On possible impact of new continuous krill fishing technology on juvenile fish and larvae
Abstract: The new continuous krill fishing system uses both a small-meshed midwater trawl and a powerful pumping system for continuous pumping the catch out of the trawl bag. It was discussed the potential threats of new technology to Antarctic marine ecosystem. It was shown that application of

Mercury concentrations in Patagonian toothfish, Dissostichus eleginoides Smitt 1898, among three distinct ocean basins
Abstract: Patagonian toothfish, Dissostichus eleginoides, collections (n-186) from three ocean basins were analysed for Hg concentration and comparisons were made by gender, total length (TL), wet weight (WW), and basin. There was no difference between TL-WW relationships by gender within any

Information on the status of fjord Notothenia rossii, Gobionotothen gibberifrons and Notothenia coriiceps in the lower South Shetland Islands derived from a long-term monitoring program (1983–2006) at Potter Cover
Abstract: The long term monitoring program of demersal fish at inshore sites of the South Shetland Islands has continued at Potter Cove from 2000 to 2006, covering a continuous sampling period of twenty four years, and at Harmony Cove, Nelson Island, in the austral summers from 2001 to 2003. The

Species profile for Antarctic toothfish (Dissostichus mawsoni)
Abstract: A toothfish species profile, covering aspects of the biology, fisheries and stock assessment of both toothfish species was completed by Everson (2002). Aspects of the biology of D. mawsoni were summarised by Hanchet et al. (2003), whilst more recent research has been reported in

Stomach contents of sub-adult Antarctic toothfish (Dissostichus mawsoni) from the western Ross Sea, Antarctica
Abstract: The stomach contents of 190 sub-adult (51-100 cm TL) Antarctic toothfish (Dissostichus mawsoni) captured by bottom longline in the western Ross Sea were analysed. Fish were sampled during the 2005 fishing (Dec 2004 to Jun 2005) season and caught in 398-1678 m depths. Sub-adult D. mawsoni

A characterisation of the toothfish fishery in Subareas 88.1 and 88.2 from 1997/98 to 2005/06
Abstract: The exploratory fishery for Antarctic toothfish (D. mawsoni) has been operating for nine years in Subarea 88.1 and for five years in Subarea 88.2 with a large amount of data collected on toothfish and the associated bycatch. All SSRUs in the two subareas except for 881D and 882C have now

Towards a seabird mortality risk assessment: distribution of seabirds in the WCPFC Convention Area and potential overlap with fisheries
Abstract: This paper reviews the distribution of seabird species with the WCPFC Area. From a review of the distributions of 99 species of albatross and petrel, 16 species of albatross and 60 species of petrel occur within the area of the WCPFC, and are potentially vulnerable to fisheries bycatch.

Some thoughts on the CCAMLR risk assessment for seabird–fishery interactions
Abstract: The CCAMLR system for assessing risk of fisheries mortalities to seabirds has been applied for 10 years and helps to define mitigation and monitoring requirements for fisheries within the waters of the CCAMLR convention area. Annual review of the information by used CCAMLR Working Group

Estimating fishing gear selectivity for trawlers using length-frequency data from concurrent commercial trawl and longline fishing for Patagonian toothfish in Division 58.5.2 and the ratio of their hazard functions
Abstract: The upper-arm of the length-dependent fishing selectivity function for trawlers fishing for Patagonian toothfish around Heard Island (Division 58.5.2) was modelled as the exponential of a quadratic function in length. This function was calibrated using random length frequency (LF) data

Assessment models for Antarctic toothfish (Dissostichus mawsoni) in SSRU 882E including data from the 2005/06 season
Abstract: We provide an update of the Bayesian sex and age structured population stock assessment model for Antarctic toothfish (Dissostichus mawsoni) in the SSRU 88.2E, using revised catch, CPUE, catch-at-age and tag-recapture data from New Zealand and all vessels. The updated reference case
