The objective of the present study was to investigate trace metal levels of different varieties of fresh water fish using Inductively Coupled Plasma Mass Spectrophotometer after microwave digestion (MD-ICPMS). Fish samples were collected from the outlets of twin cities of Hyderabad and Secunderabad.The trace metal content in different varieties of analyzed fish were ranged from 0.24 to 1.68mg/kg for Chromium in Cyprinus carpio andMasto symbollon, 0.20 to 7.52mg/kg for Manganese in Labeo rohita andMasto symbollon, 0.006 to 0.07mg/kg for Cobalt in Rastrelliger kanagurta and Pampus argenteus, 0.31 to 2.24mg/kg for Copper in Labeo rohita and Penaeusmonodon, 3.25 to 14.56mg/kg for Zinc inCyprinus carpio andMacrobrachium rosenbergii, and 0.01 to 2.05mg/kg for Selenium in Rastrelliger kanagurta and Pampus argenteus, respectively. Proximate composition data for the different fishes were also tabulated. Since the available data for different trace elements for fish is scanty, here an effort is made to present a precise data for the same as estimated on ICP-MS. Results were in accordance with recommended daily intake allowance by WHO/FAO. 1
