GOA Trawl Sweeps modification Discussion Paper
In October 2010, the Council initiated a trailing amendment to require trawl sweep modifications on nonpelagic trawl vessels fishing in the Central Gulf of Alaska (GOA). The action was initiated in conjunction with final action on the GOA Tanner crab bycatch measures. A similar gear modification, wh...
