Five different test diets were prepared as a control diet without added salt, and four diets with 0.5, 1.0, 1.5 and 2.0% added salt. Fish (20.15 ± 0.21 to 20.65 ± 0.64 gm /fish) was randomly distributed into the aquaria at a rate of 12 fish / 40 L . The water temperature was in the region of 27 ± 0.130 °C. Fish were fed either a diet containing 0.5, 1.0, 1.5 and 2.0% sodium chloride with a feeding rate of 3% of life body weight twice daily for 7 days a week for 60 days. No significant difference between the treatments was noticed. The best Final body weight, percent weight gain, and specific growth rate (SGR) were found with 1.5 % salt diet (P<0.05), whereas the lowest growth was gained in 2% salt. Generally, Food conversion ratio (FCR) and food conversion efficiency (FCE) were improved for carp fingerlings fed on diets contain NaCl ranged from 0.1 to 1.5% (P<0.05). The results suggested that dietary supplementation of NaCl influenced the body composition and can be beneficial for the young common carp reared in freshwater used in the fish culture.
