Description

The pelagic catch is a heatmap showing where the catch of the pelagic fleets is more dense or less dense. The fleets considered as pelagic are the ones operating in the water column.

MSP Challenge

Pelagic catch is a month-by-month, computer-generated data layer following this fleet's fishing catch calculated by the ecosystem simulation. This fleet doesn't fish in areas that are protected against pelagic catch.

A plan can also include a change in the fishing efforts for this fleet per EEZ. Activate the Fishing controls by ticking the appropriate checkbox under section 2b in the Plan Wizard. Subsequently, change the Fishing effort sliders under the Fishing tab of the Plan Details (maximize the Plans Monitor and select your plan)

Not applicable.

This layer is not available in the North Sea Edition.

This layer cover the Baltic Proper and Bothnian Sea area only.

In the Baltic Sea, the pelagic fleets catch mostly:

• sprat (mostly adults)
• herring
• cod (mostly juveniles)

Types

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

Data Source

The pelagic 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.
