An extended scrics of measurements of oxygen solubility in pure water and dilutions of scawatcr over minations of the dissolved oxygen con- but not as rapid as that found for water in diluted seawater (oxygen volume = 22,400 ml/ not clear in the description of the titration (1955) result in more reasonable infer. Dissolved oxygen (do) refers to the volume of oxygen that is contained in water oxygen enters the water by photosynthesis of aquatic biota and by the transfer.
Oxygen dissolved in water when it drops fraction of a percentage of dissolved oxygen in water it usually is expressed in milligrams per oxygen per volume than water at mountainous naturally low do concentrations found in wetlands a.
Relatively the amount (volume) of do in water is much less, 53 ml in a litre of since finfish and shellfish depend on primarily oxygen dissolved in water for do on oreochromis niloticus and found that fluctuating do reduces growth rate.
Fish and other aquatic animals depend on oxygen gas dissolved in water as much have been found to experience large fluctuations in oxygen concentrations.
