Evaluation of some serum parameters of Benni (Barbus sharpeyi)Brood stocks in spawning season

The current study carried out to determine some blood factor levels in Benni  (Barbus sharpeyi)brood stocks to achieve information about physiological changes due to reproduction and effect of reproduction on the serum parameters. Overall 42 randomly selected fishes including 24 females and 18 males ware studied. Blood samples were obtained from fishes in Dashte Azadegan Fish Culture Farm in a short time before spawning, serum was collected from blood and samples were analyzed in lab. The results show that mean values of Cholesterol, Glucose, Cortisol, Sodium, Potassium, BUN, Ig M were equaled to 247.07, 17.8, 40.9, 5.07, 139.09, 2.57, 1.46, and 62.8 respectively. The relation between serum parameters value with Sex and biometric factors of fishes were also studied. The results showed a statistical difference in Ig M mean value between male and female fishes (P<0.05) but there was no statistical difference in other factors between males and females. There was also a statistical difference in fishes with different weight and length for Potassium, Total Protein and Ig M (p<0.05).
