Yellowtail, a warm-flowing fish, is mainly caught in the southern coast and Jeju Island, but recently, it has also been caught a lot in the east coast. This is because the water temperature has risen due to climate change.



Reporter Jae-geun Cho visited the field of defense fishing in season.

Gain Port, Goseong-gun, Gangwon-do.



Breaking through the darkness, the fishing boat arrives at the fishing ground 30 minutes after it has left the port.



When the pre-set net is pulled up using a crane, a large shoal of fish flaps and creates a splash of water.



It has a blue back and a silver belly.



They range from as small as 30-40 cm in size to close to 1 m in size.



Each shed that holds the fish you catch quickly fills up with a large defense.



This is the defense I caught today (27th).



Although it is relatively small, weighing only 3 kg, it is traded for about 50,000 won.



The daily catch varies widely depending on the route, timing, and sea conditions of the defensive flock.



[Lee Jong-beom/Captain Bukyang Fisheries: When a lot is caught, about 10 tons or less are caught, and when there are not, about 1 ton is caught. (When you catch a lot) Once you store it in the sea, and when the amount runs out, you bring it back little by little (sell it.)] In the



east coast of Gangwon-do, about 2,900 tons of yellowtail were caught this year, and the catch has increased by more than 5 times compared to 10 years ago.



In particular, the catches of Gangwon Province exceeded that of Jeju Island seven years ago.



Yellowtail, a migratory fish, is caught moving northward in early summer and moving southward in late autumn.



[Jung-Jin Kim/Dr., National Fisheries Science Institute: As the water temperature around Korea increased for a long time, the amount of resources of the warm-flowing fish species of yellowtail increased. In particular, the distribution area of ​​yellowtail has recently moved north due to the formation of high temperatures in the summer (the catch of Gangwon-do has increased)] The increase in



water temperature Defensive hunting on the east coast of Gangwon-do, which has emerged as a major production center for defense, will continue until the beginning of next month.
