Seines

**Seines**

A seine is a type of fishing net used primarily in both freshwater and saltwater environments. The net is typically rectangular or oval-shaped, with a long, tapered end known as the headrope, which is attached to a series of floats or buoys. The body of the seine consists of a mesh or netting material, while the footrope, at the bottom, is weighted to keep the net submerged. Seines are often deployed in a way that encircles schools of fish, trapping them within the net before they can escape.

There are several variations of seines, including gill seines, trawl seines, and purse seines. Gill seines are used to catch fish by trapping them in the mesh, while trawl seines are dragged through the water to scoop up fish. Purse seines are used in open waters, where the net is lowered into the water and then closed at the bottom to trap fish within.

Seines have been used for centuries and remain a vital method of commercial fishing. They are particularly effective in capturing large quantities of fish, such as herring, salmon, and tuna. However, their use has also raised concerns about environmental impacts, including bycatch of non-target species and potential harm to marine ecosystems.

Modern seines are often equipped with advanced materials and designs to improve efficiency and reduce environmental harm. Despite these advancements, ongoing research and regulation aim to balance the need for sustainable fishing practices with the economic importance of seine fishing.
