bunntrål

Bunntrål is a method of fishing that involves dragging a weighted net across the seabed. This net, known as a bottom trawl, is designed to catch fish and shellfish that live on or near the ocean floor. The trawl is pulled by one or more boats, with the speed and depth of the trawl controlled by the fishermen.

The gear used in bunntrål varies depending on the target species and the seabed conditions. It typically includes a large net with a wide opening, often kept open by doors that spread the net apart as it is towed. Weights are attached to the lower edge of the net to ensure it stays on the seabed, while floats on the upper edge help keep it open.

Bunntrål is a widely used fishing technique globally, employed to catch a variety of species such as cod, haddock, flatfish, shrimp, and scallops. It can be an efficient method for catching large quantities of certain fish.

However, bunntrål has also been associated with environmental concerns. The dragging of the net can disturb and damage sensitive seabed habitats, including coral reefs and seagrass beds. This habitat destruction can have long-term negative impacts on marine ecosystems and biodiversity. Additionally, bunntrål can result in high levels of bycatch, where non-target species, including juvenile fish, marine mammals, and seabirds, are unintentionally caught in the nets. Efforts are ongoing to mitigate these impacts through regulations, gear modifications, and the establishment of marine protected areas.
