The National Institute of Fisheries Science is starting a cage test aquaculture for Benjari, a high-temperature resistant variety, in response to the increasing deaths of major aquaculture varieties on the southern coast due to high temperatures. Benjari is resistant to environmental changes and the institute is conducting research on its habitat environment, breeding control, and seed production. A business agreement has been signed with the Gyeongnam Provincial Fisheries Resources Research Institute for the industrialization of Benjari, and tests are being conducted to analyze its breeding possibilities in high water temperatures and winter, growth, health status, and aquaculture management.
