Alaska pollock landings are the largest of any single fish species in the U.S, with the average annual Eastern Bering Sea catch between 1977 and 2014 being 1.174 million tons. Alaska pollock catches from U.S. fisheries have been quite consistent at about 1.5 million tons a year, almost all of it from the Bering Sea. Each year's quota is adjusted based on stock assessments conducted by the Alaska Fisheries Science Center. For instance, stock declines in 2008 meant decreased allowable harvests for 2009 and 2010. This decline led some scientists to worry that Alaska pollock could be about to repeat the collapse of the Atlantic cod, which could have negative consequences for the world food supply and the Bering Sea ecosystem. Halibut, salmon, endangered Steller sea lions, fur seals, and humpback whales all eat pollock and rely on healthy populations to sustain themselves. Alaska pollock stocks (and catch levels) subsequently returned to above average in 2011 and remained above average through 2014. However, Greenpeace has long been critical of Alaska pollock management, placing the fish on its "red list" of species due to damage of the seabed from trawling.
