抄録

Feeding experiments of the n-3 highly unsaturated fatty acid (n-3 HUFA) requirement on larval red seabream were conducted three times using rotifers enriched by the direct method, which showed a direct relationship between the n-3 HUFA concentration in emulsified lipids and the level on n-3 HUFA in rotifers. Various emulsions containing different levels of n-3 HUFA were prepared by mixing methyl oleate with pollock and cuttlefish liver oils or a methyl ester mixture containing 85% of n-3 HUFA and fed to rotifers. These rotifers were fed to larval fish for 10-16 days in 100l tanks.<br>The larvae fed on rotifers containing a low percentage of n-3 HUFA showed a poor growth and a high mortality. The growth, survival and activity of the larvae were effectively improved by elevation of the n-3 HUFA levels in rotifers, and reached a plateau at a level of 0.4%. The levels of n-3 HUFA in fish increased gradually as elevation of the percentage of n-3 HUFA in rotifers and reached a maximum at around 3% of n-3 HUFA (whole body dry basis). These results suggested that a minimum requirement of larval red seabream for n-3 HUFA is about 0.4% in wet basis of rotifer.
