  Information and understanding of fishing activities at sea are fundamental
components of marine knowledge and maritime situational awareness. Such
information is important to fisheries science, public authorities and policy
makers. In this paper we introduce a first map at European scale of EU fishing
activities extracted using Automatic Identification System (AIS) ship tracking
data. The resulting map is a density of points that identify fishing
activities. A measure of the reliability of such information is also presented
as a map of coverage reception capabilities.
