Abstract: 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.

Abstract: 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.
