Longfin Squid are found along the coast from Georges Bank to Cape Hatteras, rising to the surface at night to feed and spending their days along the sea floor. Squid grow rapidly and lead short lives of 9 months. Longfin squid may exceed a foot in length but usually are well under a foot long when caught. Squid are predatory and consume a variety of crustaceans and smaller fish. The longfin squid population is healthy, and harvest rates are sustainable. The longfin squid fishery is managed using several methods including an annual catch quota, a minimum codend mesh size for trawl nets, and a limited access permit program. Squid are an excellent source of selenium, riboflavin, and vitamin B12. The majority of the world's catch of longfin squid comes from the waters of the northwest Atlantic Ocean. The United States is the primary source for this species.
