Haematology and Erythropoietic Response in the Catfish, Clarias albopunctatus (Lamonte and Nichole 1927), Exposed to Sublethal Concentrations of Gammalin 20 (Lindane)
AbstractHaematological changes in the fish Clarias albopunctatus (Lamonte and Nichole, 1927) subjected to sublethal concentrations (0, 0.25, 0.5, 0.75, and 1.0 µg/L) of Gammalin 20 for 21 days were studied in a static bioassay renewal system. Compared with the control, the erythocytic count haematocrit values and haemoglobin concentrations were significantly reduced (P > 0.05) in the treatment groups. These parameters also differed in the treatment groups. There was significant leucocytosis (P > 0.05) in the fish exposed to sublethal concentrations of Gammalin 20. The Gammalin-20-exposed fish suffered macrocytic anaemia.
