ResumoThe thermodynamic variable pressure has been studied for a long time by a broad spectrum of disciplines but the effects of pressure per se on living organisms have proven to be much more difficult to study.The main difficulty is to dissociate the effects of pressure from those of the partial pressure of the gases in air-breathing animals.However, in fish and other aquatic organisms that difficulty does not exist (Fenn, 1967).The main problem with long-term exposure to high hydrostatic pressures is the maintenance of aquatic organisms both under pressure and in an environment with stable water conditions.For more than a hundred years a number of different techniques and systems have been used to achieve this (
