Snap rings or purse rings



Snap rings or purse rings

The snap ring or purse seine ring is a piece of rigging hardware essential for purse seine or sardine fishing. These vessels hunt for large fish like tuna, salmon, sardines and mackerel.

The seine is the large net (up to 50 hectares for large oceanic tuna freezer boats) that is placed in the water, surrounds the shoal of fish then closes around it, enclosing it in a huge pocket in which sailors collect the fish along the length of the boat.

Snap rings or purse seine rings are circular or oval-shaped and can be highly sophisticated on some oceanic tuna seines. They slide along the steel wire rope, known as the pursing wire, on the lower rope of the seine, enabling the seine to be closed to capture the fish. On board, the snap rings are placed back on the rack.

Did you know? Ring in Spanish is cancamo. In French it’s called a margouillet or anneau de senne.
