State-of-the-art Fisheries Intelligence
from the World’s No. 1 FMC Provider

Get more from your data, all in one place.


THEMIS is a comprehensive fisheries management software suite for administrations and fleet managers. In addition to VMS tracks, Themis manages the entire database of ships and all their information (such as identifiers, vessel name and characteristics, owner name, and licenses). It provides everything you need for combatting illegal fishing (IUU), monitoring fishing efforts and zones, and protecting stocks.


Instead of simply showing vessel monitoring tracks, THEMIS integrates all the information you need on one map. For example, clicking on a ship links to its catch reports, so you can easily compare the logbook details with the vessel’s tracks and time spent fishing. Better analysis, better decision-making, made easy.
