Soviet krill fishery in 1977–1992, Part 1. Distribution, fishing effort, interannual situation patterns
Abstract: The data on Soviet krill fishery in i977-1992 are presented. The fishing effort (FE) developed in 1977-1991 was 50086 fishing days in total. According to the pictures presented FE was distributed between subareas 48.1, 48.2 and 48.3. Monthly FE distribution between subareas revealed the

Predation on fish by the southern elephant seal, Mirounga leonina, at King George Island, South Shetland Islands, as reflected by stomach lavage
Abstract: Between november and february of the years 1993/94, 1995/96, 1996/97, 1997/98, 1998/99 and 1999/2000, one hundred and fifty three specimens of southern elephant seals, Mirounga leonina, were stomach lavaged at King George Island in order to analyse their diet. The two major prey types

Herpes virus antibodies in Arctocephalus gazella from Cape Shirreff, Livingston Island, Antarctica
Abstract: This paper describes evidence of antibodies against a virus related with Alphaherpesvirinae sub-family, potentially a phocine herpesvirus (PhHV-1) that affect Antarctic Fur Seals (Arctocephalus gazella) from Cape Shirreff, Livingston Island, Antarctica. Body fluid samples of 54 A.

Seasonal relationships in biological parameters and in spatial distribution in the euphausiid populations sampled during the XIIIth and XVth expedition to the Ross Sea
Abstract: This report summarises the results of krill studies from a large-scale surveys of the Italian Antarctic Oceanographic Cruises conducted in December 1997-January 1998 and January-February 2000. A midwater sampler-trawl (Hamburg Plankton Net) was used to collect zooplankton and fish larvae

A three-frequency method to determine the abundance and the size of two euphausiid species (Euphausia superba and Euphausia crystallorophias)
Abstract: Euphausia superba and Euphausia crystallorophias dominate the biomass and play a key role in the Ross Sea pelagic ecosystem (Marr, 1962; Azzali et al., 1999). To estimate the abundance of each stock it is necessary to discriminate E. superba from E. crystallorophias aggregations and to

Ecosystem modelling for the Antarctic krill fishery
Abstract: Euphausia superba Dana (Antarctic Krill) has been recognized as a key forage species in the Antarctic ecosystem. This species serves as prey for many organisms in the ecosystem and has also been the target of an small industrial fishery since the mid 1970s. New quotas have recently been

Modelling the consequences of Antarctic krill harvesting of Antarctic fur seals
Abstract: In terms of the convention governing the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), management advice for the Antarctic krill (Euphausia superba) fishery should take the needs of the predators of krill into account in order to reduce the risk of

Quantifying habitat use in satellite-tracked pelagic seabirds: application of kernel estimation to albatross locations
Abstract: We develop a new approach to quantifying habitat use within the foraging ranges of satellite-tracked seabirds. We applied kernel estimation techniques to 167 days (3738 locations) of data from black-browed and grey-headed albatrosses Diomedea melanophris and D. chrysostoma during the

Report of the Workshop for the International Coordinated Survey in conjunction with CCAMLR-2000 Survey
Abstract: Vessels from Japan, Republic of Korea, Peru and the USA had participated in the conduct of five acoustic/oceanographic surveys from late December 1999 and to early March 2000 in conjunction with CCAMLR 2000 survey. Time-series acoustic data from the coordinated survey were analyzed.
