泥鳅掘洞行为生态的研究进展

Research progress on behavior ecology of burrowing loach Misgurnus anguillicaudatus

泥鳅密集在底泥中掘洞,鳅洞为泥鳅提供了躲避高温酷暑和低温寒冬的有效场所,泥鳅掘洞与浮叶植物群落也存在紧密联系。通过从农田改造、水体改良和水生植物调控等方面,针对农田泥鳅的生物特性、鳅洞的生态特征及其影响因素进行调研综述,分析了泥鳅掘洞过程的响应变化和生态作用,探讨了浮叶植物在泥鳅有土与无土养殖中的应用技术,旨在为泥鳅的种养结合生态养殖、无土养殖和工厂化高密度育苗提供技术支持,为泥鳅野生资源的恢复和保护、改进泥鳅养殖技术提供理论依据。

Loach Misgurnus anguillicaudatus densely burrows in bottom sediment, the burrows effectively shelter loach body from hot summer and cold winter, meanwhile loach burrowing is closely associated with free floating-leaved plants in ponds. The paper summarizes the loach biological feature, the burrow properties and in- fluencing factors from three aspects ： farmland modification, water improvement, aquatic vegetation regulation, ana- lyzes the responding changes and ecological functions of loach burrowing processes, and discusses the application technique of free floating-leaved plant in loach ecological and soilless breeding, which can provide technique sup- ports for the agricultural combination of planting and breeding, soilless breeding and intensive industrial seedling, also can provide theoretic foundation to the recovery and protection of wild loach resources and further improve the traditional breeding technologies.
