Leech culture technique

Leech farms are generally selected in places with strong wind shelter and suitable light, then build a pool, put the selected seedlings into the pool, and add the right amount of water. A large number of water hyacinth or duckweed can be planted in the pond, and some field snails or fodder are fed according to the proportion of 50kg/ mu every day, and then observe the water level and growth situation every day to ensure the healthy growth of leeches, which can be fished and sold when they grow to more than 15g.

Points for attention in breeding leeches:

The main results are as follows: 1. the survival rate of leech seedlings is low, and it is not easy to reproduce every other generation. Therefore, attention should be paid to the selection of seedlings. If you want to have a good harvest within a year after planting, you must choose strong leeches over two years old as seedlings. The bigger the leech is, the stronger it is, and the higher the fecundity, hatching rate and survival rate are.

2. Check the water quality before breeding leeches. If the water source is polluted, it may lead to the death of all leeches.

3. Do a good job of escape prevention at the bottom of the aquaculture pond, because leeches especially like to drill into the mud. If they are not careful, they will escape without a trace.

4. Although leech breeding is an industry valued and supported by the state, it has been affected by the impact of market economy and climate environment in recent years, so it has certain risks. It is necessary to fully understand the local market situation before breeding, and then choose according to your own conditions.

The above is the introduction of leech breeding technology, I hope it will be helpful to everyone.
