Abstract

The effect of docosahexaenoic acid (DHA) and vitamin E (VE) on the development of larval yellowtail Seriola quinqueradiatawas examined by feeding them rotifers enriched withEuglenasupplemented with DHA and different types and levels of VE (dl-α-tocopherol and dl-α-tocopheryl acetate) .<BR>The crude lipid content and fatty acid composition of total lipids in rotifers were reflected by those levels inEuglena. A positive relationship was found between VE content inEuglenaand the incorporation of lipid in rotifer. Regardless of its type, VE was accumulated and incorporated VE acetate was not converted to free-type in rotifers. A maximum concentration of VE was obtained in rotifers fedEuglenasupplemented with VE acetate. However, VE was not detected in whole body of larvae in any of the groups, suggesting that larvae could not metabolize VE in rotifers derived fromEuglena, and it was not confirmed that the effect of VE on survival and growth of larval yellowtail.<BR>Larvae fed rotifers enriched with fresh waterChlorellahave shown poor growth, low survival rate, and poor activity, indicating that DHA has strong effect on early larval development of yellowtail.
