Exogenous thyroid hormones regulate the activity of citrate synthase and cytochrome c oxidase in warm- but not cold-acclimated lake whitefish ( Coregonus clupeaformis )

Highlights • The activity of oxidative enzymes in lake whitefish varies with acclimation temperature. • Metabolic responses to hyperthyroidism are temperature- and tissue-specific. • Thyroid hormones may mediate metabolic adjustments induced by thermal acclimation.
