Ocean acidificationmay alter olfactory-driven behaviour in fish by direct effects on the peripheral olfactory system; olfactory sensitivity is reduced in CO2-acidified seawater. The current study tested whether this is due to elevated P-CO2 or the consequent reduction in seawater pH and, if the form...
