Two separate studies were conducted with Atlantic salmon (Salmo salar) reared in seawater. The first study investigated various in vitro and in vivo methods for the measurement of the quality of the protein in fish meals. The second study was designed to estimate the optimal dietary ratio of digestible protein (DP) to digestible energy (DE) for Atlantic salmon (0.5 -1.2 kg body weight). A second objective of the latter study was to investigate the effect of feeding diets varying in levels of digestible protein and lipid on the proximate composition, pigment deposition, and the total fatty acid profiles of whole-fillets of Atlantic salmon. Chemical (chemical composition, biogenic amines, total volatile basic-nitrogen, anisidine value, peroxide value, thiobarbituric acid value, and iodine value), in vitro (dilute-pepsin and multi-enzyme digestibilities) and in vivo assays using rats and fish as test animals were conducted on various fish meals. The results indicated that dilutepepsin digestibility was a ...
