2. Seabird mortality in the Japanese tuna longline fishery around Australia, 1988–1995

   Abstract:  Large numbers of seabirds are killed each year within the Australian Fishing Zone (AFZ ... ) by Japanese longline vessels targeting tuna. In recent years the estimated rate of seabird bycatch in ... the AFZ has been in the order of 0.15 birds 1000 hooks, translating to mortalities of 1000-3500 birds ... southern Australia. Uncertainties in the observed catch rates prevent confident assessment of trends, but ...
