摘　　要：实验旨在研究不同比例的干蛆粉对克氏原螯虾(Procambarus clarkii)生长性能的影响,确定克氏原螯虾养殖中干蛆粉的最适添加比例。实验选择360尾体重(10.25+0.05)g的克氏原螯虾,按照单因素实验设计原则,将其分为4个处理,每个处理3个重复,每个重复30尾。对照组克氏原螯虾投喂基础饲料,实验1组、实验2组和实验3组分别投喂含有20%、40%和60%干蛆粉饲料,干蛆粉等量替代鱼粉。实验周期为90 d。实验结束,检测各组克氏原螯虾的生长性能。结果显示,与对照组比较,克氏原螯虾投喂添加60%的干蛆粉显著降低了实验末重(P<0.05),显著降低了特定生长率(P<0.05),显著提高了饲料系数(P<0.05);而投喂添加20%和40%的干蛆粉对其实验末重、增重率、特定生长率、成活率及饲料系数无显著影响(P>0.05)。研究表明,克氏原螯虾养殖中使用20%~40%的干蛆粉替代鱼粉,对其生长性能未产生负面影响,在实际生产中可以使用40%的干蛆粉替代鱼粉。The experiment was designed to study the effects of different ratios of dried maggot powder on the growth performance of crayfish(Procambarus clarkii),and to determine the optimal addition ratio of dried maggot powder in crayfish culture.A total of 360 crayfish were selected for the experiment,which were divided into 4 treatments with 3 replicates of 30 crayfish each according to the principle of one-way experimental design.The control group of crayfish was fed with basal diet,while groups 1,2 and 3 were fed with 20%,40%and 60%dry maggot meal,respectively,with the dry maggot meal replacing fish meal in equal amounts.The test period was 90 days.At the end of the test,the growth performance of crayfish in each group was examined.The results showed that compared with the control group,feeding 60%maggot meal significantly decreased the end weight(P<0.05),significantly decreased the specific growth rate(P<0.05),and significantly increased the feed coefficient(P<0.05)of crayfish,while feeding 20%and 40%maggot meal did not have a significant effect on the end weight,weight gain,specific growth rate,survival rate and feed coefficient(P>0.05).The study showed that the use of 20%to 40%of dried maggot meal instead of fish meal in crayfish culture had no negative effect on their growth performance,and 40%of dried maggot meal could be used instead of fish meal in actual production.
