Changes in levels of cortisol, glucose and sex hormones during transportation of southern Caspian Kutum (Rutilus frisii kutum) spawners
Physiological changes in cortisol, glucose, testosterone and 17b-estradiol levels were studied in Rutilus frisii kutum spawners during transportation in April, 2006. The fish were held in plastic tanks in two treatments 1fish/2L and 1fish/1L sea water in several replications. Their blood was collected at 0, 10, 20, 30 and 60 min after capture. A significant increase in concentration of cortisol and glucose was found with the transport time. Initial levels of cortisol were similar in the two treatments ranging between 480.7c22.34 and 476.6c18.61 ng/ml respectively.
