    • Abstract


      The blood parameters like haemoglobin level, hematocrit value and erythrocyte count were estimated in the three air-breathing fishes,Anabas scandens (Cuvier),Ophiocephalus gachua (Hamilton-Buchanan) andMystus vittatus (Bloch).A. scandens possesses a higher haemoglobin level than the other two. Hematocrit values also follow the same trend. Maximum erythrocyte count is also obtained forA. scandens. The higher values of haemoglobin content, hematocrit and erythrocyte counts inA. scandens andO. gachua are suggested to serve as rich oxygen stores simulating diving syndromes among higher vertebrates, besides reflecting an adaptation to the mixed condition of systemic arterial blood.
