  3. 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 ...

    combination of concurrent at sea (predator observations, net hauls and multi-frequency acoustics), and land ... -based (animal tracking and diet analysis) techniques, we examined variability in the foraging ecology of ... these sympatric top predators during the austral summer and autumn of 2004. Krill availability derived ... occurred in 80% of fur seal diet samples, with fish remains in 37% of samples. Penguin diets contained the ...
