How to raise snails and how to deal with them.

1. Aquaculture water: Oncomelania hupensis has strong adaptability and few diseases. As long as you avoid a lot of pesticides and fertilizers, such as many flat rivers, streams, potholes, rice fields, ponds and other ordinary water bodies in rural areas, you can survive well. 2. Stocking of seed snails: It is best to stock the seed snails in the early stage of snail breeding. The sources of seed snails are field collection and market collection. 3. Feeding management: the extensive farming method in natural waters only needs to maintain the fertility of the water body and regularly apply an appropriate amount of organic fertilizers such as manure, chicken manure, cow manure, pig manure or straw.

First, how to raise snails?

1, aquaculture water body

(1) Oncomelania hupensis has strong adaptability and few diseases. Most flat rivers, streams, pits, paddy fields, ponds and other water bodies in rural areas can be used to cultivate Oncomelania snails as long as a large number of pesticides and fertilizers are avoided.

(2) You can also dig special ponds for breeding, and you must choose places with convenient water sources and humus soil to build ponds (if the soil is not suitable, you can apply mixed compost to improve it first).

(3) The thickness of sediment is 10- 15cm, and the area is not limited.

(4) If it is an open water body, a small amount of Azolla and water lilies can be planted on the water surface, or some long vines and vegetables can be planted around the pond. In the water, you can arrange bamboo tails, branches or snails such as stones and grass to hide.

(5) Before the snail is put into use 10 day, quicklime can be applied to the whole pond to remove wild fish, shrimp and other miscellaneous snails at a dosage of 50- 100 kg per mu, and organic fertilizer can be piled up in the water body after 3-4 days.

2. Stocking snails

(1) The stocking of snail species must be completed in the early stage of snail reproduction. There are two sources of snail species, one is field collection and the other is market collection.

(2) Fresh snails with light brown color, thin and complete shell and blunt dome can be selected, and then 0. 1-0.5 kg per square meter can be put into the natural extensive water body, which can increase the seed investment by about 2-3 times.

(3) The cultured Oncomelania hupensis can be stocked independently, or some silver carp and bighead carp can be interplanted, or mixed culture methods such as Oncomelania hupensis and loach can be adopted.

3. Feeding management

(1) In general, extensive farming in natural waters only needs to maintain water fertility, and organic fertilizers such as manure, chicken manure, cow manure, pig manure or straw are regularly applied in ponds to meet the growth needs of snails.

(2) In the case of high-density intensive farming, artificial bait must be fed. Snails have low nutritional requirements, and rice bran, wheat bran and soybean powder can be fed at the ratio of 60%, 25% and 15%.

Second, how to deal with snails?

1, stone snail spits sand

(1) You must not eat snails bought or touched in the pond that day. You can put it in clean water, add some oil, and then put it in a cool place for about 12 hours. If it is midsummer, you must change the water.

(2) This will allow the stone snail to spit out the sand it has eaten. If there is a stone snail floating without spitting sand, it must be picked out.

Step 2 wash snails

(1) Due to the special growth environment of Oncomelania hupensis, there are some algae or parasitic bacteria on the surface of wild Oncomelania hupensis.

(2) This situation can be scrubbed several times with salt water, and stubborn algae should be scraped off with a knife.
