Gas exchange in the gourami, Trichogaster trichopterus, an obligate air breather, is achieved both by branchial exchange with water and aerial ex-change via labyrinth organs lying within the suprabranchial chamber. Ventilation of the suprabranchial chamber, MOt, MCOl, gas exchange ratios of both gills and labyrinth organs, and air convection requirements have been measured under conditions of hypoxia, hyperoxia or hypercapnia in either water or air. In undisturbed fish in control conditions (27 °C), air breathing frequency was 12 breaths/h, gas tidal volume 30 fi\/g, total oxygen uptake 5-2 //.M/g/h and total carbon dioxide excretion 4-1 /AM/g/h, indicating a total gas exchange ratio of approximately o-8. The aerial labyrinth organs account...
