摇蚊科幼虫和水蚯蚓是池塘中最常见的底栖动物,它们是水域中饵料生产力的重要组成部分,准确地揭示它们在池塘中的分布规律,以提供合理的采集方式.为种群数量消长的分析以及深入其生物量和生产力研究的重要前提。对底栖动物群落结构的研究,我国陈其羽(1980),邓一德(1988)等曾有探讨。为了更深入了解,作者在1987年8月至11月,对大连市明泽池和校属金州渔场204池的摇蚊科幼虫和水蚯蚓进行了调查研究。
Chironomidae larvae and water earthworms are the most common zoobenthos in ponds and are important components of the productivity of water in the ponds and accurately reveal their distribution patterns in ponds to provide a reasonable method of harvesting Analysis and an important prerequisite for further studies on biomass and productivity. The study of zoobenthos community structure has been discussed in China, such as Chen Qiyu (1980) and Deng Yide (1988). In order to gain a better understanding, the authors conducted a survey of Chironomidae larvae and water earthworms in the Mingzechi of Dalian and 204 reservoirs of the Jinzhou Fishery Farm from August to November 1987.
