Abstract:  Realtime monitoring for long time has an important role on aquaculture water quality, shrimp farming is developed based on the BDS of mobile intelligent feeding system in this paper, According to the characteristics of shrimp farming,we select dissolved oxygen, PH, temperature, electrical conductivity for realtime online detection of water quality parameters. Through the data acquisition part of the water quality parameters of HaTang realtime information, then through the control parameters in the process of expert system of intelligent judgment bait casting, achieve precise and effective feeding.
