Maintaining high water quality is critical to the successful operation of a fish hatchery. To avoid pathogens, pollutants, and other contaminants, water is generally sourced from deep wells. Unfortunately, the high pressure in deep wells frequently leads to high levels or even super-saturation of undesirable dissolved gases. The presence of these gases can have detrimental effects on the delicate hatchlings.

Supersaturated nitrogen can lead to Gas Bubble Disease (causing lesions, convulsions, blindness and death). High levels of carbon dioxide lead to reduced growth and high mortality. The toxicity of high levels of hydrogen sulfide also leads to high mortality. Other dissolved gases, such as VOCs, have a detrimental effect on fish health. Conversely high levels of dissolved oxygen are required for proper growth and health. Poor dissolved gas management negatively impacts costs by increasing hatchling mortality and reducing quality.
