N2 - When the Adriatic sturgeon Acipenser naccarii was exposed to progressive hypoxia under static conditions, it exhibited a linear decline in O-2 uptake, behaving as an 'oxyconformer'. When, however, it was allowed to swim at a low sustained speed, it could regulate O-2 uptake down to a mean +/- S. E. critical PO2 (P-crit) of 4.9 +/- 0.5 kPa (n = 6). At moderate levels of hypoxia, static fish exhibited significant reductions in arterial blood O-2 content, and increases in plasma lactate, which were not observed in swimming animals.
