Due to the decreasing of wild leech resources in recent years and the medical value of leech, which has aroused widespread attention in the medical field, artificial breeding is imperative. Now for the biological characteristics of leeches, talk about the profits of leech breeding, marketing, technology, introduction and other key issues for reference. 1. Breeding profits. Some speculators claim that breeding every 667 meters ~ 2 (mu) leeches can produce 300 to 400 kg of dry goods, profit of 40,000 to 40,000
