SLSU–San Juan Faculty Presents Catch Assessment Study at 2025 Inter-Agency RDE Review

Ms. Catherine G. Patual, faculty member of Southern Leyte State University–San Juan Campus, presented the study “Catch Assessment of Marine Fishes in Cabalian Bay, Philippines: Composition, Abundance, Gear, and Catch Rate” during the Cluster I Level 2 Inter-Agency Research, Development, and Extension (RDE) Review held on July 29–30, 2025, at Visayas State University.

Co-authored by Jackylou Sarsale, Marilou B. Siega, and Anna Marie Sarsale, the study assessed species composition, fishing gear types, and catch per unit effort (CPUE) at three landing sites in Cabalian Bay. Results showed a high level of species richness, with 31 fish families contributing to local fisheries productivity. Carangidae and Scombridae were identified as the dominant catch groups.

Among the sites studied, Pong-oy recorded the highest total catch, while Osao reported the most Scombridae catches. Seasonal peaks in August, December, and January were observed, indicating the influence of environmental factors on fish availability. The study also highlighted the use of various fishing gears, with handlining—particularly pasol—emerging as the most widely used method, contributing to the greatest catch diversity. Notably, tawa achieved the highest CPUE in Pong-oy during July, reaching nearly 20 kilograms per effort. Gill nets (pukot) also yielded high CPUE in August and January.

The researchers recommended more frequent sampling, inclusion of fish biometric data, and a longer study period to improve monitoring and support sustainable fisheries management. They emphasized the need to address environmental pressures and seasonal fluctuations affecting fish stocks in the bay.

SLSU–San Juan Campus’ participation in the inter-agency review underscores the university’s commitment to research-driven environmental conservation and sustainable resource use.

The study supports Sustainable Development Goals (SDGs) No. 2 (Zero Hunger), No. 12 (Responsible Consumption and Production), No. 13 (Climate Action), and No. 14 (Life Below Water).
