Hirudo nipponia net cage breeding method and special net cage thereof

Abstract

The invention provides a Hirudo nipponia net cage breeding method and a special net cage thereof. The escape prevention and feeding functions of Hirudo nipponia are integrated, and the Hirudo nipponia net cage breeding method and the special net cage of the Hirudo nipponia net cage breeding method can adapt to pond breeding, cement pit breeding, breeding in a laboratory and various conditions. According to the special net cage for the Hirudo nipponia net cage breeding, the net cage is of a closed structure of a hollow-structure cuboid or cube, a metal or plastic framework is arranged on the inner side of the net cage, polyethylene or polypropylene meshes adhere to the framework, and the whole special net cage mechanism is supported by the framework and is stable. The problems that Hirudo nipponia feeding is difficult, aquaculture water can be easily polluted, the death rate of the Hirudo nipponia is high, the Hirudo nipponia can be easily invaded by natural enemies, and escape prevention is difficult are solved, and conditions are created for large-scale breeding of the Hirudo nipponia.

Description

technical field [0001] The patent of the present invention relates to related equipment in the field of Japanese medical leech breeding technology, in particular to a Japanese medical leech breeding net cage and a feeding device. technical background [0002] Japanese medical leech is the only blood-sucking leech species recorded in the "Chinese Pharmacopoeia". Due to the unique curative effect of Japanese medical leeches in promoting blood circulation, promoting menstruation, and anti-cancer, the supply of Japanese medical leeches is in short supply. The extensive use of chemical fertilizers and pesticides has depleted wild Japanese leech resources. [0003] The artificial breeding technology of Japanese medical leech is very difficult, and has not yet formed a large scale. The specific problems mainly focus on the following aspects: 1) The water body is easily polluted and deteriorated, and Japanese medical leech is easily infected with diseases and dies. When feeding, t...

AI Technical Summary

Problems solved by technology

Feeding blood clots, there are too few feedings, the leeches cannot be full, so that the growth rate is slow, too much feeding, the blood clots are not easy to clean up, causing water pollution, leeches are easy to infect diseases, etc.

In addition, when the water area is too large, it is difficult for blood-sucking leeches to find the target in a short time, resulting in prolonged feeding time and easy corruption of water quality; It absorbs the body of the operator, absorbs blood, and is difficult to clean up, which brings great inconvenience to the breeder; 3) Japanese medical leeches are small in size and have strong mobility, and escape during breeding is very common and extremely difficult to control; 4) Japanese leeches are vulnerable to the invasion and feeding of dragonfly larvae, lobsters, fish and other organisms, which has also brought a certain degree of impact on the large-scale breeding of Japanese leeches
