Device and method for hatching embryos of Chinese softshell turtles

Abstract

The invention relates to a device and method for hatching the embryos of Chinese softshell turtles. The device comprises an incubator, an incubation plate and a collecting box and is characterized by further comprising a temperature sensor, a humidity sensor, a temperature control device, a humidifying device and a ventilation device. After the device is adopted, fertile eggs can be automatically hatched in a completely naked state; the device is high in hatching efficiency; and the defects that the fertile eggs are mildewed, the embryos die and the like caused by medium incubation in the prior art can be avoided.

Description

technical field [0001] The invention relates to a hatching device and method for soft-shelled turtle embryos. Background technique [0002] Chinese soft-shelled turtle is a famous and precious aquatic product loved by Chinese people. With the improvement of people's living standards, the market prospect of Chinese soft-shelled turtle is promising, and its artificial hatching and artificial breeding technology has always been a research and development hotspot in this field. [0003] The traditional artificial hatching method of Chinese soft-shelled turtle is to simulate the natural hatching conditions of Chinese soft-shelled turtle embryo. for incubation. When hatching in batches, the hatchery first needs to select a suitable moisturizing medium, and clean and disinfect the selected moisturizing medium. At the same time, the moisturizing medium needs to be cleaned and disinfected regularly during the hatching process. Because the eggs are covered under the moisturizing med...

Problems solved by technology

This is because wet towels and water vapor from the water in the water box are used to provide the humidity required for incubation. Fertilized eggs are incubated for a long time under high temperature and high humidity conditions, and water droplets form on the surface of the fertilized eggshell, which is not conducive to the incubation of eggs. Embryo respiration is very easy to breed bacteria, moldy and smelly; moreover, during the incubation process, the incubator should be opened every day, and the gauze should be replaced and moistened 1-2 times, which will easily move the fertilized eggs during operation, which is not conducive to normal embryonic development , the survival rate is low; in addition, the fertilized eggs covered by a wet towel have no ventilation holes around the positioning hole, the gas flow in the box is not smooth, and the temperature and humidity control is uneven. Therefore, in practice, the hatching rate using this method is only 30~40%, lower than the method using moisturizing medium
