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 is a heatmap showing where the catch of the active demersal fleets is more dense or less dense.

Active demersal 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 active demersal fleet]]. | |||
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) | |||
