Partial replacement of fishmeal by animal protein with supplement of diets in freshwater fish Rasbora daniconius (Hamilton, 1822) and Puntius ticto (Hamilton, 1822)

Abstract

The aim of this study was to evaluate the effects of two diets, artificial fish feed (Diet I) and animal protein (Diet II) as fish meals. These diets were fed to two different groups of fishes, Puntius ticto and Rasbora daniconius. During the experiment the survival rates were 100%. Diet II mainly contained mollusc protein compared to Diet I. The growth performances were studied after feeding Diet I and Diet II for 25 days. At every 5th day of feed intake, feed conversion ratio, gross feed conversion efficiency, growth coefficient of body weight and total length were studied. We found no significant increase in Diet II for the mentioned factors. The specific growth rate, percentage of body weight and total length increase showed a statistically significant increase.
