Abstract
The main goal of the study was to evaluate the effects of different protein and energy levels on growth performance of Asipenser persicus fry. The fish were fed nine experimental diets containing three protein levels (35, 40, and 45%) and three energy levels (16.3, 18.2, and 19.4 kJ g−1 dry matter) according to a 2 × 2 factorial design. The diets were assigned to 27 thanks with 50 fish in each, with three replicates for each treatment. Growth‐related parameters were improved with increase of dietary protein (P < 0.01). However a change in energy contents of the diets did not have any impact on growth performance. The interaction between protein and energy showed that effect of protein on growth parameters depends on energy levels of the diet. Protein efficiency ratio improved with an increase in protein content of the diet (P < 0.01). Persian sturgeon fry showed a lower individual variation in final weight by feeding on high‐protein content diets. In conclusion, A. persicus fry needs a diet containing 45% protein to attain maximum growth. Protein content of diet can induce individual variation in growth of Persian sturgeon fry.
