Amphibians: Identify and breed a similar species to refine husbandry techniques prior to working with target species

A small, replicated study in 2011–2012 of captive Scinax alcatrazin at São Paulo Zoo, Brazil, having developed methods using Scinax perpusillus (1), found that eggs were produced and juveniles maintained in captivity. The first breeding event occurred after 33 days in captivity. One female deposited around 140 eggs, of which 132 hatched. By July 2012, 93 froglets were still alive. Two males and a female died on the first day in captivity. Eleven animals (five males, three females, three tadpoles) were collected from the wild in October 2011 and housed in a biosecure room. Adults were kept in two glass enclosures, with plants and water. An ultra-sonic fogger was used to increase night-time humidity to stimulate breeding. Tadpoles were housed in a plastic enclosure and froglets in plastic cups. Management and husbandry protocols had been established over two years using captive Scinax perpusillus (see 1).
