Total replacement of fishmeal with soybean meal in diets for Nile tilapia in pre-fertilized ponds

Abstract

This study was conducted to investigate the effect of replacing fishmeal with soybean meal in diets with different levels of dietary protein on the production economics of Nile tilapia. The results demonstrate that soybean meal could replace the fish meal in diets for Nile tilapia without negative effects on growth, or on total production and even leading to high net economic returns in case of using diets with 25% protein from plant source.
