Artificial ecological circulating pool for giant salamanders

Abstract

The invention discloses an artificial ecological circulating pool for giant salamanders. The artificial ecological circulating pool comprises a young giant salamander pond, an adult giant salamander pond, a fish pond and a purifying pond which are sequentially communicated in a circular sequence, wherein a sloping surface descending from up to down is arranged on the bottom surface of the young giant salamander pond and the bottom surface of the adult giant salamander pond; the purifying pond is provided with a water pump device, and a water outlet of the water pump device is positioned in the upper end of the sloping surface of the young giant salamander pond. The artificial ecological circulating pond disclosed by the invention adopts closed-loop design, and through the continuous sloping surface of the young giant salamander pond and the adult giant salamander pond and the water pump device, the ecological design of the circulating pond is realized. The circulating pond is in favor of food looking and movements of the giant salamanders, the fish farming pond can be used for feeding the giant salamanders, the purifying pond can be used for feeding microbial populations so as to purify water, and facts prove that after the microbial population is fed so as to purify the water and reduce the concentration of nitrite, the growth of the giant salamanders and feed fishes is significantly facilitated.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an artificial ecological circulation pond for giant salamanders. Background technique [0002] Giant salamander commonly known as salamander (Andrias davidianus ), belonging to Amphibians, Cauraceae, Cryptobranchidae, is the largest and most precious amphibian in the world. The earliest amphibians appeared in the late Devonian, and giant salamanders are a group that transitioned from aquatic to terrestrial. It not only has some primitive characteristics of fish, but also has a body structure that is initially English. The giant salamander's skin is exposed, and it still cannot solve the problem of living on land to prevent the evaporation of water in the body. Therefore, in order to get rid of the shackles of "water", it can only live in humid areas near water. Therefore, giant salamanders cannot completely leave the water, and egg laying, in vitro fertilization, and hatching all nee...

However, this breeding condition hinders the development of giant salamanders

However, traditional artificial breeding ponds tightly circulate water to form "streams", which have been proved to be harmful to the growth of giant salamanders.

The waste excreted by giant salamander and feed in circulating water contains more NO 2 -N, when the content is too high, it will adversely affect the development of the parental gonads, and in severe cases, it will cause liver poisoning and death of giant salamanders. The traditional method is to change water frequently, but the production cost is too high for producers
