Mauremys mutica hatching method

Abstract

The invention discloses a hatching method of Mauremys mutica. In propagation season, ventilate plastic box is taken as hatching box. Vermiculite layer of 3-6cm thickness is laid on the bottom of the hatching box as hatching medium. Fertilized eggs are put on the hatching medium with the space of 0.3-0.8cm, and then another layer of vermiculite of 2-3cm thickness is covered on the fertilized eggs. The humidity of the vermiculite layers in the whole hatching period is maintained 15 percent-20 percent, and the temperature in the whole hatching period is controlled 25-33 centigrade. Young tortoises are hatched 55-63 days. The invention adopts the vermiculite as the hatching medium, makes use of the preferable warmth retention property, moisture retention property and permeability of the vermiculite, improves the hatching success rate of the Mauremys mutica, shortens the hatching period and enhances the quality of newborn young tortoises.

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 quasi-water turtle, scientific name: Mauremys mutica Cantor1842, commonly known as stone turtle, water turtle, yellow turtle and fragrant turtle, English name: Yellow pond turtle, belongs to the order Turtles and Turtles, belongs to aquatic turtles, and is a breeding green-haired turtle The excellent turtles, yellow-throated aquatic turtles are rich in nutrition, and have high ornamental and medicinal value. In China, it is mainly distributed in Guangxi, Guangdong, Hainan, Fujian, Zhejiang, Jiangsu, Anhui, Taiwan and other places, and abroad in Vietnam and Japan. Due to the constraints of natural conditions, the hatching success rate of yellow-throated aquatic turtles has been relatively low in the wild. It has become an endangered species and has been included in the list...

AI Technical Summary

Problems solved by technology

[0003] The fecundity of yellow-throated aquatic turtles is low. In nature, a mature female turtle lays only a few eggs, and the success rate of hatching in the wild is very low; The average incubation time under the temperature is 73.8 days, and the hatching rate is only 84.2%. The Chinese invention patent discloses a "Yellow-throated aquatic turtle hatching method", the patent number is 200510121367.x, which uses sand as the hatching medium and cooperates with Proper temperature can greatly shorten the hatching period. When the hatching temperature is 32-34°C, the hatching period is 57-62 days. The development of the aquaculture industry of the species
