Abstract: (6601 Views)
In this study the effect of five experimental diets and iso nitrogenic and iso energic with different protein sources with 4 replications for each treatment of narrow claw crayfish in a total of 15 aquariums in the form of a completely randomized design were evaluated. The main sources of supply of fish protein meal (F) and soy bean (S) and gradually from 100 percent fish meal diet with 100 percent soy bean was replaced. Experimental diets included F70/S30, F30/S70, F50/S50, F0/S100 and F100/S0. The results showed that diets F70/S30 F100/S0 and better results in weight gain, specific growth rate, the coefficient of utilization of protein, feed conversion and daily food consumption was been. There are no significant differences between diets F70/S30 F100/S0. In terms of economic justification for making commercial diets fed F70/S30 recommended.
