An attempt has been made to evaluate the effect of inorganic pollutant (nitrate) on biochemical parameters of the fish A. morar. The studied parameters were Glucose, cholesterol, protein, triglycerides, phosphatases and transaminases. LC50 value of fish, A. morar for nitrate was found to be 2mg/l. Three sublethal concentrations viz., 25% (0.5mg/l), 50% (1mg/l) and 75% (1.5mg/l) of LC50 value of nitrate were employed for the experiment. The experiment was set up for 9 weeks and effect was observed at weekly intervals. The studies revealed when fish exposed to sublethal concentrations at weekly intervals, exhibited hyperglycemia, hypercholesterolemia, hyperproteinaemia with significant increase in concentrations of triglycerides and phosphatases. The observed alterations were ultimately become the causative for hampering the entire metabolic machinery. The anomalies observed in the above mentioned parameters were found to exhibit more effect as the concentration as well as chronicity of the experiment progresses.
