10.22376/ijpbs.2019.10.1.p1-12 Volume 3 Issue 4 2012(October - December) Blood pyruvate level in the fingerlings of lessThan i greaterThan Channa punctatus lessThan /i greaterThan when subjected upto 48 hours to 5.6 mg/l (a sublethal concentration) of hexavalent chromium exposure, revealed statistically no significant increase. However, a progressive significant increase in the blood pyruvate level was noticed upto 96 hours of exposure. The result may prove useful parameters to assess the hexavalent chromium toxicity in freshwater fish's in general and their juvenile stages in particular. J.P. SHUKLA, ANURADHA SHUKLA AND RAJESH.K.
