According to the latest Chinese medicinal materials market news, on April 1, 2010, the sales price of leeches in Bozhou Pharmaceutical Market has reached 450 yuan/kg, while the price in mid-2009 was still between 240 and 260. , so the prospect of leech breeding is promising. However, the First Step Network of Entrepreneurship reminds: According to Chinese medicinal materials market news: At the beginning of 2009, there were no domestic leeches on the market in Bozhou Pharmaceutical Market, because domestic leeches are still in an experimental state. If someone advertises that leech farming is very easy, they may sell them at a high price. Kind of liar. Market Prospects for Breeding Leeches
As leeches are a valuable medicinal resource and have a variety of medicinal functions in medicine, they are an animal-based traditional Chinese medicine with great development value. With the aging of the population and the increase in cardiovascular and cerebrovascular patients (the incidence of hypertension and heart disease accounts for 2-5% of the population), coupled with people's preference for traditional Chinese medicine products, the demand for leeches will further increase. According to the "China Livestock and Fisheries News" report on December 6, 1998, the total demand for dried leeches at home and abroad in 1997 reached more than 250 tons, but the actual supply was only 150 tons, leaving a gap of 100 tons. According to statistics from relevant experts, the leech shortage will reach 300,000 kilograms by the end of 1999. Due to the growing contradiction between supply and demand, prices have continued to rise. The selling price of pure parallel imports has risen from about 80 yuan per kilogram last autumn to about 150 yuan per kilogram currently. The increase has increased by 87.5%. Things aren't going to get better anytime soon. The reasons for the rise in leech prices come from several aspects. On the one hand, some pharmaceutical factories in the mainland and Hong Kong have a large demand for leeches; on the other hand, the European and American consumer markets are huge. In recent years, Japan, South Korea, and Southeast Asian countries have also A large number of leeches are imported from my country, causing the domestic demand for leeches to increase exponentially; third, due to the environmental pollution caused by the extensive use of pesticides, chemical fertilizers and chemical industry emissions in recent years, wild leech resources have declined sharply; fourth, due to the increase in artificially cultivated leeches, China has just started, and there are not many large-scale leech farms.
Our country has been successfully raising leeches artificially since 1995. Although the current development scale is not large, the benefits are very considerable. The net profit per mu is more than 20,000 yuan, which is 7% of the current benefits of fish farming. -10 times. Due to the promising market prospects and considerable benefits of artificially raising leeches, some people of insight have begun to organize large-scale artificial breeding to seize the market.
(4) Artificial breeding of leeches is simple and easy
Leechies have strong adaptability, strong hunger tolerance, and strong disease resistance, so artificial breeding of leeches is not affected by regional conditions. According to the restrictions, it can be raised in ponds, pits, tanks, barrels, etc. The feed is made of plankton in the water, small insects, field snails, river mussels, animal blood clots, earthworms, humus on the soil, etc., and can be fed once a week. The general stocking density is: 10,000 young leeches per cubic meter of water surface; 5,000 adult leeches per cubic meter; about 500 seed leeches per cubic meter. For pit pond and ditch culture, it is appropriate to stock 2,000 seed leeches per acre of water surface. Family farming can be carried out according to the pit and pond farming method, using bricks to build a pond with a height of 70-80cm, a length of 200cm, and a width of 120cm. The bottom of the pond is paved with bricks, 15-20cm of soil is spread, the walls are cemented, and some stones are placed in the pond. , aquatic plants, branches, etc., and a feeding platform should be set up. The feeding platform should be 3-5cm lower than the water surface. Drainage holes should be left at the bottom of the pool. The water depth in the pool is about 30cm. There is a shed on the top of the pool (protected from rain and sun). Each pool is stocked with 200 leeches. When the young leeches grow to about 2cm, they can be cultured in separate pools. Therefore, artificial breeding of leeches has the characteristics of requiring no labor, extensive and simple feeding and management, low feed cost, high reproduction rate, silent, odorless and pollution-free, low investment, and quick results.
Benefit Analysis of Artificial Breeding Leeches
Leeches are hermaphroditic and cross-fertilized. Each species of leech can reproduce and can reproduce 2-3 times a year. If conditions permit, temperature-controlled breeding can be carried out to control the water temperature at 20-28°C, which is conducive to the rapid growth of leeches and can break the hibernation habit. The reproduction volume is significantly increased, and the maximum number of eggs can be laid up to 5 times.
If each seed leech reproduces 2-3 times a year and lays an average of 8 egg cocoons per year, each cocoon can hatch an average of 40 young leeches, and the average survival rate is 90, then each seed leech can reproduce per year: 1×8×40×90=288 leeches, and there are about 80-100 leeches per kilogram. Then each kilogram of leeches can reproduce per year: 288×100=28,800 leeches. The young leeches produced can grow into commercial leeches in 6 months. There are about 100 fresh leeches per kilogram, and the recovery rate of fresh leeches is 14.3; that is, 7 kilograms of fresh leeches can be dried to obtain 1 kilogram of dried products, and the dried products obtained by breeding per kilogram of leeches per year are: 28,800 ÷ 100 leeches. ÷ 7 kg = 41 kg, sold at a dry price of 120 yuan per kilogram, then the annual gross profit from raising one kilogram of leech is: 41 kg × 120 yuan/kg = 4920 yuan, minus the investment and breeding costs, you can Net profit is about 4,000 yuan. If a farmer raises 10 kilograms of leech species, he can earn a net profit of 30,000 to 40,000 yuan per year. With a one-time investment and repeated reproduction, he will benefit year after year. Therefore, artificial breeding of leeches is the first choice for rural and urban residents and laid-off workers to get rich.
