Cadmium is a well known heavy metal toxicant which can interfere with metabolism of carbohydrates, proteins and lipids by inhibiting the enzymes involved in the processes. In the present investigation, the effect of cadmium was evaluated on these biochemical constituents in two fresh water fish fry Labeo rohita and Cyprinus carpio. Fish fry of Labeo rohita and Cyprinus carpio were exposed to their respective sub-lethal concentrations (1/5th of LC50), 0.1998 ppm and 4.938 ppm of cadmium for a period of 20days. Total carbohydrates, proteins and lipids were estimated by standard biochemical procedures in control and exposed fish fry. Results showed significant fall in all the biochemical constituents and energy levels of exposed fish fry, indicating that the organism is under toxicant stress.

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 1.68 mg/kg for Chromium inCyprinus carpioandMasto symbollon, 0.20 to 7.52 mg/kg for Manganese inLabeo rohitaandMasto symbollon, 0.006 to 0.07 mg/kg for Cobalt inRastrelliger kanagurtaandPampus argenteus, 0.31 to 2.24 mg/kg for Copper inLabeo rohitaandPenaeus monodon, 3.25 to 14.56 mg/kg for Zinc inCyprinus carpioandMacrobrachium rosenbergii, and 0.01 to 2.05 mg/kg for Selenium inRastrelliger kanagurtaandPampus 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.
