A surround net fishing method used in small‑ or medium‑size vessels, which is believed to be the precursor of the purse seine. Similarly to purse seining operations, once the fish are encircled by the net, a pursing line that passes through the rings at the lower edge is used to close the bottom. The ring net has wings and a central bunt with smaller mesh in which the capture concentrates as the wings are hauled together. The catch is transferred onboard from the bunt using a scoop net.
This type of fishing method is very commonly used by small‑ and medium‑size boats in tropical tuna fisheries in the Indo-Pacific.
