  1. Breed reptiles in captivity: Snakes – Colubrids

    A study in 1968–1976 at Dallas Zoo and Fort Worth Zoo, USA (Tryon 1976) reported that wild-caught trans-pecos ratsnakes Elaphe subocularis and their captive-born offspring reproduced successfully in captivity. In 1973, a wild-caught female produced a clutch of six eggs following five years in captivity. Five of six eggs hatched successfully after an incubation period of 105 days. A female from this clutch produced a clutch of three eggs in 1975, and a clutch of four eggs in 1976. All seven eggs hatched successfully following incubation periods of 73–76 days. In 1968, an adult pair of snakes was acquired by Dallas Zoo. Two offspring from this pair were given to Fort Worth Zoo, where they were housed together in a 3-foot fibreglass cage with a pea gravel substrate, rocks and plastic plants. Eggs were removed and incubated in sealed 1 gallon jars in a medium of vermiculite and water (4 oz to one fluid oz water). Jars were opened at two-week intervals to replenish oxygen levels and temperatures were maintained at 28–32°C.
