The current study dealt with preparing of shrimp waste protein concentrate with different methods and using it for feeding of common carp (Cyprinus carpio). Four diets were manufactured: the first, a control diet containing traditional feed materials (c); replacement diets were prepared by completely replacing the fish meal with shrimp waste powder (T2); using physically prepared shrimp waste protein concentrate (T1), and employing chemically prepared shrimp waste protein concentrate (T3). The fish were fed for 90 days. The results of the current study showed that the treatment (T2) was significantly superior in weight gain, daily growth rate, relative and specific growth rate, food conversion rate, and protein efficiency rate, reaching 91.40g, 1.01g, 94.61%, 0.73%/ day, 4.52, 0.67, respectively. The results also showed that the replacement process was successful according to the measured parameters. In conclusion, the study demonstrated the potential use of this prepared shrimp waste protein concentrate as an alternative to imported fishmeal in formulating diets for feeding young common carp.
