... that at least some teleosts have a third option: to reversibly remodel the gill morphology. Studies have shown that the lamellae of crucian carp Carassius carassius gills are embedded in a cell mass during normoxic conditions or at low temperature,while much of this cell mass dies off in hypoxia and at higher...

... acclimation as well as in hypoxia adaptation in poikilotherms, we studied HIF-1 DNA binding activity and HIF-1α expression in normoxia and during hypoxia (0.7 mg l –1 O 2 ) in crucian carp at temperatures of 26, 18 and 8°C. Temperature had a marked influence on HIF-1 in normoxia. Although HIF-1α mRNA levels...

...Jørund Sollid; Roy E. Weber; Göran E. Nilsson SUMMARY We have previously found that the gills of crucian carp Carassius carassius living in normoxic (aerated) water lack protruding lamellae,the primary site of O 2 uptake in fish, and that exposing them to hypoxia increases the respiratory surface...

...Jørund Sollid; Paula De Angelis; Kristian Gundersen; Göran E. Nilsson SUMMARY We show that crucian carp ( Carassius carassius ) living in normoxic(aerated) water have gills that lack protruding lamellae, the primary site of O 2 uptake in fish. Such an unusual trait leads to a very small...

...E. Nilsson Göran ABSTRACT In the brain, oxygen is required for both the synthesis and the degradation of monoamine transmitters, so monoaminergic systems can be expected to be strongly affected by anoxia. However, crucian carp ( Carassius carassius L.) may survive anoxia for many days or even weeks...

...Ian A. Johnston; Lynne M. Bernard ABSTRACT Crucian carp ( Carassius carassius L.) and Common carp ( Cyprinus carpió L.) were subjected to 2h progressive hypoxia followed by up to 6 h anoxia in closed respirometers at 15 °C. The concentrations of glycogen, glucose, phosphoryl creatine, alanine...
