Study of changing of chemical muscle content during maturation in Zebrafish (Danio rerio Hamilton, 1822) fed with prebiotic inulin

According to the importance of prebiotic inulin on sexual maturation in fish, this study changing the chemical composition (fat, protein, moisture and ash) in various stages of maturation muscle tissue in the zebra fish. Therefore, zebrafish larvae were fed with experimental diets containing (0, 1, 2 and 3 gr/kg diet) of inulin and two-stage sampling (45 days and 90 days after the active feeding) took place at every stage in the chemical composition (lipid, protein, moisture and ash) muscle tissue (based on the percentage dry weight) in fish muscle were measured. In the first sampling stage, fat and muscle protein was significantly higher than the second sampling stage (P<0.05). Given that the second stage fish were full sexual maturity, the amount of fat in muscle decreased (P<0.05). Moisture and ash levels were significantly (P<0.05) higher in the second stage sampling than the first stage. Overall, our results showed that different stage of living affected on muscle chemical composition muscle in Zebrafish.
