Three fish species with different strategies for anoxic survival (goldfish, tilapia, and common carp) were exposed to environmental anoxia (4, 3, and 1 h, respectively). The concentrations of high energy phosphate compounds and inorganic phosphate, besides the intracellular pH in the epaxial muscle were measured during anoxia and recovery by in vivo 31P NMR spectroscopy. The concentration of free ADP was calculated from the equilibrium constant of creatine kinase. During anoxia the patterns of… CONTINUE READING
