4. Preliminary results of the Polish commercial krill fishery in the Antarctic during 1990/91 season

   Abstract:  Four Polish commercial trawlers participated in the krill fishery in 1990/91 season on the fishing grounds in statistical Sub-areas 48.2 and 48.3. In total 9 333.7 tonnes of krill were harvested. As the fishery data were not fully analysed yet no clear trends in catch-per-unit-effort for

5. Chilean krill fishery: analysis of the 1991 season

   Abstract:  This paper summarized the chilean catch data for 1991. Especial emphasis is given to the analysis of haul-by-haul data and its use in understanding small scale spatial distribution of fishing grounds. The results show that the krill fishery in subarea 48.1 is particularly intense near

7. TEMPORAL CLARIFICATION OF THE TRANSITION FROM BLUE PHASE FINGERLING TO EARLY JUVENILE BROWN PHASE IN NOTOTHENIA ROSSII FROM THE SOUTH SHETLAND ISLANDS

   Abstract:  Scales and whole otoliths were read for age determination of early stages of Notothenia rossii caught in Potter Cove, South Shetland Islands, in summer of years 2003-2006 and 2008. The sample was composed by blue phase fingerlings of 7-7.6 cm (TL) and age group 0 year and demersal young

8. PRELIMINARY ASSESSMENT OF MACKEREL ICEFISH, CHAMPSOCEPHALUS GUNNARI, IN THE VICINITY OF HEARD ISLAND AND MCDONALD ISLANDS (DIVISION 58.5.2), BASED ON A SURVEY IN APRIL 2009, USING THE GENERALISED YIELD MODEL

   Abstract:  A survey of mackerel icefish, Champsocephalus gunnari, was undertaken in Division 58.5.2 in the vicinity of Heard Island in April 2009 to provide the information for an assessment of short-term annual yield in the 2009/2010 CCAMLR season. This paper provides a preliminary assessment of

9. REPORT ON A RANDOM STRATIFIED TRAWL SURVEY TO ESTIMATE DISTRIBUTION AND ABUNDANCE OF DISSOSTICHUS ELEGINOIDES AND CHAMPSOCEPHALUS GUNNARI IN THE HEARD ISLAND REGION (DIVISION 58.5.2) FOR 2008 AND 2009

   Abstract:  The random stratified trawl surveys (RSTS) for 2008 and 2009 were successfully completed on the RV Southern Champion, continuing the series that commenced in 1997. Catches in 2008 were generally reduced from the previous year’s survey, with the catch of toothfish being one third of that
