摘　　要：在江苏高邮市,对罗氏沼虾"南太湖1号"选育群体与未经选育的其它养殖群体进行了养殖对比试验。试验结果表明:选育群体在大塘养殖阶段具明显的生长优势,选育群体绝对增重率、瞬时增重率分别比非选育群体高0.01907g/d、0.242%/d。选育群体的平均产量增加64.5kg,增产20.6%;产值增加1758元/667m(2亩),增幅29.3%;利润增加1110元/667m2,增幅53.6%;饲料系数降低6.76%,养殖成活率增加8.87%。Comparative study of growth performance and cultivation profits was conducted in pond at Gaoyou,Jiangshu province between ＂South Tai lake NO.1＂selected breeding population and other population of Macrobrachium rosenbergii.The results show that the growth rate and cultivation profits of selected breeding population is significant higher than other population in pond cultivating phase. AGRw , IGRw, cultivation production per 667 m^2, production value per 667 m^2, profits per 667 m^2, survival rate of selected breeding population were 0.01907 g/d,0.242 %/d, 20.6%, 29.3%, 53.6%, 8.87% higher respectively,and FCR of selected breeding population was 6.67% lower than other population. The selected breeding population has good resistance to environment challenges and disease.
