Effect of different levels of hydroalcoholic extract of Viscum album on growth and hematological indices in Siberian sturgeon (Acipenser baerii)

The persent study was carried out to investigate the effect of different levels of dietary mistletoe (LM) on growth performance and hematological parameters of Siberian sturgeon (Acipenser baerii). Thirty six fish (mean initial weight 721.6±119.8 g) were fed 3 times a day with three different diets including 0, 50 and 500 mg/kg LM for 12 weeks. Biometry was done to calculate growth and nutritional indices every two weeks interval and six fish were randomly sampled at the end of experiment to measure hematological parameters. The obtained results showed that no significant difference in growth performance in comparison with the control group (P>0.05). However, the hematological parameters were not affected by LM hydroalcoholic extract (P>0.05). This study showed that using dietary LM did not have a significant effect on growth and hematological parameters of Siberian sturgeon.
