Abstract

     This study was carried out in the laboratories of fish for 90 days in 16 glass aquaria (60 cm, 40 cm and 30 cm/70 L) to investigate the effect of some organic acids salts on some growth indices of common carp fish Cyprinus carpio L. A 128 fish were used with an average weight of (40.8±1) gm. and have been distributed on eight treatments with two replicate and eight fish for each replicate. Formulated eight diets that equally iso-nitrogenous (33.85%) and iso-caloric (1535.605 KJ/gm) were investigated. Organic acids salts (Sodium lactate, Sodium acetate and Sodiumformate) were supplemented singly (0.5% of each salts) and mixed to the experimental diets (0.25% of each salts). The statistical results showed that treatments T6 (0.25% sodium lactate + 0.25% sodium formate) had the best studied growth parameters at the level of P≤0.05 which clarified by weight gain (41.05±0.25 gm) and food conversion ratio (2.8±0.02).
