Impact of environmental changes on plasma biochemistry and hematological parameters of Himalayan snow trout, Schizothorax plagiostomus

AbstractThe hematological and plasma biochemical parameter study is recognized as a valuable tool for evaluating health status, physiological and pathological conditions of fish. In the present study, blood sampling was carried out with the aim to evaluate plasma biochemistry and hematological parameters of Himalayan snow trout,Schizothorax plagiostomus, that are altered due to variation in environmental conditions. The fluctuations in hematological parameters such as hemoglobin (Hb), red blood cell (RBC) count, packed cell volume (PCV), white blood cell (WBC) count, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV) and plasma biochemical parameters, such as total protein, glucose, total cholesterol and urea were compared with respect to gender and season. The hemoglobin and packed cell volume were obtained by cyanmethemoglobin and microhaematocrit method while total red blood cell count and total white blood cell count were obtained by Neubauer hemocytometer, respectively. Significant differences (P <  0.05) were observed in hematological parameters between sexes during summer season as compared to all the other seasons, except MCH and MCHC wherein no significant (P >  0.05) difference among the season has been noted. Between the sexes, the Hb concentration, total RBC count and PCV value were higher in males throughout the summer season, while the number of WBC count was recorded higher in female fi...
