Summary
Four parts of the tori-pole were tested for their effectiveness in reducing the incidental catch of albatross in the Japanese southern bluefin tuna (Thunnus maccoyii) longline fishery. Observer data were used to test: 1. bird line material, 2. streamer material, 3. bird line length and 4. pole height above sea surface. The effectiveness of tori-poles in reducing albatross interactions increased with a longer bird line, but there was no difference in the effectiveness between the different bird line materials, type of streamer material or pole height above the sea surface.
