Abstract :

The present study was conducted to evaluate the acute toxicity of catechol to Clarias batrachus along with its effects on haematological, biochemical and reproductive changes of fish. 96h median lethal concentration (LC₅₀) of catechol along with its 95% confidence limits was 30.74 (30.02-31.56) mg/l. Haemoglobin (Hb), Total Red Blood Corpuscle Count (TRBCC) and Total White Blood Corpuscle Count (TWBCC) increased significantly (p<0.05) compared to the control (0.00 mg/l) at various days of exposure. A significant decrease (p<0.05) in total serum protein along with maturity index (MI) and significant increase (p<0.05) in total serum glucose was observed in treated fish for both the sublethal doses compared to control in case of catechol. The findings of the study may help forecast safe levels of catechol and portray the health status of fish in natural water bodies.
