The present research was carried out to study the basic structure, morphometric measurements and meristic counts of the scales of a Freshwater fish, Channa striata (Bloch, 1973). For this purpose, scales of the head region, lateral line, and caudal region were studied under microscope. Results show that C. striata has cycloid scales. The head scales lacking the radii (RDS) while lateral line scales and caudal scales have 7-20 and 9-18 radii, respectively. The total length of scale (TLS) was observed as 4.0-8.3mm for head scales, 4.3-6.1mm for lateral line scales and 3.0-5.9mm for caudal scales. The width of scales (WDS) of head, lateral line, and caudal region was examined as 5.0-9.9mm, 3.0- 6.1mm and 1.7-4.0mm, respectively. The oval or pear-shaped focus was present at the center of the scale. The distance of the focus from the posterior margin of the scale (Rs) was noted ranging 2.9-6.0mm in head scales, 2.0-4.0mm in lateral line scales and 1.1-3.1mm in caudal scales.
