Peru uses VMS to manage its anchovy fishery. For Peru fishing is a prime source of foreign exchange, second only to mining. Over 1000 fishing vessels are tracked in Peruvian waters by Argos. The Peruvian government implemented a national fishing Vessel Monitoring System (VMS) in 1998 to monitor and track all fishing vessels in its Exclusive Economic Zone. One of the first major VMS system's in the world, the system continues to operate today and is a reference for other countries wishing to implement similar fisheries management capabilities.
