Abstract

Indian freshwater murrel Channa punctata were maintained in a floating cage in river Yamuna at Canal Colony, Kalindi Kunj, Delhi during the summer, monsoon and winter seasons in a year. Incidence of heavy metals (Pb, Hg, Fe, Cu, As) on fish scales were investigated by employing Scanning Electron Microscopy (SEM) and Energy Disruptive X-Ray (EDX) analyser. Fish scales revealed altered elemental composition and uprooted lepidonts. The present study indicated that structural integrity of the scale is compromised under stress of heavy metals and pollutants.
