abstract
An attempt has been made to assess the hematological profile of snow trout Schizothorax richardsonii a cyprinid fish of different sex, male and female. For this purpose specimen from the wild as well as the farm-raised stock has been used. Hematological studies provide diagnostic keys of various diseases and are valuable indicators of the physiological state of the organism. The value of WBC was 20.4±5×103/µl, for males and 26.4±3.7×103/µl for females with highly significant difference (p<0.05). The value for hemoglobin (Hb) for males was 8.7±1. 7(g/dl) and for females 8.4±1. 5(g/dl), which was non-significant different, and a similar trend was observed for the hematocrit (Hct) values i.e. 25.4±5.4% for males and 24.8±4.8% for females with a non-significant difference. MCH value observed in this study for male and female is 130.63±13.94pg and 77.60±8.80pg. respectively in farmed condition and 37.3±14.4pg and 49.4±16.4pg in wild stock and this might be due to anemic condition in the farmed raised female. All the parameters in wild as well as the farmed condition were in the same trend of increasing hematological parameters in the present study, though the values differ in wild and farmed raised stock of snow trout Schizothorax richardsonii due to the different environmental conditions.
