Abstract
The reference intervals for haematological and innate immune response variables of healthy adult yellow catfish Horabagrus brachysoma raised in captivity were determined. Reference ranges were established for all parameters and significant (P < 0.05) seasonal variations in most of the haematological and innate immune parameters were observed. Total erythrocyte count, packed cell volume, serum lysozyme and myeloperoxidase activities were found to be higher during winter season whereas most of the red blood cell indices, superoxide production by phagocytes, serum ceruloplasmin and anti-protease activities were marked to be significantly higher during rainy season of the year. Except high total leucocyte count and mean corpuscular haemoglobin, other parameters were found to be significantly lower during summer, possibly indicating a higher disease risk in summer months for this species. However, no significant variations in these variables were obtained between male and female catfish during breeding season. The information generated would be indirectly helpful for determining health status of this endangered species.
