抄録: Nutritional value of brown fish meal (BFM), soy protein concentrate (SPC) and corn gluten meal (CGM) for young yellowtail diets was evaluated by biological and biochemical methods. These proteins were incorporated at 30 - 50% of the diet as the only source of protein. The highest growth, feed efficiency, apparent protein digestibility, PER, NPU and BV were obtained from BFM-fed fish group while the lowest values were CGM-fed fish group, excluding BV which was similar between SPC and CGM. There was no apparent relationship between arginase or citrate synthase activities and protein sources. Blood urea nitrogen (BUN) and RNA concentrations of BFM- and SPC-fed fish groups tended to increase with increasing protein level, but those of CGM-fed fish group remained practically the same. Low protein utilization of SPC and CGM are attributed to their unbalance amino acid profiles and that of CGM is also due to poor digestibility. Among the examined biochemical parameters, BUN may provide useful indication for protein quality evaluation, though clear results were not obtained. At present, NPU and BV are useful parameters because clear growth differences due to dietary nutrition are seen in a rapidly growing fish such as yellowtail.
