目前现代生物工程技术、水处理技术、自动监测控制等高新技术在水产养殖中应用越来越广泛,但是随之带来的问题也越来越明显,其在大幅度提高产量、推动水产养殖业发展的同时,对自身所依赖的水环境的破坏也日益加剧,水体的负载达到或超过饱和程度,进而使水体的理化条件不断恶化,水体的氨氮、亚硝态氮等有毒有害物质大量产生,致使养殖品种容易生病甚至中毒死亡,往往会造成较大的损失。 At present, high-tech such as modern bioengineering technology, water treatment technology and automatic monitoring and control are applied more and more widely in aquaculture, but the consequent problems are also more and more obvious. They are greatly improving the output and promoting aquaculture At the same time, the destruction of the water environment on which it relies itself is also aggravating. The load of water body reaches or exceeds the saturation level, which further deteriorates the physical and chemical conditions of the water body. A large amount of toxic and harmful substances, such as ammonia nitrogen and nitrite nitrogen, As a result, the cultivated species are easy to get sick or even poisoned, which often leads to great losses.
