Replacement of fish meal with soy protein concentrate in diet of juvenile rice field eel Monopterus albus

Among plant protein sources, soy protein concentrate (SPC) has lower anti-nutritional factors and higher protein content. The aim of this study was to evaluate the effect of replacing fish meal in diet of rice field eel Monopterus albus with soy protein concentrate on growth performance, serum biochemical indices, intestinal digestive enzymes and growth-related genes expression in skeletal muscle. Six isonitrogen (45% crude protein) and...
