Abstract

    A six-week experiment was conducted in aquaria to study the feed conversion ratio (FCR) in Cirrhinus mrigala fingerlings fed on wheat bran (13.81% protein), sunflower meal (35.52 % protein) and maize gluten (26.15% protein). The ingredients were supplied at the rate of 4% of wet body weight of fish twice a day. The fish gained the highest average body weight (0.31 ± 0.03 g) on sunflower meal followed by maize gluten (0.23 ± 0.01g) and wheat bran (0.19 ± 0.02g). FCR calculated for three treatments was highest for wheat bran (0.019) while for sunflower it was lowest (0.003). The correlation between average body weight and FCR values was significantly negative in case of wheat bran whereas in case of sunflower meal and maize gluten, the correlation was non-significant1y negative.
