Replacement of fish meal by pea protein concentrate in practical diets for juvenile crayfish (Pacifastacus leniusculus Dana, Astacidae) from the onset of exogenous feeding

► A 100-day experiment was conducted with juvenile crayfish (P. leniusculus, Astacidae). ► We tested levels of pea protein concentrate (PPC) from the onset of exogenous feeding. ► Levels of PPC were related to the amino acid content of diet and survival and growth.
