Abstract
Present study was undertaken to analyze the ultrastructure and mineral content of the scale of fish species Barilius barna using SEM and EDX from the samples collected from the selected site of Kaushlya River adjoining Panchkula. The scales of Barilius barna were cycloid scales with an indistinct focus in the anterior region. The inter-circular space was maximum in the posterior region and minimum in the anterior part. Only two types of radii these were reported in the scale of species under report viz., primary radii and secondary radii with one distinct annulus, which indicated that this fish belonged to one year of age class. Six minerals were reported from the scale of the fish under report after the scale was subjected to energy-dispersive X-ray microanalysis (EDX) viz., calcium, carbon, oxygen, sodium, potassium and phosphate. It can be concluded that the circuli and the anterior part of the scale contains maximum percentage of minerals as compared to the other regions of the scales.
