effect of sex on the haematological parameters of reared shirboat fish (barbus grypus)

for intensive rearing of fish with minimal losses, it is necessary to be aware of health status of fish. blood variables are useful criteria for showing physiological disturbances in intensively farmed fishes and can provide important information for diagnosis and prognosis of diseases. the aim of the present study was to show hematological parameters in haematological evaluation is gradually becoming a routine practice for shirbout fish when intensively bred. in this study, 60 clinically healthy barbus grypus, were caught from culturing pools in khuzestan province. blood samples were taken from caudal vein and the levels of hematological parameters were determined. comparison between sexes were done using student t-test and pearson correlation coefficient with fisher's test. in this study the overall mean of total red blood cells, total leukocyte count, hemoglobin, mean cell volume (mcv), mean cell hemoglobin (mch), mean cell hemoglobin concentration (mchc), hematocrit, lymphocyte, neutrophil, eosinophil, and monocyte were (1.41 ±0.035)|*|106 , (12.5 ±0.57)|*|103 cell/ l, 6.5 ±0.1 g/dl , 261±4.87 fl, 45.7±0.88 pg, 17.6 ±0.27, 36.9±0.7, 56.2 ±0.59, 40±0.52, 1.1±0.15 and 2.8 ±0.22 %, respectively. in terms of these parameters, there was not significant difference between sexes (p
