The invention discloses an aquaculture industry water environment intelligent monitoring system based on big data. The aquaculture industry water environment intelligent monitoring system comprises awater area division module, a sampling acquisition module, a water quality parameter detection module, a parameter preprocessing module, a manual input module, a parameter storage database, a water quality parameter analysis module, a management server, an oxygenation adjustment terminal and a display terminal. Aquaculture water body regions are divided, sampled and subjected to water quality detection through the water body region division module, the sampling acquisition module and the water quality parameter detection module, so that the accuracy of water quality detection is improved; thewater quality parameter analysis module is combined to analyze the detected water quality parameters; according to the method, quantitative display of the water quality of the aquaculture water body is achieved, managers can visually know the influence effect of the water quality on fish aquaculture, the appropriate aquaculture density is determined according to the water quality aquaculture suitability coefficient, an appropriate growth environment is provided for fish aquaculture, and the aquaculture quality of fishes is improved.
