| 摘 要： | 1999年6月至2000年5月对武汉东湖铜锈环棱螺的种群生态学进行了周年研究.铜锈环棱螺年均密度和生物量分别为92.2ind./m2和142.83g/m2,密度和生物量的高峰分别出现在6月(157ind./m2)和11月(20578g/m2);东湖铜锈环棱螺为一年一代,其一年中种群含有5个年龄组,其中1998年龄组占绝对优势.利用瞬时增长率法计算东湖铜锈环棱螺的周年生产量带壳湿重为91.56g/m2,去壳干重为5.32g/m2,P/B系数为0.64.同时研究了铜锈环棱螺的生产力动态变化,其生产量累积多数季节均有发生,且以1998年龄组占优. |

| Abstract: | Bellamya aeruginosa (Reeve) is a predominant benthic macroinvertebrate in many shallow lakes along the middle and lower basins of the Yangtze River, and there is little published information on its production in China by far. This paper dealed with the population dynamics and production of B. aeruginosa, a subtropical, shallow, eutrophic lake located near the middle reaches of the Yangtze River. B. aeruginosa was sampled monthly at the eleven stations in Lake Donghu from June 1998 to May 1999. The results s... |
| Keywords: | Lake Donghu in Wuhan B aeruginosa production P/B ratio |
