TY - CPAPER T1 - Effect of stripping frequency on turbot spawn quality.

The eggs expelled shortly after ovulation by means of a systematic fivefold a week stripping attempt of females, presented a high viability rate (72%) compared to that of eggs collected twice a week (46%) whereas the treatments did not have any effect on female fecundity. Increase of the stripping rhythm brought the hatching rates and broodstock fertilities respectively from 11% to 35% and from 20,000 to 65,000 larvae/kg of spawning female. The enhancement of egg quality and of the resulting larva production is discussed. Y1 - 1991 CY - International Council for the Exploration of the Sea, La Rochelle, France, 26 Sept.-1er Oct.1991.
