Captive breeding frogs Amphibian Conservation

A replicated study in 1992–1996 of Romer’s tree frog Chirixalus romeri at Melbourne Zoo, Australia and the University of Hong Kong (Banks, Lau & Dudgeon 2008) found that they bred successfully in captivity. Over 188 clutches of eggs were produced in Hong Kong in 1992–1996, 108 from wild and 76 from captive-bred females. Average juvenile mortality rate was 49% (range 31–71%). Five of 13 frogs survived until they were released to the wild five years after metamorphosis. Frogs in two terrariums died of red-leg syndrome. In Australia, seven egg clutches and 250 froglets were produced in 1991, with a froglet mortality rate of 83% at eight months. In 1992, 18 egg clutches (seven from wild and 11 from captive-bred females) and 530 froglets were produced. A total of 220 adults (150 males), 21 juveniles, metamorphs and tadpoles and seven egg clutches were collected from the wild in 1991–1992. Ten to 25 adults were housed per tank (60 x 30 x 30 cm). Tadpoles were raised in small tanks (up to six/100 cm2) and froglets transferred to tanks.
