<p>A purse ring for coupling a purse seine and a purse line to each other. The purse ring includes a frame, which is coupled at a first end thereof to the purse seine and passes the purse line through a second end thereof, and at least three rollers, which are rotatably provided in the frame at positions at which the purse line are brought into contact with the frame. The purse seine having the multiple rollers has a structure such that friction between the purse line and the purse ring is reduced, thus increasing the lifetime of the purse ring, thereby reducing costs of replacement of the purse ring.</p> |
