Gyeonggi-do Marine and Fisheries Resources Research Institute Confirms Establishment of 'Beoldeulchi' Released into Gapyeong Stream

Release of Burbot into Gapyeong Stream

Gyeonggi Province confirmed that the Rhynchocypris oxycephalus (beodulchi) released into Gapyeong-gun last year has successfully settled.

The Gyeonggi Marine and Fisheries Resources Research Institute announced on the 18th that genetic analysis conducted last month on 40 beodulchi collected from Gapyeongcheon revealed that three of them were beodulchi released by the institute.

Earlier, in July last year, the institute released 5,000 beodulchi fry, produced in-house for the restoration of native freshwater fish, into the upper valley of Gapyeongcheon.

Since its establishment in 1989 as the Inland Water Development Testing Center, the institute has conducted seed production research on various inland water species such as sand goby and kuguri, and has trial-released the produced fry into rivers in Gyeonggi Province.

This is the first time the institute has researched and investigated whether the released beodulchi have settled well in natural streams, making it significant as the release effect has been objectively confirmed.

Starting with this beodulchi release effect study, the institute plans to continuously research the survival rate and ecological contribution of the release fry of Gyeonggi Province’s protected species, Miyugi, next year.

Beodulchi is a freshwater fish belonging to the family Cyprinidae in the order Cypriniformes, living in cold mountain streams or upper reaches of rivers, and is considered a first-class water quality indicator species.

Kim Bong-hyun, director of the Gyeonggi Marine and Fisheries Resources Research Institute, said, "While we have conducted effect surveys on releases aimed at resource enhancement such as crucian carp and Korean perch through surveys targeting fishermen, this is the first time we have investigated the natural settlement of beodulchi released for species conservation," adding, "Through this effect survey, we will strive for continuous management and species conservation research of freshwater fish sensitive to climate change, such as beodulchi."
