Entanglement of Antarctic fur seals Arctocephalus gazella in man-made debris at Bird Island, South Georgia during the 1993 winter and 1993/94 pup-rearing season
the fourth consecutive winter and sixth consecutive summer at Bird Island, South Georgia. In the 1993 ... winter the number of entangled seals was only 39% of the record 1992 total, but still 5 times the numbers ... in 1990 and 1991. Nearly all animals were juveniles, half with severe injuries and the proportion of ... females (40%) was the highest yet reported. The proportion of animals entangled in packaging bands was the ...

Further development of coarse- and medium-scale spatially explicit population dynamics operating models for Antarctic toothfish in the Ross Sea region
operating models for Antarctic toothfish in the Ross Sea. The operating models consider both a coarse-scale ... and medium-scale spatial resolution and consider scenarios where abundance can be present over the ... entire Ross Sea region or restricted to areas where the fishery has operated. The models are implemented ... in the generalised Bayesian population dynamics model, the Spatial Population Model (SPM). The SPM ...
