There are various ways to cultivate leeches, whether using mud ponds, mud pits or rivers and lakes, but in summary, there are only two ways: extensive cultivation in the wild and intensive cultivation. Which breeding method to choose should be based on the local actual situation and local conditions. If the conditions are poor, you can use local materials and adopt extensive farming in the wild; If the conditions are good, intensive intensive farming can be adopted, that is, a high-standard farming pond can be established to provide an ideal ecological environment for the growth and reproduction of leeches, and a higher yield per unit area can be obtained through industrial farming.
First, large-scale farming in the wild
Extensive farming in the field is a kind of farming method that uses natural conditions and protects them by delimiting the farming scope. Extensive farming in the wild does not mean that you don't care, but you should also put in enough provenances, properly put in bait, and finally catch it. Generally, there are reservoir culture, pond culture, swamp culture, lake culture, river culture, depression culture and rice field culture. These few
This method has the advantages of large culture area, abundant sunshine, rich natural bait, small investment and large income. However, the output per unit area is low and the management is difficult, so we should always pay attention to prevent natural enemies, escape and water level fluctuation. Two of them are briefly introduced below.
(1) swamp culture
Wetland is characterized by shallow water level, lush aquatic plants, rich organic matter and humus at the bottom of wetland, and rich plankton and aquatic animals. So as long as the fence is built, leeches can be released. It is necessary to observe regularly and supplement the bait appropriately. If the density is too high, salvage it in time. (2) Paddy field is characterized by shallow water level, suitable water temperature, sufficient rice shade, high oxygen content and rich bait, which is suitable for the growth and reproduction of leeches. Therefore, different kinds of leeches grow in most rice fields in China. Paddy field planting should choose plots with convenient irrigation and drainage, sufficient water, good soil and water conservation and fertility, and enclose them with fences. In the middle of paddy field, dig one or several ponds according to the size of the plot. Generally, it is advisable to dig a pond of 1 m2 in the middle of 100 m2. At the same time, protective communication ditches with a depth of about 30 cm and a width of about 30 cm are dug between ponds and around rice fields to make the ponds and ditches communicate. When drying fields, laying aside, fertilizing or spraying drugs, leeches should be lured into ponds or protected communication ditches with animal blood to prevent leeches from being killed. Fertilization should be changed to deep application of ball fertilizer, and spraying pesticides should be changed to low-toxic or non-toxic pesticides.
Hope to be adopted, thank you ~ ~
Question 2: What kind of feed should be fed to the cultured leeches? In order to celebrate the cultivation of wide-body golden leeches, mollusks such as snails can be raised. If bloodsucking leeches are bred, they can only be fed with animal blood.
Question 3: What do wild leeches mainly eat? Leeches generally like to suck fresh blood from animals. If it is artificially raised, it can be used: viscera of various animals, cooked egg yolk, compound feeding places, plant residues, freshwater snails, miscellaneous fish and earthworms. (Leeches can also feed pig blood)
Question 4: Who knows how to raise leech seedlings? What do seedlings eat? Thank you! 100, I recommend you to go to Baidu Library to read articles on leech breeding technology (leech seedlings), which are more talked about. You can try it and hope to adopt it.
Question 5: What feed blood do leeches eat?
Question 6: What do wild leeches eat? Wild leeches are commonly known as Japanese medical leeches in the field. They feed on the blood of people, livestock and frogs. Others feed on plant juices or small aquatic organisms.
1. Leech, commonly known as leech, grows and breeds in inland freshwater areas and is a traditional special medicinal aquatic animal in China. After processing, its dried product is used as Chinese medicine, which has the effects of treating apoplexy, hypertension, blood stasis, amenorrhea and traumatic injury.
Filmed from February 9th to 10. You can use loofah or tie a bundle of grass, soak it in animal blood, dry it and put it in water to trap it. After 2-3 days, you can take out the leeches, shake them off, pick out the big ones and remove the small ones, and repeat for many times to catch most adult leeches in the pond. After catching leeches, wash them, suffocate them with lime or white wine, or scald them with boiling water, dry them in the sun or dry them at low temperature.
3. Leech decoction has a strong anticoagulant effect and can significantly prolong the coagulation time of fibrin. Leech extract and hirudin have obvious inhibitory effects on platelet aggregation and thrombosis in rats, and have good therapeutic effects on disseminated intravascular coagulation.
4. Artificial leeches can feed snails, snails and mussels. As long as it is fed alive, the leeches such as Japanese medical leeches and Philippine leeches are fed with animal blood clots, and at the same time, it is necessary to cooperate with plankton culture in the base to achieve a reasonable diet for leeches.
Question 7: What do leeches like to eat? The scientific name "leech" is an omnivore. It mainly feeds on animal blood or body fluids, and often feeds on plankton, insects and mollusks in water. In artificial breeding, it is often raised with various animal viscera, cooked egg yolk, compound feed, plant residues, freshwater snails, miscellaneous fish and earthworms.
Question 8: Should I raise leeches in bottled water? What to feed it depends on what leech it is. Philippine cattle can feed coagulated blood clots without salt, and gold thread can feed screws.
Question 9: What leeches eat and how to raise leeches. Wuhan Zhengda Hi-Tech Agricultural Development Co., Ltd. is the governing unit of Hubei Special Breeding Technology Research Association, and Wuhan Industrial and Commercial Bureau has assessed it as the only designated breeding and seed supply unit for leech frogs, specializing in leech breeding, frog breeding and new variety breeding. The company has seven seed breeding bases. What leeches eat and how to raise leeches. A new leech and frog variety "Zheng Da No.9" and its high-yield cultivation techniques were cultivated. "Zheng Da No.9" leech and frog have stronger fecundity, faster growth, shorter breeding cycle, higher yield and stronger disease resistance. Strong adaptability, variety does not degenerate and other advantages, since it was put on the market, farmers have gained gratifying results, so it has attracted the attention and favor of farmers! "Zheng Da Brand" is trustworthy and the first choice for getting rich! Farmers are welcome to visit and study.
Question 10: Can leeches be raised, how to raise them and what to eat? Leeches, commonly known as leeches, belong to annelids. There are 400-500 species in the world, about 100 in China, and 89 species have been found. Most leeches live in fresh water, some are terrestrial and amphibious, a few live in salt water, and some are terrestrial and amphibious. There are species that feed on blood or body fluids, and there are also species that prey on small animals. People's common leeches in rice fields are called Japanese medical leeches, which feed on the blood of people, livestock and frogs. There are some grasshoppers living in the forests of Hainan Island and Taiwan Province Province. They often lurk in the grass and bushes. Leech can be used as a valuable Chinese herbal medicine after processing. In recent years, due to the threat of chemical fertilizers and pesticides to its living environment and predatory capture by human beings, the wild resources of leeches are decreasing day by day. In order to meet the market demand, the artificial breeding industry of leeches has developed rapidly.
