Biochemical constituents of raw and dried specimens of the freshwater fish Salmophasia untrahi was studied from Bhadra reservoir, Karnataka. The proximate composition of raw male Salmophasia untrahi revealed 71.18% moisture, 26.12% protein, 0.20% fat/lipid, 0.48% carbohydrate and 2.02% ash. In females, the level of moisture, protein, fat/lipid, carbohydrate and ash was 69.20%, 28.21%, 0.30%, 0.50% and 1.79% respectively. Females had relatively higher protein and fat content as compared males. The proximate composition of dried fish showed maximum and minimum occurrence of moisture, protein, fat/lipid, carbohydrate and ash contents during different seasons is attributed to variations in feed intake, water quality, stage of gonads , spawning and were greatly influenced by the breeding activity.
