What is it about?

Fish meal is a good source of protein, but its expensive price has kept it out of meals. As a result, alternative, cost-effective, and readily available fish meal substitutes should be considered. This study found that rice protein concentrate could be used as a cost-effective and beneficial ingredient to replace up to 25% of dietary fish meal in Nile tilapia diets while also improving growth performance, digestive and absorptive ability, and health status with the addition of synthetic amino acids.

Why is it important?

The current study demonstrates that rice protein concentrate can be used to replace fish meal in typical tilapia diets by increasing growth performance, nutrient utilization, and intestinal digesting and absorptive capabilities by up to 25%. This study also suggests that rice protein concentrate might be used as a cheaper alternative to fish meal in Nile tilapia feed formulations if synthetic amino acids are included.


Writing this article was a great pleasure as it was through scientific cooperation between the Academy of Scientific Research and Technology (ASRT) and the National Research Council of Italy (CNR) to Prof. Dr. Rasha M. Reda and Dr. Giulia Maricchiolo. This article also lead to transmission to a lot of experince in the fish nutrition feed between Egypt and Italy with the opening of new research horizons to serve the aquatic feed sector between the two countries
