Uljugun Taehwagang Ecological Center Registers Two Patents for Yellow Corvina Parentage Verification Methods

Using Genetic Markers for Parentage Identification to Distinguish Wild and Released Hwangeo Fish

Ulsan Ulju-gun Taehwagang Ecological Center has registered two patents related to a parentage verification method that can distinguish between wild and released Korean dace.

Ulju-gun Taehwagang Ecological Center.

This patent registration was promoted as part of the ‘2023 Taehwagang Fisheries Habitat Status Survey Project,’ conducted by the Korea Fisheries Resources Agency entrusted by Ulsan City.

The patents include ‘Genetic markers for parent identification of Korean dace and a parentage verification method using them’ and ‘Genetic markers for parent identification of Korean dace and a parentage verification method for released seeds using them.’

Korean dace is an anadromous fish designated as a protected wild species by Ulsan City and is called the herald of spring in the Taehwagang River. Recently, due to climate warming and diversification of limited river spaces, the Korean dace resource has rapidly declined, necessitating systematic research on release and management.

By utilizing this patented technology, it is possible to distinguish between released juvenile Korean dace and wild Korean dace. It also enables estimation of the release year, location, growth status, return rate, and resource quantity of released Korean dace, which is expected to greatly aid in the efficient management and protection of Korean dace resources.

The Taehwagang Ecological Center plans to use this patented technology in the ‘2024 Taehwagang Released Organisms Pre- and Post-Release Survey Project’ to monitor the growth and return of released juvenile Korean dace.

Based on the monitoring results, the center intends to scientifically analyze the impact of Korean dace release on the Taehwagang River and surrounding ecosystems to establish more effective release strategies.

A representative of the Taehwagang Ecological Center stated, “This patented technology is the result of efforts for the sustainable management of Korean dace, a protected species of the national river Taehwagang, and the conservation of the Taehwagang ecosystem. We will contribute to the protection of local fishery resources through scientific analysis using new technology.”
