abstract
Aim of this study was to investigate the haematological and serum biochemical parameters of two Catfishes Clarias batrachus (Linnaeus, 1758) and Heteropneustes fossilis (Bloch, 1794) of Odisha. In this study, the estimated values were fish as well as between the two species of catfishes as well as with respect to sex. Haematological parameters such as haemoglobin (Hb), total erythrocyte count(TEC), total leucocyte count(TLC), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin Concentration(MCHC) and the serum biochemical parameters like protein, albumin, globulin, glucose and cholesterol were measured and compared between and within the species as well as with respect to sex using One-Way Analysis of Variance (ANOVA) followed by Turkey’s pair wise comparison tests. All haematological parameters differ significantly (p<0.001) between C. batrachus and H. fossilis except PCV and MCV. Except albumin all biochemical parameters differ significantly between C. batrachus and H. fossilis.
