Abstract


A study was carried out to determine the influence of dietary phospholipids biochemical factors parameters of beluga sturgeon (Huso huso) juveniles. Juveniles were fed formulated diet with four varying dietary levels of PL, that is, 0 (D1), 2 (D2), 4 (D3) and 6% (D4). At the end of the experimental period (56 days), there were no significant differences (P > 0.05) found for hepatic enzymes among treatments. The enzyme alanine aminotransferase (ALT) was highest in fish fed diet D2, while the lowest was found in fish fed diet D1 with values of 46.07 and 24.70 (IU/L), respectively. The enzyme aspartate aminotransferase (AST) was found highest in fish fed diet D3 and lowest was found in fish fed diet D2 with values 16.43 and 12.47 (IU/L), respectively. The enzyme lipase was found to be highest in fish fed diet D4, while the lowest was shown in fish fed diet D3 with values of 32.47 and 29.03 (IU/L), respectively. Among the biochemical factors, there was a significant difference (P < 0.05) observed in blood sugar, in which case, the highest reading was found in fish fed diet D3 with amount of 83 mg/dl and the lowest amount was found in fish fed diet D2 with a value of 46 mg/dl. However, the other biochemical parameters such as cholesterol and triglyceride did not showed significant differences (P > 0.05) among treatments. The triglyceride values ranged from the highest and lowest values were found in fish fed diets D4 and D2 with values of 349.33 and 263.00 (mg/dl), respectively. The cholesterol values which ranged from the highest to lowest were found in fish fed diets D4 and D2 with values of 121.67and 104.67 (mg/dl), respectively.

Key words: Phospholipids, sturgeon fish, Huso huso, biochemical factors.
