Fig. 5. The effects of injecting bovine carbonic anhydrase (CA; N=9) on
(A) O2 uptake
(
O2) and (B)
CO2 excretion
(
CO2) in P.
dolloi. Aerial gas transfer is depicted by the filled portions of each
bar and aquatic gas transfer by the unfilled portions. (C) Representative
recordings of aerial CO2 transfer (grey line) and aquatic
CO2 transfer (black line) from a single fish. Note that in this
particular experiment, only the air chamber was flushed after the control
period of respirometry. A statistical difference from the control group is
denoted by an asterisk (P<0.05).
