Preliminary assessment of glass eel (Anguilla spp.) fishery in Santa Ana, cagayan

Abstract

The study assessed the fishing grounds for glass eels (Anguilla spp.) in Santa Ana, Cagayan, Philippines, focusing on fishing gears, fishing effort, and policy recommendations for eel stock enhancement. Conducted from March to May in the Palawig and Diora-Zinungan Rivers, both critical migratory routes for catadromous fishes, the research employed a mixed methods approach, integrating qualitative observations and interviews with quantitative data collection. Results indicated favorable environmental conditions in both rivers for glass eels, with minimal variation in their length and weight. Catch data revealed higher glass eel abundance in the Palawig River, with Anguilla marmorata as the dominant species. The findings underscored concerns regarding the sustainability of glass eel fishing, emphasizing the need for conservation measures. The study recommended stock enhancement research, aquaculture initiatives, increased research investment, and awareness campaigns to ensure the long-term sustainability of glass eel populations and the ecological integrity of their habitats.
