Description
Technical Field
[0001] The present invention relates to the technical field of water quality monitoring, and more particularly to a water quality monitoring and management system and method for fishery aquaculture. Background Art
[0002] During the process of fishery aquaculture, a large amount of sewage, dirty water and wastewater are generated. These water bodies usually contain biological excreta, feeding residues, microorganisms and other harmful substances. If these pollutants are discharged into the natural environment without proper treatment, they will have a serious impact on the fishery water ecosystem, including water quality deterioration, death of aquatic organisms, destruction of ecological balance, etc. In addition, with the expansion of the scale of fishery aquaculture and the improvement of intensification, the problem of water pollution has become increasingly prominent and has become one of the key factors restricting the sustainable development of fishery.
[0003] With the continuous development of technologies such as the Internet of Things, big data, and artificial intelligence, the management of water pollution in fishery aquaculture has become more intelligent and information-based. By using modern scientific and technological means, such as big data technology and intelligent devices, the establishment of a real-time monitoring and early warning system for aquaculture water bodies has effectively reduced water pollution during the aquaculture process, improved the utilization efficiency of water resources, and can timely detect and handle water pollution problems, providing strong technical support for the management of aquaculture water pollution.
[0004] However, common real-time monitoring and early warning systems for aquaculture water bodies often judge the water quality status by monitoring the compound content in the aquaculture water body. Although this method is intuitive, it ignores the influence of environmental factors on water quality. On the other hand, using hyperspectral imaging technology can understand the water quality status more comprehensively than traditional compound monitoring, thereby improving the accuracy and precision of monitoring to a certain extent.
