[0045] Since the temperature of the spring water is relatively constant, the control method of combining the original ecological river course and the spring water is adopted to achieve the technical effect of controlling the water temperature of the giant salamander aquaculture during the breeding period (late August to mid-September). In actual operation, automatic control or manual control can be adopted. When manual control is used, the water temperature of the giant salamander breeding water is monitored every 2 hours, and the water temperature is controlled between 15-22°C or preferably between 18-22°C or kept at 15-22°C by adjusting the water intake of the original ecological river course and spring water respectively. Any temperature value between ℃. Compared with the hatching and hatching period at this constant value, every time the temperature is increased by 1°C and kept constant, the hatching and hatching period will be advanced by 1 to 2 days before the change; co...

The invention provides a method for intervening reproduction of giant salamanders. Reproduction of the giant salamanders is intervened under the premise that health of the giant salamanders is not damaged through a physical means, and the technical problem of damage to the health of the giant salamanders due to the fact that a drug means is adopted to intervene reproduction of the giant salamanders in the prior art. The method includes under the premise that water temperature meets 14-25 DEG C, spermiation period of male giant salamanders and / or spawning period of female giant salamanders is intervened by adjusting PH value of water for breeding the giant salamanders. The spermiation period of male giant salamanders and / or the spawning period of female giant salamanders is intervened by the physical means of adjusting the PH value of the water for breeding the giant salamanders, so that predictable reproduction of the giant salamanders through artificial breeding is realized, the health of parent fishes of the giant salamanders is not damaged, and multi-year continuous reproduction of the parent fishes can be realized. Breeding personnel can allow the giant salamanders to perform reproduction at a proper time through the above technical scheme, so that economic loss caused to artificial breeding due to the fact that the giant salamanders produce in improper growing environment and at improper time is avoided.
Description
technical field [0001] The invention relates to the technical field of artificial breeding of giant salamanders, in particular to a method for interfering with the reproduction of giant salamanders. Background technique [0002] Giant salamanders, commonly known as giant salamanders and salamanders, belong to the order Cryptobranchidae and are national second-class protected animals. At present, the artificial breeding of giant salamanders has achieved remarkable economic and social benefits, and has become an economic means for farmers to increase their income. Since the giant salamander is a temperature-changing animal, the suitable temperature for its embryonic development is roughly distributed between 14 and 25°C. In the prior art, the output of artificially cultured giant salamander will be affected by the external ambient temperature, and the output of the breeding base is highly dependent on the local climate. The external ambient temperature is consistent with the w...
