How to hatch crocodile eggs artificially

When hatching hatchlings in artificially raised turtles, due to improper temperature control, the hatched hatchlings are either half male or half male, or the hatchlings have very small differences. There are even fewer female turtles than male turtles. Compared with wild turtles, the ratio of male to female offspring is about 3:1. The proportions are very different. Because it destroys the balance of male and female ratio in wild conditions, it limits the speed of turtle population development in artificial breeding conditions.

In recent years, aquaculture workers have made progress in exploring the scientific principle of "incubation temperature determines gender", which has improved the proportion of turtles hatching to varying degrees. After years of research and practice, some people have proposed the best way to control the gender of artificially hatched turtles. The optimal temperature control standard is: for most turtles, 93%-100% of the hatchlings hatched in the 20-27℃ range are male, while almost all of the hatchlings hatched in the 30-35℃ range are female.

But the American snapping turtle is an exception. Almost all turtles hatched at around 20℃ and above 30℃ are female turtles, while most turtles hatched at the intermediate temperature of 25-26℃ are male turtles.

Based on this standard, the author strictly controlled the incubation temperature and began to reverse the passive situation of serious imbalance in the male and female ratio of hatched turtles caused by the expansion of breeding and breeding in previous years, greatly improving the comprehensive economic benefits of turtle breeding.
