This study is a basic study for the management of major commercial fishing grounds in Korea. To this end, this study analyzed the types, characteristics and density distribution of sea-bed waste through a survey of bottom trawl in the seas around Jeju and Geomundo for 3 years from 2016, and investigated the relationship between the appearance of sea-bed waste and the fishing industry. A total of 966 sea-bed wastes were collected in the total survey area of 5.9km². Out of them 691(71.5%) were fish traps, followed by 86(8.9%) living wastes and 64(6.6%) long lines., 40(4.1%) nets, 47(4.9%) plastic garbage, 35(3.6%) ropes, and 3(0.3%) wire ropes. Among the collected fish traps, 57% were damaged in shape and the fishing catch ability was lost, while 43% of them were in good condition. About 40% of lost fish traps were found to have ghost fishing possibility. The amount density of sea-bed waste per unit area(km²) of the survey sea area ranged from a maximum of 220pcs/km² to a minimum of 80pcs/km² depending on the location, and the average of the total sea area was 150pcs/km². By type, fish trap was collected at the highest rate at 117pcs/km², followed by living waste at 15pcs/km², long line 11pcs/km², plastics at 8pcs/km², nets 7pcs/km², ropes 6pcs/km², etc. The sea area around Jeju and Geomundo are major fishing grounds for offshore fisheries in Korea. In the area, eels, blue crabs, yellow corbina, and sea breams are caught, and cross-fishing operations using fish traps, gill nets, and long lines are carried out throughout the year. Therefore, in this sea area, many fishing gears can not be lifted due to fishing accidents caused by competition among the fisheries and are often discarded underwater. Therefore, fishing gears such as fish traps, nets, and long lines, which occupy the majority of sea-bed waste collected, originate from the fishing operation conducted in this sea. Thus, the correlation can be considered very high. In particular, the fish trap, which shows the largest portion of the collected sea-bed waste, is made of synthetic resin, so the biodegradable time is long. As it may continue ghost fishing, it may adversely affect fishery resources. A reasonable way to solve this problem is to determine the location and scope of major domestic commercial fishing grounds in advance at the national level and proceed with the sea-bed waste collection in each sea area in sequence. In addition, it is necessary to reinforce fishermen"s responsibility by actively implementing a real-name fishing gear system to manage the history of fishing gear manufacturers, places of purchase, and disposal processes.
