Abstract

The utility model discloses a simulated ecological breeding pond for giant salamanders, which comprises a large pond and giant salamander caves which are spaced in the large pond. The large pond is rectangular. An artificial stream is arranged in the middle of the large pond. The spaced giant salamander caves are arranged on the two sides of the artificial stream. Waterproof films and coarse sand layers with thickness being ranged from 10cm to 12cm are laid at the bottoms of the large pond and the giant salamander caves. The tops of the giant salamander caves are sequentially covered by sandy soil with thickness being ranged from 30cm to 40cm. A ventilation and observation hole is arranged at the top of each giant salamander cave. The entrance of each giant salamander cave is communicated with the stream. Slow-flow water filling ports which are communicated to the caves are installed at the upper parts of rear walls. The spacing walls of adjacent giant salamander caves are isolated by coarse sand with thickness being ranged from 10cm to 20cm. The simulated ecological breeding pond for the giant salamanders can prevent external sewage from seeping into the breeding pond, the water in the pond can be kept clear and the content of dissolved oxygen in the giant salamander caves is above 6mg/l. Five to ten couples of breeding giant salamanders can be fed in the simulated ecological breeding pond, the needs for breeding and pairing the giant salamanders can be fully met and the breeding rate of the giant salamanders can be improved by 20 percent to 30 percent.

Description

The bionical attitude breeding of giant salamander pond

Technical field

The utility model relates to a kind of giant salamander breeding pond, the bionical attitude breeding of particularly a kind of giant salamander pond.

Background technology

Giant salamander, the popular name giant salamander, amphibian animal, endangered at present, belong to national two classes and watch for animals.The successful giant salamander artificial propagation techniques of the nineties research and development in last century has been alleviated the in short supply of wild resource to a certain extent, but because this specification requirement difficulty is big, its reproduction rate only is 1: 15-20.The bionical attitude breeding of the giant salamander of rising in mountain area, China Qinling Mountains in recent years has tremendous development, and the reproduction rate of giant salamander has been brought up to 1: 100-110.But in the technology of the bionical attitude breeding of whole giant salamander, also there are many deficiencies mutually in the bionical attitude technology in giant salamander breeding pond, and show following several aspect: 1, the salamander cave is too sealed, the dissolved oxygen in water deficiency, generally only below 5mg/L, can not satisfy the respiratory demand of giant salamander; 2, the giant salamander ight soil in the salamander cave, cast off a skin and refuse such as dead algae is difficult for discharging, grow germ easily, produce materials such as ammonia nitrogen, hydrogen sulphide, very big to giant salamander harm; 3, temperature drift in the cave in summer is unfavorable for the growth of giant salamander, and diseases induced easily; 4, Da Chi and salamander cave do not isolate substantially, and the mutual channelling of the water in pond, cave is unfavorable for the control of disease.Above-mentioned deficiency has influenced the further raising of reproduction rate of giant salamanders greatly.

Summary of the invention

The purpose of this utility model is to overcome the existing deficiency in existing giant salamander bionical attitude breeding pond, proposes a kind of bionical attitude breeding pond that is more conducive to the giant salamander breeding, grows up.

The technical scheme that realizes above-mentioned purpose is: the bionical attitude breeding of a kind of giant salamander pond, comprise Da Chi and the salamander cave at a plurality of intervals in Da Chi, it is characterized in that: described Da Chi is the rectangle of long 7m-14m, wide 6m-7m, the interposition of Da Chi is equipped with an artificial streams, and salamander cave, described interval is arranged on the both sides in artificial streams; The bottom in described Da Chi and salamander cave is equipped with waterproofing membrane, be equipped with the thick coarse sands layer of 10-12cm on the film, top, salamander cave is coated with cover plate and the thick sandy soil of 30-40cm successively, can plant the land-based activity place of grass on the sandy soil as giant salamander, a ventilative peep hole is arranged at the top in salamander cave, the hole in each salamander cave communicates towards artificial streams and with the streams, the back wall upper position in each salamander cave is equipped with in each cave and forms the water filling port of unhurried current, has the rough sand of 10-20cm to cut off between the division wall in adjacent salamander cave.

A kind of preferred version as above-mentioned technology: the drop in described artificial streams is 30cm, depth of water 20-30cm, and flow velocity 0.2-0.3m/s, there is filter at the following mouth of a river.

Another preferred version as above-mentioned technology: high enclosure wall of about 1m or purse seine are set around the described Da Chi, are used to prevent that giant salamander from fleeing from breeds the pond.

Advantage of the present utility model is: 1, the waterproofing membrane of bottom can prevent to leak and the infiltration of outside sewage, keeps pool inner water matter stable; 2, the natural living environment of the similar giant salamander of the formed singing of the stream in the streams in the pond helps giant salamander breeding and growth; 3, be provided with the miniflow water system in the salamander cave, promoted water circulation, can be in time the casting off a skin of giant salamander, ight soil, dead algae and foreign material be discharged, keep in the cave water quality pure and fresh, feel nice and cool, dissolved oxygen reaches more than the 6mg/l; 4, the sandy soil at top, salamander cave and cover grass can be in summer to salamander cave cooling heatstroke prevention, but winter heat-preserving anti-freezing, keep the good living environment of giant salamander.This bionical attitude breeding pond can be put 5-10 in a suitable place to breed to kind of a salamander, satisfies giant salamander breeding pairing demand fully, can improve reproduction rate of giant salamanders 20-30%.
