- Fishing - Spatial distribution of fishing activity both inshore and offshore - Bottom trawl effort - raster, WGS84
In the study area (around Kephalonia island), primary VMS data for the year 2014 ανδ fishing vessels larger than 12 meters in total length provided by the Hellenic Ministry of Mercantile Marine and Island Policy were used to estimate the fishing effort expressed in number of fishing days by gross tonnage (days at sea * GT).

- Supplemental Information
- For trawlers, it was assumed that VMS readings of speed between 0 to 4 knots correspond to “fishing”, while speeds greater than 4 knots correspond to “steaming”; vessel positions in or close to harbours were excluded. In general, trawlers operated in the north-western and eastern territories of Lefkada island, east of Kefalonia and Zakynthos islands, inside Patraikos Gulf and in the northern part of Korinthiakos Gulf. The highest values of fishing effort were identified around the Astakos region, the outer part of Patraikos Gulf and the western part of Korinthiakos Gulf. The Trawler Fishing Effort (TFE) criterion was based on the intensity of trawler fishing effort. Ranking was based on four defined classes, under the assumption that coastal fishing pressure should be low when TFE is high.
