Detailed Explanation of Leech Farming Techniques and Management Key Points

Leech farms are generally chosen in places with strong wind shelter and suitable light, then ponds are built, the selected seedlings are placed in the ponds, and an appropriate amount of water is added. A large number of water hyacinths or duckweed can be planted in the pond, and some field snails or feed are fed daily at a ratio of 50kg/mu, then the water level and growth conditions should be observed more every day to ensure the healthy growth of the leeches. When they grow to more than 15g, they can be harvested and sold.

Precautions for farming leeches:

1. The survival rate of leech seedlings is relatively low, and they are not easy to breed across generations. Therefore, attention should be paid to selection when choosing seedlings. To have a good harvest within one year of stocking, it is necessary to choose robust leeches of more than two years old as seedlings. The larger and more robust the seed leeches, the higher the egg production, hatching rate and survival rate.

2. Before farming leeches, the water quality must be investigated. If the water source is polluted, it may cause all the leeches to die.

3. Anti-escape work should be done well at the bottom of the breeding pond, because leeches especially like to burrow into the mud. With a little carelessness, they will escape without a trace.

4. Although leech farming is currently an industry that the state attaches importance to and supports, in recent years it has been impacted by the market economy and affected by the climate environment, and it carries certain risks. Before farming, it is necessary to fully understand the local market conditions, and then make a choice according to one's own conditions.

The above is the relevant introduction to leech farming techniques. I hope it is helpful to everyone.
