Study on feeding and growth of larval Zhoushan flounder(Paralichthys olivaceus)

The experiment was conducted to study feeding and growth of Paralichthys olivaceus larvae.Results showed that larvae began to fed at the age of six days at 16~18℃, and the feeding rate was 30%.The highest feeding rate was 65% at the age of 8 days.P.olivaceus larvae arrived the point-of-no-return (PNR) at the 9th day.The period of mixed nutrition of the larvae was 3 days.The initial feeding intensity and the feeding rate were slowly increased to the peak when the yolk sac almost exhausted and decreased after that.With the starvation prolonged, unfed larvae entered a negative growth.The survival rate was 10% at the 11th day after hatching.
