Fig. 6. Gill Rh mRNA expression in rainbow trout after 12 h of exposure to 1%
CO2 in air (CO2), 1% CO2 in air with 10 mmol
l–1 Hepes-buffered water (CO2+Hepes), 100% air
with 10 mmol l–1 Hepes-buffered water (Air+Hepes) and high
environmental ammonia (HEA; 1.5 mmol NH4HCO3). Control
fish were exposed to 100% air for 12 h in unbuffered water. Expression data
were normalized to ng total RNA concentration with the control value set to
one. Asterisks indicate significant difference from the control
(P<0.05). Data are means ± s.e.m. (N=6).
