1. Site: paddy fields, ponds, etc. when leeches are cultivated. It needs to be converted into a breeding pond, and an isolation net should be installed around the pond. 2. Density: More than 80,000 leeches can be put in each acre of pond at most. 3. Temperature: Leeches like temperature, and the water temperature should be controlled between 15-30 degrees Celsius. 4. Feeding: When feeding leeches, put snails, shells, pig blood, etc.

How to breed leeches 1, site construction

If you want to preserve leeches, you should choose a suitable place. According to the characteristics of this animal, old ponds, ditches or paddy fields can be used for reconstruction. Be careful that the water level is not too high to prevent leeches from landing. Fine-hole isolation nets should be installed at the water inlet and outlet to prevent leeches from escaping.

2. Curing density

The breeding density of leeches should not be too high. If too many leeches are cultivated in too narrow a space, it will not only become difficult to raise and maintain, but also lead to a large number of leeches breeding, which may cause congestion on the shore, large-scale death or pollution. Therefore, only about 80,000 leeches can be put in an acre of water.

3. Environmental control

Leech is a cold-blooded mollusk, which is suitable for living in a warmer environment. If you suddenly encounter low temperature, you are likely to die in a large area. Therefore, the temperature of the pond for cultivating leeches should not be too high, and it should be kept between 15-30 degrees Celsius, and some floating plants should be planted to shade the water to ensure that the water body is relatively clean.

4. Feed transportation

Leeches don't eat plant feed. They only eat the blood of live animals to make a living. Therefore, when feeding leeches, it is best to use snails or shells that are easy to buy and suitable for leeches. You can also put some bloody wooden blocks into the pond every week and take them out in time after two days.
