This utility model relates to a real-time Fishing Activity Monitoring System that integrates Internet of Things (IoT) technology, Geographic Information Systems (GIS), and weather data through web and mobile applications to enhance fisheries management. The system comprises IoT-enabled monitoring devices installed on fishing vessels, equipped with GSM and GPS modules to transmit geolocation and catch data to a central server. This server aggregates the data with external weather API inputs to generate spatial heatmaps and fishing insights. A mobile application allows Fish Landing Officers to log fish species and volume, access weather conditions, and track boats in real-time. A web-based GIS interface displays polygonal fishing zones, boat paths, and environmental overlays. The integrated analytics dashboard visualizes fish migration trends, catch frequency, and weather influence. The system improves monitoring accuracy, supports timely decision-making, and promotes sustainable fishing practices through a data-driven and locationaware platform.
