摘要
在水产养殖过程中,过高的饲料蛋白水平会导致鱼类排泄物含氮量高,促进水体富营养化,导致水体严重污染。目前氨氮对水体的污染及其对鱼类的毒性受到广泛关注,但关于鱼类内源氨的代谢机制及其营养调控措施的研究尚未见报道。文章综述了鱼类内源氨的产生和耐受机制,并分析了营养调控对内源氨代谢的影响,以期为减少水环境中氨的浓度和提高鱼类的生长性能提供理论依据,对水生动物健康及水环境的保护具有重要意义。
In the process of aquaculture,too high protein level of feed will lead to high nitrogen content in fish excreta,eutrophication of water body,and serious water pollution.However,the metabolic mechanism of endogenous ammonia and its nutritional regulation measures have not been reported.Therefore,this paper summarized the production mechanism of fish endogenous ammonia,ammonia-tolerance strategy,and the corresponding nutritional regulation measures of reducing ammonia emission,which is of great significance to aquatic animal health and will provide a theoretical basis for reducing the concentration of ammonia in the water environment and improving the growth performance of fish.
