The anthropogenic activities that attribute to the condition of the river was conducted. Physico-chemical parameters of water that include turbidity, temperature, total dissolved solids (TDS), pH, dissolved oxygen (DO), biological oxygen demand (BOD), nitrates, and phosphates—and biological properties like total coliform were analyzed. Based on the results, eight fish species was identified in Ubihan River. Mayaheros urophthalmus and Sarotherodon melanotheron, both from the Cichlidae family, were the most abundant, while Eleotris melanosoma from the Gobiidae family was the least abundant. Statistical analysis revealed significant temporal variations in water quality parameters, though spatial differences across the sites were less pronounced. High coliform counts suggest contamination from sewage and runoff, posing risks to human and aquatic life. The Shannon-Wiener and Simpson’s diversity indices confirmed a diverse ichthyofaunal species in the Ubihan River, despite the environmental stressors. The correlation between poor water quality and reduced species diversity underscores the need for targeted conservation efforts. The research contributes valuable insights into freshwater biodiversity conservation in the Philippines, emphasizing the urgent need to address anthropogenic impacts on vulnerable aquatic habitats.
