1. 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

2. 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

3. 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

4. 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

5. 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

6. Interactions between longline vessels and seabirds in Kerguelen waters and a method to reduce seabird mortality

   Abstract:  In recent years, a new longline fishery for the fish Dissostichus eleginoides has developped in the vicinity of South Georgia and Kerguelen islands, two internationally important breeding areas for procellariiform birds. Attractiveness of this fishery for seabirds, together with the

7. Entanglements and incidental mortality of birds and seals - summary of reports to CCAMLR, 1985 to 1993

   Abstract:  This paper summarises the incidence of entanglements and incidental mortality of birds and seals reported by CCAMLR Members for the CCAMLR Convention Area and adjacent waters from 1985 onwards. A bibliography on entanglement, incidental mortality and effects of marine debris on seabirds
