Swimming performance and respiration data of Polar cod (Boreogadus saida) under future ocean conditions
Polar cod (Boreogadus saida) were acclimated for four months to different temperatures (0, 3, 6, 8°C) and PCO2 (390 and 1170 µatm) conditions. Subsequently, B. saida were exercised in a Brett-type swimming tunnel at their respective acclimation conditions the fourth day after feeding. The swimming p...
