What are the nutritional requirements for snail farming?

If you want to gain the wealth you desire from snail farming, you first need to understand some snail farming techniques, as well as some problems you may encounter during farming and the methods to solve them. Second, you need to analyze the snail market conditions and find the best timing.

What are the nutritional requirements for snail farming

1. Protein. Protein is a nutrient necessary for the growth of golden apple snails, for maintaining life, and for forming body tissues. It not only constitutes their physique, but also serves as a component of enzymes and hormones, playing a very important role. Main sources of protein: Protein is divided into two major categories: plant protein and animal protein. Plant protein mainly comes from grains, beans, etc.; animal protein mainly comes from livestock meat, poultry meat, fish, eggs, milk, etc.

2. Fat. Main functions of fat: supplying heat. Fat tissue helps regulate body temperature, prevents body heat from dissipating, and protects internal organs. Therefore, during growth and development, snails must continuously obtain a certain amount of fat from feed to meet physiological needs.

3. Carbohydrates. Carbohydrates in bait are mainly starch and cellulose. The main function of carbohydrates is to supply heat energy. All nerve tissue, cells, and body fluids contain sugars. Carbohydrates can assist fat oxidation and promote growth and development.

4. Vitamins. Vitamins are a class of compounds essential for maintaining normal physiological functions in snails. There are many types of vitamins, usually divided into two major categories: fat-soluble and water-soluble. Fat-soluble vitamins include vitamin A, vitamin D, vitamin E, and vitamin K; water-soluble vitamins include B-complex vitamins and vitamin C.

5. Energy. To maintain life and metabolic activities, snails must obtain energy from bait every day to meet the body's needs. The main energy substances in feed are carbohydrates, lipids, and proteins. They release energy in the body through biological oxidation by combining with oxygen taken in through the gills.

6. Inorganic salts and trace elements. Although inorganic salts and trace elements cannot supply the body with energy, they are of great significance in normal life activities. They not only constitute tissue components but are also substances necessary for maintaining normal physiological functions, so meeting snails' needs for inorganic salts and trace elements is extremely important. All chemical elements other than ammonia, nitrogen, hydrogen, and carbon are collectively called inorganic salts. Among them, calcium, magnesium, potassium, sodium, phosphorus, sulfur, and chlorine are present in relatively large amounts; others such as iron, iodine, copper, zinc, manganese, and cobalt are present in extremely small amounts, but they have a great impact on the body's nutrition and functions.

Nutritional value of river snails  

1. River snail meat is rich in protein, vitamins, essential amino acids, and trace elements. It is a typical natural animal-based health food with high protein, low fat, and high calcium.  

2. Vitamin A in river snails can help regulate the eyes' ability to adapt to external light, thereby reducing the occurrence of night blindness and vision decline, and it also helps treat various eye diseases such as dry eyeballs and conjunctivitis.  

3. River snails are rich in protein and have the effects of maintaining potassium-sodium balance, eliminating edema, improving immunity, lowering blood pressure, and buffering anemia, which is beneficial to human growth and development.  

4. River snails are rich in calcium. Calcium is the basic raw material for bone development and directly affects height.  

5. River snails are rich in copper. Copper plays an important role in blood, the central nervous system, the immune system, and the development and function of hair, skin, the brain, liver, heart, and other internal organs.  

6. River snails are rich in iron. Iron is an essential component of blood production and is suitable for the treatment of iron deficiency anemia.  

7. River snails have the highest protein content and the lowest fat content, making them a leader in nutrition among shellfish and earning them the reputation of "pearl on the plate." 

River snail farming techniques 

River snails mostly reproduce naturally. For artificial farming, they can be picked from paddy fields, wild rice stem fields, and muddy ditches, or bought from the market, and then live snails with light brown color, thin shells, round bodies, and blunt tails are selected as breeding snails. Generally, river snails weighing 15-25 grams reach sexual maturity and can reproduce at temperatures above 15°C. Female snails are large and round, while male snails are small and pointed.  

1. Stocking and reproduction  

The optimum growth temperature for river snails is 20-25°C. If it is lower than 15°C or higher than 30°C, river snails stop feeding; below 10°C, they burrow into the soil to hibernate. South of the Yangtze River, stocking can be done from March to November. If stocking in a natural area, 11 breeding snails per square meter is sufficient (3 males and 8 females). If a pond is dug for single-species farming, 100-500 can be stocked per square meter, and the water depth should preferably be 0.8-1 m. A layer of more than 10 cm of silt should be retained at the bottom of the pond to facilitate crawling, feeding, and resting by the river snails. When stocking, males and females can be placed together and they will reproduce naturally.  

2. Feeding and rearing  

River snails are omnivorous animals. Rice bran, vegetable scraps, melon leaves, animal carcasses, and commercial feed can all be fed to them. Generally, aquatic plants, soil humus, and vegetable and melon peels are their staple food. In fertile paddy fields, fish-snail mixed farming, or water surfaces where red azolla, green azolla, water hyacinth, and similar lowland plants are grown, feed can be given less or not at all.  

3. Reproduction management  

River snails are viviparous animals. In the south, April-May and September-November each year are the breeding periods. Female snails generally give birth in batches, and each river snail can produce 20-30 small river snails each time. After giving birth, the mother snail needs 14-16 months before it can reproduce again. Newly born small snails weigh 0.5-1.5 grams, can reach more than 3-5 grams after 6 months of rearing, and can reach about 9 grams by 9 months.  

4. Catching and harvesting  

When catching river snails, adult snails should be selectively collected, and more female snails should be retained. Harvesting can be done in batches. In midsummer and early autumn, when water temperatures are relatively high, river snails mostly hide in soil and among grass at noon, so they must be picked in the morning and evening, or picked after draining the water. For every 100 female snails stocked, annual production can reach 100 kg.

Market prospects for farming river snails  

River snails are the general term for edible aquatic animals in the family Viviparidae. There are many varieties, and common ones include round river snails, river snails, yellow snails, pond snails, and fragrant snails. River snail meat is a nutrient-rich natural health food, and abroad it is also known as a beauty food. It contains 10.3% protein and 1.2% fat, as well as vitamins, calcium, iron, and other elements essential to the human body. The nutrition of river snail meat is superior to that of chicken, duck, goose, and pork, and is no less than that of crucian carp and sea cucumber.  

River snail meat can nourish kidney yin, improve eyesight, clear the mind, enhance muscle elasticity, and refine the skin. River snails can be used as an everyday meat dish, and can also be processed into a series of foods, used to cook many medicinal dishes, and used to prevent and treat diseases. At present, naturally growing river snails are far from meeting market demand, and river snail farming has fast growth and high output. Farming river snails has broad "money" prospects. In recent years, as the natural output of river snails has gradually decreased, the river snail market has continued to look promising. At present, artificial farming has begun in Guangdong, Fujian, and other regions, and many farmers have taken river snail farming as a path to entrepreneurship and are vigorously developing it.

Although farming river snails is relatively easy to talk about and is not as cumbersome as other types of farming, truly doing this well still requires attention to a lot of technique. We all know that river snails are rich in nutritional value, and the market is currently in a state of supply falling short of demand, so the development prospects for river snail farming are still quite good.
