” in citrus juice (lime, lemon, or bitter orange). The acid denatures the proteins, firming and opaquing the fish. Peru claims ceviche as its national dish, and coastal Peru makes it perfectly—fresh fish, lime juice, ají peppers, onions, cilantro, sweet potato on the side.

Aguachile: Mexican version of ceviche, particularly from Sinaloa. Raw shrimp in a spicy, bright green sauce of lime, serrano chilies, and cucumber. It’s served almost immediately—barely marinated, very fresh, intensely flavored.

Fish Tacos: Baja California’s contribution to world cuisine. Fried fish in a tortilla with cabbage, crema, salsa, lime. Simple street food that’s become ubiquitous. The fish should be crispy outside, flaky inside, with bright toppings cutting the richness.

Brazilian Moqueca: Fish stew with coconut milk, dendê (palm oil), tomatoes, peppers. The Bahian version is rich and complex. It’s served in a clay pot with rice, celebrating the African influence on Brazilian cuisine.

Nordic Traditions

Gravlax: Salmon cured with salt, sugar, and dill. The fish is buried (gravlax means “buried salmon”) under the cure for a few days, emerging firm, silky, and perfumed with dill. Sliced thin and served with mustard sauce.

Pickled Herring: Herring in vinegar brine with onions, spices, sometimes cream. An acquired taste for many Americans, but beloved in Scandinavia and parts of Northern Europe. The pickling preserves the fish and creates complex, tangy flavors.

Smoked Fish: Cold-smoked salmon, hot-smoked mackerel, smoked eel. Smoking was originally preservation, now it’s flavor. Nordic countries perfected the technique, creating fish that keeps for weeks while developing deep, smoky complexity.

Caribbean

Jerk Fish: Whole fish or fillets rubbed with fiery jerk spice paste, grilled over pimento wood. The spice blend varies by island and by cook, but always includes scotch bonnet peppers, allspice, thyme, and garlic.

Escovitch: Fried fish topped with spicy pickled vegetables—carrots, peppers, onions in vinegar. The combination of crispy fish and acidic vegetables is refreshing in the tropical heat.

Conch Preparations: Conch fritters, conch salad, conch chowder. The large sea snail is a Caribbean staple, beaten tender and prepared in countless ways. Overfishing has made conch less available than it once was.

Sustainability and Ethics: Making Responsible Choices

The ocean isn’t infinite. We’ve learned that lesson painfully through collapsed fisheries and depleted populations. Eating seafood responsibly means understanding these issues and making informed choices.

Understanding Overfishing

Atlantic cod, once so abundant it seemed inexhaustible, collapsed in the 1990s due to overfishing. Bluefin tuna populations are severely depleted from decades of overharvesting for sushi. Swordfish were in danger until strict management helped populations recover.

The pattern is familiar: We find a valuable species, we catch it as fast as we can, technology makes us more efficient, demand increases, and suddenly the fish are gone. Then the fishery collapses, communities lose livelihoods, and recovery takes decades if it happens at all.

Bycatch: Many fishing methods catch unintended species along with the target fish. Turtles, dolphins, sharks, seabirds—all can die as bycatch. Some fishing methods (longlining, trawling with certain gear) have high bycatch. Others (pole-and-line, harpooning, traps) are more selective.

Sustainable Certifications

Marine Stewardship Council (MSC): Certifies wild fisheries that meet sustainability standards. Look for the blue MSC logo. It’s not perfect, but it indicates the fishery is managed with sustainability in mind.

Best Aquaculture Practices (BAP): Certifies farmed seafood operations meeting environmental and social responsibility standards. Aquaculture varies wildly in quality—BAP certification suggests better practices.

Monterey Bay Seafood Watch: Publishes guides (and an app) rating seafood as “Best Choice,” “Good Alternative,” or “Avoid” based on sustainability. It’s updated regularly and region-specific.

Aquaculture: Promise and Problems

Fish and shellfish farming can be sustainable or it can be environmental disaster, depending on the species and methods.

Shellfish Farming Benefits: Oysters, clams, and mussels filter water as they grow, actually cleaning the environment. They don’t require feed (they filter-feed naturally). They don’t require antibiotics. Shellfish farming is generally good for ecosystems.

Finfish Farming Issues: Salmon farming can involve crowded pens, disease, parasites (sea lice), antibiotics, pollution from concentrated waste, and escapees that can harm wild populations. Some operations are much better than others.

Land-based recirculating systems are emerging as better alternatives—fish raised in tanks with water filtration and recycling. It’s more expensive but potentially more sustainable.

Making Sustainable Choices

Eat Lower on the Food Chain: Small fish like sardines, anchovies, and mackerel are more sustainable than large predators like tuna and swordfish. They reproduce faster, populations are more stable, and they don’t accumulate as much mercury.

Choose Seasonal and Local: Fish caught in season and close to home requires less energy to bring to market. It’s also often fresher and cheaper.

Try Lesser-Known Species: Everyone wants salmon and tuna. Fewer people eat pollock, hake, or dogfish, even though they’re delicious and more abundant. Markets follow demand—if people buy sustainable species, more will be available.

Ask Questions: Where was this caught? How was it caught? Is there a more sustainable option? Good fishmongers will know and will appreciate customers who care.

Mercury and Contaminants

Large predatory fish accumulate mercury through biomagnification—they eat smaller fish that contain mercury, concentrating it in their bodies over time.

High Mercury Fish (limit consumption): Shark, swordfish, king mackerel, tilefish, bigeye tuna. Pregnant women and young children should avoid these entirely.

Moderate Mercury: Albacore tuna, halibut, striped bass. Eat occasionally but not frequently.

Low Mercury: Salmon, sardines, scallops, shrimp, pollock, catfish. Safe to eat regularly.

The health benefits of seafood generally outweigh mercury concerns for most people, but making informed choices matters, especially for vulnerable populations.

Essential Techniques: Skills Worth Learning

These techniques transform you from someone who buys fillets to someone who can handle whole fish and shellfish with confidence.

Filleting a Whole Fish

Start with a round fish (like bass or trout). You’ll need a sharp, flexible filleting knife.

1. Scale the fish if necessary (scrape from tail toward head with the back of a knife or a fish scaler). 2. Make a diagonal cut behind the head, down to the backbone. 3. Turn the knife parallel to the cutting board and slice along the backbone from head to tail, keeping the knife against the bones. 4. The fillet should come away in one piece. Flip the fish and repeat on the other side. 5. Remove pin bones with tweezers or clean pliers. 6. If desired, remove the skin by placing the fillet skin-side down, holding the tail end, and slicing between flesh and skin while pulling the skin taut.

It takes practice. Your first few attempts won’t be pretty. That’s fine—even messy fillets cook up just fine.

Shucking Oysters

You need an oyster knife and patience.

1. Hold the oyster in a towel with the hinge (pointed end) exposed, cup-side down. 2. Work the knife tip into the hinge, wiggling gently until you feel it pop. 3. Slide the knife along the inside of the top shell to cut the adductor muscle. 4. Remove the top shell, being careful not to spill the liquor. 5. Slide the knife under the oyster to detach it from the bottom shell. 6. Check for shell fragments before serving.

Keep the oyster as level as possible throughout—that liquor is precious.

Shucking Clams

Similar to oysters but harder because clams grip their shells tighter.

1. Hold the clam with the hinge in your palm. 2. Work the knife between the shells at the seam opposite the hinge. 3. Slide the knife around to cut the adductor muscles on both sides. 4. Open the shell and check for sand or shell fragments.

Or just steam them open, which is much easier and equally delicious.

Cleaning Squid

1. Pull the head and tentacles out of the body tube—the innards come with them. 2. Cut the tentacles off just below the eyes. 3. Find the hard beak in the center of the tentacles and remove it. 4. Pull the quill (clear, plastic-like structure) out of the body tube. 5. Peel off the purplish membrane from the outside of the tube. 6. Rinse everything thoroughly.

You’re left with a clean tube and tentacles ready to cook.

Deveining Shrimp

1. If the shrimp still has the shell, peel it off (leave the tail on if desired). 2. Make a shallow cut along the back of the shrimp. 3. Look for the dark vein (digestive tract). 4. Use the knife tip or your fingers to pull it out. 5. Rinse the shrimp.

For small shrimp, this step is optional. For large shrimp, removing the vein improves both appearance and texture.

Cracking Lobster and Crab

Lobster: 1. Twist the claws off the body. 2. Twist the tail off the body. 3. For the tail, flip it over and cut down the center of the soft underside, then crack it open. 4. For the claws, crack with lobster crackers or the back of a heavy knife, then pull out the meat. 5. The knuckles (joints) can be cracked open for sweet nuggets of meat.

Crab: 1. Remove the top shell. 2. Clean out the gills and innards. 3. Break the body in half. 4. Pick meat from the chambers using your fingers or a small fork. 5. Crack the legs and claws, extract the meat.

It’s messy work. Embrace it. Have plenty of napkins and maybe a bowl of lemon water for your fingers.

Removing Pin Bones

Run your finger along the center of the fillet. You’ll feel the pin bones sticking up. Using clean tweezers or needle-nose pliers, grab each bone and pull firmly at a slight angle (toward the head end of the fish). They should slide out cleanly.

Some fillets have more pin bones than others. Salmon has many. Some fish have few or none.

Skinning a Fillet

1. Place the fillet skin-side down on a cutting board. 2. Hold the tail end firmly. 3. Angle a sharp knife between the flesh and skin at the tail end. 4. While pulling the skin taut, slice along its length, keeping the knife angled down toward the skin. 5. The flesh should separate cleanly from the skin.

This takes a sharp knife and confidence. If you’re nervous, ask your fishmonger to do it.

Troubleshooting and Tips

Preventing Fish from Sticking

Sticking happens when proteins bond to the metal. Prevention: – Make sure your pan is hot before adding the fish – Use enough fat (oil, butter, or both) – Don’t move the fish until it releases naturally (the crust will release when it’s ready) – For grilling, oil both the fish and the grates, and preheat the grill properly

Patience is key. If you try to flip too soon, it will stick. Wait until the fish releases easily.

Knowing When Fish is Done

The 145°F recommendation from food safety agencies produces fish that many people consider overcooked. Here are other indicators: – The flesh turns opaque (changes from translucent to solid white/pink) – The flesh flakes easily with a fork (but before it’s falling apart) – For thick fillets, use an instant-read thermometer inserted into the thickest part – For whole fish, the dorsal fin pulls out easily when it’s done

Many people prefer salmon and tuna cooked to lower temperatures (120-130°F), keeping the center translucent. This is safe with very fresh fish but carries some risk.

Reviving Flavor in Frozen Fish

Frozen fish can lose some flavor. Help it along: – Soak in milk for 20 minutes before cooking (milk proteins bind to the compounds that cause fishiness) – Marinate briefly in acidic liquid (lemon juice, wine) with aromatics – Season aggressively – Use flavorful cooking methods (not plain steaming)

Using Every Part

Fish Stock from Bones: Save fish heads, frames (skeletons), and shrimp shells. Simmer with aromatics for 30-45 minutes to make stock. It’s the base for chowders, soups, risotto, and sauces.

Shellfish Shells: Shrimp, lobster, and crab shells make phenomenal stock. Toast them in oil first to develop flavor, then simmer in water with aromatics.

Fish Collars and Cheeks: Often discarded or overlooked, these cuts are delicious. Ask your fishmonger for them—they’re usually cheap or free.

Reducing Fishy Smell in Your Kitchen

– Dispose of scraps immediately (freeze them until trash day if necessary) – Open windows while cooking fish – Simmer vinegar and water on the stove after cooking to neutralize odors – Clean cutting boards and counters with lemon juice or vinegar – Wash hands with lemon juice to remove fish smell

Conclusion: Building Your Seafood Confidence

There’s a moment when cooking seafood stops being intimidating and becomes exciting. Maybe it’s the first time you perfectly sear a piece of fish, the crust golden and the center just barely cooked through. Maybe it’s successfully shucking your first oyster. Maybe it’s walking into a fish market and knowing what questions to ask, what to look for, how to choose.

That confidence doesn’t come all at once. It builds slowly, through practice and occasional failures. The fish that sticks to the pan, the scallops that won’t sear because they were wet, the lobster you overcook—these aren’t failures, they’re education. You learn more from what goes wrong than from what goes right.

The beautiful thing about seafood is its range. If you’re nervous about cooking whole fish, start with simple fillets. If you’ve never shucked an oyster, ask your fishmonger to do it while you watch. If sustainability concerns overwhelm you, start with one or two easy swaps—sardines instead of tuna, farmed shellfish that you know are raised responsibly.

Build your repertoire gradually. Master one fish before moving to another. Get comfortable with steaming clams before attempting to shuck oysters. Learn to sear scallops before attempting whole grilled fish. There’s no rush. The ocean has been feeding people for millennia—it will wait while you figure things out.

The goal isn’t to become an expert on every species and technique. The goal is to feel comfortable enough to bring seafood into your regular cooking rotation, to try new things, to ask questions, to experiment. Maybe you’ll discover you love cooking whole fish. Maybe you’ll find that quick-seared scallops become your go-to impressive dinner. Maybe you’ll fall in love with simply grilled sardines the way they do them in Portugal.

Along the way, you’re connecting to something larger than just dinner. You’re participating in traditions that span cultures and centuries. You’re supporting fishing communities and aquaculture operations when you buy responsibly. You’re getting some of the healthiest protein available. You’re learning about ecosystems, sustainability, and our relationship with the ocean.

And you’re eating really, really well. Because properly cooked seafood—sweet scallops, briny oysters, flaky white fish, rich salmon, tender clams—this is food that makes you pay attention. It tastes like the ocean, like the specific place it came from, like the care taken to bring it from water to plate.

Start simple. Buy the freshest fish you can find. Ask your fishmonger for advice. Try one new species. Practice one new technique. Cook something that scares you a little. The worst that happens is you learn something. The best that happens is you discover that cooking seafood isn’t mysterious or intimidating—it’s just delicious.

Trust your senses. If the fish looks tired and dull at the market, don’t buy it. If the scallops smell sweet and oceanic, grab them. If something seems off, it probably is. Your eyes, nose, and instincts are excellent guides.

And remember that people have been cooking seafood successfully for thousands of years without culinary degrees or fancy equipment. A sharp knife, a hot pan, good ingredients, and confidence—that’s most of what you need.

The ocean is generous. It offers incredible diversity, remarkable flavors, and endless possibilities. Learning to cook seafood well opens up all of that. It makes you a more versatile cook, expands your palate, and connects you to both tradition and the natural world.

So go ahead. Buy that whole fish you’ve been eyeing. Try shucking oysters. Make a pot of clams with white wine and garlic. Sear those scallops. The techniques are learnable, the ingredients are available, and the results—when you get it right—are absolutely worth the effort.

Welcome to the world of seafood. The water’s fine.
