Ask the Fish Guy: What the Person Behind the Counter Wishes You Already Knew
Walk into a well-stocked fish market and you're surrounded by more culinary knowledge than most cookbooks can hold. The person icing down those fillets and fielding questions about halibut has probably forgotten more about seafood than the average home cook will ever learn. The problem is, most of us don't know how to tap into that knowledge. We point at something, ask if it's fresh, pay, and leave.
We spent time talking with fishmongers at independent markets along the East and West Coasts — people who've built careers at the fish counter — to find out what they'd tell us if we just gave them a few extra minutes. What came back was practical, occasionally surprising, and genuinely useful for anyone who cooks fish at home.
"Fresh" Is More Complicated Than You Think
Let's start with the word that causes the most confusion: fresh.
"Customers come in asking for the freshest fish, which makes sense," says Marcus, who runs the seafood department at a specialty grocery in Portland, Maine. "But what they usually mean is 'not frozen,' and those aren't the same thing at all."
He's right, and it's a distinction worth internalizing. A fish caught in Alaska and flash-frozen at sea within hours of harvest is often in better condition than a "fresh" fish that's been sitting in a hold, on ice, and in transit for five or six days before landing on a retail counter. Freezing technology has improved dramatically, and a well-handled frozen product — thawed properly in the refrigerator overnight — can be indistinguishable from, or even superior to, the never-frozen alternative.
"I tell people: don't fear the frozen section," Marcus adds. "Fear the unlabeled stuff with no information about where it came from or when it was caught."
The markers of genuine freshness, when you're buying fish that hasn't been frozen, are pretty consistent across species. Clear, bright eyes on whole fish (cloudy means time has passed). Firm flesh that springs back when pressed. A smell that reads as ocean or clean water — not fishy, not ammonia-like. Gills that are vivid red or pink, not gray or brown. And fillets that look moist and translucent, not dried out at the edges.
The Seasonal Calendar Your Grocery Store Ignores
One of the most consistent complaints from fishmongers is that retail grocery chains have trained American consumers to expect the same fish year-round, regardless of what's actually running.
"People want salmon in February and striped bass in January," says Diane, who works at a family-owned fish market on the Massachusetts North Shore. "And we can get them those things, technically. But it's usually not the best version of that fish."
Seasonal availability varies significantly by region, but some general patterns hold. Wild Pacific salmon runs peak in summer and early fall — king salmon from Alaska is at its richest from late May through September. Atlantic striped bass has a spring and fall season along the Northeast coast. Gulf shrimp are sweetest in late summer and early fall. Dungeness crab from the Pacific Northwest hits its stride in winter. Soft-shell blue crabs from the Chesapeake appear in late spring through early summer.
The practical advice from every fishmonger we spoke with was the same: ask what's good right now, not what you planned to make before you walked in. The answer to that question will almost always point you toward something in peak condition at a fair price.
"If I'm excited about something when you walk in, let me tell you about it," Diane says. "That excitement means it just came in, it looks great, and I know exactly what to do with it."
The 'Sushi-Grade' Label Doesn't Mean What You Think
This one comes up constantly, and the answer is almost always a little deflating.
"There's no regulatory standard for 'sushi-grade' or 'sashimi-grade' in the United States," explains Kevin, a fishmonger at a Seattle market with a strong Japanese-American clientele. "Any retailer can put that label on anything. It's a marketing term, not a safety certification."
What the FDA does regulate is a freezing protocol designed to kill parasites — specifically, holding fish at -4°F for seven days, or -31°F for 15 hours — that reputable suppliers follow for fish intended to be eaten raw. But the label on the package doesn't guarantee that protocol was followed, and the absence of the label doesn't mean the fish is unsafe.
The real answer, according to Kevin and others, is relationship and trust. When you know your fishmonger, you can ask directly: "Is this fish appropriate for eating raw? Was it handled for that purpose?" A straight answer to that question is worth more than any label.
"If someone can't answer that question confidently, that's information too," Kevin says.
Building a Relationship That Pays Off
Every fishmonger we spoke with circled back to the same theme: regulars get better service, better fish, and better information. Not because fish counter professionals play favorites, but because knowing what a customer likes and how they cook allows them to make genuinely useful recommendations.
The mechanics of building that relationship are simple.
Introduce yourself, or at least make eye contact and engage. Ask questions, even basic ones — nobody at a fish counter is annoyed by curiosity. Tell them how you're planning to cook the fish and what flavors you're working with. Let them know what you liked and what didn't work last time. Over a few visits, that back-and-forth creates a shorthand that benefits everyone.
"My best customers are the ones who tell me when something wasn't great," says Diane. "That's how I know what to look for next time. And honestly, those are the people I'm going to call when something exceptional comes in."
That last part — the phone call when something exceptional arrives — is one of the underappreciated perks of being a regular at a good fish market. Limited quantities of outstanding product (a particularly beautiful whole striped bass, the first local halibut of the season, live sea urchin from a local diver) often don't make it to the general display case. They go to the people the staff knows will appreciate them.
A Few More Things Worth Knowing
Beyond the big themes, a handful of practical tips came up repeatedly in our conversations.
Buy whole fish when you can. A whole fish is easier to assess for freshness than a fillet, and the yield is often better than people expect. Ask your fishmonger to clean and fillet it if you're not comfortable doing it yourself — most are happy to.
Don't overlook underutilized species. Porgy, bluefish, mackerel, and skate are often fresher, cheaper, and more sustainably sourced than the marquee options. They're also genuinely delicious when handled right.
Timing matters at the counter. Mid-week mornings, after delivery days, are typically when inventory is freshest at most retail fish counters. Friday afternoon, when everyone is shopping for the weekend, is usually when you're working with older stock.
Ask about prep. Most fish counters will marinate, season, or portion fish to your specifications at no extra charge. It's a service that's wildly underused.
The fish counter is one of the last places in American food retail where genuine expertise is standing right in front of you, ready to help. All you have to do is ask.
