1. 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

2. 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

3. 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

4. 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

5. 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

6. 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

7. Assessment of toothfish in Subarea 48.3, 2006

   Abstract:  1. As requested by SAM-2006, we provide a reference assessment for toothfish in Subarea 48.3. We provide sensitivity runs that include revised maturity and catch weighted proportion at length data. We additionally provide a sensitivity run which examines uncertainty in IUU catches from

8. Estimates of natural and fishing mortality from toothfish mark–recapture and catch-at-age data at South Georgia

   Abstract:  This paper presents new results and estimation bias analyses for a Bayesian mark-recapture model, applied to the South Georgia toothfish tagging data. The updated model incorporates the data from all the analysed cohorts in the estimation routine, and we examine the potential estimation

9. A proposal methodology to assess the Patagonian toothfish stock abundance at CCAMLR Subarea 48.3 using ASPM

   Abstract:  The ASPM is an integrated modeling technique used in stock assessment of different D. eleginoides fisheries (Prince Edward Islands and Patagonian Shelf) and allows fitting to many different information sources, such as catch and age and size data from fishing fleet, surveys and others
