GROWTH PERFORMANCE AND FEED CONVERSION RATIO (FCR) OF HYBRID FINGERLINGS (CATLA CATLA X LABEO ROHITA) FED ON COTTONSEED MEAL, SUNFLOWER MEAL AND BONE MEAL

An experiment was conducted in six glass aquaria to study the growth performance and feed conversion ratio (FCR) of hybrid fingerlings (Catla catla x Labeo rohita) fed on sunflower meal, cottonseed meal and bone meal. Two replicates for each ingredient were followed. The feed was supplied at the rate of 4% of wet body weight of fingerlings twice a day. The hybrid (Catla catla x Labeo rohita) fingerlings gained highest body weight (1.62 ± 0.0 g) on sunflower meal, followed by cottonseed meal (1.61 ± 0.01 g) and bone meal (1.52 ± 0.0 g). The total length obtained by hybrid fish was 6.35 ± 0.05 cm on sunflower meal, 6.12 ± 0.05 cm on cottonseed meal and 5.85 ± 0.05 cm on bone meal. The overall mean values of FCR were lower (better) on sunflower meal (1.78 ± 0.05), followed by cottonseed meal (2.17 ± 0.01) and bone meal (2.46 ± 0.01). Thus, The sunflower meal and cottonseed meal, on the basis of growth performance and better FCR, can be included in the feed formulation for hybrid fingerlings
