Willmer (1934) suggested that the acidity of the water and
the presence of carbonic anhydrase in the blood may assist the passage of carbon
dioxide across the gill membranes.It seems safe to conclude that acidity of the water
aids the transfer of carbon dioxide into the blood and therefore low pH at least assists
in the control of breathing by acting together with carbon dioxide.
It is of interest that an increase in CO2 content of the water always results in an
increased frequency of air breathing in Anabas.A similar effect was found in lung-
fishes by Johansen et al.(1967) and by Johansen & Lenfant (1968).The mean,maximum
and minimum intervals between air breaths diminish slowly with increasing CO2
content.
When climbing perch are in saturated tap water the mean time interval between
air breaths is about 10 min.It was found that when gas mixtures of oxygen and
nitrogen were bubbled into the water,air-breathing increased to higher levels (Tables
1-3).This increase in air-breathing occurred even though the fish had a raised
branchial ventilatory frequency.It can be seen from Tables 2 and 3 that though the
total CO2 content of the water was about 9-10 vols.% there was an absence of
free carbon dioxide in such water brought about by bubbling of the nitrogen gas
mixture.
