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

Para o bom crescimento dos peixes, é necessário alimentá-los com uma alimentação adequada e balanceada. Um estudo foi realizado para descobrir o efeito de diferentes dietas à base de proteínas em alevinos de Tor putitora (mahseer). Foi preparado um alimento com níveis de proteína dietética de 35%, 40%, 45% e 50%. O efeito de diferentes alimentos à base de proteína no ganho de peso, taxa de crescimento padrão (SGR), taxa de conversão alimentar (FCR), ganho de peso percentual, eficiência de conversão alimentar (FCE) e taxa de eficiência proteica (PER) foi estudado. Foi observado um aumento na taxa de crescimento com um aumento na concentração de proteína de até 45%. Os alevinos alimentados com dieta de 45% de proteína apresentaram o maior crescimento, seguidos de 50%, 40% e 35%. O valor de SGR foi maior para dieta com 45% de proteína (8,56), seguido de 50% e 40%, enquanto os menores valores foram observados para ração com 35% de proteína (1,57). A mesma tendência foi observada para FCE. Os maiores valores de PER foram observados em peixes alimentados com 45% de ração à base de proteína (0,65), seguido por 50% (0,56), 40% (0,38) e 35% (0,17). A taxa de conversão alimentar foi menor para a dieta com 45% de proteína (3,41), enquanto a maior para a dieta com 35% de proteína (16,85). Concluiu-se que a dieta à base de proteína de 45% foi a melhor formulação alimentar para maior produção de Tor putitora. No entanto, a pesquisa sobre a mesma porcentagem de dieta proteica é recomendada para animais de um ano.
