Abstract:

Selenium is one of the most essential trace elements in fishes. Therefore, determining the optimal level of selenium in the fish diet is one of the main concerns of researchers. This study investigated the effects of Sel-Plex (Selenium yeast) supplement on the hematological parameters and immunological parameters, and growth performance in Siberian Sturgeon, Acipenser baerii. The Siberian Sturgeon fed with diets supplemented with 0 (control), 5, 10 and 15 g kg-1 Sel-Plex feed for 8 weeks. Growth performance, hematological parameters, total immunoglobulin, alternative complement activity (ACH50), C3 and C4 levels and lysozyme activity were measured at the end of the experiment. No significant differences have been observed (p>0.05) in weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR) and condition factors (CF) in the fish fed with different concentrations of Sel-Plex supplement when compared with the control group. The results showed that administration of 10 g Sel-Plex in this fish significantly increased erythrocyte, hemoglobin levels, hematocrit value, leukocytes, and lymphocytes counts. However, neutrophils of fish administrated with 10 and 15 g dietary Sel-Plex significantly decreased. The results revealed that Sel-Plex significantly increased total immunoglobulin, ACH50, C3, and lysozyme activities in the supplemented groups compared with the control. Plasma C4 levels in the fish fed with 5 and 15 g Sel-Plex were significantly higher than the control fish. The results of this study suggest that dietary Sel-Plex supplement at levels ≤15 g kg-1 diet increased some hematological indices and improved the innate immune parameters of the Siberian Sturgeon, without affecting their growth performance.

The effect of dietary dextrin levels on growth performance, body composition and hepatosomatic index in juvenile Siberian sturgeon, Acipenser baerii

The present study was carried out to determine the ability of Acipenser baerii in utilizing carbohydrate (dextrin) as a non protein energy source substituted with animal oil. A total of 65 juveniles A. baerii with an initial mean weight of 689 ± 62 g were distributed in 15 fiber glass tanks. Five diets were formulated including 0, 5, 10, 15 and 20% of dextrin and fed  for 8 weeks. Fish were wei...

Five hundred and ninety two Siberian sturgeon (A. baerii) fingerlings (average weight, 11.1±0.9 g) were randomly distributed in 16 tanks (150 L) at a density of 35 fish per tank and fed different treatments (Control, degrading bacteria, 2% PHB, degrading bacteria + 2%PHB) for 60 days. At the end of the experiment, the results indicated that the fish fed PHB or bacteria treatments had low midgut...
