Seafood Sold as ‘Wild’ Often Isn’t

Wild salmon and other seafood is generally believed to be a healthier choice, because some varieties contain lower levels of industrial toxins than farmed fish. But when you buy seafood sold as “wild” at your local grocer, you may not be getting what you pay for.
That’s the conclusion of a new study by the University of California-Santa Barbara that found fish sold as “wild” is often produced through a combination of techniques that include the use of fish hatcheries. In fact, much as 40 percent of Alaskan salmon labeled "all wild, never farmed” actually originated in fish hatcheries, according to the study, published in the journal Marine Policy.
"Farming fish and shellfish is generally a different way to produce seafood than fishing," said lead researcher Dane Klinger. "While fisheries traditionally interact with their target population only at the time of capture, aquaculture, in its 'purest' state, controls the entire lifecycle of the organism, from egg to harvest. However, many common types of seafood are produced using techniques from both fisheries and aquaculture."
The research team, from UC Santa Barbara's National Center for Ecological Analysis and Synthesis, recommends the use of a new label to flag seafood produced and harvested through a combination of techniques. The group has called on national and international organizations and agencies to use the term "hybrid," when applicable.
"We need to start collecting more accurate data on how seafood is really produced in today's world, and a first step will be through replacing the old farmed-fished dichotomy with a farmed-fished-hybrid classification scheme,” said researcher Mary Turnipseed.
For the study, researchers examined several popular seafood products harvested using a combination of techniques. In addition to noting hatcheries stock Pacific salmon in Alaskan fisheries, they said hatcheries also stock scallops in New Zealand waters and eastern oysters in the Chesapeake Bay. In addition, American lobsters are fed by bait placed in traps until they reach legal catch size and Bluefin tuna farms obtain their stock by fishing.
Health experts recommend fish as part of a healthy diet, but note that certain varieties contain high levels of industrial chemicals that can be harmful. Some farmed varieties have higher concentrations of toxins.
Salmon is rich in omega-3 polyunsaturated fat and is a good source of protein, for instance. But studies have found that some salmon species and other fish are contaminated with methylmercury, dioxins and polychlorinated biphenyls (PCBs). A report from the Environmental Working Group showed that farmed salmon in the U.S. has the highest levels of PCBs – a finding echoed by a recent study in the journal Science that found farmed Atlantic salmon had higher levels of PCBs and other toxics than wild Pacific salmon.
