The present study was conducted to determine and recover (with EDTA) the biochemical parameters (protein, amino acids and carbohydrates) level in liver, brain, kidney and muscles tissue of fingerlings of fish Labeo rohita (Ham.) in effect of mercury toxicity (0.13 ppm for 96 hrs). A significant reduction in protein and concomitant increase in amino acids and carbohydrates were recorded in all tissues when exposed to mercuric chloride. While compared, among the organs, liver was the major organ affecte by the effect of mercury chloride followed by brain, kidney and muscles tissues. During the recovery, all the parameters (measured) reached the near normal level, when the mercury toxicated fish was subjected to EDTA at required concentration (5 ppm) for another 4 days (96 hrs). The results suggested that the liver is a target organ for mercury toxicity and the exposure of EDTA competitively reduced the mercuric chloride toxicity in fish Labeo rohita (Ham.).
