Purse seiners are the most important and most effective vessels to catch aggregating species near the surface. The vessel surrounds the shoal with a deep curtain of netting and then the bottom of the net is pursed (closed) underneath the shoal by hauling a wire which runs from the vessel through rings on the bottom of the net and back to the vessel. Searching for shoals and assessing the size and direction of movement of it are the most important part of the fishing operation

Equipment Deck Equipment Typical equipment of purse seiners consists usually of a power block or triple roller (triplex) and storage equipment for hauling and stowing the net aboard. On larger vessels the fish is pumped on board while on smaller vessels the use of brailers is more common. On boats using small seine nets all operations are generally performed by hand.

Fish Detection Equipment On the more advanced purse seiners electronic equipment such as different types of echo sounders and sonar, and track plotters are used to: support the search for schools; assess the size and movement of the school; and to keep in touch with the school whilst surrounding it with the seine.
