Problems solved by technology

However, when we carried out the artificial reproduction of Chinese sturgeon, we found that when the semen was collected from the male fish, the abdomen of the fish would be squeezed repeatedly and continuously, which would easily cause damage to the fish body and lead to death

Embodiment 1

[0023] A non-invasive semen collection method for Chinese sturgeon. The sperm collection method is to place a Chinese sturgeon male fish on a sperm collection bed after anesthesia, first use absorbent paper to dry the water near the genital opening of the fish body, and then insert a silicone catheter through the genital opening. Insert 10-15cm into the fish body, place the sperm storage bottle at a position 20-30cm lower than the genital opening of the fish body, the semen in the fish will flow into the sperm storage bottle until there is no semen in the sperm storage bottle, and put the silicone hose from the fish After the semen collection is over, transfer the fish to a clear water pool for recovery to complete the semen collection.

[0024] Preferably, the anesthesia operation method specifically includes the following steps: configuration of the anesthetic: dissolving MS-222 into a watering can to prepare an anesthetic with a concentration of 100-120 mg / L; anesthesia: tra...

Embodiment 2

[0032] A non-invasive sperm collection device for Chinese sturgeon, which is composed of a deferens tube 1, a glass tube 2, an air outlet tube 3, a cork stopper 4, and a sperm storage bottle 5;

[0033] The deferens deferens tube 1 is a silicone hose with a length of 30-50cm and an inner diameter of 6-8mm;

[0034] The length of the glass tube 2 is 6-8cm and the outer diameter is 6-8mm. One end of the glass tube 2 is connected to the deferens deferens, and the other end is inserted into the glass tube hole of the cork stopper 4;

[0035] The air outlet pipe 3 is a glass tube with a length of 3-5cm and a diameter of 10-13mm, and one end of the air outlet pipe is inserted into the air outlet pipe hole of the cork cork;

[0036] The cork stopper 4 is a cylinder with a bottom diameter of 6-10cm and a height of 2-3cm, with glass tube holes and air outlet holes on it, the glass tube hole diameter is 6.1-8.1mm, and the air outlet hole diameter is 10.1mm. -13.1mm;

[0037] The sperm...

Abstract

The invention relates to a Chinese sturgeon noninvasive semen collection method which includes the steps: narcotizing a male Chinese sturgeon, placing the narcotized male Chinese sturgeon on a semen collection bed, and removing water approaching to a genital pore of the male Chinese sturgeon by absorbent paper; inserting a silica gel catheter into the male Chinese sturgeon to reach 10-15 cm from the genital pore, and placing a semen storage bottle at a position of 20-30cm lower than the genital pore of the male Chinese sturgeon; enabling semen in the Chinese sturgeon to flow into the semen storage bottle until complete semen flows into the semen storage bottle, drawing out the silica gel catheter from the genital pore of the male Chinese sturgeon, finishing semen collection, transferring the Chinese sturgeon into a clear water tank to perform restoring, and completing semen collection. The method can solve the problem death of the Chinese sturgeon caused by mechanical damage when the male Chinese sturgeon is repeatedly and continuously extruded, the postpartum survival rate of male Chinese sturgeon is remarkably increased, outer water can be prevented from entering the semen storage bottle, and absolute security of semen collection is ensured.

Description

[0001] The invention relates to the technical field of protection of rare and unique fish species, in particular to a non-invasive semen collection method and device for Chinese sturgeon. Background technique [0002] Chinese sturgeon is a migratory cartilaginous scale fish that is mainly distributed in the main stream of the Yangtze River and the southeast coast of my country. In the late 20th century, due to many factors such as overfishing, water conservancy construction, shipping, and water pollution, its wild population resources continued to decline. Although the Chinese sturgeon was listed as a first-class national aquatic protected animal in 1988, in the 19 years from 1981 to 1999, the supplementary population of Chinese sturgeon juveniles still decreased by about 90%. Therefore, the protection and research of Chinese sturgeon without delay. [0003] The Chinese Sturgeon Research Institute of China Three Gorges Corporation and several other scientific research institut...
