Outline of Final Research Achievements

Human impacts at high seas such as long-line by-catch and trawler discard are concerns for the conservation of seabirds. To study behavioural interactions between albatrosses and fisheries, we deployed GPS and video loggers on Laysan albatrosses (LAAL) at Oahu Island and Black-footed albatrosses (BFAL) at Torishima during their chick rearing periods. LAAL foraged in subtropical, transition and subarctic regions. In subtropical region where tuna long-line fishing was operating, LAAL changed direction of flight-path at 5.4 km and approached to the long-line fishing boats towing or hauling, then followed for 2 hours. During day-time LAAL fed mainly on dead large squids floating in the surface. BFAL foraged in the subtropical basin and followed a bottom-long line fishing boat. BFAL also fed on fragmented squids and dead fish on the surface. This study demonstrates a usefulness of bio-logging techniques for studying fisheries impact on marine mega-fauna.
