Changwon Special City, in partnership with the Gyeongnam Provincial Fisheries Resources Research Institute and local fishermen, has released 1.5 million young cod fish into Jamdo waters to boost cod resources. The cod larvae were artificially inseminated and hatched at the research institute. Additionally, the city has been running the Daegu Fertilized Egg Release Project since 2006 to sustain Daegu resources, a winter specialty product. This year, 77 million artificially fertilized eggs were produced and released into local waters.
