Description: "The purpose of this report is to present a re-analysis of the marine mammal incidental take data from 1998 to 2001 (Perez 2003) and add the previously unanalyzed bycatch data from 2002 to 2004, based on the new 2004 [List of Fisheries] classifications of groundfish fisheries in Alaska defined by the intended target groundfish species caught by trawl, longline, and pot fishing gear."--P. 2.
