How to raise leeches, how to raise leeches indoors

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.

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.

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.

Summary. When raising leeches, it is necessary to adjust the water quality, keep the water clean, and also need to ensure a certain amount of dissolved oxygen, if the oxygen content in the water is less than 2 mg per liter, the leeches will be turbulent, and the water should be changed frequently when the water temperature is too high in summer.

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.

Fruit large-scale breeding of leeches, to choose shelter from the wind and sun, irrigation and drainage conditions of good location to establish a breeding pond, the general width of the pond is 3 meters, the depth is 1 meter, the length is not limited, the bottom of the pond can be put into some stones and branches, if it is a small-scale breeding, you can directly use puddles, ponds and other breeding.

Leech species are more suitable for artificial breeding is the leech, which usually lives in rice fields, ponds, jungles, can put about 10,000 leeches per cubic meter, in the selection of species must choose the growth of robust, no damage to the leech.

Leeches feed on mussels, turtles, earthworms, snails and the blood of mammals, artificial breeding can be mixed with all kinds of blood and feed, grass meal, etc., and then fed to leeches, the blood of general animals is only fed once a week, and live snails can be put into the breeding pond at ordinary times for leeches to eat.

When raising leeches, it is necessary to adjust the water quality, keep the water clean, and also need to ensure a certain amount of dissolved oxygen, if the oxygen content in the water is less than 2 mg per liter, the leeches will be turbulent, and the water should be changed frequently when the water temperature is too high in summer.

Is it not a greenhouse, but a cement pool in the factory to raise?

OK. It is fifteen meters wide and has ventilation windows on all sides.

You can raise. Can you not use sunlight without affecting it?

There is no impact. Why.

Everything depends on the sun.

In the open environment, the growth of leeches is particularly susceptible to the influence of many environmental factors (water quality, temperature, sunlight, natural enemies, etc.), resulting in low survival rate of leeches, which seriously affects the yield and economic benefits. Indoor cultivation can provide a stable and controllable growth environment for leeches, and special light treatment can significantly improve the growth rate and survival rate of leeches.

The conditional sunlight cannot be very large, and there is no condition to bask in the gentle sunlight with Equika.

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 the general raw wax that is stocked in early spring grows well, and can be processed by banquet stools**. When fishing, the water is released and then scooped up with a net.

Select large and robust seeds, 10 to 15 kg per mu should be left, and the wheel shed should be put into the breeding pond for wintering;

4. When the temperature of the thermal insulation pond is above 15 degrees Celsius 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 between 15 and 30 degrees Celsius, the leeches grow well, stop feeding below 10 degrees Celsius, and affect their growth above 35 degrees Celsius.
