Isabela State University (ISU), through its Institute of Fisheries, continues to lead initiatives that promote sustainable aquaculture technologies designed to minimize environmental degradation and protect aquatic ecosystems. Reflecting ISU’s commitment to innovation and environmental stewardship, a undergraduate study that was completed last June 2024 by Mr. Glen Patrick V. Maddela, titled “Correlation of Productivity of Pangasius (Pangasianodon hypophthalmus)–Lettuce (Lactuca sativa) in Raft Aquaponics System and Its Water Quality,” serves as strong evidence of the university’s active engagement in eco-friendly aquaculture research.

Supervised by Dr. Mary Joy L. Asprec, Dean of the Institute of Fisheries, the study explored an integrated aquaponics system where fish and plants are co-cultured in a recirculating environment. Findings revealed that higher fish stocking densities improved water quality parameters such as nitrate and total ammonia nitrogen (TAN), while maintaining optimal pH, dissolved oxygen, and temperature levels. The system also enhanced the growth performance of Pangasius and the productivity of lettuce, proving that sustainable aquaculture can be both environmentally sound and economically viable.

The research concluded that aquaponics is a practical, resource-efficient, and eco-friendly technology that reduces wastewater discharge, minimizes nutrient pollution, and promotes responsible food production. It further recommends wider adoption of aquaponics among local fish farmers and communities as a sustainable approach to aquaculture.

This initiative aligns with Sustainable Development Goal (SDG) 14 – Life Below Water, as it directly supports the protection and sustainable use of aquatic resources. Through projects like this, Isabela State University reaffirms its dedication to research-driven solutions that advance food security, environmental protection, and the resilience of aquatic ecosystems.
