The effect of Different Levels of Ascorbic acid on the Growth Performance and Survival of Fingerling Common Carp Cyprinus carpio
Abstract
In this study effect of different levels of Ascorbic acid (AA) on growth, survival attributes in fingerling common carp were studied and optimum range of the vitamin was calculated in cultural condition. Thus, fingerling carps in 6.85±0.16g weighted were feed by SFC feed with 4 levels of AA (0, 100, 300 and 500 mg/Kg) during 8 weeks. The results showed that there were different between treatments in aspects of fish length and weight (P0.05). The fish were fed with 300 mg/Kg AA showed maximum weight and length gain and the minimum weight and length gain were showed in control and treatment of 500 mg/Kg AA (p0.05). According to results optimal level of AA to improve of growth performance for fingerling carp feed is 300 mg/Kg.
