A Vessel Monitoring System (VMS) is an integral component of modern fisheries management. It is a system designed to continuously monitor and provide information about the location, course, and speed of fishing vessels. This is done through tracking devices, known as VMS units, installed on board vessels. These devices relay data via satellite and/or GSM networks to a central system, the Fishing Monitoring Centre (FMC) software, which processes and visualizes the data for regulatory authorities and fisheries managers. Beyond its core functionality of monitoring vessel location and activities, a VMS serves several crucial purposes. It helps ensure that fishing activities remain within designated areas and adhere to established rules and regulations, thus promoting sustainable fishing practices. Additionally, it aids in the enforcement of fisheries laws, facilitating quick response in case of violations. Importantly, a VMS also enhances safety at sea by allowing for real-time vessel tracking and swift response during emergencies, with some units equipped with panic buttons for immediate alert signaling. VMS can further be integrated with other systems, such as Electronic Logbooks (E-logbook) and Electronic Reporting Systems (ERS), providing a comprehensive solution for fisheries management. This combined system then serves as a vital tool for informed decision-making, helping maintain the health of fisheries and secure the long-term sustainability of marine resources.
