On some problems of reproduction of ruff, Gymnocephalus cernuus (L., 1758) in the Lake D±bie
Changes in the Lake Dąbie ruff gonad maturity and egg diameter were studied. Absolute and relative fecundity values were calculated. The egg diameter distribution suggests portional spawning. The absolute fecundity was found to range within 13,338-82,233 and was most closely correlated with the tota...

| Summary: | Changes in the Lake Dąbie ruff gonad maturity and egg diameter were studied. Absolute and relative fecundity values were calculated. The egg diameter distribution suggests portional spawning. The absolute fecundity was found to range within 13,338-82,233 and was most closely correlated with the total fish weight. No effect of body size, age, and ovary weight on the relative fecundity was found. |
