Description

The effectiveness of albatross deterrent techniques was examined during line setting operations in the Hawaii-based longline fishery for swordfish (Xiphias gladius). Methods tested were bird scaring streamer lines, weights added to baits, and camouflaging bait with food coloring. Observations were made on ca. 66 baited branch lines deployed on 96 occasions. Baits dyed blue and baits with added weight both reduced the number of contacts between baits and Black-footed (Phoebastria nigripes) and Laysan (P. immutabilis) Albatrosses by about 90%. Streamer lines reduced contacts between baits and albatrosses by about 70%.
