| Abstract |
| Purpose: Many studies have shown that prebiotic supplements can improve the digestive performance, growth parameters, and immunity in various fishes. However, there are few sources of information about the effects of these supplements on sturgeons, particularly Persian sturgeon. So, this study was conducted to assess the effects of yeast cell wall (YCW) prebiotic on the intestine and liver tissues of Persian sturgeons. Method: In order to accomplish this, a total of 153 juvenile Persian sturgeons, with average initial weight of 47.78 ± 0.39 g were distributed into nine 500L tanks. For 8 weeks, fish were fed basal diets with 0.5% and 1% prebiotic supplements, as well as a control diet with no prebiotic supplement (0%). At the ending of the feeding trial, 2 individuals from each tank were sampled for histological examination. Results: The histological analysis reveals varying degrees of tissue damage in the intestine and liver of fish across different treatment groups. Notably, fish in the control treatment exhibited significantly less tissue damage in multi parts of the intestine and liver compared to other two treatments. Conclusions: According to the findings, the damage detected in the intestine and liver could be attributed to YCW prebiotic type, its dosage, and environmental factors. The observed reduction in tissue damage in the control treatment suggests that YCW supplementation at 0.5 and 1% in the juvenile Persian sturgeon diet is not recommended. |
