1. Is our attempt to estimate biomass of Antarctic fish from a multi-species survey appropriate for all targeted species? Notothenia rossii in the Atlantic Ocean sector – revisited

   Abstract:  Notothenia rossii was the first target species of the fishery in the Southern Ocean ... . The species has been heavily fished at the beginning of the 1970’s. The closure of the fishery for ... this species was one of the first conservation measures CCAMLR adopted in 1985. Fish biomass within a ...

2. Comparative studies on the biological and acoustical properties of krill aggregations (Euphausia superba Dana) samples during the XIII Italian Expedition to the Ross Sea (December 1997–January 1998)

   (December-January 1997-98), for biological validation of hydroacoustic recordings, 35 net samplings were ... carried out. For all hauls both parameters: biological (length AT, sex and maturity stage of the gonads of ... the Euphausia superba) and acoustical (differences in volume back-scattering strength of krill ... aggregations MVBS at 38, 120 and 200 kHz) were examinated. Comparing the depth of the net and acoustic ...

10. Management of C. gunnari in Subarea 48.3

    Abstract:  The management of Champsocephalus gunnari at South Georgia is complicated by the ... likelihood of substantial periodic variation in natural mortality rates. These may be associated with ... increased consumption of icefish by Antarctic fur seals in years of poor krill availability. Thus natural ... mortality of icefish may, in some years, increase by a large factor (assumed here to be 4) declining to ...
