Release captive-bred frogs
A before-and-after study in 1992–2000 in Jersey, UK (Racca 2002) found that released captive-bred agile frog Rana dalmatina tadpoles established a breeding population. The first egg mass was found in 1996, two years after the first release. Breeding also occurred in the release pond in 1998–2000. Mortality during the embryonic stage was 50% in captivity compared to 40% in the wild. One or two egg clumps were taken from the wild for captive breeding in 1992–1993 and 1997–2000. Captive-bred tadpoles were released into a pond in 1994–2000.
