Results of E.L. Holmberg 1995 fish survey in Subarea 48.3
Abstract: The survey comprised 48 bottom trawl hauls taken in subarea 48.3. About 80% of the hauls were intended as replicates of the position of hauls in the 1994 survey, allowing site by site comparison between both cruises. Of these, 20 hauls were located at less than 0.5 miles and 11 between 0

Albatross mortality and associated bait loss in the Japanese longline fishery in the Southern Ocean
Abstract: A conservative calculation of the number of albatrosses killed annually on Japanese longlines in southern oceans in 44 000. The actual figure could be double and is sufficiently high to substantiate claims that serious declines in albatross populations are due to this fishing activity.

Population dynamics of the wandering albatross (Diomedea exulans) on Macquarie Island and the effects of mortality from longline fishing
Abstract: The estimated breeding population of wandering albatrosses on Macquarie Island increased from 17 in 1956 to a maximum of 97 in 1966, and then declined at an average rate of 8.1% per year. Mark-recapture analysis shows that the population is not closed (i.e., subject to immigration and

Use of a population model to assess the impact of longline fishing on wandering albatross populations
Abstract: An age-structured model of a wandering albatross Diomedea exulans population is developed to simulate population trends over time, using demographic parameters from the population at Possession Island Crozets, during 1968 to 1986. The simulation results portray a population decreasing at

Reduced bait loss and bycatch of seabirds in longlining by using a seabird scarer
Abstract: Although longlining is regarded as a highly conservation oriented method of fishing, bycatch of seabirds on longlines is a problem in certain seasons and areas. Birds feeding on the bait during setting of the gear might cause considerable bait loss and occasional hooking of birds might

Report on a tuna long-lining fishing voyage aboard Southern Venture to observe seabird by-catch problems
Abstract: Incidental captures of seabirds, and the behaviour of seabirds around the fishing gear as it was deployed, were observed during 8-days' fishing of a New Zealand-owned tuna long-liner. From 11,200 hooks set 6 seabirds were hooked and recovered: 5 Wandering Albatross Diomedea exulans

Changes in population size of large Procellariiformes breeding in the French sub-Antarctic islands: potential influence of southern fisheries and particularly long lining
Abstract: Studies carried out over the past three decades in the French austral territories indicate that most albatross and giant petrel populations have markedly declined. Demographic studies indicate that these declines are mainly the result of increased adult mortality. This high rate of
