Cost and profit of raising snails
Calculated by an acre equal to 667 square meters.
(1) Estimated investment in snail culture in paddy fields:
1, introduction fee: 60,000 young snails in 667 square meters paddy field weigh about 100 kg, 4 yuan per kg, ***400 yuan; Stocking large snails (each18-20g according to the ratio of 3 males and 8 females)100, weighing about 2 1 kg, 6 yuan per kg, *** 126 yuan. The total seedling fee is 526 yuan.
2. Cost of cultivating aquatic feed: 667 square meters of manure 1400 kg (base fertilizer 1000 kg, topdressing 4 times, each time1000 kg), expenditure 140 yuan.
3, earthworm and other live feed production expenses 100 yuan.

5. Water and electricity in 30 yuan, including 22 yuan for water and 8 yuan for electricity.
6. Unpredictable expenditure (sum of the above 1~5 items 15%)*** 126.9 yuan.
The above 1~6 items total 973 yuan.

(2), economic benefit analysis:
1, it is beneficial to raise young snails in the same year. 60,000 snail seedlings were released 7~ 15 days after early rice transplanting, and by the time of late rice harvesting, they had reached the specifications for sale. Based on the survival rate of 90%, there were 54,000 snails, with an average weight of 10 g and ***540 kg. The price per kilogram of completely ecological farming is 6 yuan, and the income of * * * is 3240 yuan.
2. Rice production increased by 667 square meters 10%, annual (two crops) increased by 160 kg, pesticides and fertilizers were saved by 70%, and 667 square meters increased income and reduced expenditure 150 yuan. The total income is 3390 yuan. 2. Expenditure of the year: 973 yuan. Break even, with a profit of 24 17 yuan. In the first year, large snails 1 100 were stocked, and they were kept in fish ditches and fish pits to continue feeding as seed snails in the second year. Self-propagation and self-cultivation can save seed money and have higher income.
Snail culture technology
1. The technical points of artificial culture of snails are as follows.
life habit
Snails often inhabit lakes, ponds, paddy fields and slow-flowing rivers with warm winter and cool summer, soft subsoil and rich bait. Its optimum growth water temperature is about 20 ~ 25℃, and it stops feeding when the water temperature reaches below 15℃ and above 30℃. When the temperature is below 10℃, it will go into hibernation, and when the water temperature returns to above 15℃, it will go out to eat again. Artificial culture of snails can be raised in special ponds, natural paddy fields, swamps and ditches, and mixed with fish. However, the aquaculture water is required to be non-toxic, harmless and pollution-free. If rice fields are used for farming, pesticides should not be used and plows should not be used, and iron wires or plastic screens should be installed at the inlet and outlet for control.
Pond selection
It is required to choose an area ranging from 3 to 20 mu, with a pool depth of 1- 1.5 m, 1:3. The bottom material of the pond is fat, but not too deep, and there is no requirement for the river water around the pond. As for the old pond, due to the lack of beach feet, according to the habits of snails, snails like to live on the sediment with less silt. According to this feature, it is suggested that ponds and ridges can be paved to increase the adaptive area of snails. There is another way: use nets to stand around to further increase the snail culture area.
Pond cleaning
After the pond is selected, it is necessary to clean up the fish pond, do a good job in the pond ridge, and remove excessive silt, especially at the foot of the beach. If possible, it is best to suck mud.
Pond disinfection
It is completely forbidden to use pond cleaning. Generally, it can be disinfected by pond cleaning, but quicklime is the best. The dosage is water (30-50 cm)100-150 kg/mu and anhydrous 50-75kg/ mu. Quicklime cleaning pond has the following advantages: ① increasing PH value; ② increase the quality of Ca; ③ Water quality can be adjusted; ④ Sterilization can be carried out.
Selection of snail species
Appearance requirements: the tip of the snail is short and swollen, the shell is slightly prickly, and the cockroach is slightly red; ② Specification: 60- 100 capsules/kg; ③ Quality requirements: When the snail is frightened, it can be quickly retracted into the shell, free from diseases, injuries and insects.
Stocking time
After the medicinal properties disappeared, stocking began in the first 15 days, which ended around March 20.
