Traditional Chinese medicine for increasing reproduction rates of giant salamander parents and feeding method

Abstract

The invention relates to a traditional Chinese medicine for increasing reproduction rates of giant salamander parents and a feeding method, belonging to the technical field of aquatic animal breeding. The traditional Chinese medicine is a powdery patent medicine prepared from the following single traditional Chinese medicine raw materials with the functions of reinforcing kidney to replenish essence, tonifying qi and spleen and promoting blood circulation to remove blood stasis in parts by weight: desertliving cistanche, China dodder, Chinese yam, Chinese magnoliavine fruit, plantain seed, Chinese angelica, prepared rhizome of rehmannia, radix polygoni multiflori praeparata, radix astragali, palmleaf raspberry fruit, dipsacus root, dried tangerine peel, asiatic cornelian cherry fruit, oriental waterplantain rhizome and barbary wolfberry fruit. The traditional Chinese medicine has the advantages that the synchronization of development of female and male gonads of the giant salamander parents is promoted by feeding the traditional Chinese medicine, thus substantially increasing the reproduction rates of the giant salamander parents; and by feeding the bait containing medicine for about five months, the reproduction rates of the giant salamander parents at sex-maturity ages are increased to above 60%, thus achieving large-scale reproduction of giant salamanders, promoting the process of industrialization and effectively protecting and multiplying the giant salamander resources.

Description

technical field [0001] The invention relates to a traditional Chinese medicine and a feeding method for improving the reproduction rate of giant salamander parents, belonging to the technical field of aquatic animal breeding. Background technique [0002] There are mainly three types of giant salamander reproductive models: [0003] 1. Original ecological reproduction mode: it is a species of salamander that reproduces naturally under natural ecological conditions. The disadvantages are: 1) The ability to resist natural disasters is weak: in an extremely severe weather environment, this model may be subject to a devastating blow in the same year, and it is difficult to achieve seedling emergence every year; 2) Natural enemies are seriously harmful: in the natural river for breeding The internal natural enemies cannot be eradicated, and the harm to fertilized eggs, immature salamanders, and juvenile salamanders is serious; 3) Inconvenient management: During the breeding pro...

AI Technical Summary

Problems solved by technology

The disadvantages are: 1) The ability to resist natural disasters is weak: in an extremely severe weather environment, this model may be subject to a devastating blow in the same year, and it is difficult to achieve seedling emergence every year; 2) Natural enemies are seriously harmful: in the natural river for breeding The internal natural enemies cannot be eradicated, and the harm to fertilized eggs, immature salamanders, and juvenile salamanders is serious; 3) Inconvenient management: During the breeding process, it is difficult to control the gonad development, egg laying and fertilization, hatching and emergence, and diseases of parent salamanders timely monitoring and treatment

Disadvantages are: 1) There are sometimes mutual predation and killing among giant salamanders; 2) To achieve large-scale breeding, the farm occupies a large area; 3) This model is mainly suitable for the cultivation of parent salamanders and seedling production, and is not suitable for commercial production. Feeding Giant Salamanders

Disadvantages are: 1) The cost of engineering facilities and temperature-regulating equipment for breeding is high, and the operating cost is high; 2) The technical requirements are high; 3) The reproductive life of parent salamanders is short, and it is necessary to continuously replenish the species of salamanders

Since the breeding conditions are all artificial environments, it is difficult to fully meet the ecological conditions and requirements for the gonad development of giant salamanders

In addition, due to technical level reasons, or improper hormone dosage, or improper injection timing, the parent salamander will die or be deformed.

[0006] The above three breeding modes have a common disadvantage, that is, the reproduction rate of salamanders is low, the highest is about 30%

In particular, the artificial reproduction of giant salamander needs to achieve large-scale, industrialization, and resource protection. The main constraint is the asynchronous development of the gonads of the female and male parents, which leads to a low reproduction rate.
