Ecological breeding method for giant salamanders

Abstract

The invention relates to an ecological breeding method of giant salamanders. The ecological breeding method comprises the following steps of: damming to store water by utilizing a mountain stream or groundwater resources; establishing a plurality of small caves in each block below the area which is dammed to store water, introducing the mountain steam or groundwater in the dam to each block and keeping the mountain steam or groundwater to flow without recycling; enabling the water temperature of the water flowing in the blocks to be lower than or equal to 25 DEG C by adopting a refrigerating machine when the water temperature or the gas temperature exceeds 25 DEG C; adding fresh live baits which can be eaten by breeding giant salamanders in the area which is dammed to store water, enabling the fresh live baits to naturally flow to the blacks for the giant salamanders to eat; enabling the seed giant salamanders to naturally get mature in the blocks, naturally mate and lay eggs; manually moving the eggs out of the blocks after the egg laying, hatching and enabling the eggs to grow maturely. The ecological breeding method of giant salamanders has the original ecology characteristic, so that the natural instincts of the giant salamanders are not retrograded, the incidence of a disease of the breeding giant salamanders is less, the breeding giant salamanders get mature naturally, synchronously grow and naturally lay eggs, and therefore, the reproductive life of the breeding giant salamanders is greatly prolonged and the breeding survival rate is high.

Description

technical field [0001] The invention relates to an ecological breeding method for giant salamanders. Background technique [0002] Giant salamanders are commonly known as "salamanders". At present, there are two methods of breeding giant salamanders. One is to use natural streams to stock them, that is, to build dams in the downstream of the stream and to stock them naturally in the upper reaches. Once a giant salamander gets sick in this method, it will affect a large number of giant salamanders and cause a large number of giant salamanders to die. Moreover, the mating of the breeding fish is carried out out of order, and the same species will be killed during the estrus period, which will cause the breeding fish to be more disabled. Therefore, the survival rate of the breeding is very low; the second is to artificially build a basement or use a cave for breeding, and use artificial insemination and fertilization. However, the disadvantage of this method is that the life s...

At present, there are two methods of breeding giant salamanders. One is to use natural streams to stock them, that is, to build dams in the downstream of the stream and to stock them naturally in the upper reaches. Once a giant salamander gets sick in this way, it will affect a large number of giant salamanders and cause a large number of giant salamanders to die. Moreover, the mating of the breeding fish is carried out out of order, and the same species will be killed during the estrus period, which will cause the breeding fish to be more disabled. Therefore, the survival rate of the breeding is very low; the second is to artificially build a basement or use a cave for breeding, and use artificial insemination and fertilization. , the disadvantage of this method is that the life span of the species of fish is short, and it will degenerate in 2 to 3 years, which consumes a lot of water.
