Metabolic prioritizations of Polar cod (Boreogadus saida) at ambient and elevated water temperatures@en

Two groups (n = 8, n = 5) of Polar cod (Boreogadus saida) were acclimated to both 0 and 6°C. The smaller groups were used to investigate specific dynamic action (SDA) (treatment \"digestion\"). Each fish of the larger groups was used for exercise tests in an unfed and fed state (treatment \"exercise\" and \"exercise & digestion\", respectively) at their respective acclimation temperatures as well as in a fed state acutely exposed to an intermediate temperature (3°C). SDA measurements lasted for 18 and 9 days at 0 and 6°C, identical to the food-deprivation period of B. saida in the exercise approach. Feeding was conducted in the common tank. Accordingly, daily rations reflect the mean food consumption per treatment. Each fish was allowed to feed for at least 2h before the start of the experiments. […]
