It may seem like the ocean is just a bottomless pit of fish sticks and sushi, but the reality is that our supply of seafood is finite. Through rampant overfishing and just generally treating the ocean like a cheap buffet, we've depleted the populations and ruined the habitats of some truly delicious fish.
To find out which species are in the most danger, we spoke with Reid Bogert, sustainability coordinator at the Shedd Aquarium in Chicago, who in addition to scaring us skate (zing!), offered some tasty alternatives. Read on to learn more about which salmon is safe, which seafood certifications to look for, and why grouper are basically screwed.
Reid says: "The stocks on the East Coast where these are native have just not been managed as well as in Alaska and California, where the salmon are plentiful and healthy."
Another option: "Pacific salmon is only available a few months of the year, but Arctic char is in the same family and is available year-round. It has a similar beautiful pink meat and flavor profile that's rich in fatty acids. They don't require much fish feed, so they have a smaller footprint."
Reid says: "Swordfish is a popular dish all over the world that has been overfished using a certain technique called longline fishing. It puts other wildlife at risk because you can have miles of baited line trailing a boat. All of that fishing line makes other sea life vulnerable. Sea turtles, sharks, even albatross can grab a line and become what's called bycatch."
Another option: "Look for swordfish with a third-party certification from a non-profit, like Marine Stewardship Certification or Best Aquaculture Practices. But you could also go with mahi mahi. It's a smaller fish, which tends to be a bit healthier and reproduces quicker. The meat is similar to swordfish. It's dense and has a wonderfully natural citrus flavor."
Wild-caught sea scallops
Reid says: "In the past you always had to take a big dredge and dig into the bottom of the ocean to get the scallops out. That was disrupting the habitat and making it so the shellfish couldn't reproduce at an acceptable rate. Now you have divers out there collecting them by hand, but it's just a much more involved process."
Another option: "People are often surprised that farmed shellfish are one of the most sustainable seafood types you can find on the market. Scallops, clams, mussels, oysters, anything with a shell can be farmed and harvested sustainably."
Bluefin or bigeye tuna
Reid: "It takes them longer to reach maturity than most fish, and what that really comes down to is the nature of how they reproduce. They also swim in schools, which makes them more vulnerable to very large nets that can catch a lot of fish at once. And there's such a high market demand because it's such a great-tasting fish."
Another option: "Skipjack tuna reproduces more often, grows quickly, and is smaller so there's less of a concern about mercury."

Reid says: "We import something like 90% of our shrimp. Some of the issues are just the way those fisheries are managed. They're often in sensitive habitats that don't regrow after they've been impacted by a shrimp farm, and they'll often use antibiotics and pesticides to manage those fisheries, so you're dealing with chemicals in the water."
Another option: "Here in the Midwest, there's a growing movement of sustainable aquaculture, so there are several farms doing things like tilapia or shrimp that are based on land or produced in systems that are recycling the water, using fewer chemicals, and ensuring the health of those animals and also people on the table side."
Reid says: "This is a deep-water fish whose population basically collapsed in the '90s and never really recovered."
Another option: "There's a fish called hake which tastes very similar. It breaks off in big chunks, which is a signature feature of cod. Or a softer whitefish like catfish, which believe it or not is very sustainable and amounts to nearly two-thirds of the aquaculture in the U.S."
