| The study investigated the effect of dietary supplementation with savory (Satureja hortensis) extract (SE) on stellate sturgeon (Acipenser stellatus) growth and health status. The fish with an initial body weight of 68.94±2.8 g were allocated randomly into 9 tanks, with a stocking density of 5 fish per tank and were fed with an un-supplemented diet (control, SE0), 1% SE (SE1), and 2% SE (SE2) for 8 weeks in freshwater. After 8 weeks, the feeding was stopped for 24 h and the blood samples were collected to measure immune parameters. The results showed that SE2 exhibited significantly higher values for final weight (164.67 g), specific growth rate (1.55 %/day), and weight gain (95.90 g) as compared to the SE0 (p<0.05). No statistically significant effects were noted among the experimental treatments in terms of the survival rate (p>0.05). The experimental diets significantly affect hematocrit and the highest level was observed in SE2. Total immunoglobulin, lysozyme, and ACH50 levels were significantly higher in the supplemented diets (p<0.05). The present study demonstrates that the administration of savory extract can improve the growth and immunity in stellate sturgeon. | ||
