In recent years, gas supersaturation has become a cause for concern at fish rearing facilities and fish research laboratories. Supersaturation characteristics and criteria necessary to design efficient degassing equipment for fishery units has been lacking. In spite of the lack of clear-cut criteria, ongoing rearing facilities and research laboratories have required degassed waters. In order to provide the necessary quality waters, degassing equipment has been designed, constructed, and installed at several facilities throughout the country. A review of the design process and operational results for various degassing systems at several research laboratories and hatcheries has been performed. The review indicates a need for the fish culturist and the designer to thoroughly understand both the culturist's requirements and the various degassing processes advantages and limitations.
