摘要: Turbot larvae reared on rotifers (Brachionus plicatilis) and Artemia (San Francisco brand) nauplii (A) were compared with those fed different copepod (Eurytemora affinis) stages (B). In one trial, growth survival of from hatching to day 21, their fatty acid pattern that food organisms examined. At the age 21 days group A measured 11·1 ± 1·6 mm total length (TL) 14·8 1·1 TL for B. From 3 8 was 29% 38% Long-chain polyunsaturated composition turbots resembled corresponding diets. lacking 22 : 6 n-3 acid. In a further study, 11 (C) or copepods (D) found be greater latter diet (73 versus 93%) whereas during this experiment similar in both groups. Before start trial they had been mixture Brachionus. No influence weaning success observed. is seen essential turbot larvae: elongations acids by not found.
