| 摘 要： | 对长江水系和辽河水系中华绒螯蟹（Eriocheir.sinensis)在长江下游湖泊生长性能研究的结果：（1）生长速度在3－8月长江蟹稍低于辽河蟹,但差异不显著（P＞0．05）;9－10月长江蟹则快于辽河蟹,差异极显著（P＜0．01）。（2）青春期蜕壳时间辽河蟹比长江蟹提前30－40d,生殖洄游期也相应提前30－40d。（3）养成的商品蟹规格、增重倍数和回捕率,长江蟹优于辽河蟹,差异极显著（P＜0．01）。综合分析认为,长江蟹在长江下游湖泊的生长性能指标优于辽河蟹。

| Abstract: | Growth performance of young Chinese mitten crab ( Eriocheir sinensis) originating from the Changjiang and Liaohe Rivers in the downstream lakes of the Changjiang River was studied.The results showed (1)that growth rate of the crabs from the two water systems appeared slightly different in various months,and the Changjiang crab developed at a lower rate than the Liaohe River crab during the period of March to August with an insignificant variance between them ( p >0 05),but from September to October it was opposite,and with an extremely significant variance ( p <0 01);(2)that the breeding molting of the Liaohe River crab was 30-40days earlier than the Changjiang crab,as a result of which its breeding migration was accordingly advanced 30-40days;and (3)that the size,weight increment and recapture rate of the nurtured crabs from the two water systems were extremely significantly different ( p <0 01) According to comprehensive analysis,it was thought that the Changjiang crab was superior to the Liaohe River crab with respect to their growth performance in the downstream lakes of the Changjiang River. |
