Abstract
The partitioning of O2 uptake between aquatic and aerial gas exchange and its dependence on ambient water PO2 was studied in the facultative air breathing teleost Synbranchus marmoratus, after acclimation to well aerated water and after acute and chronic exposure to hypoxic water. O2 uptake was also studied following acute air exposure and after prolonged entrapment in soil. Breathing rates during water and air breathing in response to reduced water PO2 and tidal volume during air breathing were also studied.
