Four isonitrogenous (350 g/kg protein) diets were formulated for juvenile red claw crayfish, Cherax quadricarinatus, with half of the dietary fish meal replaced by four commonly used plant protein sources (cottonseed meal, soybean meal, rapeseed meal and peanut meal). A diet without fish meal replacement was used as a control. An eight‐week growth trial was conducted to evaluate the growth and health of crayfish juveniles (6.71 ± 0.08 g) fed diets containing the five different protein sources. The weight gain and specific growth rate significantly decreased in the crayfish fed the peanut meal diet compared with those fed the control diet. Survival, hepatosomatic index and whole‐body proximate compositions were not significantly influenced by different dietary plant protein sources. Intestinal damage is accompanied by higher activities of glutathione peroxidase, alanine aminotransferase and aspartate aminotransferase, and decreased lipase activities were observed in the crayfish fed the peanut meal diet. Crayfish fed the rapeseed diet also showed the detached peritrophic membrane and the lower lipase activities than those in control. Moreover, the malondialdehyde content increased and acid phosphatase activity decreased in the haemolymph of crayfish fed the soybean meal diet compared with those fed the control diet. Compared with those fed the control diet, the significantly increased valine contents, the activities of alkaline phosphatase and amylase were found in the crayfish fed the cottonseed meal diet. All these results suggest that soybean meal, rapeseed meal and peanut meal were not suitable substitute sources of plant protein for fish meal because of their adverse influences. On the contrary, cottonseed meal can be a good choice for fish meal replacement in the diet of juvenile Cherax quadricarinatus, as it does not have adverse effects on growth and could even increase amino acid nutrition, immunity and digestion.

红爪小龙虾（cherax quadricarinatus）的生长和健康状况以四种四种典型的植物蛋白来源为食，代替鱼粉

配制了四种等氮（350 g / kg蛋白质）日粮，用于少年红爪小龙虾Cherax quadricarinatus，其中一半的饮食鱼粉被四种常用的植物蛋白来源（棉籽粉，大豆粉，油菜籽粉和花生粉）替代。没有鱼粉替代的饮食被用作对照。进行了为期八周的生长试验，以评估含有五种不同蛋白质来源的小龙虾少年（6.71±0.08 g）日粮的生长和健康状况。与饲喂对照膳食的小龙虾相比，饲喂花生膳食的小龙虾的体重增加和比生长速率显着降低。饮食，植物蛋白来源对存活率，肝体指数和全身附近成分没有显着影响。肠道损伤伴随着谷胱甘肽过氧化物酶，丙氨酸氨基转移酶和天冬氨酸氨基转移酶的较高活性，喂花生粉饮食的小龙虾中脂肪酶活性下降。与对照组相比，饲喂油菜籽的小龙虾还显示出营养膜的脱落和脂肪酶活性的降低。此外，与对照日粮相比，饲喂豆粕日粮的小龙虾的血淋巴中丙二醛含量增加，酸性磷酸酶活性降低。与对照日粮相比，棉籽粕日粮中小龙虾的缬氨酸含量，碱性磷酸酶和淀粉酶活性显着增加。所有这些结果表明，大豆粉，菜籽粉和花生粉由于它们的不利影响而不适合用作鱼粉的植物蛋白替代来源。相反，Cherax quadricarinatus，因为它对生长没有不利影响，甚至可以增加氨基酸营养，免疫力和消化率。
