Tke^ VoKaevs of geKevaiizAtioKs lough trawl fisheries account for more bycatch than "other gear types, bycatch also occurs with gillnets, longlines, purse seines, trolls, pots, dredges, sportfishing ^gckle, and all other gear. Generalizing about any one â ieartype is dangerous, however, because of great Bariability in gear conformation, fishing practices, geographic area, season, time of day, crew expertise, and other factors. One of the most highly publicized bycatch controversies did not involve trawling at all, but concerned the high- seas driftnet fisheries for salmon and squid. FAO notes that bycatch rates and types differed dramatically among the few nations using this gear, with Japanese driftnets having a much greater bycatch of salmon, marine mammals, sea birds, and turtles than did the more numerous Korean and Taiwanese nets. But they were all perceived as jeopardizing the ocean ecosystem, and all use of these huge nets has now been banned by the United Nations. Effective enforcement is one key to effective bycatch regulation. State and federal scientists onboard research vessels provide information on discarded catch.
