Toxicity Analysis of Coal Mine Effluent on Vital Organs of Heteropneustes fossilis (Bloch) Using Biometric and Biochemical Parameters

Alteration of certain energy reserves (total glycogen, lipid, and protein contents) and cell regulatory (total nucleic acids) molecules were periodically analyzed (5, 12, 19, and 26 days) in seven vital organs (muscles, kidney, liver, gills, air‐breathing organs, brain, and skin) of coal mine effluent exposed Heteropneustes fossilis (a species of Asian catfish). Changes in the biometric parameters of four organs (liver, kidneys, brain, and gills) were also simultaneously measured. The fish did not survive after 26 days because of significant (p
