A Seafood Watch assessment of the U.S. shrimp fishery in the Gulf of Mexico and South Atlantic released last October reaffirms that the U.S fleet is a global leader in addressing one of the most critical conservation threats facing sea turtles: bycatch of endangered and threatened turtles in shrimp trawl nets.
The report concludes that most wild-caught U.S. shrimp remains a Good Alternative—except for shrimp from Louisiana or shrimp caught in nets that haven’t been modified to protect sea turtles and other species caught accidentally by shrimp boats.
Alone among Gulf of Mexico and South Atlantic states, Louisiana prohibits enforcement of federal requirements to use Turtle Excluder Devices (TEDs), which have proved effective in reducing sea-turtle deaths and allowing their populations to begin a slow recovery.
Under a 1987 state law, Louisiana officials are forbidden from enforcing TED requirements in state waters, where most shrimp fishing occurs.
“Even when conscientious Louisiana fishermen voluntarily comply with regulations that protect sea turtles, the state’s mandate not to enforce this essential measure creates a critical conservation concern and an ‘Avoid’ recommendation for all shrimp caught in Louisiana,” said Margaret Spring, vice president of conservation and science for the Monterey Bay Aquarium. Spring played a key role in crafting the Magnuson-Stevens Fishery Conservation Act, whose provisions are driving the recovery of fisheries in U.S. waters.
“In all other shrimping states—from the Carolinas to Texas—use of Turtle Excluder Devices has been effective in reducing impacts on sea turtles,” Spring said. “We applaud the strong federal and state fisheries management policies that require TEDs, and the conscientious shrimp fishermen who are using TEDs. They are leading the way in sea-turtle recovery.”
In addition to using TEDs to protect sea turtles, Seafood Watch director Jennifer Dianto Kemmerly said that most U.S. shrimp boats use bycatch-reduction devices that play a vital role in the recovery of commercially important fish species, like red snapper, that would otherwise be accidentally killed in shrimp trawling gear.
Bycatch-reduction devices and TEDs are not required on the skimmer trawls used by some shrimp boats. Shrimp caught using skimmer trawls—a small fraction of total U.S. shrimp landings—also remains on the Seafood Watch “Avoid” list.
A proposed federal rule to require TEDs in skimmer trawls was withdrawn in February 2013, and other mitigation measures provide too little protection for sea turtles or are poorly accepted by skimmer-trawl fleets.
Seafood Watch regularly assesses wild-caught and farmed seafood based on peer-reviewed science reports published on the Monterey Bay Aquarium website. The reports incorporate input from fishing interests, academic experts and federal and state fishery scientists and managers—including information from NOAA’s Fish Watch.
