Studies were performed on the ovaries of 58 females of white bream, Blicca bjoerkna (L.), from Włocławek Reservoir to determine the character of spawning. Oocyte vitellogenesis in the germ line commenced at the beginning of April, fish reproduction in June-July. The examined females laid eggs in one or two portions.
