This experiment was conducted to evaluate the effect of egg batches on larval feeding (11 days post hatch), survival, growth, development, and anomalous morphology in brown sole Pseudopleuronectes herzensteini. Total egg production and fertilized rate of egg batches collected at early phase were superior to those of egg batches collected at late phase during the spawning season. Significant difference of larval feeding was observed in each egg batch (p0.05). In terms of survival rate and incidence of normal morphology, egg batches showed larval sufficient feeding were significantly higher than those showed larval insufficient feeding (p0.05). These results suggested that egg batches affected seed quality of brown sole, and that not only the egg quality of egg batches but also monitoring larval feeding of egg batches was important for producing healthy seed in this species.
