Description:In 1990 the National Marine Mamma1 Laboratory (NMML) was requested to prepare cephalopod identification material for the Resource Assessment and conservation Engineering (RACE) Division ofthe Alaska Fisheries Science Center (AFSC). This reference material was to be used by U.S. fisheries observers to aid in the identification of cephalopods likely to be caught off the Oregon and Washington coasts during the cooperative U.S.-Japan squid jigging surveys in August-septernber 1990. The senior author also gave a demonstration on squid identification using preserved cephalopod specimens to the U.S. observers. A description and catch data of thisU.S.-Japan squid jigging operation are reported by June and Wilkins (1991). At the request of the NMML, whole specimens of each species were collected from jigging stations fished at intervals of 10 minutes of latitude. Another intention of the collection was to demonstrate changes in size and maturity of cephalopods by degree of latitude in the sampling area over lo-day periods. Unfortunately the sample sizes were too small to satisfactoriIy describe changes in size and maturity. Emphasis was also placed on the coltection of specimen material that could be used by biologists examining the diet of rnarine mammals, fish, and birds. This report presents the biological data gathered during examination of these cephalopod specimens.
