Passive Demersal Catch

Sub-category	Fishing

Description

The passive demersal catch is a heatmap showing where the catch of the passive demersal fleets is more dense or less dense. The fleets considered as passive demersal are the ones using fixed or drift nets on or close to the sea floor.

MSP Challenge

The passive demersal catch does not contribute to the pressure calculations but does affect the species that are catched by this fleet.

Not applicable.

This layer is not available in the North Sea Edition.

This layer cover the Baltic Proper area only.

In the Baltic Sea, the passive demersal fleets catch mostly:

• cod (adults)
• herring

Types

• Very low density
• Low density
• Medium density
• High density
• Very high density

Data Source

The passive 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.
