Nitric oxide (NO), a simple diatomic molecule, has been shown to be a biological messenger of key importance, controlling an almost limitless range of functions in the body. In the present study NO gas was measured by chemiluminescence in the swim bladder of cod staying at surface level. All swim bladders contained NO, indicating that this compound might be involved in the regulation of the volume of the swim bladder.Key words: Cod, swim bladder, nitric oxide, nitric oxide synthase
