- GAS BUBBLE DISEASE
- Armed Forces Institute of Pathology
- Gas bubble disease occurs in aquarium fish when the pressure of oxygen or nitrogens in the water exceeds the ambient atmospheric pressure. Nitrogen is a more common cause as oxygen may be metabolized. Supersaturation of water with oxygen or nitrogen may result from leaky pumps in aquaria which take in excessive air, rapid heating of cold water (it may release trapped gas) or may be seen in animals transported by air. Acute gas bubble disease may result in mortality due to systemic emboli; more chronic bubble disease may result in emboli within in the gills, eye, or fins, resulting in tissue damage to these organs.
