Simulative original ecology breeding method for giant salamanders

Abstract

Disclosed is a simulative original ecology breeding method for giant salamanders. The original ecology breeding method comprises: 1) simulative original ecology breeding pool building: the length of a simulative original ecology breeding pool is usually between 30 meters and 50 meters, the width is between 0.8 meter and 1.5 meters, and the pool depth is in a range of 0.4 meter to 0.6 meter; 2) simulative original ecology breeding cave building: the length, width and height of the cave opening is in a range of 20cm to 30cm, the cave length is between 0.8 meter and 1.2 meters, the width is between 0.8 meter and 1 meter, and the height is between 0.3 meter and 0.4 meter; and 3) giant salamander parent breeding. The simulative original ecology breeding method has the advantages that the simulative original ecology breeding is not only large in spawning amount and high in fertility rate, but also high in hatchability. The average young salamander birthing amount of each pair of giant salamander parents is between 800 and 2000. The natural spawning fertilization and hatching time of simulative original ecology breeding is as long as 108 days, and the number of the birthed fry is 1500.

Description

technical field [0001] The invention relates to the field of giant salamander imitation original ecological breeding method. technical background [0002] Giant salamander (also known as giant salamander) The artificial reproduction technology of giant salamander is still in the experimental stage. The artificial reproduction rate of giant salamander is low. What are the problems? We conclude with the following questions: [0003] (1). The development of female and male glands is not synchronized, which is due to water temperature and bait, because water temperature and bait are the decisive factors for the development of giant salamander gonads. [0004] (2). A large number of eggs laid by the female cannot be fertilized, commonly known as dead eggs, which shows that the eggs have not yet reached the physiological and morphological maturity of fertilization. The eggs laid by female salamanders are not less than 50,000-300,000 eggs per year. In fact, each company breeds o...

AI Technical Summary

Problems solved by technology

[0004] (2). A large number of eggs laid by the female cannot be fertilized, commonly known as dead eggs, which shows that the eggs have not yet reached the physiological and morphological maturity of fertilization

[0005] (3). Female dystocia is common

[0006] (4). Poor quality of male semen

According to the theory of traditional Chinese medicine, the poor quality of semen is due to insufficient kidney qi, loss of kidney yang, and insufficient metaplasia, which lead to the decline of essence qi, loss of body liver, and poor qi and blood are the root causes of dead sperm; The water environment with low temperature and dark light has a great correlation. Giant salamanders living in cold and dark water environment are the factors that cause deficiency of kidney qi and kidney yang, resulting in dead sperm and low vitality of giant salamanders.

Some researchers use fish sperm nutrient solution to improve the sperm quality of giant salamanders, but the effect is very small. As everyone knows, because giant salamanders lack spermatogenic protein, that is to say, the sperm is congenitally deficient, and the effect of using fish sperm nutrient solution to improve the sperm quality of giant salamanders is not good. is predictable

The above problems boil down to the fact that there is no special phytoplankton in the pond that is suitable for the development of the gonads of giant salamanders; that is, there is not enough amino acid, and the giant salamanders are congenitally stunted, so the quality of male sperm is poor and their motility is low.

[0007] (5). A large number of embryos are prone to die in the late stage of fertilized egg development

[0008] (6). Large number of deformities in juvenile salamanders

[0009] (7). It is difficult to artificially select sexually mature parent salamanders

[0010] There are deficiencies in the existing method of imitating original ecology (CN101081008), mainly because there is no light regulation in the pool, and there is no cultivation and maintenance of navicula and ovale in the pool method, the water flow lacks a certain velocity
