Diivanivõrkudest

Diivanivõrkudest, also known as divan nets, are a type of fishing gear used primarily for catching flatfish such as flounder, plaice, and sole. The term "diivanivõrk" is derived from the Estonian words "diivan" meaning "divan" or "sofa," and "võrk" meaning "net." This gear consists of a net that is towed behind a boat, with a series of floats attached to the top of the net to keep it suspended just below the water surface. The floats are typically made of buoyant material such as plastic or foam, and are spaced evenly along the net to create a series of "windows" or "eyes" that allow the net to move freely through the water.

The diivanivõrk is designed to be selective, targeting only flatfish while allowing other species to escape. This is achieved through the use of a mesh size that is smaller than the size of the target species, but larger than the size of the other species that are not targeted. The net is typically made of a strong, durable material such as nylon or polyester, and is designed to be lightweight and easy to handle.

Diivanivõrkudest is commonly used in coastal and estuarine waters, where flatfish are abundant. The gear is typically towed at a slow speed, allowing the net to move through the water and capture the target species. The net is then brought back to the boat, where the catch is sorted and the target species are removed. The non-target species are then released back into the water.

In recent years, there has been growing concern about the impact of diivanivõrkudest on non-target species and the marine environment. As a result, there has been a push to develop more sustainable and environmentally friendly fishing practices, including the use of alternative fishing gear such as trawls and longlines. Despite these concerns, diivanivõrkudest remains a popular and effective method for targeting flatfish in many parts of the world.
