What a Catch
Lobster and tuna and barramundi—oh my! Standing in front of the fish counter isn’t as easy as it used to be. Tuna or tilapia, salmon or sardines, farmed or wild, fresh or frozen—the choices are enough to make my head swim … I mean spin. Plus, I’m nursing a newborn, and it just seems easier to skip seafood altogether instead of making the wrong choice.
But I can’t, because I know both my baby and I can benefit from the heart-healthy, brain-boosting omega-3s found in fish, not to mention the good-for-you nutrients like vitamin D, selenium, zinc, and protein. I want my son to grow up in a world that still has wild seafood, a stock some experts say could be depleted by 2048. That’s why it’s more important than ever to pick sustainable seafood from responsible fisheries that limit bycatch (unintentional catches that are often unwanted and go unused) and don’t damage the surrounding environment. But without an eco-expert at my beck and call, how do I know what types of fish are best for my family?
Rather than get frustrated, I decided to get educated and go to the experts—scientists, nutritionists, and chefs—in order to separate fish fact from fiction.
Myth #1: The downsides of mercury outweigh the benefits of fish.
Truth: The health boost you get from omega-3s trumps possible toxins.
If fear of mercury is stopping you from eating seafood, rest assured that the heart-healthy omega-3 fatty acids found in fish, especially cold-water, oily species like salmon and sardines, outweigh the risks. Omega-3s do more than tune up your ticker; they reduce inflammation in the body, fight depression, help burn fat, improve cognitive function, and repair dry skin, says Esther Blum, RD, a holistic nutritionist and author of Secrets of Gorgeous (Chronicle Books, 2008). Studies also show that the essential fatty acids in fish, notably DHA, help nourish a baby’s developing brain and may decrease the risk of delivering a preterm, low birth-weight baby.
You can get too much mercury, but most experts agree you’d have to eat high-mercury varieties like swordfish, shark, mackerel, tilefish, and tuna at least once a week to experience symptoms, which range from tingling in the hands and feet to memory loss and neurological dysfunction, says Steven Masley, MD, clinical assistant professor at the University of South Florida.
The bottom line? Don’t ditch fish if you’re pregnant or worried about mercury, but do skip mercury heavyweights in favor of two 12-ounce servings a week of flounder, herring, haddock, shrimp, catfish, farm-raised trout, sardines, or wild Pacific salmon. And remember: Variety is the spice of life when it comes to seafood. “Even if you don’t know the specific contaminant level in the fish that you buy, you’re much more likely to minimize your risk of toxin and mercury exposure if you buy several different species instead of just one,” says Tim Fitzgerald, a marine scientist for the Environmental Defense Fund.
Myth #2: Fisheries—not consumers—are depleting the fish supply.
Truth: The seafood you eat (and avoid) can make a difference.
Can just one person—or one fish choice—impact the sustainability of our fish supply? “Absolutely,” says Fitzgerald. “The crisis in the oceans right now in terms of overfishing and collapsing fish populations is as much a product of consumer demand as it is the regulations that govern fisheries.”
So what’s a concerned consumer to do? The first step is to download a wallet-sized fish-advisory card from the Environmental Defense Fund (oceansalive.org) so you’ll know which farmed and wild fish to pick—and which to skip—for your health and the planet’s. And when you go out to eat, read the menu (or ask the waitstaff) to find out how the restaurant purchases its fish. “Look at the way the restaurant procures a lot of its other food,” says Kristofor Lofgren, owner of Bamboo Sushi in Portland, Oregon, the first Marine Stewardship Council–certified independent restaurant in the US. “If they support local, organic farms, generally speaking they’re going to support better-quality fish practices.”
Myth #3: All farmed fish are bad for the environment.
Truth: Not all farmed fish are environmental evils.
Many types of seafood are actually farmed in a responsible way, says Fitzgerald; it’s farmed salmon that gives aquaculture a bad name. Often raised in crowded ocean cages and treated with antibiotics and pesticides to control parasites and disease, farmed salmon has PCB levels up to 10 times higher than wild salmon, according to some studies. These known carcinogens are concentrated in the fish-meal feed.
“Farmed salmon requires the use of lots of wild fish that fisheries catch and grind up to put into the feed,” says Fitzgerald, who notes that many fisheries use 3 to 6 pounds of wild fish for 1 pound of farmed salmon. In fact, 37 percent of all seafood is ground up into feed, up from 7.7 percent in 1948, according to the Fisheries Centre at the University of British Columbia.
But don’t let salmon sour your taste for all farmed fish. US-farmed tilapia and catfish get an eco check mark because they require less fish for their feed. Farm-raised mussels and clams, which are grown without chemicals and antibiotics, are also good choices. Ditto for fish raised responsibly in ponds or tanks where wastewater is contained and controlled.
Myth #4: There’s nothing you can do to cut down on mercury in fish.
Truth: Choosing the right fish and cooking it the right way can lighten the toxic load.
Generally speaking, the smaller the fish, the better. “Larger fish such as king mackerel, shark, swordfish, tilefish, and tuna tend to accumulate a higher concentration of mercury because of their consumption of organisms high on the food chain,” says Masley. Smaller species, like salmon and haddock, don’t live as long and eat fish that are lower on the food chain, so they have less time to accumulate toxins that build up in the fatty tissue.
When it comes to cooking fish, you can further cut contaminants by trimming skin and fatty tissue. “You don’t want the fish to cook in its own fat because most toxins and mercury are in the fat,” says Alex Jamieson, a certified holistic health counselor and personal chef, who says to skip frying in favor of steaming, broiling, or poaching.
Myth #5: Labels tell you all you need to know about the catch.
Truth: Fish labels can be misleading or missing altogether.
Don’t expect the label on your fish package—if there is one—to indicate how eco-friendly the catch is. As of 2005, the USDA made seafood COOL, meaning it mandated “country-of-origin labeling” so customers would know where their seafood came from and whether it was farm raised or wild caught. But the ruling doesn’t go far enough. The COOL label mandate, according to Fitzgerald, “only applies to supermarkets or large chain stores.”
Another label that can cause confusion is “organic.” Because there’s no such thing as USDA-certified organic seafood, if you do see “organic” seafood, it’s likely from Europe, where standards can vary greatly.
Not sure how to sort through the label lingo? Don’t try, says Rick Moonen, chef and owner of RM Seafood in Las Vegas. “Buying from a source or a store you trust is the way to go,” he says. One label you can trust and that appears on wild-caught varieties more often these days is the Marine Stewardship Council’s seal, a blue oval label that tells you you’re buying from an environmentally responsible fishery.

Blackened Striped Bass With Braised Garlic Greens
1 pound striped bass
4 whole cloves garlic, skin removed
1 teaspoon salt
1 teaspoon cayenne pepper
2 teaspoons paprika
2 teaspoons dried thyme
2 teaspoons dried oregano
2 teaspoons black pepper
3 to 4 tablespoons olive oil
1 to 2 large bunch(es) of spinach greens
