| Abstract | tWe used a combination of seabird data (both fishery-dependent and fishery-independent) and fishing-effort data to evaluate the relative fisheries risk of five west coast groundfish fisheries and oneshrimp fishery to black-footed (Phoebastria nigripes), short-tailed (P. albatrus) and Laysan albatrosses(P. immutabilis). To assess risk, an overlap index was derived as the product of total fishing effort andat-sea survey density of black-footed albatross. This index was used as the primary tool to estimate over-lap with the endangered, relatively rare short-tailed albatross, which show similar habitat utilizationfrom satellite telemetry tracks. Telemetry data indicate Laysan albatross primarily occur offshore beyondobserved fishing effort. Black-footed and short-tailed albatross-fishery overlap was highest at the shelf-break (201–1000 m) north of 36◦N. Overlap and reported albatross mortality indicate that the sablefish(Anoplopoma fimbria) longline and Pacific hake (Merluccius productus) catcher-processor fisheries posethe greatest risk to these species; the near-shore rockfish (Seabastes spp.) longline, pink shrimp (Pandalusjordani) trawl, California halibut (Paralichthys californicus) trawl, and non-hake groundfish trawl fisheriespose relatively little risk. Implementing proven seabird bycatch-reduction measures will likely minimizealbatross mortality in the highest-risk fishery, sablefish longline. |
