“…The ODCs at 25 C were characterized by a low Hill coefficient (n Hill =1·1; r=0·99) and a Bohr factor of 0·81. The low Hill coefficient is consistent with the findings of Albers et al (1983).…”

“…The trout is an active species inhabiting well-oxygenated waters, and it has a high P a O 2 (c. 110 mmHg) combined with a low HbO 2 affinity, which favours effective oxygen delivery to tissues during activity (Nikinmaa, 1997). By contrast, carp tolerates hypoxic environments, has a low P a O 2 (15-40 mmHg) and a high HbO 2 affinity (Albers et al, 1983). Smith & Jones (1982) subjected trout to combinations of normoxia, hypoxia, hyperoxia and hypercapnia and found that ventilation increased with reductions of [O 2 ] a .…”

Gill ventilation in carp Cyprinus carpio increased 50% with a reduction of [O 2 ] a to 60% of the control value. Small decreases of inspired PO 2 also increased ventilation, which occurred without any significant changes of the blood gas picture. Ventilation increased with hypercapnia but only if [O 2 ] a became reduced by concomitant Bohr and Root shifts. Consistently, hypercapnia failed to increase ventilation when combined with hyperoxia. Therefore, it was not possible to ascribe any ventilatory response to specific CO 2 /pH receptors. 2000 The Fisheries Society of the British Isles

“…Greater oxygen uptake at a given P O 2 can be achieved by increasing haematocrit, haemoglobin concentration or erythrocyte number (Weber et al, 1976;Fernandes et al, 1999), blood oxygen affinity (i.e. decreased blood P 50 ) (Grigg, 1969;Weber et al, 1976;Albers et al, 1983;Andersen et al, 2009) or respiratory surface area (Sollid et al, 2005;Tzaneva et al, 2011;Nilsson et al, 2012). The Alaska blackfish does not appear to adopt any of these mechanisms.…”

The Alaska blackfish (Dallia pectoralis) is an air-breathing fish native to Alaska and the Bering Sea islands, where it inhabits lakes that are ice-covered in the winter, but enters warm and hypoxic waters in the summer to forage and reproduce. To understand the respiratory physiology of this species under these conditions and the selective pressures that maintain the ability to breathe air, we acclimated fish to 5°C and 15°C and used respirometry to measure: standard oxygen uptake (Ṁ O2 ) in normoxia (19.8 kPa P O2 ) and hypoxia (2.5 kPa), with and without access to air; partitioning of standard Ṁ O2 in normoxia and hypoxia; maximum Ṁ O2 and partitioning after exercise; and critical oxygen tension (P crit ). Additionally, the effects of temperature acclimation on haematocrit, haemoglobin oxygen affinity and gill morphology were assessed. Standard Ṁ O2 was higher, but air breathing was not increased, at 15°C or after exercise at both temperatures. Fish acclimated to 5°C or 15°C increased air breathing to compensate and fully maintain standard Ṁ O2 in hypoxia. Fish were able to maintain Ṁ O2 through aquatic respiration when air was denied in normoxia, but when air was denied in hypoxia, standard Ṁ O2 was reduced by ~30-50%. P crit was relatively high (5 kPa) and there were no differences in P crit , gill morphology, haematocrit or haemoglobin oxygen affinity at the two temperatures. Therefore, Alaska blackfish depends on air breathing in hypoxia and additional mechanisms must thus be utilised to survive hypoxic submergence during the winter, such as hypoxia-induced enhancement in the capacities for carrying and binding blood oxygen, behavioural avoidance of hypoxia and suppression of metabolic rate.

Oxygen consumption of carp acclimated at 10 and 20" C has been measured under routine conditions. Some compljcations and precautions necessary in continuous flow respirometry are discussed. Routine VO,, at different levels of hypoxia have been determined. Individual variation leads to scatter in the data and different methods of plotting the relationship between Vo2 and Po, .are proposed; attention is drawn to differences between inlet (or ambient) Po, and inspired Po . Using certain criteria a ' critical ' oxygen tension of about 95 mm Hg was found at 20"e; Qlo values are about 2 at normoxia and some suggestions of an increase near to the critical oxygen tension were found. Blood samples from the dorsal aorta showed rising Pa of 16 mm Hg which increased to 70-80 mm Hg when Pinsp was 90 and they then fall as*the inspired oxygen is lowered. During periods of deep hypoxia (25 mm Hg) blood lactate concentration increases steadily and indicates an increasing dependence on anaerobic mechanisms. I. INTRODUCHONCarp, Cyprinus carpio, are well known to be fish which can survive a wide range of environmental temperatures and levels of ambient oxygen concentration. These conditions range from almost complete anoxia in ponds covered with ice and at very low temperatures (Blazka, 1958), to conditions in summer when temperatures in excess of 25°C and supersaturation with oxygen are not uncommon (Jones, 1961;Garey & Rahn, 1970). Thus it is of interest to study the respiratory physiology of this fish to establish the mechanisms which enable such wideranging adaptation to occur. An interaction between temperature and respiratory processes is inevitable not only because of the direct effects of temperature on metabolic rate but also because of its marked influence on the oxygen content of water inspired by the fish. The main purpose of the present investigation was to obtain baseline information regarding the normal respiratory and blood characteristics of carp at two different temperatures, and to measure changes in routine metabolism of fish acclimated to these temperatures during exposure to lowered oxygen content of the water. Several previous investigations of this kind have been carried out but few have used a flow-through respirometer together with recent methods for cannulation of the dorsal aorta for blood sampling (Beamish, 1964;Garey, 1970).
