Zusammenfassung

The Antarctic fish Notothenia coriiceps undergoes winter metabolic suppression irrespective of water temperature.
This endogenous suppression and activation of metabolic processes, independent of body temperature demonstrates that Notothenia coriiceps were effectively putting themselfs on ice during winter months until food resources improved.
This study demonstrates that some fish species can enter a dormant state similar to hibernation that is not temperature driven and presumably provides seasonal energetic benefits.
