[0002] Giant salamander (commonly known as giant salamander) is an ancient amphibian known as "living fossil". It is a national second-class protected animal. In order to protect and develop this precious resource and meet market demand, artificial breeding must be carried out, but it is difficult for male and female giant salamanders to synchronize Estrus, especially giant salamander sperm are very sen

Example Embodiment

[0007] The following are examples of the present invention.

[0008] Put each component in 1000 ml of distilled water, add sodium chloride (4400-4600 mg), sodium bicarbonate (190-210 mg), potassium chloride (130-150 mg), sodium dihydrogen phosphate (9-11 Mg) and calcium chloride (110-130 mg). Put the prepared sperm protectant in a special watering can and place it in a breeding pool to balance the temperature difference. Place the egg belt evenly on the bottom of the egg collection basin, and then evenly spray the sperm protectant prepared in the above optimal ratio on the egg belt, then pour the semen onto the egg surface, add physiological saline, and slowly rotate the egg collection Pots. The situation and effects of three different trials are listed below.

Abstract

The invention belongs to the field of fish breeding agents, and relates to a giant salamander sperm protecting agent. The giant salamander sperm protecting agent contains sodium chloride, sodium bicarbonate, potassium chloride, sodium dihydrogen phosphate and calcium chloride. When the protecting agent is used during artificial insemination of giant salamanders, the survival time of sperms can be prolonged by 7.7 hours; the activity of the sperms is obviously enhanced; and the fertility rate is improved by 27.3 percent.

Description

technical field [0001] The invention belongs to the technical field of fish farming and relates to a protective agent for giant salamander sperm. Background technique [0002] Giant salamander (commonly known as giant salamander) is an ancient amphibian known as "living fossil". It is a national second-class protected animal. In order to protect and develop this precious resource and meet market demand, artificial breeding must be carried out, but it is difficult for male and female giant salamanders to synchronize Estrus, especially giant salamander sperm are very sensitive to temperature, light and other environments outside the body, and the survival time is very short, making it difficult to achieve the purpose of artificial induction. Therefore, the reproduction of giant salamanders has not been able to make a major breakthrough, and the artificial breeding of commercial giant salamanders has also been stagnant. . There is currently no sperm protectant for giant salama...
