Poecilia latipinna was subjected to varying hydrostatic pressures in the laboratory which demonstrated the following points. The hyperbaric chamber is a suitable apparatus for testing gas gland secretion in this teleostean fish. Oxygen concentration within the swim bladder increased with increasing hydrostatic pressure. Pressures encountered by fishes at various levels of the water column and their effects on oxygen concentration in the swim bladder may be simulated in the laboratory.
