Data on incidental mortality of seabirds and marine mammals associated with longline fishing around the Falkland Islands between August 1996 and May 1997 are briefly summarised. For seabirds, the overall average rate of incidental mortality was 0.34 birds per 1000 hooks; excluding a single set when 87 birds were caught, the average was 0.05 birds per 1000 hooks. Black-browed albatrosses comprised 90% of birds caught.
Abstract:
According to the results of the long-term studies (1967–1991) in expeditions to the sub-Antarctic and Antarctic waters of the Indian Sector of the Southern Ocean, distribution areas of the Patagonian and Antarctic toothfish are clearly cut. It was concluded that the areas of these toothfish species were not overlapped in the area under review.
Abstract:
Available in YugNIRO data concerning distribution of Antarctic toothfish juveniles in the Indian Sector of the Antarctic are used in the paper. In the summer period of the southern hemisphere (January–March) juveniles of D. mawsoni with size from 4–9 to 30–75 cm were regularly registered in catches of bottom and pelagic midwater trawls in all the studied continental seas from 12 to 144°E.

Abstract:
Patagonian toothfish (Dissostichus eleginoides) was found in catches of 25 trawls in the offshore area of South Georgia, and in catches of 13 trawls in the Shag Rocks Shelf. It was caught at all strata depths, but the most abundant catches were at 260-320 m depth. On the whole, catches of Patagonian toothfish consisted of juveniles 21–37 cm in length, immature fishes 41–78 cm in length and mature fishes 80–88 cm in length. Nevertheless, there were differences in the length range and the modal lengths of fish taken from different parts of the South Georgia shelf and the Shag Rocks shelf.
