Losses of seabirds in gill nets in the North Pacific

January 1, 1993

Existing knowledge on high-seas and coastal gillnet fisheries known to kill seabirds in the North Pacific is summarized. Recent estimates suggest that high-seas gillnet fisheries may have taken more than 500,000 seabirds in 1990. The majority of birds taken in those fisheries were Sooty Puffinus griseus or Short-tailed P. tenuirostris shearwaters. A recent analysis of impacts of those fisheries suggests that both shearwater populations may be declining slightly, although overall populations remain large. Impacts on seabirds of gillnet fishing in coastal waters are poorly known, except in California. Incidental mortality of seabirds in coastal gillnet fisheries may be adding additional stress to populations already compromised by habitat destruction and oil spills. Local populations of Marbled Murrelets Brachyramphus marmoratus, Common Murres Uria aalge, and Japanese Murrelets Synthliboramphus wumizusume may be particularly vulnerable to coastal gillnet fisheries. United National General Assembly Resolution 44/225 called for a moratorium on high-seas gillnet fishing by 30 June 1992. Japan has complied and Korea and Taiwan will comply with the moratorium.
