[Control of the respiration in teleostean fish: respiratory reactions to abrupt changes in the oxygenation of the medium].
In the trench, carp and trout, an abrupt change in the partial pressure of ambient oxygen leads to a change in arterial oxygen tension which, within 1.5-2.6 seconds, elicits cardiac and ventilatory reactions. By their short latency, these responses may be explained as a modification of chemoreceptor activity, and resemble respiratory chremoreflexes of higher vertebrates.
