  • Description: Petroleum-related activities in Arctic waters are rapidly increasing parallel to the ongoing thinning of the Arctic sea ice. As part of a series of studies on petroleum-induced stress in polar cod Boreogadus saida, we tested the effects of acute (~60 min) and chronic (4 weeks) exposure to the water soluble fraction (WSF) of petroleum on whole body metabolism inferred from measurements of oxygen consumption rates. The exposure of polar cod to WSF leads to a statistically significant depression in routine metabolism in the order Control (0.260 mg O₂ g fish⁻¹ h⁻¹; N = 6) > Chronic (0.191 mg O₂ g fish⁻¹ h⁻¹; N = 6) > Acute (0.110 mg O₂ g fish⁻¹ h⁻¹; N = 2), decoupling of routine metabolism and body mass but possibly also to a partial metabolic compensation after 4 weeks of exposure. The results are reviewed in context with similar studies on Antarctic and non-polar fishes.
