Example Embodiment

[0009] Example 1,

[0010] (1) Construct a breeding room and a breeding pond group with imitating natural ecological function located in the breeding room. The pool group includes two side-by-side rearing ponds, the size of the rearing pond is 1.2m in length×0.6m in width×0.8m in depth. There is a partition wall between the pools, the height of the partition wall is 0.8m, and the height above 1 / 3 is a fence; one pool of this pool group is put into female giant salamanders, and the other pool is put into male giant salamanders; the stocking density of giant salamanders in the above pools is 1 fish / m 2 ; Pebbles with a diameter of ￠1cm are laid on the bottom surface of the inner cavity of the breeding pool. Put water into the pool, and the conventional method keeps the water in the weak flowing state, and the conventional method keeps the sound effect of the pool water imitating the ding-dong sound of cave spring water. Open windows on the wall of the breeding room, every 8~10m ...

Example Embodiment

[0013] Example 2,

[0014] (1). Construct 2 breeding rooms, each of which is equipped with 2 imitating natural ecological function breeding pool groups. Each pool group includes 3 side-by-side rearing ponds, the size of the rearing pond is 2.0m in length×1.2m in width×1.1m in depth. There is a partition wall between the pool and the pool, the height of the partition wall is 1.1m, and the height above 1 / 3 is a fence; male giant salamanders are placed in the middle pond of the pool group, and female giant salamanders are placed in the rearing ponds on both sides. The stocking density of giant salamanders in the above ponds is 2 fish / m 2 ; Pebbles with a diameter of ￠3cm are laid on the bottom surface of the inner cavity of the breeding pool. Put water into the pool, and the conventional method keeps the water in the weak flowing state, and the conventional method keeps the sound effect of the pool water imitating the ding-dong sound of cave spring water. Open windows on the wall ...

Abstract

The invention introduces a method for improving the reproduction rate of giant salamanders, which includes the following steps: (1) building up an artificial natural ecological function culture system, namely, at least one artificial natural ecological function culture pond group, wherein each pond group comprises 2-3 rearing ponds; (2) feeding qualitatively and quantitatively at fixed time, wherein live loaches or crucians are taken as the main feed, fresh shrimps and beef liver or pork liver are added as auxiliaries, furthermore as for male salamanders, testes of cocks or ducks are added, and as for parent salamanders, vitamin C or vitamin E are added before and after the parturition; and (3) regulating and controlling the water temperature, wherein at the temperate range of 17-19 DEG C, the female salamanders and the male salamanders can be enabled to grow up at the same time by rising or lowering the water temperature by 1-2 DEG C. The method can greatly improve the artificial reproduction rate of giant salamanders, with the induced spawning rate of the female salamanders reaching 75% and the male salamanders exceeding 80%. Meanwhile, the method can also improve the fertility rate and the hatching rate by 8-12%.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for increasing the reproductive rate of giant salamanders. Background technique [0002] Giant salamander, commonly known as giant salamander, is the largest individual among the existing amphibians. It is a unique species and is a national Class II protected animal in my country. It has extremely high economic value and scientific research value. The research on artificial breeding technology of giant salamander is very extensive, but most of them are limited to the research of a single factor, and the research results are not satisfactory, which makes the reproductive rate of giant salamander, including the rate of induction, fertilization rate, hatching rate, etc., very low all the time. Therefore, it is difficult to realize large-scale production. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a metho...
