Respiratory and swimming performance data of Polar cod (Boreogadus saida) under progressive hypoxia and warming ...

The present study investigated the response of an Arctic keystone species, Polar cod, Boreogadus saida, to hypoxia and warming. We measured the respiratory capacity (standard, routine and maximum metabolic rates, SMR, RMR, MMR, aerobic scope, critical oxygen saturation (Pcrit)) and swimming performa...

Description
Summary:The present study investigated the response of an Arctic keystone species, Polar cod, Boreogadus saida, to hypoxia and warming. We measured the respiratory capacity (standard, routine and maximum metabolic rates, SMR, RMR, MMR, aerobic scope, critical oxygen saturation (Pcrit)) and swimming performance of Polar cod under progressive hypoxia at 2.4 °C and after warm acclimation to close to the species' thermal limit (10.0 °C) via intermittent-flow and swim tunnel respirometry. Polar cod for the experiments in this study were caught in October 2018 during RV HEINCKE expedition HE519 in Billefjorden (78°34'59.99 N 16°27'59.99 E). In total 46 fish were selected for this experiment and divided into two groups. The first group (n = 30, group C) measured 19.7 ± 1.3 cm and 39.6 ± 9.5 g and was kept at habitat temperatures. The second group (n=16, group WA) with an average size of 19.8 ±1.9 cm and weight of 41.3 ± 10.1 g, was progressively acclimated to 10.0 °C (warming rate: 1.5 °C month-1) and then kept at this ...
