Ekomorfologi Ikan Sembilang (Plotosus Canius) Di Kelurahan Concong Luar, Kecamatan Concong, Kabupaten Indragiri Hilir

This study analyzes the ecomorphology of the striped eel catfish (Plotosus canius) across three stations in the waters of Concong Luar to examine how environmental differences influence morphometric variation. Nineteen morphological characters were measured and analyzed using the Kruskal–Wallis test, Mann–Whitney test, and Principal Component Analysis (PCA). The Kruskal– Wallis results indicate significant differences among stations in several key characters, including BI, DBM, PFS, PJSDT, TBAA, PKL, and PKD. These variations reflect morphological adaptations to differing habitat conditions. Fish from Station 1, characterized by turbid waters and human activity, tended to have smaller bodieswithlarger eyes. Station2, influenced bypH and CO₂ levels, showed more developed head-related characters. Fish from Station 3, a more natural and faster-flowing environment, exhibited larger body sizes and longer, stronger fins. PCA further demonstrated that environmental factors such as turbidity, current velocity, pH, free CO₂, and salinity play major roles in shaping morphometric differences. Overall, the results show that P. canius exhibits strong morphological adaptation to estuarine habitat variation, highlighting the importance of habitat management and conservation efforts in Concong Luar.
Keywords: Ecomorphology, Plotosus canius, morphometrics, water quality, Concong Luar, morphological adaptation.
