| Semi-purified diets were used to feed gilthead sea bream larvae as first food from mouth opening until day 17. Four diets were formulated on the basis of a previous one used as control (D1). Three experimental diets differed only by the lipids added. One diet contained n-3 highly unsaturated fatty acids (n-3 HUFA) plus arachidonic acid (D2), one diet n-3 HUFA without arachidonic acid (D3) and one diet without n-3 and n-6 HUFA (D4). The three experimental diets contained 18:3n-6 in order to follow the influence of dietary HUFAs on elongation-desaturation capacities. Larval growth and survival were similar with diet D1 and D2. Lowest growth and survival were observed for larvae fed the HUFA free diet D4. Larval survival but not growth was significantly... |

| Recent advances have led to the development of inert diets for first-feeding marine fish larvae. The purpose of the present study was to evaluate fatty acid (FA) incorporation into larva using practical-type and semipurified diets as first food for larvae. Experimental microparticulate diets were fed to gilthead sea bream larvae, right from the mouth opening to day 21 post hatching. Five basal diets were compared, using fish meat or casein as main protein sources, and fish protein concentrate or casein hydrolysates and algae powder (Schizochytrium). Diets contained soybean lecithin to provide polar lipids and this also provided a high linoleic acid (18:2n-6) content. n-3 HUFA (1.5-1.7% DM) were mainly in dietary neutral lipids, with a part in polar lipids... |
