Due to anthropogenic CO 2 emissions and the subsequent process of ocean acidification (OA), open ocean surface CO 2 levels are projected to more than double to ~1,000 μatm, and pH to decrease by ~0.3 units by the year 2100. When exposed to these CO 2 /pH values, several fish species display abnormal...

Due to anthropogenic CO 2 emissions and the subsequent process of ocean acidification (OA), open ocean surface CO 2 levels are projected to more than double to ~1,000 μatm, and pH to decrease by ~0.3 units by the year 2100. When exposed to these CO 2 /pH values, several fish species display abnormal behaviour in laboratory tests, an effect proposed to be linked to altered neuronal GABA A receptor function. This study examined the effects of constant and oscillating OA-like conditions on individual and group behaviour of juvenile blacksmith ( Chromis punctipinnis ), a social fish that regularly experiences CO 2 /pH fluctuations through kelp forest diurnal primary production and upwelling events. Blacksmiths were exposed to three treatments: control (pH ~7.92; pCO 2 ~540 μatm); constant acidification (pH ~7.72; pCO 2 ~920 μatm); and oscillating acidification (pH ~7.92, pCO 2 ~560 μatm (day), pH ~7.75, pCO 2 ~955 μatm (night)). After seven and eleven days, respectively, blacksmiths were administered individual light/dark preference and group shoaling tests, which are well-validated measures of anxiety-like behaviour and are modulated by GABA A receptors.
