Embodiment 1

[0011] The sex control method of Chinese soft-shelled turtle of the present embodiment is carried out in the soft-shelled turtle hatching room. Fertilized eggs were collected in June, and collected 24 hours after spawning, when the fertilized spots were already very obvious. Eggs with clear fertilization spots are selected and placed evenly in hatching wooden boxes, and then the eggs are placed in different small hatching rooms. The hatching rooms have independent ventilation, temperature control, humidity control and other facilities. The hatching substrates are as follows: the hatching substrate of soft-shelled turtle eggs is fine sand with a particle size of 0.5mm-0.6mm.

[0012] The hatching temperature of soft-shelled turtle eggs is set at 26°C, 28°C, 30°C, and 32°C, the relative air humidity in the hatching room is 75%-85%, the water content of the sand bed is 7%-8%, and 100 eggs are placed in each hatching room. Fertilized eggs were hatched, a total of 400 pieces; at t...

[0017] The hatching temperature of soft-shelled turtle eggs was set at 30°C, the relative air humidity in the hatching room was 75%-85%, and the water content of the sand bed was 7%-8%. Six test groups were set up for the experiment, and each group was treated with methyl testosterone drops. On the anima...

Abstract

The invention discloses a sex control method for Chinese soft-shelled turtles, which includes: firstly, controlling the incubation temperature to be from 23 DEG C to 35 DEG C; and secondly, dropwise adding methyltestosterone to an animal pole of each fertilized egg. By means of temperature control and application of the methyltestosterone, the sex control method evidently increases a male proportion of Chinese soft-shelled turtles and meets market requirements.

Description

technical field [0001] The invention relates to a method for sex control of Chinese soft-shelled turtle. Background technique [0002] Turtle is a traditional high-grade nourishing aquatic product in my country and an important species of aquaculture, which plays a decisive role in the rural economy of our province. In the long-term breeding practice of soft-shelled turtles, it has been found that there are great growth differences between male and female individuals. Growth characteristics of soft-shelled soft-shelled turtles: Male soft-shelled turtles grow significantly faster than female soft-shelled turtles. According to experiments, male soft-shelled soft-shelled turtles grow 12.7%-17.0% faster than female soft-shelled turtles in groups with an average weight of 300g. The growth difference between male and female soft-shelled turtles will further increase, and consumers prefer to eat male soft-shelled turtles. Not only are male soft-shelled turtles best-selling, but th...
