Inadequate concentration of dissolved oxygen has long been recognized as a limiting factor in intensive fish production; thus the physical, chemical and biological regulating of dissolved oxygen in a pond is of paramount importance to the fish culturist. The solubility of oxygen, or the water's carry capacity of oxygen, decreases as the temperature increases.
Dissolved oxygen is removed from the water by respiration of fish, by benthic (aquatic) organisms and by respiration of plankton (phytoplankton included). The plankton are microscopic plants that live in the water. They go through the process of photosynthesis, thus taking energy from the sun and nutrients from the water; they absorb carbon dioxide from the water and give off oxygen during daylight hours.
When these plants (plankton) become so thick the sun's rays cannot penetrate deeply enough into the water, the lower layers of plankton begin to die from lack of sunlight. At this point the water usually changes from a greenish to a brownish or grayish color; and the decaying process begins to use up oxygen and give off carbon dioxide. Sometimes a scum will form on the water's surface.
Fish are more susceptible to disease and parasites when they have been subjected to an oxygen stress period. They do not feed or grow as well when oxygen stays at a low level of three or four ppm for a prolonged length of time.
Five to eight lbs. per acre foot of Potassium Permanganate can be added to oxidize the dead and decaying organic matter. This can be repeated whenever necessary.
