We measured oxygen uptake rates to verify whether alterations in the partitioning between EWL Skin and EWL Resp were...

When the same species was exposed to more severe hypoxia (below a P O 2 of 6 kPa), gill ventilation ceased completely, such that air breathing may have provided a very large proportion of oxygen uptake at low swimming speeds (0.65 BL s –1 ) and also at high sustained speeds (2.4...
