    Parameters of the Bertalanfy growth equation for 1928 and 1970–1976 were calculated on the base of summaryed data on Krill age groups singled out using method of Harding.Parameters obtained were used to calculate total Krill mortality using different methods applyed earlier only to the fish recources.
    As a result of uncertainty in age groups determination were obtained wide ranging values. The most real values varied from 0.75 to 1,17.
    No fishery impact on various parameters of the krill population size structure was found.
