Strict environmental restrictions force the aquaculture industry to guarantee optimal water quality for fish production in a sustainable manner. The implementation of anammox (anaerobic ammonium oxidation) in biofilters would result in the conversion of both ammonium and nitrite (both toxic to aquatic animals) into harmless dinitrogen gas. Both marine and freshwater aquaculture systems contain populations of anammox bacteria. These bacteria are also present in the faeces of freshwater and marine fish. Interestingly, a new planctomycete species appears to be present in these recirculation systems too. Further exploitation of anammox bacteria in different compartments of aquaculture systems can lead to a more environmentally friendly aquaculture practice.
严格的环境限制迫使水产养殖业以可持续的方式保证鱼类生产的最佳水质。在生物过滤器中实施厌氧氨氧化（厌氧氨氧化）将导致氨和亚硝酸盐（两者对水生动物都有毒）转化为无害的氮气。海水和淡水水产养殖系统都含有厌氧氨氧化细菌。这些细菌也存在于淡水和海水鱼的粪便中。有趣的是，似乎在这些再循环系统中也存在一种新的浮霉菌物种。进一步开发水产养殖系统不同隔室中的厌氧氨氧化细菌可以实现更环保的水产养殖实践。
