Biological characteristic and distribution of the green Notothenia by depth are given based on the results of inventory trawling surveys carried out in 1984/1985 and 1986/1987 by the BMRT "Gizhiga" in the Antarctic Peninsula subarea. Also presented are the abundance and biomass indices and the estimate of this species biomass by location and for the subarea on the whole. According to the investigation data, the green Notothenia biomass in the Antarctic Peninsula subarea amounts to 54.6 thous. tons.

Abstract:
Mesh selectivity experiments for several finfish species were conducted during the Spanish antarctic cruise “ANTARTIDA 8611” using the covered codend technique.
This paper presents the results obtained for Notothenia gibberifrons and Champsocephalus gunnari.
Selection factors calculated following different methods with a codend mesh of 68 mm were 2.87 for Notothenia gibberifrons and 3.10 for Champsocephalus gunnari.
