ABSTRACT: The aim of the present work to study the comparative effects of a carbaryl (carbamate) and 2,4-D sodium salt (Herbicide) on haematological parameters of a freshwater catfish, H.fossilis, at different concentrations and time intervals. The catfish shows significance differences in their haematological parameters like RBC, WBC, Hb g%, haematocrit and clotting time at acute and subacute concentration for acute (96h) and short (10-20 days) time intervals but no remarkable changes were observed in sublethal concentration at long (30-60 days) term to both the toxicant. It is also observed that carbaryl is more toxic to fish then 2,4-D sodium salt.

KEYWORDS: Carbaryl, 2,4-D sodium salt; Haematological parameters; Heteropneustes fossilis
