A total of 81 P. parva individuals were caught by using drift-nets with a mesh-size of 10 mm, and 24 P.parva individuals were caught by using seine nets with a mesh-size of 0.9 mm. The fork length of individuals which were caught (FL) were between 6.1 and 11.1 cm, and their weights (W) were ranged between 3.52 and 25.49 g. Dorsal fin-ray: III/8, anal fin-ray: III/ (6–7), pelvic fin-ray: I/7–8, pectoral fin-ray: I/12–15, Linea lateral: 35–37, Linea transversal: 4–6/4.
