Iron Induced Changes in Biochemical Composition of Freshwater Fish Gonoproktopterus Kolus (SYKES)

Abstract

Fingerlings of freshwater fish Gonoproktopterus kolus (Sykes) were exposed to Ferric Chloride (FeCl 3) in acute toxicity (96 hr.) experiment. The LC 0 and LC 50 concentrations were 1.370 ppm and 1.928 ppm respectively. After acute exposure, various tissues viz. gill, liver, muscle, kidney and intestine were obtained separately from control, LC 0 and LC 50 groups. These tissues were subjected for  estimations of glycogen, protein and lipid using standard methods. As compared to control group, the glycogen content in all the tissues decreased considerably. The total protein content decreased in all tissues except, kidney in LC 0 group. Total lipid content decreased in all tissues after acute exposure, as compared to control group.  It was observed  that, the fish Gonoproktopterus kolus exposed to Ferric Chloride in acute toxicity experiment caused depletion in biochemical composition in various tissues.
