Description

Bottom trawling is trawling (towing a trawl, which is a fishing net) along the sea floor. It is also referred to as "dragging". Bottom trawling can be contrasted with midwater trawling (also known as pelagic trawling), where a net is towed higher in the water column. Trawling is done by a trawler, which can be a small open boat with only 30 hp (22 kW) or a large factory trawler with 10,000 hp (7,500 kW). Bottom trawling can be carried out by one trawler or by two trawlers fishing cooperatively (pair trawling).

MSP Challenge

Bottom Trawl Catch is a month-by-month, computer generated data layer following this fleet's fishing efforts calculated by the ecosystem simulation. This fleet doesn't fish in areas that are protected against bottom trawl.

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).

The Bottom Trawl fleet mostly catches the following species:


Types

  • Very Low Density
  • Low Density
  • Medium Density
  • High Density
  • Very High Density
