Leech (leech) will become a new breeding hot spot after crayfish.

The price of leeches has been singing all the way in 2011, and the purchase price of fresh leeches has reached 60,70 yuan per catty. In recent years, due to the annual decrease of wild resources of leeches and the medicinal value of leeches, the market supply and demand of leeches has become tense. In recent years, many people have begun to develop the leech breeding industry, and a number of pioneers of leech breeding have appeared in Zhejiang, Anhui and other places. At present, under the depressed market situation of traditional breeding varieties, many farmers have also set their sights on this relatively new leech farming project. recently, China's aquaculture network has also set up special information services for leech farming according to the needs of the aquaculture market, providing the majority of farmers with an information service and exchange platform for understanding and learning leech farming.
