Jeju Island, pushing for mixed-species aquaculture in response to high temperatures

As damage from high water temperatures continues due to climate change, Jeju's aquaculture industry is seeking new solutions. The Jeju Marine and Fisheries Research Institute announced on the 8th that it is embarking on a pilot study for mixed-species aquaculture using long-tailed red snapper and black porgy, species native to Jeju waters, to reduce damage from high water temperatures due to climate change. This response measure has been developed as the need for developing alternative aquaculture species that are resistant to high water temperatures has increased, following continued damage to mackerel farms during the recent summer heatwave. Currently, mackerel is the main aquaculture species in Jeju, accounting for the highest percentage. In the eastern region, where underground seawater has been developed, the use of rainbow trout as a substitute for mackerel is increasing, and some farms are also cultivating turbot.
