**Leech Cultivation Technology: Whitmania Pigra (also known as the "grasshopper leech") is an annelid commonly referred to as a medicinal leech. It belongs to the category of medical organisms and has been used for centuries in traditional Chinese medicine. One of its most valuable components is hirudin, a natural anticoagulant that helps prevent blood clotting. In ancient times, Li Shizhen, the famous physician from the Ming Dynasty, documented its use in treating conditions such as blood stasis, menstrual disorders, bruises, and even rickets. Today, it’s also being explored for applications in cancer treatment and limb reattachment.**
**Artificial breeding of leeches offers a promising opportunity for rural farmers. These creatures are highly adaptable, can survive long periods without food, and are resistant to many diseases. They can be raised in various environments, including cement ponds, rice paddies, or even small containers. Their diet includes plankton, small insects, snails, river lice, animal blood clots, earthworms, and organic matter. Feeding them once a week is sufficient, making this a low-cost and easy-to-manage project.**
**Leeches thrive in water temperatures between 15°C and 30°C. Below 10°C, they stop feeding, and above 35°C, their growth is affected. They are hermaphrodites, reproducing through cross-fertilization. Spawning typically occurs from mid-April to May, with 3–5 eggs laid at a time. After 15–25 days, each batch can produce up to 40 offspring. With 667 square meters of aquaculture space, planting 50–60 kg of leeches can yield over 30,000 yuan annually. After deducting costs, net profit can reach around 20,000 yuan.**
**Due to the decline in wild populations caused by environmental pollution and over-harvesting, there is a growing demand for farmed leeches both domestically and internationally. Breeding leeches is a low-risk, high-return business. It requires minimal investment, uses idle land efficiently, and provides stable income. The market price for dried leeches ranges from 150 to 200 yuan per kilogram.**
**Our company offers high-quality "China No. 1" leech seedlings at 480 yuan per group, along with a comprehensive aquaculture CD that includes breeding techniques. A single technology CD is available for 50 yuan. We also provide long-term buyback services for dried leeches. This is a great opportunity to start a profitable and sustainable business.**
