Haematological parameters are often used to assess the health status and as stress indicators in fishes. In this present study, the haematological parameters such as red blood cell count (RBC), white blood cell count (WBC), haematocrit (HCT), haemoglobin (HB), mean cell volume, mean cell haemoglobin and mean cell haemoglobin concentration, RBC/WBC ratio, erythrocyte sedimentation rate (ESR) and biochemical such as serum glucose (GLU), protein (PRO), cholesterol and urea (UR) of seven teleost fish species were determined. Statistical analysis confirmed that differences in haematological parameters between all the species were ( P  < 0.01) significant. The result revealed that RBC, RBC/WBC ratio, HCT, HB, ESR, PRO, GLU and UR was significantly correlated at P  < 0.05 level. RBC/WBC level was more due to the decrease in WBC during the study. These differences can be attributed to the physiological acclimatisation of the fish to their living conditions and feeding regime, which influences the energy metabolism and consequently, the health of the fish.
