The study primarily aimed to determine the body shape variation of Hypseleotris agilis using Fluctuating Asymmetry (FA) in relation to their existing population in Lake Mainit, Surigao del Norte, Philippines. The research used Procrustes ANOVA and Principal Component Analysis (PCA) by means of Symmetry and Asymmetry in Geometric Data (SAGE) software to analyze the data. Finding reveals that Hypseleotris agilis’ individuals, sides, and individual x sides show high significant difference (P<0.0001). Females obtained high percentage of FA (83.0227%) while males have (76.3627%). It implies that females are vulnerable toward environmental alterations that could be manifested in its morphology. Further, utilizing Geometric Morphometric is essential in identifying morphological variations and co-variations of species in the same taxa.
