Abstract

The present study is aimed to determine the growth performance of Indian major carp Labeo rohita fingerlings for a period of 60 days. 15 days aged fingerlings divided into two experimental groups E1, E2 and control (C). Two experimental groups incorporated with supplements like water probiotic Eco-Pro with Vitamin-C as E1, water probiotic Eco-Pro with groundnut oil cake and Vitamin-C as E2 compared with control. The maximum increase in length, weight and width of Labeo rohita fingerlings 6cm, 23 grams and 4cm respectively was observed in E2, 4% concentration of water probiotic Eco-Pro food supplement has given maximum Food Conversion Ratio (FCR) (0.01) and P.E.R (0.62) S.G.R (0.85). The food conversion ratio is strongly significant with P.E.R and S.G.R. The supplementation of probiotic in combination with Vitamin-C have proved remarkable effect on the amount of protein, lipid and carbohydrates, when compared to alone probiotic supplementation and also controlled Labeo rohita fingerlings. Hence it is concluded that the supplementation of probiotics in combination with vitamin-C and groundnut oil cake will be most preferable feed to obtain healthy with significant specific growth rate of fish to improve economic status of fish farmers as well as consumers.
