What are the conditions for raising leeches? How to raise leeches indoors

Summary. To breed leeches indoors, you need to build greenhouses and cement ponds. The area of the pool is about 20 square meters, the water depth is meters, and the inlet and drainage outlets are arranged.

It needs to be disinfected before stocking, and the seedlings are planted after 20 days, and about 100 are put per square meter. In daily feeding, snail meat and mussel meat are mainly fed, and animal blood is fed once a week. Building a greenhouse can protect against rain and keep you warm.

What is the survival rate of indoor grasshoppers?

There is no way to judge this, and there is no professional data, because of the various requirements of the people raised in the venue.

How much temperature is better for breeding.

How long does it take to grow it into a finished product.

How profitable is its farming.

The cost of breeding leeches: the land fee is about 1,300 yuan, the introduction fee is about 1,500 yuan, the feed fee is about 700 yuan, the management fee is about 1,000 yuan, and the miscellaneous fee is about 500 yuan, so the cost of breeding one mu of leeches is about 5,000 yuan. Profit from breeding leeches:

The income of one mu of leeches is about 10,000 yuan, and the net profit of one mu of leeches is about 10,000 yuan, excluding the required costs.

Is the introduction of seeds counted? Yes.

1. Water quality management. Water is one of the most important factors for leeches, and the reason why there is less and less water quality in the wild is because many of the water quality has deteriorated and it is no longer able to survive. Leech water to choose natural and pollution-free, some fertilizer water or pesticide content of higher water quality will have a more serious impact on leeches, so farmers should be cautious when choosing water sources.

Secondly, in order to ensure the quality of the water source of the breeding pond, it is best to maintain the circulation of live water for a long time.

2. Breeding density. Don't think that leeches are relatively small and think that leeches can raise a lot per mu, generally speaking, the number of breeding per mu is basically about 2200-2500, and the seedlings are generally about 40-50 catties. Because there is no guarantee that the leeches will be evenly distributed throughout the farm, a little less can maintain the growth rate and quality of the leeches.

Therefore, it is best to divide the breeding site to maintain the uniform distribution of leeches to the greatest extent.

3. Feeding. The common food of leeches is snails, mussels and some animal blood clots, etc., in the early stage, a certain number of snails and mussels are evenly placed in the breeding site, and then some blood clots are supplemented to feed to speed up their growth. Generally, it can be fed once in the morning and evening, and the feeding is often controlled at about 1-2 hours, and a small amount of feeding is given each time, so that the leeches can eat to the greatest extent and reduce the loss of feed.

4. Temperature control. Leeches are very afraid of high temperatures, so breeding sites must have means of temperature control, especially in summer. In the summer, it is best to build some shade nets or put some floating aquatic plants in the water to reduce the chance of direct sunlight contact with leeches.

If the temperature is too high, it is best to increase the depth of the pool appropriately and keep the bottom temperature more suitable for growth.

The breeding of leeches is suitable for raising in swamps.

Because the water level of the marshland is shallow, the aquatic plants are luxuriant, and the bottom layer is organic matter, plankton, etc. As long as the fence is built, leeches can be stocked. It is also suitable for farming in depressions.

There are a variety of weeds here, all of which can be used as bait for leeches. There are also benthic organisms such as snails and mussels. In addition, it is also more suitable for breeding in rice fields, where the water level is shallow, the water temperature is suitable and there is rice shade.

1. Food residues: feed plant residues for leeches to supplement nutrients. 2. Feed:

Leeches are fed special feed for their healthy growth. 3. Small shrimp: Small shrimp is rich in protein, which is conducive to the development of leeches.

4. Earthworms: Earthworms are nutritious meat foods. 5. Hard-boiled egg yolk:

Hard-boiled egg yolks can provide protein for leeches.

Leeches are omnivores, and can be fed with a variety of foods during breeding, such as plant residues, feed, small shrimps, earthworms or cooked egg yolks, etc., and should pay attention to not too much when feeding, and should have a reasonable diet to avoid food accumulation.

Leeches have high requirements for water quality, and natural non-polluting water quality needs to be used during breeding, and the water quality of fertilizer or pesticide content is too high will have a serious impact on the growth of leeches, so it is necessary to be cautious when choosing water sources, and to maintain the circulation of live water for a long time.

Although the volume of leeches is smaller, but the density during the breeding period should not be too large, otherwise it will affect its normal development, reduce the quality, generally the number of breeding per mu of field is 2200-2500, and the number of seedlings is 40-50 catties is appropriate, it is best to divide the breeding site to maintain the uniform distribution of leeches.

Leeches are more afraid of high temperatures, during the breeding period to carry out reasonable temperature control, especially in summer, it is best to build a shade for it, or in the water plankton to reduce the probability of direct contact with leeches, when the temperature is too high, you can increase the depth of the pool to cool down.

Rice paddy interculture. Digging ditches and ditches in rice fields as the main activity places of leeches, generally excavated according to the shape of "well" and "ten", divided into two types: ditch and mud pond. The chute requires uniform distribution, extending in all directions, which is conducive to the growth and foraging of leeches, generally wide meters, water depth meters, and the area of the chute accounts for about 10% of the total area;

The mud pond type is to dig the mud pond inside the paddy field, the mud pond is connected with the paddy field ditch, the ditch width and the ditch depth are about meters, and the depth is about 15% of the paddy field, and the pesticide application of the paddy field is harmful to leeches. Generally, choose high-efficiency and low-toxicity pesticides, do not use chemical fertilizers, and it is better to use animal manure, which is not only conducive to rice harvest, but also a good feed for leeches.

Cement pond culture.

Build a cement pool of about 20 square meters, 3 meters wide, 7 meters long, 1 meter - meter high, water depth meters, do a good job of inlet and drainage facilities, outdoor cement pool needs to put aquatic plants and other plants, so that leeches inhabit. The newly built cement pond can not immediately put the leeches, the alkaline substances of the pool body (Portland cement, calcium hydroxide, etc.) need to go through 20 days of desalination before the seedlings, can not be a one-time seedling, after the overall environmental conditions of the breeding pond tend to the overall balance of the food chain, in order to gradually increase the amount of seeds, generally 100 per square meter.

1. Regulate water quality. Although leeches can grow in sewage, but due to the high density of artificial breeding, the water quality should be kept fresh, and at the same time to ensure a certain amount of dissolved oxygen, when the oxygen content in the water is less than 2 milligrams of liters, leeches will surface and appear uneasy.

2. The water temperature is high in summer, so pay attention to proper water change.

3. Wintering management starts first. Leeches are dormant in winter, and those stocked in early spring have generally grown well and can be processed**. When fishing, the water is released and then scooped up with a net. Select the seeds with large and robust growth, and leave 10 15 kg per mu and put them into the breeding pond for wintering.

4. When the temperature of the thermal insulation pond is above 15 in winter, leeches can feed and grow, so as to shorten the breeding cycle and achieve the purpose of raising throughout the year. When the water temperature of the feeding pond is 15 30, the leech grows well, stops feeding below 10, and affects the growth above 35.

It is said that leeches have strong vitality, but that refers to the low-density conditions of the natural environment, and artificial high-density breeding, leeches are still very prone to problems, such as water quality deterioration, bad weather, etc., which are very easy to lead to a large number of leeches dying or escaping. If you don't have farming experience, even if you have someone to guide you, you can make money in the first year, which is basically impossible.
