All 20.000 different fish species vary greatly in their ability to tolerate and survive fluctuating oxygen concentrations in the water. Especially fish of the genus Carassius, e.g. the crucian carp and the goldfish, exhibit a remarkable tolerance to limited/absent oxygen concentrations. The metabolic changes of anoxia-tolerant crucian carp were recently(More)
The crucian carp (Carassius carassius) can tolerate anoxia for days to months, depending on the temperature. In this study, we applied 1H-NMR-based metabolomics to polar extracts of crucian carp brain, heart, muscle and liver samples obtained from fish exposed to either control normoxic conditions, acute anoxia (24 h), chronic anoxia (1 week) or(More)
The zebrafish has become a valuable vertebrate model organism in a wide range of scientific disciplines, but current information concerning the physiological temperature response of adult zebrafish is rather scarce. In this study, zebrafish were experimentally acclimated for 28 days to 18, 26 or 34 °C and a suite of non-invasive and invasive methods was(More)
Mitigation and adaptation to environmental changes, including global warming, are currently on the agenda in all countries. Our everyday life requires now, more than ever before, a direct action to reduce environmental degradation. It affects both the economy, particularly in developed countries, and the dependence on natural resources, particularly in(More)
