    • PURPOSE:To breed fish and small animal with little effort by connecting a water-suction pipe of a pump to a water-hole opened at a side part, etc., of a water tank, introducing air, etc., into a discharge pipe of the pump, connecting a closed air-water mixing chamber and opening an ejection port in the water tank. CONSTITUTION:Water is poured into a water tank 2 to an extent to almost submerge a water-hole in water. Water in the tank is sucked from the bottom by driving a pump 3, transferred to ejection pipes divided into two with a branch and ejected into the water tank through each ejection port to form a circulation path. The water passing through the 1st ejection pipe 5 is ejected to the upper part of a filter material through an ejection port placed in a filter 7 above the water tank, filtered and dropped from the discharging port on the water surface of the tank. When water is passed through the 2nd ejection pipe 8, air, etc., are sucked into the channel through an air hole 10 by the action of injector, joined with water and stirred. Air bubbles are discharged through an exhaust valve and water is exclusively discharged into the tank.
