  1. Release captive-bred frogs

    A replicated study in 2012 of southern corroboree frogs Pseudophryne corroboree at Taronga and Melbourne Zoo, Australia (McFadden 2012) found that a high proportion of captive-bred frogs that were released as eggs reached metamorphosis and exited the ponds. Over 750 eggs were released into ponds at three remote sites. Captive breeding was undertaken as fewer than 50 individuals remained in the wild, mainly because of chytridiomycosis.

     

  2. Captive breeding frogs

    A replicated study in 2011–2012 of captive southern corroboree frogs Pseudophryne corroboree at Taronga and Melbourne Zoo, Australia (McFadden 2012b) found that frogs reproduced successfully in captivity. Having had difficulties breeding the species in the first years of the programme, captive breeding protocols had been established that resulted in high reproductive success. In 2011 and 2012, the majority of mature females produced eggs. Eggs were separated and observed during early development. Captive breeding was undertaken as less than fifty individuals remained in the wild, mainly because of chytridiomycosis.
