Purse seine fishing is a fishing method that involves surrounding a school of fish with a net and then closing the net at the bottom to prevent the fish from escaping. The success rate of purse seine operations is universally determined by the trajectory of the net shooting whether in large-scale, offshore, or coastal purse seine operations. The decision on where to shoot the nets and the movement of the surrounding vessels depends on the captain's or fishing master's judgment that is based on experience. Real purse seine operations must consider wind direction, currents, wave height, and the distribution of prey and other marine life making it challenging to cast a perfect circle or oval-shaped net, often relying on various shooting trajectories based on experience. Current purse seine operations involve both the main vessel and auxiliary boats, and the shooting trajectory is determined by various environmental factors like wind direction and sea conditions making it challenging to achieve a perfect cast. This comprehensive overview of the purse seine fishing industry and its practices in South Korea provides insights into the operational techniques and challenges faced by fishermen as well as the significant role of research in enhancing fishing operations and sustainability.
