Abstract
The present study was conducted to evaluate the rate of supplementary feeding in the growth of Indian major carps in culture based fisheries system. For this study four micro-water sheds were selected (Baga-Ka-Naka and Har-Ka-Naka) and two micro-water sheds (Bhimsagar and Mohamed Falashiya) supplementary feed (@ 1%) was given, while another two water sheds(Baga-Ka-Naka and Har-Ka-Naka) were treated as control and no feed was provided. The supplementary feeding revealed significant impact onthe fish growth by the application of feed. As such weight and length gain and specific growth rate (SGR) were significant impact. The net weight gain, net length gain and SGR were higher in Bhimsagar and Mohamed Falashiya as compared to Har-Ka-Naka and Baga-Ka-Naka. Though partial supplementary feeding was given (only 1% of body weight), but it resulted in higher growth as compared to those which were not fed. The water quality parameter in four micro-water sheds indicated more or less same trend. Therefore the difference in growth rate might be due to the application of feed in two micro-water sheds (i.e. Bhimsagar and Mohamed Falashiya). On the basis of results of present study, it is recommended to use supplementary feed in culture based fisheries for higher returns.
