Method of tadpoles in a closed system with filtration

Abstract

Considering the need to differentiate tadpoles by species, and by stage of development, and to consolidate the preservation of the largest number of stages in herpetological collection, the collection of tadpoles and maintenance in aquarium until metamorphosis is common for final identification of its species. For this purpose, the present work aimed at creating a low-cost method for maintaining tadpoles in the laboratory that would minimize the space used and facilitate maintenance. Plastic organizers were used as aquariums, interconnected by closed water circuits with filtration. During a 21-day test, tadpoles of Leptodactylus macrosternum showed maximum mortality of 9% with this breeding method.
