Head-start amphibians for release
A replicated study in 1978–1979 of Houston toads Bufo houstonensis at Houston Zoo, USA (Quinn 1980) found that tadpoles were raised successfully from eggs, but problems were encountered raising adults. Mortality rates of tadpoles were 5–9%. Several experimental groups under different conditions demonstrated that toads raised in naturally planted outdoor enclosures grew faster and had significantly higher survival rates than those raised indoors.
