CATDOLL : CATDOLL: What are the leech breeding techniques?

Some people have seen the frequent broadcast of TV. Some people have seen the doubled increase in the price of medicinal materials in the market. But how many people know how muddy the water of artificial breeding is. How many people are mixed in it and want to fish in troubled waters》"|》||".'――

1: Novice level Many people who run Hengnapeng start with a trial mentality. They want to use a small investment to exchange for a big return. So they believe the TV and advertisements that a hundred-mesh net around the pond is a breeding farm. After putting the seed leeches sent back from thousands of miles away into the pond, they feed them with soy milk, clams, and blood according to the instructions. At the same time, they start to calculate how many cocoons each leech will produce and how many seedlings each cocoon will produce. How much can they earn by the end of the year after deducting the minimum survival rate? But before they wake up from their beautiful dreams, they find that there are fewer and fewer leeches in the pond. By the end of the year, they have not caught many leeches per acre. Could it be that they were eaten by natural enemies? They quickly drained the water and found that there were not only a lot of fish in the pond, but also a lot of species. Why are there so many fish in the pond? But they have clearly cleaned the pond at the beginning. This is puzzling. >> Let me tell you a joke. A friend of mine once caught a few kilograms of big fish in it. —— ... . , tens of thousands of dollars are gone

2; Entry level So some people thought, don’t you have many natural enemies? I can’t afford to offend you, but I can’t avoid you. So they didn’t look at what others did and just built their own way. One after another, cement pools like swimming pools rose from the ground, some of which were 1.6 meters high. They thought, this is it. Let’s see what your natural enemies will do. Well, this trick is unique. When the seedlings emerge, the water is densely packed. It’s so beautiful to see it! ! ! ! --- But the joy has not passed. I found that the seedlings are getting fewer and fewer. Even the seed leeches die a lot every day. What’s more important is that the small leeches are like immortals and have no interest in the soy milk and blood you prepare for them. I touched two river clams, but there was not a single wide-bodied leech in them. In the end, they all starved to death. They grew very little. At the end of the year, I looked at it. . . The harvest was even less than the investment. And when cleaning the pond, there were lobsters, eels, loaches and fish. ---Dizzy------Just like that, tens of thousands of dollars were lost. 》“》?%……―%

3: Hardcore people. At this stage, most people have learned why leeches are expensive, but they are forced to find other ways out due to various reasons such as money and family. This is natural selection. The few people left began to deny their previous understanding. They rebuilt the pond according to the habits of leeches and their own convenience to accommodate their egg-laying and hatching. Seedling needs? Only now do they know that the food mentioned in the manual/online/professors is fake. Died during the winter? Died during egg-laying? And the real food is snails. Except for the supplementary materials when the seedlings are just born, the rest of them feed on snails. Seeing this, many people will say, "Isn't it just snails?" There are many snails in my hometown. It's easier said than done. You will know when you carry a large sack to the river to look for them yourself! ! ! The seedlings eat snails as big as soybeans. It depends on how many you can find in a day. Ordinary snails are now 7.8 yuan per pound, and sometimes you can't buy them even if you have money. Moreover, the seedlings only eat snails with similar bodies to theirs. They dare not touch big things, let alone eat them. Occasionally, a brave head just pokes halfway in and is caught by the big snail when it closes its lid. Where can you find a suitable snail? Therefore, they set their sights on the best food. The golden apple snail is large in size. It has a variety of diets, lays many eggs, and reproduces quickly. It is true that food and grass must be prepared before troops move. When the seeds are introduced, they are introduced together. Experiment-+||? ・#￥・%￥%%……￥. Explore/,. '/“';';Reproduction-+――――#￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥

Conclusion: In fact, the current technical bottleneck of leeches is seedling cultivation and protection from natural enemies. If you want to avoid risks and not repeat the same mistakes, you can directly raise young leeches for fattening instead of breeding seedlings. Try your best, my friend. [Readers of this article have found that this is a portrayal of your experience. ++---Let's make a beautiful triple jump, my friend. Skip the detours I took, and you will have the last laugh like me---

Leech breeding method 1. Site: First, select a site, transform it into a breeding pond, and install an isolation net around it.

2. Density: The breeding density of leeches should not be too high, and a maximum of more than 80,000 leeches should be released.

3. Feeding: Leeches are omnivorous animals and can be fed with snails, shells, pig blood, etc.

4. Environment: Leeches like warm environment. The suitable growth temperature is between 15 and 30 degrees Celsius. The surrounding temperature needs to be controlled at ordinary times.

Leech breeding precautions

Water quality: Water sources can be divided into surface water sources and groundwater sources. Regardless of which water source is used, it should generally be selected in an area with abundant water, good water quality, and an unpolluted surrounding environment.

Air: Harmful substances in the air will not have a direct impact on the water quality of the pond, but they will have an indirect impact. For example, toxic substances in toxic air will dissolve in the water through air flow. Although it will not cause the death of leeches, it will affect the quality of leeches. Some will also have a direct impact on the water quality of the water body. For example, sulfur dioxide dissolved in water will reduce the pH value of the water, causing an impact on leeches.

Natural enemies: The natural enemies of leeches are mainly voles, frogs, weasels, snakes, etc. They can be controlled by using electric nets and tools to trap them. Leech management technology

1. Selection of leeches

When choosing leeches, you must select fat and large ones. Generally, the weight of each leech should be above 12 grams. They should also be active, have a smooth surface, bright colors, and no scars on their bodies. The general stocking density of leeches is about 20-25 kilograms per mu, about 2,000-2,500 leeches.

2. Incubation

Leeches usually lay eggs at temperatures above 11 degrees Celsius, and hatch into baby leeches after 16 to 25 days. Three days after hatching, baby leeches can find food on their own and suck the blood of snails. Put 20 kg of snails or other food in every 1,000 leeches, and generally feed the leeches with blood clots of poultry and livestock once a week. It is important to clean up the remaining food in the water at any time to keep the water clean.

3. Bait

The broad-bodied golden leech usually feeds on the blood of animals, and also sucks plankton, small insects, juvenile mollusks, and humus on the mud surface. However, from mid-April to late May each year, it is the early growth period of young leeches. At this time, the blood of vertebrates such as pigs, cattle, and sheep can be sprinkled on the water surface for young leeches to suck. However, the amount of blood to be released should be determined according to the density of young leeches. It should be released in small amounts and multiple times to prevent excessive feeding and adverse effects. In late May, live snails, earthworms and other mollusks can be released into the pool for leeches to suck. The amount released should not be too much, and the insufficient part can be supplemented with artificial bait.

Leech farming, in addition to some breeding sites, equipment, water sources, etc., is also very important for seedlings and the management of leech disease prevention and control (i.e., breeding technology) during the breeding process. Leech farming is prone to various diseases, such as enteritis, stress, edema, bubble disease, etc. If they are not treated in time and effectively, they will lead to a large number of leech deaths. Therefore, daily management is very important during the breeding process.
