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. @Wikipedia
MSP Challenge 2050:
Within the MSP Challenge Game the Natura2000 areas are protected areas used to fully protect, or indicate protection, against specific ecological impacts, including;
- Fishing Fleets
- Shipping
- Wind Turbines
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 | Bottom Trawl | Industrial Trawl | Drift and Fixed Nets | |
---|---|---|---|---|
Flatfish | 0,675 | 0,001 | 0,008 | |
Cod | 0,119 | 0,003 | ||
Demersal | 0,072 | 0,003 | ||
Sandeel | 0,000 | 0,000 | ||
Herring | 0,002 | 0,000 | ||
Mackerel | 0,008 | 0,210 | 0,001 | |
Benthic | 0,112 | 0,010 | 0,000 | |
