| 摘 要： | １９９６－１９９７年对后潮铜锈环棱螺进行了周年研究，结果表明其种群含三个年龄组，其中１９９６年组生长最快，其去壳干重瞬时生长率为２．８０。采用瞬时生长率法测算其周年生产量为：带壳湿重３３．１３ｇｍ＾－２ａ＾－１；去壳干重１．９３２ｇｍ＾－２ａ＾－１；Ｐ／Ｂ系数为０．８５。

| Abstract: | An investigation on one of the dominant species of gastropods, Bellamya aeruginosa in Houhu Lake, Wuhan was carried out from April, 1996 to March, 1997. The results showed that the population was composed of three year classes, among which the 96 year class grew most quickly, with instantaneous growth rate of dry weight (unshelled) 2. 80. The annual production of the animal calculated by instantaneous growth rate method was: wet weight, 33. 13 g m-2 a-1; dry weight (unshelled), 1. 932 g m-2 a- 1. The corresponding annual P/B ratios was 0. 85. |
