trålnätet

Trålnätet refers to a fishing technique that utilizes a trawl net. This type of net is towed behind a vessel or a team of vessels, dragging across the seabed or through the water column to catch fish. Trawling is a widely used method in commercial fishing due to its efficiency in catching large quantities of fish.

There are several types of trawling, broadly categorized into bottom trawling and pelagic trawling. Bottom trawling involves dragging the net along the seafloor, which can impact benthic habitats. Pelagic trawling, on the other hand, occurs in the open water column, away from the seabed. Different designs of trawl nets exist to target specific species and fishing depths, often incorporating features like otter boards or weights to keep the net open.

The effectiveness of trålnätet comes from its ability to cover large areas and its relatively low labor requirement once deployed. However, concerns have been raised about the environmental impact of trawling, including bycatch of non-target species and damage to marine ecosystems. Regulations and management measures are often in place to mitigate these impacts and ensure the sustainability of fisheries employing this method. Research continues into developing more selective and environmentally friendly trawl gear.
