摘　　要：试验旨在评估脱脂黑水虻虫粉对青蟹营养品质的影响。选取健康、规格整齐、平均初重为5.2 g的青蟹幼苗480只,随机分到12个水泥池中(2 m×1.2 m×1.5 m),共分成4组,每组3个重复,每个重复40只青蟹幼苗。C组(对照组)青蟹饲喂基础饵料,H25组、H50组、H75组分别使用脱脂黑水虻虫粉等蛋白替代基础饵料中25%、50%、75%鱼粉,4种饵料等氮等能。试验期4周。结果显示,与C组相比,H25组和H50组蟹体的体长、体宽和体重显著升高(P<0.05),各试验组青蟹的体高显著升高(P<0.05),H25组和H75组蟹体肥满度显著升高(P<0.05)。与C组相比,H75组的蟹体半胱氨酸含量显著降低(P<0.05),多不饱和脂肪酸(PUFA)、PUFA(n-3)含量显著降低(P<0.05)。研究表明,脱脂黑水虻虫粉替代饵料中25%~50%的鱼粉时,青蟹生长效果最佳,具有较好的营养品质。The experiment was to evaluate the effect of defatted black soldier fly larvae meal on nutritional quality of Scyla paramamosain.A total of 480 healthy green crab seedlings with neat size and an average initial weight of 5.2 g were randomly divided into 12 cement ponds(2 m×1.2 m×1.5 m)and divided into four groups,with three replicates in each group and 40 Scyla paramamosain seedlings in each replicate.The crabs in C group(control group)were fed with basal diet,and 25%,50%and 75%fish meal in basal diet were replaced by protein such as defatted black horse fly meal in H25 group,H50 group and H75 group,respectively,the four diets were equal in nitrogen and energy.The experiment lasted for 4 w.The results showed that compared with group C,the body length,body width and body weight of crabs in H25 group and H50 group were significantly increased(P<0.05),the body height of crabs in experimental groups was significantly increased(P<0.05),and the body fatness of crabs in H25 group and H75 group was significantly increased(P<0.05).Compared with C group,cysteine content of crab body in H75 group was significantly reduced(P<0.05).Compared with C group,the content of PUFA and PUFA(n-3)in crab body in H75 group were significantly decreased(P<0.05).The experiment indicates that when 25%~50%fish meal is substituted for the diet,the growth effect of green crab is the best,the nutrition quality is better.
