Seine fishing (or seine-haul fishing; / s eɪ n / SAYN) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat.
The purse seine is an example of a surrounding net. Here any salmon swimming near the surface are surrounded with a wall of netting, supported by floats. A surrounding net is a fishing net which surrounds fish and other aquatic animals on the sides and underneath. It is typically used by commercial fishers, and pulled along the surface of the ...
The Puretic power block revolutionized the technology of hauling fishing nets, particularly purse seine nets. According to the Food and Agriculture Organization of the United Nations (FAO) , "no single invention has contributed more to the success of purse seine net hauling" than the power block, which was "the linch-pin in the mechanization of ...
The purse seine, widely used by commercial fishermen, is an evolution of the surround net, which in turn is an evolution of the seine net. A large net is used to surround fish, typically an entire fish school, on all sides. The bottom of the net is then closed by pulling a line arranged like a drawstring used to close the mouth of a purse.

Researchers commented that the use of recovery ...

The history of "purse-seine" net fishing for yellowfin tuna has been the preferred fishing technology of choice for many parts of the world over the last three decades. This type of fishing involves the use of two boats, the primary fishing vessel, and the "seine skiff" motorboat.
Either is acceptable. "Seine" by itself can refer more to the technique. But if the context is clear, then "seine" can equally refer to the net. The FAO article on the nets is titled "Seine nets", not "Seines". And that is about definitive as you can get in fishing. But in the body of their article they sometimes refer to the nets simply as ...
