Abstract: The aim of the current investigation was to obtain a basic knowledge of the hematology of the commercially important select fishes. Blood hematological parameters are often used to assess the health status and as stress indicators in fishes. The present study was undertaken to study and compare the hematological parameters of Indian major carps, exotic carps and select catfishes to establish the baseline values and normal rangesof blood parameters which would help toassess the health status of the fish as well asreference point for future comparative surveys. For all the fishes selected, five sexually immature and disease-free fish were examined and indices include RBC, WBC, PCV, Hb, MCV, MCH, MCHC and leucocyte counts were studied. The mean values were determined for each hematological parameter evaluated and the significance was set at 0.05. The study revealed a maximum number of erythrocytes, Hb and Ht for catfishes and minimum in common carp.However, significantly higher MCV, MCH, MCHC was in mrigal, common carp and catla respectively compared to other fishes. Further, highest platelet counts were observed in rohu and lowest in silver carp and maximum ESR in catla and minimum in rohu among the fish species. The results imply that the variation in hematological parameters depend on various intrinsic and extrinsic parameters and these could be used for biomarker and biomonitoring studies.
