The National Academy of Fisheries Science, in partnership with the Oyster Underwater Fisheries Industry Cooperative and local oyster farmers, has created spawning grounds for mother oysters in six sea areas along the southern coast to address issues of delayed maturation and irregular spawning, potentially leading to a shortage of oyster seeds. This initiative, started in 2019, involves placing oysters and healthy mother oysters in chaerong nets or spraying them onto the sea floor, depending on the specific conditions of each area. The number of spawning grounds has been increased from five to six, with the addition to the Bongu area of Namhae-gun, aiming to boost the amount of oyster seeds collected this year. This project has been effective in reducing seedling costs through the accumulation of technology on efficient seeding methods.
