According to the results of the registered trawling surveys carried out during the joint Soviet-French expeditions (1987-1988), more precise evaluations of the main commercial species biomass in the Kerguelen Islands area are given below. When evaluating the fish stocks, a special attention has been paid to the registration of hurricane samples zones and to the construction of their content evaluations. It is shown in the paper, that the total fish biomass is subjected to considerable variations and is in direct dependence on the quantity of the icefish year-class entering fishery.

Abstract:
The paper “The state of Dissostichus eleginoides stock and TAC for it for 1990/91 season in S.Georgia area (48.3)” presents the data on main biological characteristics of this species (Patagonien Toothfish), caught using long-line bishing in shelf waters of Shag Rocks and S.Georgia. While determining growth rate, size and age composition, natural mortality and catch statistics an attempt was made to determine total biomass of adult toothfish in the area under investigation and the value of possible catch at F0.1 and FMSY.
