Captive breeding toads
A small, replicated study in 1981–1984 of captive natterjack toads Bufo calamita in Norfolk, UK (Jones 1984) found that two egg strings were produced by nine females. These hatched successfully. The majority of the tadpoles were released back to the wild. In the first year only one of nine wild toadlets survived overwintering in captivity and died shortly after. The following year all 25 wild tadpoles survived to adulthood. In 1981, 12 and in 1982, 25 tadpoles were collected from the wild. Toadlets were housed in a tank with water, a sloping sandy substrate and moss. In the first year toadlets were housed outdoors, after that all tadpoles were kept indoors for at least their first year. Adults were housed in an outdoor enclosure with sandy substrate, a pool, wood and heathland plants.
