Abstract

Feeding Frequency can affect various commercially important features such as increased biomass, growth and decreased ratio of foods, increased body weight, increased relative size, and improved tissue composition. Experiments were carried out in 100-liter fiberglass tanks containing 25 grams of 1.2 gram Rutilus kutum with a density of 0.5 g / L. The fish were divided into four treatments including 1, 2, 3, and 4 of Feeding Frequency. Each treatment was repeated 3 times. According to the Tukey test, there was a significant statistical difference between 2 treatment with 3 and 4 treatments, and also treatment 1 Feeding Frequency (P<0.05), considering food conversion rate (FCR), special growth rate (SGR), and weight gain (WG). The results showed that the maximum and minimum amount of weight gain has occurred in treatment3 (mean= 99.09±10.93) .and 1 (mean= 47.12±10.53), respectively. The minimum of the special growth rate (0.64±0.12) was observed treatment 1 and the maximum of that (1.15±0.09) was measured in treatment3. The minimum average of FCR (2.42±0.23) was referred to as treatment3 and the maximum of that (4.76 ±1.03) was referred to as thetreatment1 Feeding Frequency. Overall results showed that feeding three a day, the most appropriate method for growth Rutilus kutum,Fingerling
