Study on morphometric variations of halfbeak fish (Zenarchopterus buffonis Valenciennes, 1847) from estuary of West Sumatra has been conducted from December 2013 to April 2014. The fish samples were collected from four locations i.e. Batang Tarusan (Pesisir Selatan), Batang Antokan (Agam), Batang Basampan (Padang Pariaman), and Sungai Pisang (Padang). A total of 22 characters of morphometric and 8 characters of meristic were measured and calculated in this study. The data were subjected to the Kruskal Wallis analysis and continued with Mann Whitney test, Principal Component Analysis, and Unweighted Pair Group Method Average Arithmetic. The result showed that 18 characters have high variation. Those characters were Total length (TL), Pre-dorsal Length (PDL), Pre-pelvic Length (PPvL), Length before Anal fin (LBAF), Head depth (HD), Body Depth (BD), Depth of caudal peduncle (DCP), Upper jaw length (UPL), Lower jaw length (LJL), Eye diameter (ED), Length of dorsal fin base (LDFB), Pre-anal Length (PAL), Pre-pelvic Length (PPvL), Length of pectoral fins (LPF), and Length of tail fin (LTF), the number of circular scales on the caudal peduncle (CSCP), the number of branched dorsal fin rays (D), and the number of branched pectoral fin rays (P). Therefore, it was high variation in morphology among halfbeak population in West Sumatra waters. However, there was close morphology appearance between Batang Antokan and Batang Basampan, while Batang Batusan was discrete distantly among other populations. © 2015 BIOFLUX SRL.
