Notes:
Fertilization, survival during incubation and hatching were highly correlated and strongly influenced by the female parent and the interaction between both parents of the sea bass Dicentrarchus labrax. A single significant male effect was detected on hatching and may reflect a genetic component determining survival from fertilization to hatching. Egg size and total length of 8-day-old larvae (age of first feeding) were also subjected to the influence of the female but the two parameters were not correlated. A significant interaction between both parents was also observed for length of larvae. The survival rates were significantly correlated in two consecutive years indicating that reproductive performances may be repeatable. Although the effect of the male parent on early sea bass development is shown for the first time, it seems that most of the parental effects on early performance in this species are due to females even when hormonal stimulations are performed at very close prematurational stages of oocyte development.
