Exploring the contribution of dietary protein from poultry by-product meal and fish meal to the growth of catfish Ictalurus punctatus by means of nitrogen stable isotopes

ABSTRACT The natural nitrogen stable isotope signatures (δ15N) found in poultry by-product meal (PBM) and fish meal (FM) were used to estimate the relative contribution of dietary nitrogen supplied by both ingredients to the somatic growth of juvenile channel catfish Ictalurus punctatus. Si...
