An advanced reporting system that electronically reports, processes, stores and sends fisheries data to fishery managers and authorities. The key element of an ERS is an electronic logbook, in place of traditional paper logbooks, where the master of a fishing vessel keeps a record of fishing operations (catches, landings, sales, transshipments, etc.). Vessels with ERS are equipped with a transmitter programmed to send these data periodically together with information on the position of the vessel.
