PURPOSE: To provide the subject device which distributes food on the water surface of a water tank for automatically feeding the group of aquatic animals, reduces the exposure of the food to wet environment on the water surface and is provided with the low possibility of blocking by specifically constituting the device. CONSTITUTION: First an endless screw arranged in the channel 3 of a housing 2 rotation-driven by an assembly 34 fixed to a back gear to move the food 15 to an outlet zone 17 through an intermediate zone 20 from the starting zone of the channel 3 of the housing. Next, the food is dropped onto the water surface of the water tank through the opening 41 of a table 25 from an outlet opening 18 by gravity and the operation of the screw 4. In addition, along with successively moving the food by the screw 4, the food is lowered by gravity to the zone 12 of the channel 3 through the entrance opening 11 of the housing 2 from the opening 13 of the box 14 fixed upside down to the zone 12 of the housing 2 to replenish the food 15 to the housing 2. |
