Breed reptiles in captivity: Snakes – Colubrids
A study in 1983–1986 at Dallas Zoo and Fort Worth Zoo, USA (Cover & Boyer 1988) reported that San Francisco garter snakes Thamnophis sirtalis tetrataenia bred successfully in captivity. In 1984–1986, three females produced six broods of 9–35 young/brood, following gestation periods of 79–98 days. Six young died or had to be put down within four months of birth. The male to female sex ratio of broods ranged from 19:16 to 5:12. Snakes were housed in plastic show boxes, 1 gallon glass jars or 5 gallon aquaria (36 x 22 x 26 cm) with a paper substrate and plastic hide boxes, bark and plastic leaves. Ambient temperatures were 27–30°C at Dallas Zoo and 21–32°C at Fort Worth Zoo, and spotlights provided basking spots at 32°C for gravid females.
