Knowledge, Attitude, and Practice (KAP) surveys reveal that local respondents' understanding of coastal and marine resources is rooted in experiential learning. The community demonstrates a favorable disposition towards environmental conservation, recognizing the ecological and economic benefits provided by marine resources (Spearman's rho, rs=0.05). Future research should focus on monitoring sedimentation rates and heavy metal concentrations in water and sediment, particularly post-initiation of mining activities. Comparative temporal studies are recommended to evaluate sedimentation across dry and wet seasons. Additionally, socio-economic assessments should consider the mining company's willingness to invest in environmental sustainability. Policy recommendations include mandating the Protected Area Management Board (PAMB), in collaboration with DENR-MGB and DENR- EMB, to require semi-annual environmental monitoring reports from the mining company. It is imperative that the company obtains a Special Use Agreement in Protected Area (SAPA) despite holding a Mineral Production Sharing Agreement from DENR-MGB. Local Government Units (LGUs), in partnership with Barangay Local Government Units (BLGUs), should lead local enforcement efforts to ensure compliance with environmental regulations. This study assesses the environmental and socio-economic conditions surrounding Manicani Island in anticipation of future mining operations. The current sedimentation rates (0.052.490 mg cm^2 d^-1) are below the critical threshold for coral reefs (10 mg cm² d-'), suggesting minimal immediate sediment impact. Coral cover varies from poor to excellent, correlating positively with fish density (r=0.680) and biomass (r=0.640). Areas with higher fish densities also exhibited higher Catch Per Unit Effort (CPUE), though the catch predominantly comprised non-target species. Fisherfolk face challenges in catching desired fish species, necessitating extended effort and advanced gear. Parilla, Richard B. adviser. Thesis FI UP UPTAC UPTAC LG 995 2023 E5 P33 Thesis
