The Gyeongnam Provincial Fisheries Research Institute in South Korea has released 300,000 young sea cucumbers into six fishing villages, with a plan to release an additional 400,000 in mid-December. These sea cucumbers, weighing around 1-3g, were raised for seven months and were previously purchased as fertilized eggs from the Najam fishery in Tongyeong. The institute has industrialized a technology for mass production of sea cucumber seeds, which was previously reliant on Chinese technicians, and produces about 600,000 healthy seeds annually. The release of sea cucumbers aims to improve water quality by consuming organic matter on the seabed.
