Five dietary lipid sources (fish oil, soybean oil, palm oil, rapeseed oil and linseed oil) were evaluated in juvenile red claw crayfish, Cherax quadricarinatus, based on the response of growth, antioxidant capacity, intestine histology, whole‐body composition, fatty acid nutrition and lipid metabolism. Crayfish were fed in quadruplicate net cages for 8 weeks. Crayfish fed diets with fish oil, soybean oil and linseed oil obtained significantly higher weight gain and specific growth rate than those fed the other two diets. Survival, condition factor and hepatosomatic index were not significantly affected by lipid sources. Lipid sources also do not affect the whole‐body composition of crayfish. Serum SOD, T‐AOC and GSH‐PX activities of crayfish fed the palm oil and rapeseed oil diets had a significantly lower value than those fed other diets. The minimum concentrations of MDA have been observed in crayfish fed the soybean oil diet. The activity of ACC in the hepatopancreas of crayfish fed the linseed oil diet showed the highest value, and the CPT‐1 activity was not significantly affected by different lipid sources. Crayfish fed the soybean oil diet showed significantly higher TC and TG contents in hepatopancreas than those fed other diets. Crayfish fed linseed oil diet had a significantly higher percentage of EPA, C18:3n−3 and Σn−3 PUFA in muscle than those fed other treatments. Most of the fatty acid compositions in the hepatopancreas had a close correlation to fatty acid compositions in diets. All findings in this study indicate that soybean oil is the advantageous lipid source for juvenile C. quadricarinatus which can reflect in satisfactory growth performance, antioxidant capacity and fatty acid nutrition of edible tissues.

饲喂不同脂质来源的红尾螯虾螯虾的生长，抗氧化能力，肠道组织学和脂质代谢

在少年红爪小龙虾，蕉色螯虾中评估了五种饮食脂质来源（鱼油，大豆油，棕榈油，菜籽油和亚麻子油），基于生长，抗氧化能力，肠道组织学，全身组成，脂肪酸营养和脂质代谢的反应。将小龙虾放入一式四份的网箱中饲养8周。用小龙虾饲喂鱼油，大豆油和亚麻子油的日粮比其他两种饲喂日粮的增重和比增长率显着更高。脂质来源对存活率，条件因子和肝体指数没有显着影响。脂质来源也不会影响小龙虾的全身成分。饲喂棕榈油和菜籽油日粮的小龙虾的血清SOD，T-AOC和GSH-PX活性值明显低于饲喂其他日粮的小龙虾。在饲喂大豆油饮食的小龙虾中观察到了最低浓度的MDA。饲喂亚麻籽油饮食的小龙虾肝胰腺中的ACC活性最高，而CPT-1活性不受不同脂质来源的影响也很大。饲喂豆油日粮的小龙虾显示肝胰腺中的TC和TG含量明显高于饲喂其他日粮的小龙虾。食用亚麻籽油饮食的小龙虾肌肉中的EPA，C18：3n-3和Σn-3PUFA的百分比显着高于其他饮食。肝胰腺中的大多数脂肪酸组成与饮食中的脂肪酸组成密切相关。这项研究的所有发现表明，大豆油是青少年的有利脂质来源 饲喂豆油日粮的小龙虾显示肝胰腺中的TC和TG含量明显高于饲喂其他日粮的小龙虾。食用亚麻籽油饮食的小龙虾肌肉中的EPA，C18：3n-3和Σn-3PUFA的百分比显着高于其他饮食。肝胰腺中的大多数脂肪酸组成与饮食中的脂肪酸组成密切相关。这项研究的所有发现表明，大豆油是青少年的有利脂质来源 饲喂豆油日粮的小龙虾显示肝胰腺中的TC和TG含量明显高于饲喂其他日粮的小龙虾。食用亚麻籽油饮食的小龙虾肌肉中的EPA，C18：3n-3和Σn-3PUFA的百分比显着高于其他饮食。肝胰腺中的大多数脂肪酸组成与饮食中的脂肪酸组成密切相关。这项研究的所有发现表明，大豆油是青少年的有利脂质来源C. quadricarinatus可以反映令人满意的生长性能，抗氧化能力和食用组织的脂肪酸营养。
