Tangle Net

Tangle net fishing is a method of fishing that involves using a net with a very fine mesh to catch fish. Unlike traditional fishing nets that trap fish by entangling their gills, tangle nets are designed to catch fish by tangling them by their teeth, spines, or other protrusions. This method is particularly effective for catching species that are difficult to catch with other types of nets due to their size or the nature of their gills.

Overview[edit | edit source]

Tangle nets are a type of gillnet, but with a significant difference in the size of the mesh and the way they capture fish. The mesh size of a tangle net is usually smaller, and the net is often set in a way that it hangs in the water column or on the seabed. When fish attempt to pass through the net, they become entangled by parts of their body other than their gills. This method is considered less harmful to the fish if they are to be released, as it reduces the likelihood of damaging their gills.

Usage[edit | edit source]

Tangle nets are used in various fisheries around the world, targeting species such as flatfish, crab, and other bottom-dwelling species. They are particularly favored in artisanal and small-scale fisheries due to their simplicity and effectiveness. However, the use of tangle nets is regulated in many regions to prevent overfishing and reduce bycatch, which is the capture of non-target species.

Environmental Impact[edit | edit source]

The environmental impact of tangle net fishing is a subject of ongoing research and debate. On one hand, tangle nets can be seen as a selective and low-impact fishing method when used responsibly, due to their ability to catch target species without harming them significantly. On the other hand, if not managed properly, tangle nets can lead to significant bycatch, including juvenile fish and non-target species, which can have detrimental effects on marine ecosystems.

Regulations[edit | edit source]

Many countries and international bodies have implemented regulations regarding the use of tangle nets. These regulations may include limits on the size of the mesh, where and when the nets can be used, and what species can be targeted. The goal of these regulations is to ensure sustainable fishing practices that protect marine biodiversity.

Conclusion[edit | edit source]

Tangle net fishing is a method that, when used responsibly, can be part of sustainable fishing practices. However, it requires careful management and regulation to minimize its environmental impact, particularly concerning bycatch and the potential for overfishing.
