NRDC SAVING OUR FISHERIES

摘要

Why is bycatch such a threat to our oceans?rnBycatch is a principal cause of overfishing and can harm marine ecosystems. In the New England groundfish fishery, which includes cod, haddock, and various flounder species, and the mid-Atlantic squid fishery, it is estimated that more fish-tens of thousands of metric tons each year-are discarded at sea than are landed and sold. Some species are seriously depleted by bycatch, like the iconic Georges Bank cod, which is at only 15 percent of healthy levels and is not projected to be rebuilt until 2055. Bycatch has also decimated populations of key forage fish in the region, such as butterfish and river herring.
