The effects of increased temperature on the physiological variable (heart rate, respiratory frequency, oxygen consumption, blood pressure, etc) of 2 Antarctic fish: Pagothenia borchgrevinki, Trematomus bernacchii
Listed in NASA Earthdata CMR
The effects of increased temperature on physiological variables in two Antarctic fish Pagothenia borchgrevinki (pelagic) and Trematomus bernacchii (sedentary) was investigated using a new technique to measure heart rate (ECG).
Description
Measurement of heart rate, respiratory frequency, and from these the respiratory/cardiac couplings in animals at rest and under stress were made. Animals were placed in a closed box respirometer and oxygen consumption was measured.
The data also allowed analysis of heart rate variability and determining control of the heart rate by sympathetic/parasymphathetic nervous input. Using cannulated fish, heart rate and blood pressure was recorded in fish acutely raised to 3, 5 and 10°C. Blood samples were analysed for haematocrit, haemoglobin and hormone (adrenaline, noradrenalin) concentrations.
