Rotifers Fed with n-3 Highly Unsaturated Fatty Acid-enriched Chlorella vulgaris are Suitable for the Rearing of Larval Red Sea Bream Pagrus major

抄録

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 rotiferculture process for enhancement of n-3HUFAs.
