Abstract: abstract:For the conservation of seabirds, including albatross and for the effective implementation of the conservation and management measures adopted by WCPFC, the government required fishermen operating in north of 23N and south of 30 S to mandatory using tori lines since 2007. The observer program was ongoing with one of the main purposes of collecting the seabird incidental catch data.According to the data collected, the incidental catch was the highest in the areas between 25 o -40 o N and 165 o W to 165 o E and areas between 25 o -35 o S and 165-180W. In comparison, the incidental catch was low in tropical area. The incidental catch rate (BPUE) in each 10*15 degree grid square varied from 0 to 0.65 per 1000 hooks with the average BPUE of 0.045 per 1000 hooks, with variation of species incidentally caught by areas. Black-footed albatrosses and Laysan albatrosses were the major incidental catch species in the northern area. By using the total effort data estimated from logbooks and the seabird BPUE from observers, the preliminary estimated annual seabird incidental catch was around 1700 from 2002 to 2006.
