Pukyong National University, Develops the First Domestic Fish Stock Quantification Method Based on eDNA
-Professor Kim Kyung-hwe’s Research Team Publishes Findings in International Academic Journal
Pukyong National University (President Bae Sang-hoon) announced that Professor Kim Kyung-hwe’s (Department of Ocean Engineering) research team has developed the first domestic fish stock quantification method based on eDNA.
Professor Kim Kyung-hwe from the Department of Ocean Engineering at Pukyong National University, along with Ph.D. candidate Park Seong-sik and Dr. Yoon Seok-jin from the National Fisheries Research and Development Institute, conducted a numerical study on evaluating fish population and distribution in semi-enclosed bays using the environmental DNA (eDNA) approach.
eDNA is an innovative method that uses genetic traces of organisms to extract ecological information, and it is considered more efficient and non-invasive compared to traditional survey methods.
In this study, the research team analyzed the impact of environmental factors such as water temperature and currents on the distribution and concentration of eDNA through numerical modeling, and assessed the accuracy of the eDNA approach in estimating fish distribution.
Through this study, the research team not only demonstrated that the eDNA-based approach is a useful tool for estimating fish stock in semi-enclosed bays, but also presented new possibilities for fisheries and marine ecosystem management.
The paper titled ‘Numerical Study on Evaluation of Environmental DNA Approach for Estimating Fish Abundance and Distribution in Semi-Enclosed Bay’ has recently been published in the SCIE international journal <Journal of Marine Science and Engineering>
