Description[edit | edit source]

Bottom trawling is trawling (towing a trawl, which is a fishing net) along the sea floor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone.

Fishing Type Impact[edit | edit source]

The following table indicates the t/km2 catch on the basic settings of the game. Increasing or decreasing the fishing effort will result in increased impact on the following groups.

Group name t/km2
Flatfish 0,675
Cod 0,119
Demersal 0,072
Sandeel 0,000
Herring 0,002
Mackerel 0,008
