1. Geographical differences in the condition, reproductive development, sex ratio, and length distribution of Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea, Antarctica (CCAMLR Statistical Subarea 88.1)

   Abstract:  A number of morphological and reproductive measurements made seasonally on Antarctic toothfish Dissostichus mawsoni from mid-December to early April during the 2000-01 to 2004-05 fishing seasons aboard the autoliner San Aotea II have been analysed. Results of this study indicate

2. Mitigation trials and recommendations to reduce seabird mortality in the pelagic icefish (Champsocephalus gunnari) fishery (Subarea 48.3)

   Abstract:  Trials were conducted during the 2004/5 mackerel icefish (Champsocephalus gunnari) season in sub-area 48.3, to quantify seabird interaction with fishing operations, to trial different mitigation methods in an attempt to reduce seabird mortality caused by entanglement with the net and to

3. A method for inferring movement rates of fish from mark–recapture data

   Abstract:  This paper presents methods to infer the rate of movement of fish that are marked, released, and subsequently captured. The information that is available is the location and date of the release and the recapture. In addition, the intensity of fishing effort (i.e. sampling) by location

4. Seabird abundance and by-catch on Brazilian longline fishing fleet

   Abstract:  Southern Brazil is an important foraging ground for several albatross and petrel species during breeding and non-breeding seasons. We present information on seabirds attending longline fishing vessels on Brazilian Exclusive Economic Zone and international waters of the Southwestern

5. By-catch in the Australian fisheries in Division 58.5.2

   Abstract:  This paper presents bycatch information for the Australian fisheries in Divisions 58.5.2 for the 2003/2004 and 2004/2005 seasons. Bycatch in the trawl fisheries was low, generally less than 1% of the total catch (target plus bycatch). Higher percentage bycatch rates occurred in trawling

6. Evaluating methods to assess yield of Patagonian toothfish (Dissostichus eleginoides) in CCAMLR Division 58.5.2

   Abstract:  This paper describes aspects of the Management Strategy Evaluation (MSE) being developed to evaluate possible management strategies for the Patagonian toothfish fishery in Division 58.5.2. As requested by the Subgroup on Assessment Methods, we elaborate the plausible operating models

7. Biological and fishery information for skates in Division 58.5.2

   Abstract:  This paper presents biological and fishery information available for skates from Division 58.5.2. Estimates of growth calculated from trawl-tagged, recaptured B. eatonii were 15 mm per year in total length and wing span, and 0.15kg per year in mass, indicating that this species is very

8. Two species of toothfish in two basic longline fisheries regions – Patagonian toothfish in Subarea 48.3 (South Atlantic) and Antarctic toothfish in Subareas 88.1 and 88.2 (South Pacific)

   Abstract:  Now after more then 30 years studies a most valuable commercial (target) species in the CCAMLR Area two species of genus Dissostichus. They have wide circumpolar distribution but difference in latitudes of the boundaries area distribution Patagonian and Antarctic toothfish. Our

10. Exploring the ASPM as an alternative method to estimate the Patagonian toothfish biomass at CCAMLR Subarea 48.3

    Abstract:  ASPM have been proposed and applied for Patagonian toothfish stock assessment at CCAMLR Subarea 48.3. Last results obtained from this model, discussed at WG-FSA (2004), do not show acceptable fit with standardized CPUE series and observed length proportions in the catches. In this paper,
