• In 2004 four large groups of federally managed fisheries in Alaskan waters were separated into 25 fisheries based on geographic location, target species and gear type.  This fishery was included in the larger group of “Bering Sea, Aleutian Islands groundfish trawl” fishery prior to 2004, and in 2004 was broken out as the “Bering Sea, Aleutian Islands rockfish trawl” fishery.  It was placed in Category III at that time as no specific information on marine mammal takes were attributed to that fishery.
