Effect of feed frequency on growth performances, feed utilization and biochemical composition of sterlet sturgeon, Acipenser ruthenus

The effect of feeding frequency on growth performance, feed consumption and body biochemical composition of Acipenser ruthenus juveniles was investigated. The trial was performed using 150 fish with a mean initial weight of 50±1 g randomly introduced in fifteen tanks. Fishes were fed at a feeding frequency of twice daily (T1), three times a day (T2), four times a day (T3), five times a day (T4) and six times a day (T5) at the rate of 3 percentage of wet body weight for 60 days. There was a significant difference (P0.05), in ash content. Based on the results of this study, five meals per day (T4) is recommended for juvenile sterlet sturgeon feeding.
