Is Chongqing suitable for raising crocodiles?

Chongqing is suitable for raising crocodiles.

1. If you want to raise crocodiles, you should choose a site to build crocodile ponds, aquaculture ponds and other infrastructure according to the scale you want to raise. The project report should be sent to the local fisheries bureau, land and resources bureau, industrial and commercial administration and other relevant departments for approval. After the address is selected, it is necessary to sign a written agreement with the collective organization of the village Committee whose land has been requisitioned with the help of the local government department, and the infrastructure can only be started after all the procedures are complete.

2. Breeding reptiles, such as crocodiles, can make a transition from aquatic to terrestrial life due to the appearance of chorionic eggs. The male and female identification of crocodiles can be judged by the shape of scales and connectors in cloaca. Male scales are thick and small, while female scales are thin and large. The cloaca is triangular, and the crocodile with a red rod-shaped connector inside is male, while the short and pale crocodile is female. The sexual maturity of crocodiles is late, all of which are over 3 years.

Crocodiles are usually separated, mating once a year in the breeding season and mating in water. After mating, female crocodiles use weeds, leaves and so on. To build a nest, climb to the top of the nest when they are in labor, dig a hole in the middle and lay eggs in the hole. 2 ~ 3 days before laying eggs, female crocodiles will have severe fetal pain and tears will flow like a note. The number of eggs laid is 20-30, or up to 70. Elliptical spherical eggs are similar to goose eggs, weighing 50-200 grams, and the incubation period is 2-3 months.

4. There are two special differences in the reproductive characteristics of crocodiles. One is the caring behavior of relatives. Secondly, the hatching temperature controls the sex of young crocodiles. Both female crocodiles and male crocodiles have parental care behaviors, which are embodied in protecting eggs, digging nests, carrying and luring young crocodiles into the water and protecting young crocodiles. The sex of young crocodiles is generally determined by the incubation temperature, and the incubation period is 30 ~ 45 days, which is a heat sensitive period. The offspring hatched in the range of 28 ~ 3 1.5 degrees are all females, the male rate of the offspring hatched in the range of 32 degrees has soared to 66%, and the young crocodiles hatched in the range of 32.5 ~ 33 degrees are all males. The weather in Chongqing is very suitable for raising crocodiles.
