中文摘要	根据2001年5月至20002年5月间浙江北部沿海逐月采集所得1146颗婆罗囊螺生物学测定资料，并结合该螺野外生物学观察资料进行生长生物学综合分析。结果表明，该螺为软泥相潮间带数量优势种，垂直分布差异显著。喜阳，常出没于较干燥的海涂表面，栖息地受潮汐、光照和饵料分布调控；属明显集群繁殖类型，亲体产后大多死亡，一年生；5－9月为繁殖期，以6－7月为盛，6月下旬开始有幼螺群体出现，其生长速率在当年7－9月和次年4－6月各有一个高峰，11月－次年2月基本停止生长，肥满度以次年6月初为最高；壳高（H）与壳宽（B）成线性相关，其方程为B=0.3224+0.4916H (r=0.9770)，壳高与鲜重、干重呈幂函数相关，其回归关系方程分别为W_湿=2.110~(-4)L~(2.8352)(r=0.8448)、W_干=2.9710~(-4)L~(2.2803)(r=0.8939)；最后，还就杀灭婆罗囊螺的时机进行了探讨。
英文摘要	According to the biological data of 1146 snails R. bonieensis which were collected every month from May 2001 to May 2002, their biological observation data were comprehensively analyzed in the open country. The resulst indicate that this kind of snail Retusa borneensis, is of quantitative superiority in interval region of tidal zone with distinctive difference in vertical distribution^ Preferring sun light, it always appears and disappears at the surface of arid sea-tidal flat. Its habitats are regulated by the distribution of tidal, sunshine and bait. It is evident collective reproduction with breeding period from May to September. Especially it teems in June and July and lives only one year and dies after reproduction. The young snails first appear at the late June. Its growth rate reaches the peak during July to September and April to June of next year, From November to January of next year, it almost stops growing. It is the stoutandest and strongest in the July of next year. The height and the width of the snails are linear interrelated, with equation: B - 0.3224 + 0.4916H (r = 0.9770). The height of the snails and their fresh and dry weight are functional related, with equation: W_(wet) = 2.1 * 10~(-4) L~(2.8352)(r = 0.8448), W_(dry) = 2.91 * 10~(-4)L~(2.2803), (r = 0.8939). In the end, the matter of the opportune moment to kill the snails is also discussed.
