A kind of traditional Chinese medicine and feeding method for increasing the ginseng reproduction rate of giant salamander parents

Abstract

The invention relates to a traditional Chinese medicine and a feeding method for increasing the ginseng reproduction rate of giant salamander parents, belonging to the technical field of aquatic animal breeding, and is mainly prepared in parts by weight from single Chinese medicine raw materials such as invigorating the kidney and replenishing essence, nourishing qi and invigorating the spleen, and promoting blood circulation and removing blood stasis The resulting powdered medicines include: cistanche, dodder, yam, schisandra, plantain, angelica, rehmannia root, Zhishouwu, astragalus, raspberry, chuanduan, tangerine peel, jujube peel, alisma, medlar. The advantages of the present invention are: by feeding the traditional Chinese medicine of the present invention, the synchronization of the male and female gonads of the giant salamander parents is promoted, thereby greatly increasing the reproduction rate of the giant salamander parents, and feeding the medicated bait for about 5 months, and the giant salamander parents reaching the age of sexual maturity The ginseng reproduction rate has been increased to more than 60%, realizing large-scale reproduction of giant salamanders, promoting the process of industrialization, and effectively protecting and multiplying 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 proc...

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 shortcoming, that is, the reproduction rate of parent 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.
