CATDOLL : CATDOLL: What can you do with snails?

1. What is the use of raising snails?

Farmed snails have edible, medicinal and health-care value. Outdoor open-type snail farming models include trench, shed, and courtyard, allowing them to grow and reproduce in a protective circle similar to natural conditions; indoor artificial snail farming should choose a leeward open space, use bamboo or steel bars to build a 20-meter, 3-meter-wide, and 2-meter-high breeding shed, and cover the shed with plastic film.

2. What role do snails play in the soil?

1. As an indicator organism for monitoring environmental pollution.

Snails are in direct contact with soil and plants during their lives and feeding, and can directly absorb metal pollutants from the atmosphere, soil and plants.

However, since snails contain a special protein that can reduce the toxicity of metals, they will not be seriously harmed even if they are inhaled into the snail's body.

Based on this characteristic of snails, measuring the heavy metal content in snail bodies can reflect both the concentration of soil pollutants and the enrichment intensity in the snail bodies.

Therefore, snails can be used as indicator organisms to monitor environmental pollution.

2. Determine the heavy metal content in snails.

There have been relatively systematic studies and analyses abroad on the accumulation of heavy metals and other toxic and harmful substances in snails, but there are few research reports in China.

Analyzing and determining the changes in metal content in snail weight has important practical significance for evaluating the effectiveness of snails in treating environmental pollutants and for the rational use of snails.

There are two methods to determine the metal content of snails:

(1) Determination of the content of metal pollutants in the digestive glands of snails.

Researchers have found that the content of metal pollutants in snail digestive glands is an important indicator of the degree of soil pollution.

By testing this indicator, soil and environmental pollution can be reported and prevented in a timely manner.

Chemical testing of soil contaminated with heavy metals such as cadmium, zinc, copper and lead found that the metal pollutants in the soil in this area were the same as those in the snail's digestive glands.

(2) Determine the content of metal pollutants in snail bodies.

① Equipment for measuring samples:

The materials are mixed samples of cultured adult and juvenile white jade snails.

Take fresh live snails, wash them, treat them at 5°C for 6-8 hours, remove impurities and immediately place them in a 105°C oven to dry until constant weight, grind and sieve them to obtain snail analysis samples.

②Determination method:

It can be measured according to relevant standards.

③Measurement results:

The heavy metal content in the bodies of white jade snails raised in a certain area was measured, and the mercury content was ≤0.1 mg/kg, the lead content was ≤0.5 mg/kg, the arsenic content was ≤0.5 mg/kg, and the copper content was ≥35.2 mg/kg. The results showed that the copper content was seriously exceeded.

3. What is the use of raising snails?

Snails have high nutritional value, low cost, and a variety of uses. They can be made into food, health products, and skin care products, with high economic benefits.

4. What is the purpose of keeping snails in fish tanks?

Snails can be placed in fish tanks. A small number of snails can help clean some algae on the surface of aquatic plants and the walls of the tank, but not too many. They have strong reproductive abilities and will be difficult to remove if there are too many of them, causing harm to the fish and aquatic plants.

Although snails can remove algae, their reproductive capacity is too strong. It does not take too much time for them to fill the entire fish tank. Not only will they occupy the living space of the fish, but some may even endanger the health of the fish.

5. What can snails do in mud ponds?

Snails can loosen the soil, prevent soil compaction, promote water absorption and flow, and directly absorb metal pollutants in the atmosphere, soil and plants. By detecting snails in a region, the metal pollution of the soil in that region can be indirectly detected.

6. What are the main uses of snail farming?

For food: Snail is a high-protein, low-fat food. 100 grams of snail meat usually contains 18 grams of protein, 5 grams of fat, and 7 grams of carbohydrates. In addition, snail meat also contains rich amino acids, calcium, alkaloids, phenols, lactone, coumarin, organic acids, vitamins and other substances.

As feed: The digestive enzymes in snails can promote the decomposition and conversion of feed by livestock.

As decoration: snail shells can be processed into various shell carvings.

7. What are the uses of snails?

Snails are salty and cold in nature, so farmed snails are mostly used as traditional Chinese medicine. Generally, live snails can be caught in summer and autumn, allowed to rest and excrete feces, then killed with boiling water and dried in the sun. They can be made into powder or snail powder, which means removing impurities from the dried snails and directly crushing or grinding them with tools for use; they can also be made into calcined snails, which means putting clean snails into a calcining furnace, calcining them with high heat until they are red, taking them out and letting them cool for use.

8. What is the use of snails in fish tanks?

1. Watch.

2. Control algae.

3. Clean.

4. Eliminate excessive numbers of other snails.

5. Aquarium biodiversity

Although snails can remove algae, their reproductive capacity is too strong. It does not take too much time for them to fill the entire fish tank. Not only will they occupy the living space of the fish, but some may even endanger the health of the fish.

If you want to clean up algae, you can raise some algae-eating fish, such as moss mice, black-line flying foxes, elf fish, etc. These fish are not large in size and are very convenient to raise together.

9. What can snails be used for?

Snails can be used for food and medicine, and are of high value. They are nutritious, delicious, and are high-protein, low-fat, low-cholesterol, and high-grade nutritional tonics rich in more than 20 kinds of amino acids.

Snails are terrestrial molluscs belonging to the class Gastropoda. There are many species of snails all over the world. According to relevant data, there are 40,000 species of snails all over the world. Snails are distributed in all provinces and regions of my country, living in forests, shrubs, orchards, vegetable gardens, farmlands, parks, gardens, temples, mountains, plains, hills and other places. However, there are very few species that are worth raising and eating. As a high-protein, low-fat, high-quality food and animal protein feed for humans, snails are increasingly valued by people.

10. What role do snails play in the ecosystem?

1. Snails are consumers in nature, which means they live on the leaves of plants.

2. Secondly, snails are low-end organisms in the food chain and are eaten by other organisms such as birds. Snails have a very wide range of foraging, mainly eating various vegetables, weeds and melon and fruit peels. Leaves, stems, buds, flowers, and juicy fruits of crops.

They can eat all kinds of green grass, highland barley feed, succulent feed, bran feed, and cake feed. In spring, they can be fed with cabbage, green vegetables, lettuce and other plants, and in summer, they can be fed with various melon and fruit peels, sugar cane, sunflower leaves, etc.

In autumn and winter, feed them with vegetable leaves, potato chips, carrots, etc. Snails like to live in a dark, humid, loose and humus-rich environment. They hide during the day and come out at night. They are most afraid of direct sunlight and are sensitive to the environment.
