Recirculating aquaculture system of leeches

 DOWNLOAD

    The leech is a kind of mollusc aquatic animal. Also known as leeches. It's a very adaptable animal. The medicinal value is very high. Live leeches are used in medicine to treat some special diseases. The body contains hirudin and other substances that can dissolve thrombus, which has a unique curative effect in the treatment of three high. Therefore, leeches have always been a valuable Chinese medicine. The high profit of breeding leeches is caused by the short supply of market business.

    Breeding of leeches is relatively simple. It can breathe through its skin. So you don't have a high requirement for dissolved oxygen. Feeding with spiral lions. Leeches have a strong ability to adapt to the environment and can survive high temperature, low temperature and low oxygen environment. But if you want to increase production, you need to manage water quality carefully. Among them, the circulating aquaculture of leeches is one of the most impressive cultivation modes.


    Recirculating aquaculture is a new aquaculture model based on recirculating aquaculture system. Generally speaking, leeches can survive in wild water environments. But recirculating aquaculture is the water index of artificial intervention treatment. Minimize the amount of organic matter in the water. Dissolved oxygen as high as possible. Ammonia nitrogen, nitrite and other harmful substances as low as possible. Meanwhile, particulate matter such as organic matter in water is a food source for some bacteria and viruses. Therefore, after feeding the leeches, the processing capacity of the circulating aquaculture system       should be increased. Make water quality standard circulation. Do not discharge aquaculture wastewater to the outside world.

    Leeches are most afraid of the rapid breeding of pathogenic bacteria in the water in high temperature weather. Causing the leeches to get sick. Therefore, in addition to filtration, it is necessary to carry out certain disinfection treatment on the water body. Common sterilization and disinfection equipment have ozone generator, overflow ultraviolet sterilization device and other equipment. But their premise is still that the water has to be pretreated by previous circulating aquaculture systems.


    In the expansion plan, the greenhouses can be used to breed the leeches, and even make the leeches winter. If the technology is strong, it can be combined with some aquatic plants for imitation of ecological culture. Aquatic plants can not only provide leeches with attachments adapted to their living habits, but also purify water.
    In recent years, many people cultivate leeches in canvas ponds. But most people fail. The main reason is that there is no water treatment system, a pool of stagnant water is certainly not. Running water culture, easy to bring in harmful bacteria and viruses from the water outside. And changes in the weather can make leeches stressed. Some people use the idea of cultivating algae and bacteria in the outer pond to raise leeches, and have also achieved success. But not everyone is so sure. Using systems to repeatedly treat water is not only an environmentally friendly way of farming, but also a low-risk investment. In common breeding water bodies, the breeding density of leeches is very small, but if the method is proper, the breeding density can be greatly increased. The overall farming benefits are considerable.

    Aquatic industry has a strange phenomenon, is will raise as will sell. The same is true of leech farming. If it is only processed with salt and sold as medicinal materials, the profit is only average. However, if the breed is a wide-body golden leech, it can be sold live to some specialized units through certain channels. Monomer sales price is much higher than the general medicine.
