The effect of hyperoxia on the breathing of marine fishes

Effects of O2 supersaturation on metabolism and growth in juvenile turbot (Scophthalmus maximus L.)

“…There were no influences on nitrogenous excretion, no signs of stress and no disturbances to thyroid hormone regulation. The MO 2 of resting turbot was not influenced by exposure to O 2 -supersaturated water, which is in agreement with observations made on other fish species (Dejours et al, 1977;Wilkes et al, 1981;Barrett and Taylor, 1984;Berschick et al, 1987). Exposure to hyperoxic conditions did not elicit moderate anaemia in turbot, although this has been observed in rainbow trout (Jewett et al, 1991;Caldwell and Hishaw, 1994).…”

Oxygen Acquisition of the Reedfish, Erpetoichthys Calabaricus

“…In some air-breathing fishes, aquatic hypercapnia inhibits branchial respiration while simultaneously stimulating aerial respiration, a combination of responses which would avoid respiratory acidosis (Johansen, 1971;Singh, 1976). However, other studies have indicated that some species of fish may regulate their blood pH with other mechanisms (Smatresk & Cameron, \9%2a,b,c;Graham & Baird, 1982;Dejours, Toulmond & Truchot, 1977). The rates of gill ventilation for the 3 % O 2 and the 3 % O 2 , 5% CO 2 exposures were not significantly different; however, the gill ventilation frequencies were significantly elevated in fish exposed to the 8% O2, 5% CO 2 gas mixture.…”

Spatial distribution and activity patterns as welfare indicators in response to water quality changes in European sea bass, Dicentrarchus labrax

“…For instance, in hypoxic conditions, the oxygen quantity is limited, therefore fish have to adapt their physiology and behaviour to maximize oxygen uptake and avoid death by asphyxia (Chapman & Mckenzie, 2009). Then, Hyperoxia may alter the equilibrium of ions in the gill, causes a decrease in the ventilatory frequency inducing oxidative damages or triggers diseases and thus can cause fish death (Dejours et al 1977;Liepelt et al1995;Brauner et al 2000).…”
