The estimation of derelict fishing gear in the coastal waters of South Korea: Trap and gill-net fisheries

• Estimation of the number of abandoned fish traps around the entire coastal areas of South Korea.
• Estimation of the number of abandoned gill-nets traps around the entire coastal areas of South Korea.
• Exploration of some feasible management solution for the problems of abandoned fish traps and gill-nets.

This study estimates the gross quantity of discarded fishing traps and gill-nets in the coastal waters of South Korea. Using regression analysis it is estimated that 11,436 t of traps and 38,535 t of gill-nets are abandoned annually. Experts on marine debris recommend replacement of traditional fishing gears with eco-friendly designs and establishment of incentive programmes for the fishermen in order to promote eco-friendly gear designs.
