Species has a combination of problems such as overfishing, high bycatch, and poor management.
Cod, Atlantic – U.S. (except Georges Bank handline fishery)

Atlantic Cod are a species of groundfish that can live more than 20 years. They are found throughout the North Atlantic, and have been heavily fished for centuries driving some populations to historic low levels.

In the U.S. Gulf of Maine and Georges Bank, the abundance of Atlantic Cod is low. While management efforts in the U.S. have improved in recent years, recovery is still expected to be slow for Atlantic Cod populations.

Fishermen use a variety of fishing gears to catch Atlantic Cod including bottom trawls, gillnets, longlines and handlines. In addition to catching Atlantic Cod, most of the fisheries also catch other depleted species, like haddock, and the gillnet fisheries often catch marine mammals. Because of these concerns, most U.S. Atlantic Cod is rated red. Atlantic Cod caught in the more selective Georges Bank handline fishery is rated yellow.
