1. Selectivity of standard polish commercial trawl codends on Antarctic fishing grounds

   difficult matter will be preparing a codend with proper selectivity properties for South Georgia icefish ... Abstract:  steelon codends used in commercial fishery, with a nominal mesh size A = 80 mm and A ... = 100 mm, made of double twines with a thickness of 4.2 mm. The studies covered 6 major fish species. 1 ... . It appears from the study that Antarctic icefish and bumphead notothenia are subject to selection ...

5. Examination of the CCAMLR toothfish GLM

   nationalities, coupled with the existence of the experimental fishery in 1994, lead us to suggest that future ... CPUE in Subarea 48.3 are investigated. Problems with crossover between the essentially summer fishery ... analyses should be restricted to GLMs based on winter data alone. Unfortunately, this does result in there ...

6. Variability of krill stock composition and distribution in the vicinity of Elephant Island during AMLR investigations 1988-1992

   distributional patterns during each year indicate that the older age classes were associated with oceanic/Drake ... recruitment from the 1989/90 and 1990/91 year classes. Year class success may be related to the abundance of ... Passage waters while younger classes were associated with water masses to the south. Between-year ...
