Rearing of larval red sea bream Pagrus major was performed by feeding with rotifers cultured in Chlorella vulgaris K-22 enriched with n-3HUFAs (mainly DHA). Results for larval growth, survival rate, activity, and air-bladder opening rate suggested the successful rearing of the red sea bream. The total content of n-3HUFAs in the larvae at the end of the rearing was even higher than the level immediately after hatching. It can therefore be concluded that the enhanced n-3HUFAs in C. vulgaris were effective via rotifer for the rearing of red sea bream larvae. The n-3HUFA-enriched C. vulgaris makes it possible to realize the rearing of red sea bream without a secondary rotifer-culture process for enhancement of n-3HUFAs.
