Giant salamander breeding pond

Abstract

The invention relates to the technical field of breeding devices and particularly discloses a giant salamander breeding pond. The giant salamander breeding pond comprises a breeding pond body, whereina separation net is arranged in the middle of the breeding pond and divides the breeding pond into a hatching zone and a growth zone, a hatching bucket is arranged in the hatching zone, the bottom ofthe hatching bucket is hinged to a mounting base, a water draining pipe horizontally penetrates through the bottom wall of the hatching bucket, and air bags are uniformly distributed in the hatchingbucket. The giant salamander breeding pond also comprises a stirring bucket, wherein a piston is slidingly connected in the stirring bucket, a through hole is vertically formed in the piston, a pistonrod is connected to the top of the piston, the piston rod is in threaded connection with the top of the stirring bucket, and the end, extending out of the stirring bucket, of the piston rod is connected with a transmission mechanism. The bottom of the piston is connected with a flexible stirring belt. An air inlet one-way valve and a water outlet one-way valve are arranged on the side wall of thestirring bucket, an air outlet one-way valve and a water intlet one-way valve are arranged at the top of the stirring bucket, the water outlet one-way valve is communicated with the water draining pipe, and the water inlet one-way valve is communicated with the breeding pond. By adopting the giant salamander breeding pond, no direct impact is produced on fertilized ovum of giant salamanders, andthe oxygen content demand in water can be met.

Description

technical field [0001] The invention relates to the technical field of breeding equipment, in particular to a giant salamander breeding pond. Background technique [0002] Giant salamander, commonly known as giant salamander, is a second-class national wild animal protection and a rare aquatic animal unique to my country. It has biological advantages such as large size and fast growth, and the meat has strong nourishing properties and unique medicinal value, which has attracted people's attention. In recent years, giant salamander breeding under artificial breeding conditions has been successful. With the continuous expansion of the scale of artificial breeding of giant salamanders, giant salamander breeding has become a new industry with great economic and social benefits in aquaculture. However, due to the lack of scientific methods and improper management during the artificial incubation of fertilized eggs of giant salamanders, the artificial hatching rate is often low. ...

Problems solved by technology

However, due to the lack of scientific methods and improper management during the artificial incubation of fertilized eggs of giant salamanders, the artificial hatching rate is often low

[0003] Among the factors that affect the hatching rate, there are two more important factors. One is that the fertilized eggs of giant salamanders are in the early stage of hatching. The fertilized eggs need to be shaken, and the second is that the oxygen content in the water of the fertilized eggs must be kept above 5 mg / L during the hatching process. In order to meet these two conditions, the existing operation method is usually to set the water body in the breeding It is living water, which can not only shake the fertilized eggs during the flow of water, but also accelerate the dissolution of external oxygen into the water body

[0004] However, the above-mentioned conventional operation method also has the following problems. In order to meet the oxygen content in the water, the speed of water flow is usually relatively fast. Since the fertilized egg is very fragile, the fast flowing water will have an impact on the fertilized egg, and may The fertilized eggs will gather together and collide with each other, causing the fertilized eggs to rupture. If the speed of water flow is reduced, the dissolved oxygen will also decrease. Shock, can also meet the oxygen content in the water
