在上海水产大学上海崇明试验基地池塘养殖中发现，中华绒螫蟹辽河种群性早熟个体最初捕捉日期为8月15日，而长江种群为8月20日，二者相差5d。此后性早熟个体的捕捉数量逐渐上升，10月份达高峰期，11月份显著下降。在性早熟蟹群体中，辽河种群的性腺发育略领先于长江种群，而体重显著低于长江种群(P<0.01)；雌、雄性早熟蟹不存在显著的体重差异，但雌性个体数量明显多于雄性个体数量。

Combined with culture of juvenile crab in Chongmin experimental station, a comparative experiment was conducted on the precocious conditions of Yangtze population and Liaohe population of mitten crab (Eriocheir sinensis). The first catched date of Yangtze population was Aug. 15,and Liaohe population was Aug. 20. From that time, the number of catched prococious crab of both population climbed rapidly and reached the peak in Oct. The gonad of Yangtze population developed earlier than that of Liaohe population. In precocious population, the mean weight of Liaohe population was lower that of Yangtze population and sex difference in weight had no significance (P >0.05), but the number of male crab was much higher than that of female crab (P >0.05).
