A team of aquatic biologists and microbiologists led by Asst. Prof. Reuel Bennett, Dr.rer.nat., Chair of the Department of Biological Sciences, and Inst. Elfritzson Peralta, M.Sc., together with DBS academic staff Inst. Allan Gilles, M.Sc. and Inst. Eunice Aaron, M.Sc. (Marine Biology team), Inst. Justine De Leon, M.Sc. and Inst. Kenneth Xavier Sanchez, M.Sc. (Freshwater Biology team) conducted the study from August 11 to 14, 2024. The team covered 26 study sites in the watershed area, including mangrove forests, coastal areas, estuaries, streams, rivers, and a freshwater lake – Lake Danao. 

On September 17, 2024, Peralta, Assoc. Prof. Richard Thomas B. Pavia Jr., PhD, and Inst. Allan Gilles Jr., MSc presented the project’s initial results to Mayor Torres-Gomez. Also present were City Councilors Peter Rodriguez, Caren Torres Rama, Edmund Kierulf, and Bert Pades, together with officials from the City Environment and Natural Resources Office, City Agricultural Office, and representatives from the Protected Areas Management Board.

This initiative, which underscores the strong partnership between UST scientists and their government counterparts, is a testament to their shared commitment to bring science to the community.

Bennett delivered a lecture entitled “Oomycetes in Philippine freshwater ecosystems”, highlighting current research developments in taxonomy and potential utilization of oomycetes (aquatic fungi) for aquaculture as natural food source due to its potential for mass propagation and fatty acid content. Meanwhile, Papa updated the audience on “Methane Dynamics and Limnological Monitoring in Tropical East Asia: The Case of Lake Yambo”, which emphasized on the importance of routine limnological monitoring for water quality and methane concentrations in tropical lakes such as Lake Yambo as these are closely linked to eutrophication, especially in tropical lake ecosystems, especially those heavily utilized for aquaculture.

Papa and Bennett joined speakers from Korea, Japan, Taiwan, Turkiye, and Vietnam in giving lectures on the ecology and life history of economically important aquatic organisms, aquaculture, and fisheries, including topics on conservation, management, climate change adaptation and sustainability.

Chonnam National University holds the distinction of having the first and oldest fisheries and marine educational institution in South Korea and is known for receiving the most research funding among Korean universities.

Its College of Fisheries and Ocean Sciences maintains two research vessels, including the 96.45m ship Sae Dong Baek which was launched in 2019. Symposium speakers were given the opportunity to visit and inspect the research facilities of their two research vessels, which routinely conducts research cruises around the Korean peninsula.  A best research poster competition was also held during the symposium where graduate students and researchers of Chonnam National University showcased their latest research findings.

The event was organized by the CNU College of Fisheries and Ocean Sciences in cooperation with the Korea Fishery Resource Management Research Institute and the Institute of Fishing Village and Aquaculture.

Guinto, a Doctor of Philosophy in Biological Sciences student of the Graduate School, studied the freshwater calanoid copepod which was named an invasive species. Genomic DNA were extracted to represent seven populations in Luzon. The noted population increase is attributed to “the suspected initial introduction via ornamental aquarium fish trade practices in 1905 and then a population range expansion through a single or multiple introduction event towards other nearby inland waters through accidental movement of A. dorsalis individuals via human-mediated activities, particularly aquaculture, which have persisted since 1972.”
