Observations on High-Seas Squid Gill-Net Fisheries, North Pacific Ocean, 1985

摘要

The National Marine Fisheries Service (NMFS), in cooperation with the U.S. Coast Guard (USCG), conducted observations of the high-seas squid gill-net fisheries in the North Pacific Ocean for 36 days, from 15 August to 19 September 1985. USCG personnel boarded 15 gill-net vessels, and NMFS scientists observed five deployments and 11 retrievals of gill nets. The squid boats varied in size, as did their gill nets which were 7-30 nautical miles long. A single day's catch ranged from 871 to 8,256 squid and 5 to 530 tuna. Average catch per nautical mile for squid, tuna, and pomfert was 127.0, 9.4, and 78.9, respectively. In addition to catch data, information on the vessels, fishing techniques, equipment, and schedules was also collected.
