Nitrogen biotransformation and its relative microorganism in aquaculture waters

摘要: 综述了国内外养殖水体N的生物转化及其相关微生物研究进展，指出养殖水体中N循环主要起源于所加入的配合饲料及有机或无机肥料，在生物和非生物共同作用下含氮化合物不断迁移转化，构成复杂的动态平衡，其中微生物起着关键作用，泥水界面层是有机物矿化和营养物质再生的重要场所。并提出渔业生产调控措施。

Abstract: The research results of nitrogen biotransformation and its relative microorganism in aquaculture waters are summarized. It is pointed out that nitrogen cycle in aquaculture waters mainly originates from the formulated feeds and the inorganic or organic fertilizers, which form complex dynamic balances through continuously transferring and transformation under interaction of organism and in-organism. Microorganisms play a key role in this cycle, the sediment-water interface is an important place of the mineralization of organic matter and regeneration of nutrition. Finally, some regulating practices are given that can influence the nitrogen cycle in the course of fish culture.
