    Abstract

    Analysis and summarizing extensive materials on size-weight and size-age composition of South Georgia icefish for 1965-1987 enabled producing reliable weight-length dependencies for males and females by season and specify Bertalanffy growth equation parameters. Mean value of natural mortality rate was estimated at 0.55.
