| 内容記述 | The estuary-caught fingerlings of Ayu (initial weight 6.5g) were fed the control (65% fish meal), the 30% and 60% chlorella (with 42% and 19% fish meal, respectively) and the SCP feed (32% acetic acid-grown Yeast and 38% fish meal) in outdoor tanks (water temp. 16-18.5°C) from May to September. About a half of the fish, however, was lost due to vibrio-disease at the beginning of the experiment. The best growth was obtained on the 30% chlorella diet followed by the 60% chlorella, control and SCP diets in the order. During June-July season effect of feeding frequency was examined. Twice a-day feeding brought about 1.09-1.26 times more growth rates than once-a-day feeding. From the end of July to September the effect of 4 % supplemental fish oil on the fish growth was compared with that of 8%. Scarce differences were obtained between the two levels. Lipid content of the trunk flesh was 14-15% in September and decreased to 1.8% in December. In the fatty acid (FA) composition 22 : 6 acids were 3.0-4.2% (∑ω3FA 10-11%) in September and increased to 13.2% (∑ω3 FA 22.1%) in December. The egg FA of the reared fish contained 1.9-4.1% of 18.3, 4.4% of 20: 5, and 14.8- 17.7% of 22 : 6 acids, while the wild fish egg 5.1%, 14.1%, and 9.2%, respectively. Qualities of the diet lipids for the brood fish were discussed. | |||||||||||

| 内容記述 | 海産稚アュを魚粉飼料,クロレラ,および酢酸資化酵母(SCP)配合飼料で飼育したのち,雌親魚の胴肉および卵の脂肪酸組成を分析した。飼育の結果は,30%クロレラ飼料区の成長がもっとも良く,SCP区の成長はわずかに劣ったが,飼育初期には大量のへい死があり,また末期には一部チョウチン病の発生をみる等,十分な比較には至らなかった。胴肉の脂肪酸組成では飼料区間の差はわずかに認められたが,卵においては飼料の影響はさらに小さくSCP区のみ22:6酸量がやや低かった。しかし天然魚卵の脂肪酸組成では,18:3および20:5酸量が著しく高いことから,親魚飼料に添加すべき脂質の性状について改善の必要を指摘した。 | |||||||||||
