According to Akasay (1994), potential sources of “natural” feeds that could be cultivated as feed for frogs are fly larvae, earthworms, termites, duckweeds and snails. Earthworms are appropriate elements in systems of recycling live stock manure (Bay, 2002), as they are more suitable than biodigesters when the manure is derived from rabbits and goats (Preston and Rodríguez, No date). Earthworms are high in protein and would thus appear to be suitable components in a feeding system for frogs.

Fly larvae have been recommended as feed for frogs by Sheppard (No date), as they are rich in both fat and protein (Khan et al 1999).

The objectives of the study were to compare the growth of frogs fed with fly larvae or earth worms as part of an integrated farming system. The hypothesis was that frogs can grow at acceptable rates when their diet is composed primarily of earthworms or fly larvae.
