AIS may accidentally malfunction or be voluntary switched off. Nevertheless, it can highlight non-reporting vessels and be helpful to detect suspicious fishing activities especially when coupled with satellite imagery. In this context, a workflow is presented to integrate AIS and SAR data.

AIS use is steadily increasing and its utility in tracking fishing vessel activity is growing. In 2017, AIS was broadcast by approximately 60 000 fishing vessels of which just over 22 000 could be matched to publicly available vessel registries. This number is steadily increasing, and between 2014 and 2017, the number of vessels broadcasting.

Its key resource for detecting illegal, unreported, and unregulated (IUU) fishing is satellite automatic identification system (AIS) tracking data collected by Spire Global. And with sophisticated data analytics, the organization is revolutionizing how fishing activity is monitored.

For example, many vessels carry a device called an automatic identification system, or AIS, that automatically broadcasts the vessel's identity, position, course and speed. These devices communicate with other AIS devices nearby to improve situational.

AIS is a vessel-tracking system that automatically broadcasts information about a ship's position, course, speed, planned voyage and characteristics. The system can help identify security and compliance risks when suspicious behaviour at sea is highlighted by advanced analytics.. AIS signals are collected by equipment on vessels, land.

The strength of AIS Position Validation is that it independently calculates a vessel's location at the time of the AIS transmission, even if AIS messages do not include valid GPS data. This allows for the calculated position from the satellite data to be compared to the reported, and in some cases, fixed or out of footprint, positions.

Each AIS-equipped station (either a ship or shore facility) broadcasts and receives AIS messages to and from all stations within VHF radio range. To prevent transmissions from AIS-equipped ships and stations from interfering with each other, AIS uses a self-organizing time-division multiple access (SOTDMA) protocol to synchronize multiple data.

Even if monitoring systems such as AIS mainly concern legal persons (companies), they may also involve personal data, especially for fishing and leisure navigation (AIS B) activities, where a link can be made to the natural person owning the boat (European Commission, 2009). As a rule, the use of personal data requires consent from the natural.

Several research initiatives have been undertaken to map fishing effort at high spatial resolution using the Vessel Monitoring System (VMS). An alternative to the VMS is represented by the Automatic Identification System (AIS), which in the EU became compulsory in May 2014 for all fishing vessels of length above 15 meters. The aim of this paper is to assess the uptake of the AIS in the EU.
