USING SATELLITE TECHNOLOGY IMPROVE CHILEAN PURSEINE FISHING FLEET

A work of gathering historical fishing (catch, fishing effort, CPUE, characteristics and operation of purseiner fleet) and satellite (NOAA, SeaStar and SeaWind) database of northern Chile, and fishing and oceanographic in situ sampling for validation purpose is made. With this information and the us...
