A 60-day feeding trial was conducted to evaluate the effects of yellow mealworm (YM) (Tenebrio molitor) (9%, 18%, 27% and 36%) and black soldier fly larvae (BSFL) (Hermetia illucens) (7%, 14%, 21% and 28%) meal replacing fish meal (FM) on growth performance and antioxidant capacity of red claw crayfish (Cherax quadricarinatus). Nine diets, including control, were fed with quadruplicate of 20 crayfish (0.20 ± 0.05 g). The highest weight gain (WG) and lowest feed conversion ratio were observed in crayfish fed YM18 and BSFL14. The highest superoxide dismutase activity and the lowest malondialdehyde content were detected in the hepatopancreas of the crayfish fed YM18 and BSFL14. Compared with the control group, crayfish fed BSFL14 had higher levels of glutathione peroxidase, catalase acid and alkaline phosphatase and the lowest malondialdehyde (MDA) content in hemocytes. The mRNA expression of CqBAF, HSP70 and MnSOD in the hepatopancreas of crayfish showed an increasing trend. Based on the second-order polynomial regression analysis of WG, the optimal dietary replacement level of FM with YM meal and BSFL was determined to be 21.9% and 17.1% for juvenile C. quadricarinatus.

水产养殖用昆虫粉替代鱼粉对鱼粉的生长性能、生理和抗氧化能力反应：以红爪螯虾（Cherax quadricarinatus）为例

进行了为期 60 天的喂养试验，以评估黄粉虫 (YM) (黄粉虫) (9%、18%、27% 和 36%) 和黑水虻幼虫 (BSFL) ( Hermetia illucens ) (7%)的影响, 14%, 21% 和 28%) 粉替代鱼粉 (FM) 对红爪小龙虾 ( Cherax quadricarinatus ) 生长性能和抗氧化能力的影响）。包括对照在内的 9 种饲料分别饲喂 20 只小龙虾 (0.20 ± 0.05 g)，一式四份。在饲喂 YM18 和 BSFL14 的小龙虾中观察到最高的增重 (WG) 和最低的饲料转化率。在饲喂 YM18 和 BSFL14 的小龙虾的肝胰腺中检测到最高的超氧化物歧化酶活性和最低的丙二醛含量。与对照组相比，饲喂BSFL14的小龙虾的谷胱甘肽过氧化物酶、过氧化氢酶酸性和碱性磷酸酶水平较高，血细胞中丙二醛（MDA）含量最低。CqBAF、HSP70和MnSOD的mRNA表达在小龙虾的肝胰腺中呈增加趋势。基于WG的二阶多项式回归分析，确定FM与YM粉和BSFL的最佳膳食替代水平对于幼鱼C. quadricarinatus为21.9%和17.1% 。
