Overview and update of Australia’s scientific tagging program in the Patagonian toothfish (Dissostichus eleginoides) fishery in the vicinity of Heard and McDonald Islands (Division 58.5.2)
understanding growth rates of toothfish, small and large scale movements, stock structure and local abundance ... . This paper serves as an overview of the tagging dataset, and an update to previous summary papers ... . Tagging effort and recaptures are very concentrated in a relatively small area of this species’ habitat in ... this Division. Furthermore, as toothfish appear to have complex patterns of movement in space and time ...

Some aspects of the relation between Antarctic krill abundance and CPUE measures in the Japanese krill fishery. (Component of SC-CAMLR-VI/BG/4)
Abstract: The history of the Japanese krill fishery is reviewed briefly. Important aspects of the ... time data may be needed to assess the density of swarms in a concentration, but may be difficult to ... record in practice, and a number of other factors may complicate any analysis. The possibility of ... indexing the extent of the krill distribution through routine oceanographic monitoring merits attention. A ...

Review of Dissostichus spp. fishery in the adjacent seas of three Antarctic sectors in 2003–2010
of the Antarctic toothfish is commercially viable not only for countries which are close to the ... the Pacific and Indian sectors of the Antarctic. According to lack of data on the Antarctic toothfish ... estimation of toothfish stock and TAC values in all high-latitude Antarctic seas is necessary. From data ... available we suggest that factual stock values of the Antarctic toothfish are considerably underestimated in ...

Abundance, size and maturity of krill (Euphausia superba) in the krill fishing ground of Subarea 48.1 during 1990/91 austral summer
north of the South Shetland Islands from 18 January to 3 February 1991. Distinct offshore-inshore ... heterogeneities in abundance and maturity of krill were observed. The survey region was divided into four zones ... ; oceanic, slope frontal, neritic and nearshore zones. The mean density of krill was low in the oceanic zone ... (95% confidence limit), of which 1.22 ± 0.42 million t was concentrated in the fishing grounds (" ...
