AB  - Dietary  factors,  such  as  the  origin  and quality of the protein used, or the fatty acid composition of  broodstock  diets  has  been  studied  during  last years in order to produce good quality fish eggs and larvae. Previous studies in the European sea bass (<I>Dicentrarchus labrax</I>) have shown the effect of the Polyunsaturated Fatty Acids (PUFA) dietary composition on the reproductive performance. In another hand, krill, used as an alternative source of proteins, has improved the eggs and larvae quality in the red seabream (<I>Pagrus major</I>). The present study consisted in the evaluation of the spawning performance and the eggs and larvae quality throughout the two first reproductive cycles of captive European sea bass. Fish were fed with a control diet (ST), or similar diets including krill flour (K) or PUFA-enriched oil (RO). K diet induced, in comparison with ST, a fecundity improvement, at least during the first spawning period after the puberty. However,  this  krill  positive  effect  on  the fecundity improvement was not evident during the second spawning  period.  On  his  hand,  the  RO  diet  induced  the  best quality eggs and larvae, but reduced spawning parameters.
