    Résumé

    Regularities of growth are established from the data of age determinations and analysis of yellowfin notothenia length-weight composition, mathematical description of length-weight dependence and parameters of Bertalanffy equation are given. Natural mortality coefficient, M, calculated by six various methods ranged from 0.63 to 1.06. With mean value of M, age and length at optimum exploitation were 2.5 years and 12.5 cm, respectively.
