Pipeline circulation leech culture pond

Abstract

The invention discloses a pipeline circulation leech culture pond, and relates to the technical field of aquaculture. The pipeline circulation leech culture pond comprises a foundation, a square groove is formed in the upper wall surface of the foundation, the square groove is in a rectangular groove shape, and after a new water source is discharged into the culture pond through an opening, a second vertical pipe can open a drainage groove at the moment, and the water source in the culture pond is drained through a drainage pipe. After the second vertical pipe at the left side of the foundation is started, when the weather outside the culture pond is hot, the temperature of the water source inside the culture pond becomes higher under the irradiation of the sun, and therefore after warm water is drained to the outside through the drainage pipe, a water delivery pipe can discharge a low-temperature water source into the culture pond through the opening, so that after a high-temperaturewater source in the culture pond is replaced by the low-temperature water source, the temperature of the water source in the culture pond can be continuously kept low in high-temperature weather, andthe effects of reducing the occurrence rate of high-temperature leech diseases and improving the survival rate of leeches are achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pipeline circulation leech culture pond. Background technique [0002] Leeches, commonly known as leeches, belong to the phylum Annelida, class Hirudophylum, order Hirudognathus, and the family Hirudoceae. It grows and reproduces in inland fresh waters and is a traditional special medicinal aquatic animal in my country. Leeches contain hirudin, which can delay and hinder blood coagulation, thus having anticoagulant effect. Hirudin extracted from leeches has a very significant effect on dilating blood vessels, reducing blood viscosity and increasing blood circulation. It has been used in the treatment of stroke, high blood pressure, clearing blood stasis, amenorrhea, bruises and other drugs, as well as various health care products and cosmetics.

AI Technical Summary

Problems solved by technology

[0003] Leeches are called "soft gold". The existing technology mainly has the problem that the survival rate of leeches is low, and the rate from cocoon emergence to commercial products is less than 30%. July-August is the peak season for leech growth, but high temperatures often lead to long-term high water temperatures At 35°C, the leech will suffer from high temperature disease, which will cause the leech to get sick and die. For this reason, we have proposed a pipeline circulation leech breeding pond
