ABSTRACT:
A fish rearing system. Water is recycled from a fish rearing tank to a primary filter. Ammoniacal nitrogen load is reduced by rapid removal of nitrogenous solids. The water is formed through a biological filter containing a particulate medium of small particle size. Prior removal of solids prevents filter blockage. The filter is provided with backwash means that include an air scour. The water is reaerated after the filter and returned to the fish rearing tank.
