中文摘要:
      本文报道了长江水系和辽河水系中华绒螯蟹在安徽省女山湖围网区的生长性能的研究结果。(1)两水系河蟹的生长速率各月略有差异,长江蟹3月-7月生长速度稍低于辽河蟹,但差异不显著(P〉0.05);8月-10月份长江蟹生长快于辽河蟹,差异极显著(P〈0.01)。(2)辽河蟹青春期蜕壳时间比长江蟹提前30d,生殖洄游期也相应提前30d。(3)两水系河蟹养成的商品蟹规格、增重倍数和回捕率差异极显著(P〈0.01)。综合分析认为,长江蟹在淮河流域湖泊中网围养殖的生长性能指标优于辽河蟹。
英文摘要:
      This paper reports the variations in growth performance of Chinese mitten crab (Eriocheir sinensis) originated from the Yangtze and Liaohe River, cultured in the pens seated at the Rushan Lake, Huhe river system, Anhui Province. (1)The growth rate of two crabs from two river systems appeared a slight difference in various months, compared with the Liaohe river crab, the Yangtze river crab showed a lower growth rate from March to July without significant difference (P>0.05), but better from August to October significantly (P<0.01). (2)Compared with the Yangtze river crab, the breeding molting and spawning migration of the Liaohe river crab was 30 days earlier respectively. (3)The harvest size, body weight gain and recapture rate of stocking seed between these two crabs were different significantly (P<0.01). Comprehensively say, the growth performance of the crab from the Yangtze river was better than the crab from the Liaohe river when they cultured in pens at lakes of the Huaihe River system.
