Haematological changes in fish Heteropneustes fossilis under vanadium stress

ABSTRACT

Vanadium toxicity to fish Heteropneustes fossilis (Bloch) was studied for a period of two weeks. Haematological parameter like Total Erythrocyte Count (TEC), Haemoglobin (Hb) and Total Leucocyte Count (TLC)  altered  significantly  ( P < 0.001 ) in fish when  exposed  to 1,4, and 7 ppm of Vanadium (NaVO₃). Absolute value like MCH changed in accordance with the above parameter.

Key Words:  Seasonal changes, Chiloscyphus gollani, Solenostoma crenulata, Fossombroni  himalayensis, inverse relation.
