ABSTRACT:
A fish rearing system. The fish rearing system includes a rearing tank, filtration means and means to recycle water in the system. The system includes an ozone contact unit in which, when the system is in use, a predetermined amount of recycling water can be contacted with ozone in an amount sufficient to lower the total nitrite content of the water to a level acceptable to fish life but not leave free ozone in the water re-entering the rearing tank.
