The Fisheries Resources Research Institute began releasing juvenile ark shells with about 300,000 in July 2019, followed by about 500,000 in July 2021, and another 500,000 last July. Including this year's release, a total of approximately 1.7 million juvenile ark shells are expected to have been released.
Since 2020, the Fisheries Resources Research Institute has been observing the water quality and sediment environment of the ark shell habitat in Cheonsuman quarterly to enhance the effectiveness of the releases. This year, environmental surveys were conducted twice in the first half of the year.
The results of the environmental surveys are utilized for selecting optimal release locations and for research on resource recovery technology development for ark shell aquaculture farms, a project under the National Institute of Fisheries Science's research and training fishery farm program.
