Abstract:

To date, numerous studies have shown negative impacts of CO2-acidified seawater (i.e. ocean acidification, OA) on marine organisms including calcifying invertebrates and fishes; however, limited research has been conducted on the physiological effects of OA on polar fishes and even less on the impacts of OA on early developmental stages of polar fishes. We evaluated aspects of aerobic metabolism and cardiorespiratory physiology of juvenile emerald rockcod Trematomus bernacchii, an abundant fish in the Ross Sea, Antarctica, to elevated partial pressure of carbon dioxide (pCO2) (420 [Ambient], 650 [Moderate] and 1050 [High] μtam pCO2) over a one-month period. We examined cardiorespiratory physiology including heart rate, stroke volume, cardiac output and ventilation, whole organism metabolism via oxygen consumption rate, and sub-organismal aerobic capacity by citrate synthase enzyme activity. Juvenile fish showed an increase in ventilation rate under High pCO2 compared to Ambient pCO2, while cardiac performance, oxygen consumption, and citrate synthase activity were not significantly affected by elevated pCO2. Acclimation time did have a significant effect on ventilation rate, stroke volume, cardiac output and citrate synthase activity, such that all metrics increased over the 4-week exposure period. These results suggest that juvenile emerald rockcod are robust to near-future increases in OA and may have the capacity to adjust for future increases in pCO2 by increasing acid-base compensation through increased ventilation.

Comment:

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2021) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2021-12-20.
