Popis: | To understand the differences in the stress sensitivities between domesticated Eurasian and Japanese indigenous strains of common carp (Cyprinus carpio Linnaeus 1758), we compared concentrations of cortisol released into the water in response to handling of the two types of strains. At 0.5 and 2 h after the handling treatment, the cortisol emission was greater from the Eurasian strain than from the Japanese strain. There were no differences between the strains in the cortisol levels after 4 to 24 h. We found that Eurasian strains exposed to the unnatural stressor (i.e., handling) exhibited a higher cortisol response than the Japanese strain. |
