Amago salmon Oncorhynchus masou ishikawae juveniles selectively bred for growth on a low fishmeal diet exhibit a good response to the low fishmeal diet due largely to an increased feed intake with a particular preference for the diet

However, the physiological conditions as well as the growth and feed utilization of selected juveniles were inferior to juvenile replicates fed a fishmeal-based diet. In addition, since the selected...
