    Résumé

    The absolute and relative fecundity of Patagonian toothfish inhabiting areas of South Georgia Island and Shag Rocks were studied. The absolute individual fecundity of toothfish in relation to the size of specimens ranged from 56,3 to 567.5 thousands of eggs, averaging 152,9 thousands of eggs. Values of relative individual fecundity of toothfish varied from 4,1 to 13,0 thousands of eggs (averaging 8.19 ± 1,73 thousands of eggs ) per 1 kg of fish body weight. Our studies and the analysis of data published previously indicate, that Patagonian toothfish similar to the most of Notothenioids characterized by large eggs can be included in the fish group having a level of absolute fecundity and a low value of relative fecundity.
