Haemoconcentration via diuresis in short-term hypoxia: A possible role for cardiac natriuretic peptide in rainbow trout

@article{citeulike:2703019, abstract = {Rainbow trout, exposed to acute hypoxia (decrease of oxygen level from full to 30\% air saturation for 1 h, stable 30\% air saturation for 2 h), showed more than twofold increase in urine flow rate.
