Abstract

    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.

Key words: Growth performance, FCR, feed ingredients, hybrid fingerlings.
