  1. Relocate nests/eggs for artificial incubation: Tortoises, terrapins, side-necked & softshell turtles

    A study in 1985–1986 at Columbus Zoo, Ohio, USA (Goode 1988) found that two of three incubated eggs laid in captivity by a wild-caught gravid gibba turtle Mesoclemmys gibba hatched successfully. A female laid three eggs over a one-month period, and two hatched successfully after 154 and 164 days of incubation. The third egg failed during incubation. A wild-caught female was acquired in 1985 and housed along with a range of other turtle species in a 140 cm square display tank, with 50 cm deep water and a basking spot. Water temperature was 20–24°C and air temperatures were 24–32°C. Eggs were incubated at 26–31°C in sealed 1 gallon jars in a 1:1 mixture of vermiculite and water (by weight), and jars were vented every 4–6 weeks.

  2. Breed reptiles in captivity: Tortoises, terrapins, side-necked & softshell turtles

    A study in 1977–1986 at Columbus Zoo, Ohio, USA (Goode 1988) found that gibba turtles Mesoclemmys gibba reproduced successfully in captivity. In 1978–1982, one female produced seven clutches of 3–6 eggs. In 1985–1986, a further three females produced seven clutches of 2–7 eggs. Two of these females were offspring of the first pair. Incubation periods ranged from 140–248 days. The original male was acquired in 1968, and a female was acquired in 1977. Adults were housed along with a range of other turtle species in a 140 cm square display tank, with 50 cm deep water and a basking spot. Water temperature was 20–24°C and air temperatures were 24–32°C. Eggs were incubated at 26–31°C in sealed one-gallon jars in a 1:1 mixture of vermiculite and water (by weight), and jars were vented ever 4–6 weeks.
