ABSTRACT:
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.
