Replacement of fish meal by plant protein sources up to 75% induces good growth performance without affecting flesh quality in ongrowing Senegalese sole

► High levels of plant protein (PP) blends were tested (50-75-100%) in ongrowing fish. ► Senegalese sole can use diets with PP sources up to 75% of fish meal replacement. ► Apparent digestibility coefficients of nutrients was similar among treatments. ► PP blends preserve high n-3 PUFA and DHA flesh content. ► PP diets did not affect the majority of sensorial descriptors of cooked slices.
