Evaluation of Haematological Parameters and Endosulfan Accumulation in Blood of Channa punctatus Followed by Subsequent Recovery

Abstract

Present study has been undertaken to investigate alterations in some haematological parameters along with endosulfan accumulation in blood of Channa punctatus after sub-chronic exposure to endosulfan. A statistically significant decline is observed in RBC, Hct, Hb and MCHC content in all the treated groups, reflecting an anaemic condition of the fish. Results indicate significant elevation in WBC, MCV, MCH, blood glucose and endosulfan content in blood, indicating a stress condition. Post exposure recovery was noted on depuration for another fortnight. Mild recovery was noted in haematological parameters and blood glucose along with slow elimination of endosulfan.
