Kopiejewska W., 1993. Reserve of oocytes of protoplasmatic growth in the ovaries of bream, Abramis brama (L.) females from Lake Kortowskie and Lake Blanki. Acta Ichthyol. Piscat. 23 (2): 19-32.

1.5 to 14.5% of the oocytes develop in the annual cycle in the ovaries of bream females in Lake Kortowskie and Lake Blanki. This corresponds to 20.7-321.3 thousand eggs. An increase of absolute fecundity of the females takes place through utilization of the reserve of oocytes of protoplasmatic growth which are found in the ovaries during vitellogenesis from 1.5 to 14.5% as well as through an increase of the number of eggs per one per cent of oocytes in the ovaries.
