ABSTRACT



The comparison of out-off-season spawning of two cultured ide stock were examined. The obtained results show, that is possible to reproduced ide a few months before their natural spawning season. Generally, the percentage of spermiation and ovulation was very high, as well as spawners survival. The biological quality of the gametes was higher in stock cultured at ponds, than from fish cultured under controlled conditions. One ide females from cultured stock under controlled conditions ovulated without hormonal stimulation (control group). The quality of oocytes collected from this fish was much lower than from hormonally stimulated fish.

Key words: artificial spawning, Leuciscus idus, reproduction, out-off-season spawning..
