- The tannery industries add chromium as one of the heavy metals to the aquatic environment and tannery waste waters continue to cause negative effects on the aquatic fauna. In the present study, the erythrocytic alterations produced on short-term exposure to sub-lethal concentration of chromium (20 mg/L) were investigated in fresh water air-breathing fish, Channa punctata (Bloch, 1793) for 24h, 48h and 72h respectively. The 96h LC50 of chromium salt, potassium dichromate was determined to be 33.125 mg/L. The results revealed statistically significant decrease in Total Erythrocytic Count (TEC), Haemoglobin (Hb) and Haematocrit (Hct %) in all experimental animals when compared to the control with an increase in exposure periods. The absolute corpuscular values like Mean Cell Haemoglobin (MCH) and Mean Cell Haemoglobin Concentration (MCHC) also exhibited significant increase in fishes of experimental groups. However, the Mean Cell Volume (MCV) contrarily exhibited a fluctuating pattern. The depression of erythrocytic parameters clearly indicates that the fishes have become anaemic due to sublethal exposure of chromium.
