BIOCHEMICAL ALTERATIONS AS TOTAL PROTEINS (TP), ASPARTATE, AMINOTRANSFERASES (AAT) AND ALANINE AMINO TRANSFERASES (ALAT) INDUCED BY CHLORPYRIFOS (AN ORGANOPHOSPHATE) IN THE FISH CHANNA PUNCTATA (BLOCH)

Chlorpyrifos, an organophosphate, technical grade and 20% EC induced alterations in the biochemical parameters as total proteins (TP), Aspartate, Amino Transferase (AAT) and Alanine Amino Transferases (ALAT) in the fish Channa Punctata (Bloch), in the laboratory after exposing them in both lethal and sub-lethal concentrations for four days and 10 days respectively taking into consideration of 96 hour LC50 values of the respective toxicants.The fish vital organs, Gill, Liver, Kidney, Brain and Muscle are studied and found an appreciable quantity of percentage as decrement of TP and increment in AAT and ALAT enzymes in this present study. Proteolysis and an hormonal imbalance due to the toxic stress as an effect resulted in the protein breakdown and gluconeogenesis might be also be the reason of the decrement followed by increment of the activity of the two enzymes that are studied in the biochemical parameters of the fish, which ultimately resulted increase of free Amino acids.
