چکیده | ||
Kutum, Rutilus frisii kutum wild broodstocks (970 ± 90 g) were subjected to captivity during their upstream migration and their physiological responses to the stressful condition was assessed. No changes in cortisol levels by was observed after captivity (p < /em> > 0.05). An increase in glucose levels (1.8 fold) was observed after captivity (p < /em> < 0.05), but plasma lactate concentration was not changed (p < /em> > 0.05). Chloride and sodium levels decreased following captivity (p < /em> < 0.05), while no change in calcium levels was obtained in response to stress. Hematological parameters including red blood cells (RBC), hematocrit (Hct), mean corpuscular volume (MCV), and white blood cells (WBC) were not significantly affected by captivity (p < /em> > 0.05), whereas hemoglobin (Hb), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) decreased (P < 0.05). In addition, the decrease in the number of circulating total lymphocytes and the increase in circulating neutrophiles were observed after captivity (p < /em> < 0.05). | ||
