  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 ... emigration). The decline is correlated with the onset of large-scale fishing for tuna in the southern ... hemisphere using longlines. The effect of longline mortality on the population dynamics of the wandering ...

  4. Spatial overlap of krill-dependent predators and krill fishery catches and a proposal for subdivision of catch limits in Subarea 48.1

    Abstract:  Progressing from Stage 1 to Stage 2 of a feedback management strategy requires a better ... understanding of spatial overlap between predators and fishing activity. We provide estimates of the spatial ... in Subarea 48.1. In general, overlap of summer and winter foraging habitats with krill catches in ... might affect the distribution of fishing effort.  A comparison of CEMP parameters from two years with ...
