Example Embodiment

[0011] The present invention will be further described below in conjunction with embodiments.

[0012] A method of artificial hatching and shaking eggs of giant salamander consists of the following steps:

[0013] 1) Fill the box with hatching sieve with water, then put the spawned giant salamander eggs into the hatching sieve and place them indoors for incubation. During the period, the water should be changed frequently to maintain the water quality, while controlling the water temperature and dissolved oxygen;

[0014] 2) Ten days before the hatching of the giant salamander eggs, the giant salamander eggs are shaken by hand in front and back, left and right, and up and down movements. During this period, the eggs cannot be exposed to the water, three times a day, each time for 2-3 minutes;

[0015] 3) When the giant salamander eggs hatch for ten to twenty days, insert the five fingers into the egg belt, and move the salamander eggs gently and slowly back and forth and left and right...

Abstract

The invention provides an artificial incubation egg-shaking method for giant salamanders. The artificial incubation egg-shaking method comprises the following steps that giant salamander eggs are placed in a box with an incubation sieve to be incubated, and the box is filled with water and is placed in an indoor environment; the giant salamanders are turned over three times in the front-back direction, the left-right direction and the vertical direction by a person with the hands, and the eggs cannot expose out of a water surface when turned over; when the giant salamander eggs are incubated for ten to twenty days, the person inserts five fingers in an egg band every 2-3 hours, and gently and slowly moves the giant salamander eggs in the incubation sieve in the front-back direction and the left-right direction, and the giant salamander eggs cannot be turned over; and the giant salamander eggs are naturally incubated until the giant salamander eggs are changed into giant salamander cubs. By the artificial incubation egg-shaking method, a mode of protecting eggs by male salamanders in the nature is imitated, the eggs are shaken artificially, the giant salamander eggs can slowly and stably move when incubated for ten to twenty days, so that the incubation survival rate of the giant salamanders is increased, and production and income are increased.

Description

technical field [0001] The invention relates to the field of artificial breeding of animals, in particular to an egg shaking method for artificial hatching of giant salamanders. Background technique [0002] With the sharp increase of commercial interests, at present, giant salamander breeding mostly adopts the method of artificial hatching for juvenile salamander breeding. In the process of artificial hatching of giant salamanders, due to the lack of scientific and reasonable methods and improper management methods, the reproductive rate of giant salamanders is generally low. At present, how to improve the survival rate of artificial hatching has become an urgent problem for giant salamander breeding enterprises. Contents of the invention [0003] In order to improve the survival rate of artificial hatching of giant salamanders, the invention proposes a method for shaking eggs of artificial hatching of giant salamanders. [0004] For this reason, the technical scheme of ...
