The active demersal catch is a heatmap showing where the catch of the active demersal fleets is more dense or less dense. The fleets considered as active demersal are the ones using trawling of nets on or close to the sea floor.
The active demersal catch does not contribute to the pressure calculations but does affect the species that are catched by this fleet.

This layer cover the Baltic Proper area and the Bothnian Sea area only.
In the Baltic Sea, the active demersal fleets catch mostly:
The active demersal catch data layer comes from the EwE model developed on purpose for MSP Challenge usage based on the model by Tomczak, M.T., Niiranen, S., Hjerne, O., Blenckner, T. (2012) with the invaluable contribution of Jeroen Steenbeek, Maciej Tomczak , Giovanni Romagnoni, Rikka Puntilla, Ville Karvinen and Magali Gonçalves.
