抄録

Feeding experiments with young and juvenile yellowtail, Seriola quinqueradiata, were performed to examine the use of non-fish meal diets formulated with soy protein concentrate, defatted soybean meal, corn gluten meal, meat meal, and poultry feather meal in combination. The fish weighing about 210g (Expt.I) or 8g (Expt.II) on average were fed the experimental diets for 113 or 41 days, respectively.<BR>The experimental non-fish meal diets showed good palatability to the young fish, but poor to the juvenile fish. In Expt.I, the normal growth and feed performances were obtained in young fish fed the non-fish meal diets for the first about 8 weeks of feeding, but thereafter growth was gradually retarded and high mortality was observed without regard to the dietary treatments at the end of feeding. A similar pattern was also obtained in Expt.II, although supplemental effect of amino acids was observed to some extent in juvenile fish. Moreover, the anatomical examination at the end of feeding revealed that both young and juvenile fish on the non-fish meal diets had green liver status, which was not found in the fish fed the control fish meal diet. This observation together with hemochemical assessments demonstrated that feeding non-fish meal diets resulted in physiological conditions inferior to the control for both sizes of fish.<BR>Thus, these results confirmed that the non-fish meal diets could not sustain normal growth and health conditions of yellowtail due to induction of green liver.
