What are the feed requirement characteristics of snail (river snail) farming?

I think everyone is very familiar with the river snail, especially given the rapid development of China's late-night snack industry in recent years, the demand for river snails has grown larger and larger, and in the late-night snack industry the market share of river snails is very large, so in recent years the farming prospects for river snails have also been very good.

Feed requirement characteristics of farming river snails

Manure should first be applied to the farming pond to cultivate plankton and provide bait for the river snails. The amount of fertilizer applied depends on whether the pond bottom is fertile or lean.

1. Juvenile snail feed. Two weeks after birth, the juvenile snails should start to be fed; at first egg yolk is suitable, and after 1 to 2 days they can be allowed to feed on natural bait. When river snails feed, they lick the bait with their radula, so when feeding solid bait it must be soaked soft so that it is suitable for feeding.

2. Young snail feed. After the river snails are placed in the pond, start feeding green vegetables, rice bran, fish viscera or tea cake, bean cake, etc. Green vegetables and fish viscera should be chopped and mixed evenly with feed such as rice bran before feeding; rapeseed cake, bean cake, etc. should be soaked until soft so that the river snails can feed on them.

3. Adult snail feed. The feed requirements of adult snails can be divided into 4 periods in a year:

① March to May is the preparation period before mating, when they begin to feed.

② May to mid-August is the spawning and fattening period; appetite increases sharply in the early stage, and in the later stage appetite is sometimes poor due to the effects of spawning and high temperatures.

③ August to mid-October is preparation before hibernation; in the early stage appetite gradually increases, storing nutrients to prepare for hibernation. As hibernation approaches, their food intake decreases.

④ When spring arrives and the river snails begin to wake after hibernation, start feeding organic fertilizer one week before. (5) Both the spawning preparation period and the hibernation preparation period require feeding, and it is suitable to feed 2 times per week. The amount of bait can be flexibly controlled according to the feeding situation of the river snails and the water quality conditions. (6) River snails are best suited to grow within the range of 20 to 26°C. When the water temperature is below 15°C or above 30°C, no bait needs to be fed.

Farming prospects of river snails  

River snail meat is a natural health food rich in nutrients, and abroad it is also known as a beauty food. It contains 10.3% protein and 1.2% fat, and also 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, sea cucumber, etc. River snail meat can nourish kidney yin, improve eyesight and clear the mind, enhance muscle elasticity and refine the skin, etc.  

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 to prevent and treat diseases. At present, naturally grown river snails are far from meeting market demand, and river snail farming grows quickly with high yield, so farming river snails has broad "money" prospects.

Is farming river snails profitable  

River snail is the general term for edible aquatic animals of the family Viviparidae, with many varieties, and common ones include round river snail, river snail, yellow snail, mud snail, fragrant snail, etc. River snail meat is a natural health food rich in nutrients, and abroad it is also known as a beauty food. It contains 10.3% protein and 1.2% fat, and also vitamins, calcium, iron and other elements essential to the human body.

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 to prevent and treat diseases. At present, naturally grown river snails are far from meeting market demand, and river snail farming grows quickly with high yield, so farming river snails has broad "money" prospects. In recent years, as the natural yield of river snails has gradually decreased, the river snail market has kept looking up. At present, artificial farming has begun in areas such as Guangdong and Fujian, and many farmers take river snail farming as a business path and vigorously develop it.

Economic benefit analysis of river snails  

1. Raising juvenile snails gives returns in the same year. 7 to 15 days after early rice transplanting, stock 60,000 river snail seedlings, and by the time of late rice harvest they have reached the size for sale. Calculating at a survival rate of 90%, there are 54,000 in total, averaging 10 g each, for a total of 540 kg. With fully ecological farming at a sale price of 6 yuan per kg, the total income is 3,240 yuan.  

2. Rice output increases by 10% per 667 sq m, with an annual increase (two crops) of 160 kg, pesticide and chemical fertilizer savings of 70%, and an increase in income and reduction in expenditure of 150 yuan per 667 sq m. Total income is 3,390 yuan. 2. Expenditure for the year: 973 yuan. Income and expenditure offset each other, for a profit of 2,417 yuan. In the first year, stock 1,100 large snails and keep them in the fish ditches and fish pits to continue raising as breeding snails for the second year. By carrying out self-breeding and self-raising, the cost of seedlings can be saved, and the returns are higher.

From the above introduction we can see that the growth of river snails is also divided into several stages, and the feed formula required at each stage is different, so its growth habits at each stage are also different, and farmers should therefore pay attention to treating them differently.
