Effect of Varying Levels of Protein From Different Plants Sources on Growth and Survival of Carp, Cirrhinus Mrigala Reared in Cemented Cisterns.

Abstract

A total of 210 Cirrhinus mrigala fingerlings were distributed in completely randomized way into six treatments with 3 replicates each to determine the effect of protein from different plant sources on the growth and body composition of C. mrigala. Six experimental protein diets of varying protein level were formulated utilizing rice protein and rice bran viz.; as plant protein source like rice protein with 30% protein (RP30), rice protein with 35% protein (RP35) and rice protein with 40% protein (RP40). Similarly rice bran as protein source like rice bran with 30% protein (RB30), rice bran with 35% protein (RB35) and rice bran with 40% protein (RB40). Controlled group diet contained a balanced mixture of proteins from both plant sources. The daily feed ration was 8% body weight of fish. Highly significant (P<0.001) results were observed with respect to growth and body composition parameters. Highly significant (p<0.001) results were observed with respect to growth and body composition parameters. In conclusion, RB40 showed better growth performance of C. mrigala reared in cemented cisterns.
