Effect of different protein based feed on the growth of mahseer

Abstract For the proper growth of fish, it is necessary to feed fish with a and balanced diet. A study was conducted find out effect different protein-based diets on fingerlings Tor putitora (mahseer). dietary protein levels 35%, 40%, 45%, 50% were prepared. The weight gain, standard rate (SGR), food conversion ratio (FCR), percent efficiency (FCE), (PER) studied. An increase observed in an concentration up 45%. fed 45% diet shown highest growth, followed by 50%, 35%. SGR value greatest for (8.56) while least values 35% (1.57). same trend FCE. PER fishes (0.65) (0.56), 40% (0.38) and35% (0.17). lowest (3.41), (16.85). It concluded that best formulation higher production putitora. However, research percentage recommended yearlings.
