Embodiment Construction

[0020] The present invention will be further described and illustrated below in conjunction with specific embodiments.

[0021] Crocodile artificial propagation method provided by the invention adopts the following steps:

[0022] (1) Prenatal cultivation: From March to April, when the crocodile's estrus period comes, the mature female crocodile will be fed with more nutrition, such as chicken, pork, etc., and the feeding amount will be 1 / 3 of the crocodile's weight, once a day ; Supplement vitamins and calcium at the same time, such as vitamin E, vitamin A and vitamin D.

[0023] Strengthening nutrition is to provide nutritional guarantee for female crocodiles to conceive eggs, and at the same time increase the amount of eggs laid and the fertilization rate of eggs; generally, female crocodiles that lay eggs in the first year can lay about 20 to 30 eggs. , can lay 30-50 eggs, and this will be the case year by year; the fertilization rate of eggs is 50% in the natural state, ...

Abstract

The invention provides an artificial crocodile propagation method which comprises the following steps: (1) prenatal culturing; (2) mating; (3) preparing an incubator; (5) collecting eggs of the crocodile; (5) hatching; (6) deshelling; and (7) raising. The artificial crocodile propagation method improves the spawning rate of the crocodile, the fertility rate of the eggs up to 80-90%, the hatching rate above 90% and the survival rate approaching to 95%.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a method for changing the traditional natural breeding of crocodiles to artificial breeding. Background technique [0002] Crocodiles are rare animals in the world, with a life history of more than 200 million years. They are the earliest and most primitive reptiles that have not been discovered so far. They are known as "living fossils". They are widely distributed and have extremely high edible and medical values. . For example, crocodile meat, bones and viscera are rich in protein and various amino acids, fats, carbohydrates, vitamins and a variety of rare biological elements needed by the human body. immunity. In addition, leather goods made of crocodile skin are of high quality and high value, and are loved by people. [0003] At present, the total number of crocodiles raised in the world is only 2 million, mainly distributed in Southeast Asia. my country's Guangdong, Shanghai, ...
