Xinjiang region is characterized by large temperature difference between day and night,arid climate,lack of freshwater resources and abundant saline and alkaline water resources.Compared with freshwater fish farming,Oreochromis niloticus farming in saline and alkaline water can improve the utilization rate of water resources and expand the channels of water resources utilization.With the development of saline water aquaculture technology year by year,saline water aquaculture mode and technology suitable for Xinjiang region have been formed,and combined with the efficient utilization of aquaculture water technology,it can better promote the development of saline water aquaculture and planting industry.Therefore,this paper analyzes and summarizes the main points of water efficient use of O.niloticus aquaculture technology,aiming to promote the common development of"fishery-plantation"in saline areas,and provide reference basis for the efficient use of water resources,ecological restoration and protection of saline environment.
