Description:
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.

Type Overview:
Fishing Type Impact:
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 |
| Benthic | 0,112 |
| Cetaceans | N/A |
Fishing Type Flow Diagram:
The following diagrams show the impact of different Fishing Fleets on ecology. The different types can protect against the impacts of the indicated fleets.
