Seasonal changes in hematological parameters of snow trout Schizothorax plagiostomus (Heckel 1838)

Abstract

Hematological parameters are repeatedly used as diagnostic and effective tools to assess the health status of fish and these parameters are not only varied with season but also varied between the sexes with in the species. Therefore, the purpose of the present study was to investigate the variation in hematological parameters of Schizothorax plagiostomus with respect to season and sex. This study was carried out in a stretch of time from 2014 to 2015 and the fish were collected from river Jhelum of Kashmir Himalayas. Blood was analyzed using different techniques and difference in hematological parameters including hemoglobin (Hb), total erythrocyte count (RBC), total leucocyte count (TLC), hematocrit (Hct), mean corpuscular hemoglobin (MCH), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC) from 30 males (Weight, 311.62±25.76gm; length 33.5±3.26cm) and 31 females (Weight 335±32.55gm length 32.99±3.76cm) were reported during the present study. The results indicated that the highest hemoglobin concentration red blood cell count, hematocrit, mean corpuscular hemoglobin, mean corpuscular volume were found in males which were significant (p
