The most important feature of this process is that no water is dumped as in existing fish raising facilities and the operator completely controls the water quality. All the water is continually recirculated and is continually sterilized by the use of OZONE gas in the O3 state. The OZONE gas in the water that is left over is then changed back to oxygen by the use of ultraviolet rays in the 254 nanometer range and is pumped into the water tank containing the aquatic life. By changing the OZONE back to oxygen the need for large air pumps is eliminated, thus stopping the harmful practice of pumping 78% nitrogen into the water. Twice as many fish, for example, can be raised one and one half times quicker with no dumping of fish wastes and with one half the utility bill. Fish health is controllable as well.
