The Gyeonggi-do Marine and Fisheries Resources Research Institute released 35,000 fry of native fish species, including daesolgi, goldfish, and bitterlings, into the Tancheon River in Seongnam on the 2nd to restore fish resources and conserve biodiversity. The fry were produced by the institute through experimental research projects and have passed inspections for aquatic animal infectious diseases, ensuring they are healthy. Daesolgi and goldfish play foundational roles in the river and stream ecosystems, while bitterlings help reduce harmful insects in an eco-friendly manner by feeding on aquatic larvae. The institute chose the Tancheon River, a popular spot for many citizens, as the first release site to widely publicize the necessity and effectiveness of restoring native fish species.
