Artificial breeding of leeches: successful breeding of leeches in Taihu Leech breeding Center, Wujiang City, Jiangsu Province in 2001

This is the news material about leech breeding in 2001, which can be used as a reference for friends who are interested in artificial breeding of leeches.

After four years of technical research, the technology of artificial breeding and breeding of leeches has been successful in Tuncun Town, Wujiang City, Jiangsu Province, which has become the only area in the country dedicated to leech breeding.

Leech has high medicinal value, which is mainly used in the development of drugs for the treatment of cerebral thrombosis, hypertension, stroke and so on. According to reports, due to water pollution and other factors, the number of wild leeches in China has decreased sharply, with an annual output of less than 200 tons of dried leeches and an annual gap of more than 300 tons. Artificial breeding is the fundamental way to solve the serious shortage of leech resources. In 1997, Tuncun Town cooperated with Nanjing Agricultural University to carry out artificial breeding of leeches, and the first generation of leech seedlings were cultivated last year. After more than a year of trial breeding, we have recently explored a whole set of techniques from seedling breeding to adult leech breeding. 3 million seedlings are planned to be bred this year, and seedlings are expected to emerge one after another around May 20. Through the release of information on the Internet, more than 400,000 seedlings have been ordered across the country.

Tuncun Town Multi-Service Company has cooperated with the traditional Chinese Medicine Research Department of Nanjing Agricultural University to set up the Taihu Leech breeding Center in Wujiang City. since March this year, two training courses have been held. Nearly 100 people from Anhui, Zhejiang and parts of Jiangsu Province have received training in aquaculture techniques. According to the results of trial cultivation, 20, 000 to 15000 seedlings can be stocked per mu of rice field, which can be sold in about a year and a half. after deducting the cost, the income per mu is expected to be about 2500 yuan.
