Busan Gijang-gun Releases 60,000 Self-Produced 'Cheonghae Samjongja' into Village Fishing Grounds

Korea Hydro & Nuclear Power Operator Support Project... Concurrent Test Research on Red Sea Cucumber Seed Production

Busan Gijang-gun (Governor Jeong Jong-bok) announced that from the 3rd to the 4th, 60,000 juveniles of blue sea cucumber produced by the Gijang-gun Fisheries Resources Research Center were released into 14 village fishing grounds.

Since first succeeding in producing blue sea cucumber juveniles in 2020, the research center has continuously conducted research every year. In May, they secured blue sea cucumber broodstock inhabiting the coastal waters of Gijang-gun, performed artificial fertilization, and through about six months of in-house cultivation management, successfully raised juveniles weighing over 1g suitable for release.

Especially this year, reflecting the opinions of local fishermen, they received 20 million KRW in project funding from Korea Hydro & Nuclear Power Gori Nuclear Power Headquarters to concurrently conduct experimental research on red sea cucumber juvenile production. Using the blue sea cucumber juvenile production technology, they also began research on red sea cucumber juvenile production this year and produced approximately 450 red sea cucumber juveniles.

Sea cucumbers distributed in Korea are known as spiny sea cucumbers and can be classified into blue sea cucumber, red sea cucumber, and black sea cucumber according to body color. Their habitats and habits differ slightly, resulting in some differences in juvenile production technology.

Sea cucumbers are distributed along all coasts of Korea and serve as decomposers by consuming organic matter in the sea. They are valuable marine organisms that play an important role in maintaining coastal ecosystems and improving the marine environment. Through this release into village fishing grounds, it is expected to greatly contribute not only to marine environmental improvement but also to increasing the income of local fishermen.

Governor Jeong Jong-bok stated, “Sea cucumbers are a popular species among local fishermen. We will do our best to contribute to maintaining a healthy coastal ecosystem and increasing the income of local fishermen through continuous juvenile production research and release.”
