Artificially hatched turtles hatch hatchlings often because of improper temperature control. Hatched hatchlings are either male or female, which means that the difference is extremely small. Even female turtles are less than males, and wild turtles reproduce 3:1 males and females. The proportions are far from each Other. Due to the disruption of the balance between male and female under wild conditions, the rate of development of turtle colonies under artificial breeding conditions was limited.
In recent years, aquaculture workers have made progress in exploring the scientific principle of “incubation temperature determines genderâ€, which has increased the proportion of shelled turtles to varying degrees. After years of research and practice, it has been proposed that the optimal temperature control criterion for artificially hatching turtles to control sex is that most hatchling males hatchlings in the range of 20-27°C account for 93%-100% of the males, and At 30-35°C, almost all of the females hatched are female turtles; however, the American snapping turtles are an exception. Almost all females hatched at about 20°C and above 30°C are female turtles, and at 25--26°C Most males hatched under intermediate temperature conditions are males.
According to this standard, the author strictly controls the incubation temperature, and begins to reverse the passive situation in which the proportion of male and female hatched turtles has been severely misaligned due to the expansion of species in previous years. This has greatly improved the comprehensive economic benefits of turtles. (Deng Houqun, Laolin Soil Conservation Station, Yingshan County, Sichuan Postcode: 637730)
