摘要
近年来以鲢(Hypophthalmichthys molitrix)、鳙(Aristichthys nobilis)等滤食性鱼类为主要放养对象的非经典生物操纵方法在水体修复中的应用越来越多,效果明显,但在清除浮游藻类的同时也会带来其他问题。本文分析了非经典生物操纵方法中几种滤食性鱼类在淡水生态系统中的应用以及存在的问题,并从生物链和生态平衡角度分析,将滤食性鱼类与其他水生动、植物混养协同优化水体生态系统结构,增强对水体的修复效果,维护生态平衡。
In recent years,non-classical biological manipulation methods with filter-feeding fish such as silver carp(Hypophthalmichthys molitrix)and bighead carp(Aristichthys nobilis)as the main stocking objects have been applied more and more in water body restoration,and the effect is obvious,but while removing planktonic algae,it will also bring other problems.In this article the application of several filter-feeding fish in freshwater ecosystems and the existing problems in non-classical biological manipulation methods were analyzed,and the biological chain and ecological balance was analyzed from the perspective of the synergistic effect of filter-feeding fish with other aquatic animals and plants,to optimize the structure of the water ecosystem,enhance the restoration effect of the water body,and maintain the ecological balance.
