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
