Study of some haematological parameters in Barbus grypus, 1843 (Osteichthyes: Cyprinidae).

Values of some haematological indices were assessed in 30 Barbus grypus (mean length, 22.88 ± 4.16 cm; mean weight, 101.01 ± 58.50 g). The fishes were randomly selected from ponds of Dashte Azadegan Aquaculture Centre. The blood samples were collected from the caudal vein after adaptation to laboratory conditions. The values of the haematological parameter were measured using standardized and approved methods. The following values (mean±SD) were recorded. Packed cell volume (PCV), 46 ± 5.71%; haemoglobin (Hb), 9.5 ± 4.58 g/dL; white blood cell, 3,196.6 ± 716.54 in each mm; red blood cell, 1,378,667 ± 195,408.2 in mm, mean corpuscular haemoglobin concentration, 34.68 ± 20.23%; mean corpuscular haemoglobin 12.53 ± 70.02 (pg); mean corpuscular volume, 7.58 ± 34.1 (fl); neutrophils, 25.40 ± 6.04%; lymphocytes, 72.2 ± 4.58%; monocytes 1.13 ± 0.97% and eosinophil 0.6 ± 0.67%. A significant ( p < 0.05) interaction was found between total length, weight and PCV as PCV value increases with increasing weight and length. Data obtained from this study will serve as baseline haematological parameters for use in monitoring of health and productivity of B. grypus regarding the increasing interest in this fish for aquaculture purposes.
