摘要
藻类水华会释放大量毒素和有害物质,造成水生生物的大量死亡,给渔业生态环境带来严重危害。生物控制措施可以在一定程度上降低水体富营养化程度和控制藻类的过度繁殖,防止有害藻类大量爆发。主要生物控制作用包括,一方面促进水体生态系统的物质循环和能量流动,加速营养元素沉降或脱离水生生态系统;另一方面限制或抑制水华藻类的生长,使水体生态系统处于稳定的动态平衡。
Algae bloom will release toxins and harmful substances,cause organisms mass deaths in water,bring serious harm to aquatic ecological environment.The biological control measures can reduce eutrophication in some extent,control the undesirable algae breeding and prevent its massive outbreak.The main biological role include,1） promoting water ecosystems material circulation,energy flowing and speed up the settlement of nutrients from aquatic ecosystems;2） restricting or inhibiting the growth of the undesirable algae and keeping the water ecosystem in a stable dynamic equilibrium.
