The apparatus includes a plurality of containers, within which frogs are cultivated, supported in vertically spaced tires on an upright rack. A plurality of feed trays are provided wherein a feed tray is provided for each container. Artificial feed, in the form of a plurality of pellets, or discrete feed particles, are supplied in the feed tray. An air suction system is utilized for engagement of the discrete particles. Air is drawn through a feed engagement member so a suction force is created at the tip of the feed engagement member to engage pellets. The feed engagement member is actuated toward the feed tray to engage the pellets. Then the feed engagement member is actuated to the interior of the container where the frogs take the pellets off of the feed engagement member. The air flow direction can, in the air suction system, also be reversed so air is blown out through the feed engagement member in order to clean the same and any conduits or lines leading to the feed engagement member.

A feed trough is provided for use in cultivation containers for growing frogs and other amphibians. The feed trough is comprised of a sloped floor. In some embodiments the floor slopes downward to an opening from which, during operation, airflows. The opening is covered by a perforated cover that retains the feed particles collected from the sloped floor and provides sufficient opening for airflow that propels the feed particles from the perforated cover into the airspace of the cultivation container.During operation, airflow passes through the opening with sufficient force to suspend in the air feed particles that have rolled along the sloped floor, or fallen, onto the perforated cover covering the opening. The movement of the feed particles in the air stimulates feeding by the frogs or other amphibians. Feed that is not consumed falls onto the sloped floor, rolls onto the screen or wire mesh covering the opening, and is resuspended by the airflow. The airflow may be continuous, intermittent, or otherwise programmed.The air of the airflow may be heated. This serves to dry feed particles that have become moistened, increase ambient temperature to increase growth rates, and/or dry the cultivation container.In other embodiments a vibrational force is applied to move feed particles to simulate live feed, to stimulate feeding.

A system and method for commercially raising frogs in a controlled environment is disclosed. The frogs are housed within a plurality of containers stacked in an array within the spaced tiers of a rack. Each container defines a first and second chamber and a ledge about the periphery of the container for suspending one or more panels above the chamber to form a third elevated chamber within the container and is fitted with a screen to prevent the frogs from escaping. Ramps provided within each chamber enable the frogs to travel between chambers and to access the third chamber. When adult frogs are being cultivated in the containers, the first chamber of each container retains water to provide an aquatic habitat for the adult frogs, and the second chamber remains dry. When frogs are being cultivated in their larval form as tadpoles within the containers, both the first and second chambers retain water to maximize the aquatic habitat for the tadpoles. Water is retained within each chamber by a stand pipe connected to a drain in the bottom of each chamber. The water within the chambers is continuously circulated by providing a constant supply of water to one or both of the first and second chambers of the uppermost container in the rack. As the water level exceeds the height of the stand pipe within each chamber, the water flows over the stand pipe and through the drain to the corresponding chamber of the container spaced below in the rack. Water passing through the drain in the chamber of the lower most container in the rack is captured by a drainage system positioned beneath the rack. A feeder can be mounted within each container to automatically discharge feed for the frogs. In addition, an access slot in the lid of each container provides access to the chambers for grading and separating the frogs as they develop, and for cleaning the chambers.
