[0004] However, after the equipment takes out the fish sperm and eggs, it needs to be manually processed, and it is not convenient to process and mix the fish eggs and fish sperm by itself. Therefore, we propose an artificial insemination device that can protect the fertilized eggs of Pengze crucian carp and how to use it

The invention relates to the technical field of artificial insemination equipment for carassius auratus var pengze, and discloses an artificial insemination device with a protection effect on fertilized eggs of carassius auratus var pengze and a using method thereof.The artificial insemination device comprises a shell, an upper cover is fixed to the top end of the shell, a seminiferous duct is fixedly connected to the inner wall of the upper cover in a penetrating mode, a feeding opening is formed in the side wall of the shell, and an egg conveying hopper is fixed to the side wall of the feeding opening; a filter screen is fixed at the bottom end of the egg conveying hopper. According to the device, fish sperms are conveyed into the shell through the sperm conveying pipe, the stirring rod is driven by the motor to rotate slowly, the motor is a stepping motor, the stirring rod is made of an elastic rubber material, and therefore in the rotating process, fish eggs are prevented from being damaged, the fish eggs and the sperms are fully mixed and fertilized, after mixing is completed, the discharging opening is opened, and the stirring rod is driven by the motor to rotate slowly. The mixed ova flow into the feeding tank through the conveying plate, so that the effect of automatically mixing the fish sperms and the ova is achieved, the complexity of manual operation is reduced, and the device is more convenient to use.
Description
technical field [0001] The invention relates to the technical field of artificial insemination equipment for Pengze crucian carp, in particular to an artificial insemination device capable of protecting fertilized eggs of Pengze crucian carp and a method for using the same. Background technique [0002] Pengze crucian carp, also known as reed flower crucian carp or Pengze big crucian carp. Pengze crucian carp is native to natural waters such as Dingjia Lake, Taibo Lake, Fang Lake, and Yun Lake in Pengze County, Jiangxi Province. It is an excellent variety screened out after more than 7 years and 6 generations of careful breeding. It has the characteristics of fast growth, large individual, disease resistance and strong adaptability, and is an important aquaculture fish in my country. [0003] Chinese patent discloses: an artificial insemination device and artificial insemination method for barhead fish, patent application number: 202010216300.9, the patent "selects barhead...
