Treatment of shelling disease of farmed snails

In the process of snail culture, it is very important to prevent and treat diseases. Only by controlling the occurrence of diseases can we effectively increase the output of snails and reduce costs and increase profits. therefore, the importance of disease must not be ignored in the process of breeding.

Etiology of shelling disease of field snail

The feed is single, and there is a lack of elements such as calcium, phosphorus and potassium. Snails like to live in waters with cool winter, soft sediment, rich bait and fresh water quality, such as lakes, marshes, field valleys or slow-flow ditches with luxuriant water plants, especially in places with micro-running water and mixed food habits. They often feed on microorganisms and humus in the soil and phytoplankton, young aquatic plants and moss in the water, as well as artificial feed. Such as fruits and vegetables, vegetable leaves, rice bran, wheat bran, soybean flour (cake) and various animal scraps, and like nocturnal activities and feeding, the most suitable temperature for growth is 20-27 ℃.

Symptoms of shelling disease of field snails

The shell falls off and the internal organs are exposed in severe cases.

Treatment of shelling disease of field snail

① sprinkles humus to supplement calcium.

② is fed with stupid calcium feed, such as shell powder, bone powder, eggshell powder and so on.

Control of diseases and insect pests of field snail

Although snail is a kind of organism with strong disease resistance, it will also be infected with some diseases and insect pests because of its high density, water quality and other reasons.

Snails are generally suitable for breeding in rice fields, shallow ditches, lowlands, wetlands and other places. Field snails do not have high requirements for breeding sites, generally with a little land rectification in shallow water, soft mud bottom waters with a lot of humus can be cultured, and it will be better to have certain micro-flow conditions.

1. The suitable living temperature of field snail culture is 10-40 ℃, and the optimum temperature is 20-28 ℃. More than 40 ℃ will cause death, and less than 10 ℃ will go into hibernation. Attention should be paid to the prevention of high temperature in summer, because the water in the paddy field is shallow, the water temperature may reach the upper lethal temperature in summer, and the content of organic matter in the bottom of the mud overwintering in winter should not be too high, otherwise it is easy to produce toxic substances and affect the snail overwintering.

2. Field snails are sensitive to the amount of dissolved oxygen in water. Normal life requires dissolved oxygen in water to be more than 4 milligrams per liter. When it falls to 3.5 milligrams, appetite will decline, and when it drops to 1.5 milligrams, it will cause death.

3. In field snail culture, the breeding season is from June to July (where conditions permit, an egg will be laid in autumn). If you consider breeding yourself, it is best not to raise carp in the rice field where field snail is raised, otherwise the small field snail will be eaten by carp.

4. The use of pesticides in rice fields should not be used as much as possible; that is, low toxic pesticides should be used in combination, and should be used in sunny days; it should be used in half of rice fields.

5. Organic fertilizer can be used regularly in the growing season, the principle is a small amount of multiple times, should not be fertilized too much at one time.

6. In the process of snail culture, it is best to have a certain micro-running water environment to ensure the dissolved oxygen in the water, but we must pay attention to the water source and do not use the water source with pesticides.

7. In field snail culture, mixed culture with leeches, Loach and Monopterus Albus can be considered, and the economic benefit is better.

As for the relevant information about snail diseases, the editor has given you a general introduction. I hope these will be useful to the friends who cultivate snails. And mastering certain methods to prevent and treat diseases are some necessary skills for farmers.
