Where is suitable for breeding leeches?

Because the water level in the swamp is shallow, the water plants are lush, and the bottom layer is organic matter, plankton and so on. As long as the fence is built, leeches can be released. It is also suitable for farming in lowlands. There are all kinds of weeds here, which can be used as bait for leeches. There are benthic organisms, such as snails and mussels. In addition, it is also suitable for rice field cultivation. The water level in paddy field is shallow, the water temperature is suitable, and the rice is shaded.

Precautions:

Although leeches can grow in sewage environment, due to the high density of artificial culture, the water quality must be kept fresh and a certain amount of dissolved oxygen must be ensured. When the oxygen content in water is lower than 2 mg/L, leeches generally surface and become uneasy. When the water temperature is high in summer, we must pay attention to changing the water properly.

Leeches hibernate in winter: leeches are stocked in early spring to a size that can be processed and sold in winter. Pay attention to releasing water before fishing with a net. Pay attention to choose large and robust seeds, leave 10- 15 kg per mu, and finally put them in the breeding pool for wintering.
