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.

进行了这项研究，以开发出较低的黄尾巴不饱和度的软干球（SDP），以减少由于体内脂质过氧化进展而导致的各种鱼类疾病的发生，并提高培养鱼的质量。通过将沙丁鱼油和棕榈油的比例为1：0（饮食1），1：1（饮食2）和1：2（饮食3）混合，制备了三种具有不同不饱和水平的SDP。在这些SDP上，重83G或116克的青少年黄尾巴被喂两个月。鱼类喂食1和2的平均体重比饮食3上的鱼的平均体重高。饮食2和3的血浆TBA值和组织脂质含量2和3的脂质含量低于鱼类饮食1。在肌肉内注射苯基氢氮酰内注射后，高血浆胆红素含量在Fish Diet 3中经过了高血浆胆红素的含量。在鱼粉饮食3中观察到胆红素含量。这些结果表明，棕榈油比1：1的棕榈油替代沙丁鱼油，因为饮食脂质可能在SDP中启用了黄尾巴。
