Dissolved oxygen is necessary for aquatic species, such as fish and insects, that rely on water for their oxygen intake, absorbing it through their gills or bodies.Dissolved oxygen is an important parameter used in water quality monitoring. The concentration of DO in water is dependent on the temperature of the water. Warm water hol...
