This study was conducted to develop a soft dry pellet (SDP )with a low unsaturation for yellowtail in order to reduce the occurrence of various fish diseases due to in vivo lipid peroxidation progression as well as to improve the quality of the cultured fish. Three kinds of SDPs with different levels of unsaturation were prepared by mixing sardine oil and palm oil in ratios of 1 : 0 (diet 1), 1 : 1 (diet 2), and 1 : 2 (diet 3). Juvenile yellowtail weighing 83g or 116g were fed for two month on these SDPs. The average body weights of fish fed diets 1 and 2 were quite higher than that of fish on diet 3. Plasma TBA values and tissue lipid contents of fish fed diets 2 and 3 were lower than that of fish diet 1. After an intramuscular injection of phenylhydrazine, high plasma bilirubin content was observed in fish fed diet 3. Moreover, after the inoculation of rod-shaped bacteria causing jaundice, the highest TBA value and bilirubin content were observed in fish fed diet 3. These results suggest that replacement of sardine oil by palm oil in ratio of 1 : 1 as the dietary lipid may enable in the SDP for yellowtail.

本研究旨在开发一种低不饱和度的黄尾鱼软干颗粒（SDP），以减少由于体内脂质过氧化进程而导致的各种鱼类疾病的发生，并提高养殖鱼的质量。通过将沙丁鱼油和棕榈油以1:0（饮食1）、1:1（饮食2）和1:2（饮食3）的比例混合来制备三种具有不同不饱和度水平的SDP。使用这些 SDP 喂养体重 83 克或 116 克的幼年黄尾鱼两个月。饲喂饲料1和2的鱼的平均体重明显高于饲喂饲料3的鱼。饲喂饲料2和3的鱼的血浆TBA值和组织脂质含量低于饲料1的鱼。肌肉注射后苯肼，在鱼饲料3中观察到高血浆胆红素含量。此外，在接种引起黄疸的杆状细菌后，观察到最高的TBA值和胆红素含量3. 这些结果表明，以 1:1 的比例用棕榈油替代沙丁鱼油作为膳食脂质，可能有助于黄尾鱼的 SDP。
