Abstract

The effect of water temperature on sex differentiation was examined in European sea bass (Dicentrarchus labrax) of two strains from the Northwestern and Southeastern Mediterranean Sea, during larval or nursery rearing. Temperatures < 17 °C enhanced feminization, while 21 °C during larval rearing induced higher male% compared to the nursery stage, and the overall male% was significantly different among strains (P<0.05). The study shows that management of larval rearing temperature can prevent the high male% observed in cultured populations. © 2004 Kluwer Academic Publishers.
