Workshop on Marine Mammal-Fisheries Interactions in the Northeastern Pacific Held at Seattle, Washington on 19-20 December 1977

摘要

The workshop reviewed what is currently known of marine mammal/fisheries conflicts in Alaska, British Columbia, California, Hawaii, and Oregon (except sea otter and tuna/porpoise problems). Set gear types (such as longlines and gill nets) are more troubled by marine mammals (principally harbor seals and Steller or California sea lions) taking the catch and damaging gear and moving types of gear (such as trolled hooks or drag nets). There are increased conflicts with sport fisheries due to redistribution since the MMPA of 1972. The participants determined what data and methods were needed to make future management decisions and recommended that research be initiated on the conflicts of the Columbia River to develop these types of data.
