Waste nonstandard fish combined with wheat bran filler in ratio 60:40 were used for production of new nontraditional protein component called Ribotricin. The aim of this study was to elucidate the effects of new protein component Ribotricin on growth performance, feed utilization and feed ingredients digestibility of carp (Cyprinus carpio L., 1758) fish.
The experiment (90 days) involved 160 carp reared in eight concrete tanks with an initial average weight of 0.046 ± 8.04 g in (RT) tank, and fish with an initial average weight of 0.047 ± 6.52 g in (FM) tanks.The experimental carp were equally divided into two groups of 80 (four replicates of 20 carp each). The obtained results at the end of the experiment, showed no significant differences between the groups` Body Weight (BW), Feed Conversion Ratio (FCR) Specific Growth Rate (SGR), Protein Efficiency Ratio (PER) (p> 0.05).
Based on the obtained data we can conclude that Ribotricin (RT) can be used as fish meal substitution in the diets of carp fish without adverse effects on the measured parameters.
