Abstract [en]

Cannulated specimens of the benthic Antarctic teleost Trematomus bernacchii were subjected to a five min period of handling stress, following which blood pressures were measured and then blood samples taken for measurement of plasma catecholamine concentrations. There were two control groups of fish, one group of undisturbed fish at Scott Base, Antarctica and the other group of undisturbed fish measured in Christchurch. Plasma catecholamine concentrations were not changed following 5 min of acute handling stress. However, heart rate, ventral aortic blood pressure and haematocrit were elevated following handling, suggesting increased sympathetic nerve activity. The low plasma catecholamine concentrations measured in all three groups of fish are similar to those found in other species of teleost at rest. The resting heart rates found in this series of experiments were approximately double those recorded in previous work on this species and this difference may be correlated with the length of time that the fish are held in captivity. The fish transported to Christchurch also had higher mean cell haemoglobin concentrations (MCHC) and lower plasma chloride concentrations.
