Skeletal muscle growth dynamics and expression of related genes in white and red muscles of rainbow trout fed diets with graded levels of a mixture of plant protein sources as substitutes for fishmeal

Abstract : Juvenile rainbow trout were fed to visual satiation for 12 weeks with four diets containing fishmeal as the primary protein source (FM diet) or FM substituted with graded levels of a mix of plant proteins to replace 50% (PP50 diet), 75% (PP75) or 100% (PP100) of fishmeal with addition of crystalline amino acids to meet the requirements in indispensable amino acids. Growth performance, feed efficiency and protein efficiency were not affected by 50% fishmeal substitution but all decreased with higher substitution levels (FM = PP50>PP75>PP100). Ammonia excretion was inversely changed with FM substitution level (FM = PP50
