1. Investigation of the cardiovascular control of notothenioid fish (Pagothenia borchgrevinki and Trematomus bernacchii) [K057_1992_1993_NZ_1]
It has been shown that under stress, red blooded notothenioids increase their haematocrit by contracting the spleen thus releasing red blood cells and increasing the heart rate. The increase in heart ...


2. Measurements of blood pressure, heart rate, blood flow, PO2 and oxygen content of blood and examination of the heart of Antarctic fish Pagothenia borchgrevinki with x-cell disease and healthy fish [K057_2000_2002_NZ_1]
The presence of x-cell disease in Antarctic fish, a disease that affects the gills by producing lesions on the gill tissue, has been shown to affect the ability of the fish to take up oxygen and can ...


3. Respiration rates and physiological changes of Antarctic fish Pagothenia borchgrevinki exposed to fuel oil, acute vs chronic exposure [K057_1989_1991_NZ_1]
The potential for oil pollution in the Ross Sea is increasing as shipping activities increase due to base operations and tourism. The effects of diesel fuel oil on Antarctic fish survival and physiology ...


4. The characteristics of an isolated in situ Pagothenia borchgrevinki heart: heart rate and pressure, the effects of drugs, innervation of the heart and biochemical work of the blood and muscle tissue [K057_1996_1997_NZ_3]
The characteristics of an isolated in situ fish heart was investigated. A Pagothenia borchgrevinki fish was killed and its heart was exposed and isolated from its blood supply, but left in place ...


5. The dynamics of red blood cell release and uptake by the spleen and the control of red blood cell swelling from the effects of stress in two species of Antarctic fish, Pagothenia borchgrevinki and Trematomus bernacchii [K057_1996_1997_NZ_2]
In vitro experimentation determined that red cell swelling is a consequence of activation of a Na+/H+ antiporter located on the red cell membrane. The antiporter is controlled by a ?-adrenoceptor ...


6. The role of the spleen in producing red blood cells during stress (measurements of haematocrit, haemoglobin, chloride, adrenaline conc., spleen mass) in Antarctic fish (Pagothenia borchgrevinki, Trematomus bernacchii) [K057_1991_1992_NZ_1]
The effects of stress (both hypoxia and exercise) on haematocrit in Antarctic fish was investigated with the aim to examine red cell release from the spleen under conditions of stress. The spleen ...
