摘要: 作者研究了不同水系河蟹在长江中游湖泊养成后于秋冬季捕捞期间成蟹日产量动态特点。结果表明,盘锦苗种、天津苗种、长江苗种日产量高峰时间分别为9月上旬、9月中旬、10月上旬,瓯江苗种的高峰时间最早在10月19日,最晚出现在11月17日。苗种来源水系纬度(Y)与成蟹日产量高峰出现时间(X：天,8月28日为第一天)呈线性相关：Y＝43.182-0.232X(n＝13,r＝-0.96)。Abstract: The characteristics of daily catch of Chinese dritten crab, Eriocheir sinensis,from different water systems, stocked in Iakes at the middle reaches of Changjiang River, were studied in harvesting period during autumn and winter.The originated crabs from Panjing, Tianjin, Changjiang River, Oujiang River reached the peak of daily catch in the first ten- day of September, the second tenday of September, the first tenday of Octobef, and the period of October 19-November 17, respectively.The relationship between the latitude (Y) of water systems from which crah seedlings come and the time (X: day, the first day is August 28) of peak catch during harvesting period may be expressed as Y = 43.182 - 0.232X (n = 13, r = - 0.96).
