Ask the Expert Luca Marsaglia Fisheries analyst, European Union What is the value of using research-derived datasets in analyses? Fisheries management is no simple task. The distribution of species, changes in productivity, management boundaries, illegal fishing and corruption are all factors that make oversight and governance of fisheries challenging. And the Mediterranean Sea is no exception. […]
Something we hear often about tracking vessels with Automatic Identification Signals (AIS) is that transponders can be turned off. Fishers that don’t want to be caught doing something illegal or questionable will simply “go dark.”
Latin American nation takes critical step forward in fisheries transparency, sharing vessel monitoring data on Global Fishing Watch Map
A partnership with Panama sheds light on the activities of one of the largest international fishing fleets, helping combat illegal fishing
Greater transparency needed to stop illegal fishing in the Mediterranean Members of the Med Sea Alliance, a diverse coalition of nonprofit organizations, today launched a new data atlas which, for the first-time, maps areas permanently closed to bottom trawling across the Mediterranean and investigates illegal trawling in these areas.

You can filter different data and each data has unique attributes that can be used for filtering. Some of the filters that can be found are: You can filter the apparent fishing effort by clicking on the filter icon in the Activity section. Depending on the source, you have different options: Automatic identification system (AIS) […]
The maritime Automatic Identification System (AIS) is a radio communications system by which vessels continuously broadcast their identity and position over public airwaves using unencrypted VHS radio signals. When it was developed almost 20 years ago, its primary purpose was to increase safety at sea: ships needed a better way to “see” each other and […]
