Effects of dietary lipid, L-carnitine and L-lysine supplementation on the growth performance and body composition of Epinephelus lanceolatus larvae

The effects of different combinations dietary lipid, L-carnitine and L-lysine on the growth performance fatty acid profiles larval grouper Epinephalus lanceolatus were evaluated. Eight treatment diets formulated based a 2x2x2 factorial design, namely 5 14% oil mixture (3:1 fish oil/soybean oil), 0 0.5% 2.83% L-lysine. Each diet was randomly assigned to triplicate groups ten 0.08g E. larvae for 42 days. fed with containing lipid had significantly higher weight gain percentages than those 5% lipid. percentage both without added found be highest, while addition failed have any additive effect performance. With being 14%, not only but also is able decrease increase protein levels in muscle. supplementation high level reduce liver groupers. n-3 highly unsaturated (n-3 HUFA) analyzed from muscle supplemented lower devoid L-carnitine. This study indicated that are enhance larvae.
