To fulfill the needs of fishing ground forecasting system of domestic fishery companies, a fishing ground forecasting system is developed based on near real-time remote sensing data. The system has two modules, the land data service module and the fishing ground forecasting software module. The land service module is responsible for collecting the global near real-time marine environment data and providing the environmental data downloading service. The fishing ground forecasting software module can download the marine environment data from the land server and use the data to forecast the fishing ground using the habitat suitability index model. The system uses the International Maritime Satellite broadband services as data transmission channel. Former application tests of deep-sea fishing vessels indicated that the system can download the environmental data stably and calculate the potential fishing ground, which is important auxiliary information for fishing decision and can be used as a reference for fishing location selection.
