Krill length and biological compositions in Subarea 58.4.2 based on Russian scientific observations

This paper presents the data on the length and biological composition of krill in areas of the Commonwealth Sea and the Cosmonaut Sea (Subarea 58.4.2) based on Russian scientific observations for the period 1972-1990. 

Using subarea 58.4.2 as an example, the data presented demonstrate complex spatial-temporal variability in the length and biological composition of krill, which needs to be taken into account when developing krill fishery management schemes in Area 58 (58.4.1 and 58.4.2-East) through the implementation of standardized comprehensive krill surveys. There is a lack of such surveys in Area 58.
