Industrial giant salamander breeding pond

Abstract

The invention discloses an industrial giant salamander breeding pond, and belongs to the technical field of the giant salamander artificial breeding technology. The breeding pond comprises a pond body, a breeding net is arranged in the middle section of the pond body in the depth direction, a drainage ditch is formed in the bottom of the pond body, a cover plate capable of being opened and closed is arranged on the upper portion of the drainage ditch, and the drainage ditch is provided with a water outlet in the position of the pond body. The industrial giant salamander breeding pond is reasonable in structure and can discharge waste water with high impurity concentration selectively, so that stress, caused by frequent water changing, of giant salamanders is effectively reduced; water in the pond body is divided into two layers of spaces, breeding and impurity collection and purification are conducted relatively independently, and therefore influences on the giant salamanders of impurities in breeding is reduced to the maximum limit; active adsorption materials also enable harmful substances (such as ammonia nitrogen) in discharged water to be eliminated, high-density and large-scale breeding of the giant salamanders are greatly promoted while the breeding survival rate and the growth efficiency are guaranteed, and water consumed by breeding and occupied land are greatly reduced; the industrial giant salamander breeding pond has good social and economic benefits.

Description

technical field [0001] The invention relates to a culture pond, in particular to a giant salamander factory culture pond, and belongs to the technical field of giant salamander artificial breeding. Background technique [0002] Giant salamanders (salamanders) are now facing a huge crisis. Wild salamanders only exist in Shaanxi, Hunan, and Sichuan where the natural environment has not been destroyed; and now the average annual breeding volume of artificially bred salamanders in the country is 100,000. Giant salamander is an animal with high edible value. Its meat is tender, delicious, high-quality protein, rich in amino acids and trace elements, and has high nutritional value. It is known as "ginseng in water". [0003] The existing artificial breeding of giant salamanders has a low survival rate, and ordinary breeding ponds are mainly used for breeding. In order to ensure the survival rate of the breeding, the water in the breeding pond needs to be replaced frequently, but t...

Problems solved by technology

[0004] The purpose of the present invention is to: aim at the problems mentioned above, to provide a giant salamander industrial culture pond, which can solve the problems of existing giant salamander culture ponds, and can effectively reduce the water exchange rate while ensuring the quality of the water body. Reduce the stress caused by changing water, ensure the survival rate and growth efficiency of breeding, and at the same time effectively increase the breeding density and scale
