Abstract

The main goal of  the current study is to evaluate the impact of dietary herbal on the  growth performance of growth out  rainbow trout. This project was conducted at Caspian sea research institute of ecology from 2017 to 2018. Totally 180 rainbow trout with an average weight of 28.8g were randomly distributed to 9 fiberglass tanks with area  and depth of 1m2 and of 0.6 m.  The experiment lasted for seven weeks and the rainbow trout were fed by three different diets as follows: 1. Commercial pellet contained no herbal additive (control diet) 2. Commercial pellet contained 2% dietary herbal and 3. Commercial pellet contained 4% dietary herbal.  The results showed that fishes weight gains for diet 1, 2 and 3 were 28.62, 30.41 and 30 respectively. The estimated growth rate was 1.33g for control diet, 1.52g for 2% inclusion of the additive and 1.44g for 4% inclusion of the additive. Results also showed that inclusion of the additive did not change statistically average final weight (p>0.79).  A larger weight gain was observed at 2% additive inclusion although this was not statistically different with other treatments. In conclusion, with regard to the observed results, dietary herbal administration cannot improve growth, feed conversion rate and weight gain in oncorhynchus mykiss.
