Abstract
In this study, the effect of different levels of protein in artificial diets on bioenergetics’ indexes of Snow trout juveniles (Schizothorax Zarudnyi) evaluated in 8 weeks. Eighty four Snow trout juveniles with average weight 14.71 ±1.05 g and length 13.5±0.8 cm fed with Isocarbohydrate and Isolipidic diets and varying levels of protein (D1 = 25%, D2 =30%, D3 = 35% and D4 = 40%). Seven advanced fry were stocked into each 50-l aquaria with triplicate in fore treatments and fed three daily at 5% body weight rate. Results indicated highest body weight gain (7.33±1.35), specific growth rate (0.68±0.11), and daily average gain (0.12±0.02) observed in D1 treatment group that fed by diet containing 25% protein that no significantly difference with other treatments (p.0.05). Highest protein efficiency ratio (0.11±0.02) and apparent net protein utilization (0.03 ±0.00) observed in D1 treatment group that significantly difference with other treatments. Also results of body composition of Snow trout juveniles (Schizothorax Zarudnyi) indicated except in the moisture rate that it has been affected significantly by different levels of dietary protein(p<0.05). Finds of this study indicated that optimum protein level in diet for optimal growth and nutrition indexes in Snow trout juveniles is 25%.
