What should we pay attention to in leech farming? What is the real yield? Is the investment big? 10

I think we must pay attention to some air, and there must be fresh water sources, if it is polluted, it is not okay, the yield is not too large, and its investment is not large, because it can be reproduced, so its cost is not high.

The first point to pay attention to is that this environment is very important, do not ignore the second point, that is, the whole process of breeding will happen some things, the third point is easy to get what kind of disease, we must pay attention to the real yield in time, in fact, in a pound of leeches will probably produce three catties, then the amount of investment is not very large.

Farming mode with net cages. Hang ten cages, a cage produces about 40 catties of leeches, and the output value per mu is about 10,000. Pay attention to the water level in the cage above 80 cm in summer, and in hot weather, once you find that the leech's appetite decreases and the body is blackened, you should always pay attention to the occurrence of dryness.

Leeches grow and reproduce in inland freshwater waters, and are traditional Chinese special medicinal aquatic animals, and their dried products are soaked in traditional Chinese medicine. Therefore, the development of leech aquaculture has good market prospects and economic benefits.

The profit of farming leeches depends on how you breed and how long you breed them. If your seedlings are propagated by themselves and all kinds of equipment are available, such profits are very considerable, and the cost is only snails and daily utility bills. If you are a novice, the seedlings have to introduce all their own equipment, then the profit will be relatively low.

Terrain:

The choice of terrain should be leeward and sunny, and the environment should be excellent. In this way, the light time can be increased in spring and autumn, the growth period of leeches can be prolonged, and the winter can be windproof and cold-resistant, so that leeches can safely overwinter. At the same time, the beautiful environment can not only prevent heatstroke in summer, but also increase the number of live animals and plants, and provide sufficient bait for leeches.

China's freshwater waters are vast, and there are obvious differences in water quality due to regional differences. The physical and chemical indexes that determine the quality of water quality mainly include temperature, salinity, oxygen content, pH value, water color and fertility.

Consider whether the water source is contaminated to the site. Seriously polluted waters, such as abnormal water color, increased turbidity, increased suspended solids, increased toxic substances, and foul odors, should never be used. At the same time, it is also necessary to consider the changes in the water level of the water area within one year or even several years, so as to ensure that there is water in times of drought and not flooding in times of flooding.

1. Breed problem.

Although there are many varieties of leeches, but the varieties of leeches that can be cultivated artificially are the golden leeches, which are the general names of the wide-body golden leeches, the glossy golden leeches and the sharp and thin golden leeches, and the most suitable for artificial breeding is only the wide-bodied golden leeches, and the benefits of other varieties are not too good, so they should be identified when introducing seeds.

2. The benefits of introduction.

Due to the climb, leeches have become a low-cost and efficient breeding project, but not all the benefits are very good. It is common to see that some units and individuals who sell seedlings use seedlings with poor breeding efficiency to pass off as high-quality or purified seeds, resulting in heavy losses for farmers.

3. The specification of the introduction.

Leeches have to grow for more than 2 years before they have the ability to reproduce. When the body weight is less than 15g, it will not be introduced, and it will not be introduced after June, so as not to introduce leeches or young leeches that have been ovulated, resulting in no benefit in the current year.

Generally speaking, leech farming will choose pond culture, which requires farmers to lease land, excavate bases, build anti-escape nets and so on. Taking 5 acres of breeding area as an example, the funds for leasing land are about 5,000 yuan, the excavation base needs about 4,000 yuan, and the anti-escape net needs about 3,000 yuan, and this part of the investment is about 10,000 yuan. In addition to this cost, farmers also need to breed bait, and the purchase cost of raw materials is about 3,000 yuan.

In addition, the important thing in leech farming is to grow leeches, and the cost of 250 kilograms is about 80,000 yuan. In addition, the management fee of 10,000 yuan, the disinfection fee of 200 yuan and a small amount of water and electricity bills, the initial investment is about 100,000 yuan.

It mainly depends on whether the environment is suitable and the sales of finished products after breeding.

Attention should be paid to the use of feed, as leeches are more demanding in their food needs, so attention needs to be taken. Pay attention to the water temperature, as it will directly affect the growth and development of leeches.

First, do a good job of knowledge reserve before breeding, which can solve some common problems; second, play the role of fertilizer and cultivate good water quality; Third, reasonable feeding and improve the use rate of feed.

Be careful not to let leeches get sick, because the infection is particularly strong, and the water should be changed in time, which is also conducive to growth.

Pay attention to the rationality of breeding density, it is best to plant some duckweed aquatic plants in the breeding site, which can play a role in purifying water quality, and at the same time pay attention to changing the water from time to time to maintain the transparency of the site water.

First of all, we should protect ourselves when we come into contact with leeches, because this animal is very harmful to us, and secondly, we also need to pay attention to the nutrients they need, and at such times, we need to be very careful.

Now the prospect of raising leeches is very good, leeches are easy to raise. Because the ** of leeches is very high now, and the demand is very large, there is still room for growth.

The outlook is not good. Because of the impact of the global epidemic, seafood products are not easy to sell. This kind of thing is not easy to raise, and it has very high requirements for the water quality environment.

I think the prospects are very good. I think it's very promising. The space for the future is huge. But this kind of thing is very difficult to raise.

Tianjin must be very good, this thing is quite expensive. It's relatively easy to raise, but you have to master the relevant skills and knowledge.

Where did you get such old information??? The cost is high, and it is not easy to breed! But if the breeding is good, the profit can also be... The cost of one acre of pond breeding is about 10,000 yuan. How simple is this ...

It's okay, but you have to have the skills and experience. If you don't have words, don't breed! **Very good, the future** is also good, but leech farming technology is still in the exploration stage.

I would like to ask about a locust breeding plant in Hefei, Anhui Province. Thank you'
