Problems solved by technology

The fecundity of the yellow-throated aquatic turtle is low. In nature, a mature female turtle lays only a few eggs. At the same time, the success rate of hatching in the wild is very low, which seriously restricts the recovery of its natural resources and restricts the species. Development of aquaculture

Embodiment Construction

[0010] In the breeding season, a ventilated plastic box is used as an incubator, and sand particles with a diameter of 0.3 to 0.6 mm are loaded as the hatching substrate. The grains of sand are exposed to sunlight before hatching. Spread 5cm thick sand on the bottom of the incubator, put in fertilized eggs, every 100CM 2 Put 2-3 fertilized eggs, cover 2cm sand layer, and keep the water content of the hatching sand bed at 5-10% throughout the incubation period. The incubator is placed in an electrically heated constant temperature incubator, and the temperature is controlled by the constant temperature incubator. Insert a mercury thermometer at 2 cm from the sand layer of the incubator, and use this mercury thermometer as the standard to control the hatching temperature during the hatching period.

[0011] When the temperature is controlled at 28-30°C, the eggs will hatch into hatchlings after 65-70 days. At this time, the hatching success rate is the highest, the survival r...

Abstract

The invention discloses a method of hatching Yellow throat quasi-water tortoise, in the breeding season, employing ventilating plastic box as hatching box, laying a 3-6cm -thick sand grain layer on the box bottom as hatching base material, putting the fertilized ovum into the box, 2-3 fertilized ovum for every 100cm2, covering a 1-3cm-thick sand grain layer, the water content of the hatching bed during the whole hatching period is maintained 5-10%; and the temperature is controlled in 28-30 Deg C, then getting the infant tortoise with balanced sex ratio after 65-70 days later. The invention can increase the success rate of hatching Yellow throat quasi-water tortoise, and the survival rate of the infant tortoise.

Description

technical field [0001] The invention relates to a method for hatching aquatic animals, in particular to a method for hatching yellow-throated aquatic turtles. Background technique [0002] Yellow-throated terrapin (Mauremys mutica Cantor 1842) is commonly known as stone turtle, stone money and fragrant turtle. Taxonomically, it belongs to the order Turtles, Turtleidae, and Pseudowater Turtles. In China, it is mainly distributed in Guangxi, Guangdong, Hainan, Fujian, Zhejiang, Jiangsu, Anhui, Taiwan and other places, and abroad in Vietnam and Japan. However, its natural resources are limited, and it has become an endangered species. It has entered the list of Appendix II of the "Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)" and is also one of the aquatic animals protected in Guangdong Province. It has gradually attracted people's attention in recent years. The fecundity of the yellow-throated aquatic turtle is low. In nature, a mat...
