Abstract

The present study investigated changes in GROWTH and FATTY ACIDs profile in Acipenser persicus during larval development. The samples were obtained at 1th, 5th, 9th, 14th, 19th, 24th, 29th, 34th and 40th days post hatching. After yolk sac absorption in 9 day post hatching (dph) to 13 dph, fish LARVAE were fed with Artemia, then with Daphnia to the end of experiment. To analyze statistical results, one-way ANOVA was applied. The result of LARVAE GROWTH showed that the percent of weight gain in L-1 to L-19 and L-19 to L-40 were 494.5% and 828.9%, respectively. The result of live food FATTY ACIDs composition indicated that monounsaturated FATTY ACID (MUFA) source in Artemia was high (40.98±0.34%) and polyunsaturated FATTY ACID (PUFA) in Daphnia was higher (36.31±1.60%) than that of Artemia sample (P < 0.05). The result of FATTY ACIDs composition in the LARVAE showed that saturated FATTY ACIDs increased (40.20±0.78%) to L-29. In contrast, MUFA decreased (33/37±0/61%) until 34th day (P < 0.05). Duration of the experiment, PUFA and high unsaturated FATTY ACIDs (HUFA) had fluctuated. The result showed MUFA utilized as an important energy substrate in the PERSIAN STURGEON during ontogeny. Low dietary concentration of arachidonic acid and docosahexaenoic acid compared with that found in PERSIAN STURGEON LARVAE and also those LARVAE cultured in fresh water , it is suggested that the LARVAE is capable to convert linoleic acid and linolenic acid to HUFA.
