Problems solved by technology

Due to its extremely high medicinal value and economic value (the market price is 1,000 yuan per catty), it has caused artificial overfishing and damage to the ecological environment. In addition, the migration range of giant salamanders is narrow, and the reproduction rate and survival rate of seedlings are extremely low. leading to a decline in natural populations

Embodiment Construction

[0006] A constant temperature circulation type high-density cultivation method for giant salamanders is characterized in that:

[0007] (1), build 5 to 10 indoor cascade breeding ponds on slopes with a slope of 5 to 10 degrees, each cascade cultivation pond is provided with an overflow hole, and the water coming out of the overflow hole is injected into the cultivation pond of the next level, and finally The water from the overflow hole of the primary culture pond is poured into the water purification pond;

[0008] (2) The water in the water purification pool is filtered by biochemical cotton and activated carbon. The water quality is controlled: the ammonia nitrogen is below 0.025 mg / L, the transparency is above 62 cm, the nitrite is below 0.06 mg / L, and the dissolved oxygen is 5.8 mg / L. Above 1 liter, the hardness is stable at 2.8-33 mg / L;

[0009] (3) The pH value of the pH of the pool water is controlled between 6.0 and 6.9, and the temperature is kept between 19 and 22°...

Abstract

The invention relates to an artificial culturing method of a wild animal, in particular to a high-density culturing method of andrias davianus (giant salamanders). The high-density culturing method of the andrias davianus (giant salamanders) is characterized by comprising the following steps of: building 5-10 indoor stepped culture ponds on a sloping field with an angle of 5-10 degrees, wherein water used for circulating over flows is adopted in each culture pond; strictly filtering and purifying water quality, and keeping the temperature of the water at optimal growth temperature between 19 DEG C and 22 DEG C; and culturing the andrias davianus (giant salamanders) in a pond separation and classification way. The invention can provide optimal growth conditions for the culture of the andrias davianus (giant salamanders) and also save a large amount of energy, enhances the culture density and the survival rate, reduces the cost and increases the culture benefits.

Description

technical field [0001] The invention relates to a method for artificially breeding wild animals, in particular to a constant-temperature cycle-type high-density breeding method for giant salamanders. Background technique [0002] Giant salamander, commonly known as giant salamander, is a unique and rare amphibian in my country. It is mainly distributed in nine provinces and regions in the Yangtze River Basin in the central mountainous area of ​​China. Among them, Hunan, Hubei and Shaanxi provinces are the majority. Their living environment is mainly in the In mountain streams in deep mountain valleys at an altitude of 200-1000 meters. Giant salamander has high medicinal value. It has the effects of nourishing yin and kidney, nourishing blood and promoting qi, and has significant curative effects on anemia, cholera, dysentery, malaria, blood menstruation, etc., and can remove free radicals and excessive heavy metal ions in the human body , prevent heavy metal poisoning, delay...
