Abstract

The objective of the present study was to enumerate the effects of feeding volume on growth rate of Schizothoraxrichardsonii fingerlings. A 30-days experiment was conducted to study the feed conversion ratio (FCR) of S. richardsonii fingerlings. FCR was calculated of the three treatments, T1 (basal fish feed), T2 (Periphyton) and in T3 (both periphyton and basal fish feed). Twenty fingerlings of 0.35 g average body weight were randomly stocked in each treatment. The feed was given at a rate of 4% of the wet body weight of the fingerlings. The fingerlings fed with both periphytons along with basal feed of treatment T3 showed significantly higher average body weight (0.51gm) as compared to other two treatments. The study revealed that FCR showed significant result with the lowest FCR value (0.07) and were positively correlated with average weight gain of the fingerlings in the case of third treatment (T3), These results showed that in captive condition the feeding preference of S. richardsoniifingerlings was basal fish feed and periphyton under coldwater conditions
