How much money can be made by raising an acre of snails, and how many catties can be produced by rai

It is calculated that one acre is equal to 667 square meters.

1) Estimated investment budget for snail farming in paddy fields:

1. Introduction fee: 667 square meters of paddy field stocking 60,000 young snails weigh about 100 kilograms, 4 yuan per kilogram, a total of 400 yuan; 1100 large snails (according to the ratio of 3 males and 8 females, 18 20 grams each), weighing about 21 kilograms, 6 yuan per kilogram, a total of 126 yuan. The total seedling fee is 526 yuan.

2. The cost of cultivating aquatic feed: 1400 kg of manure in 667 square meters (1000 kg of base fertilizer, 4 times of top dressing, 100 kg each time), and the expenditure is 140 yuan.

3. The production cost of live feed such as earthworms is 100 yuan.

4. 50 yuan for disinfectants.

5. 30 yuan for water and electricity, including 22 yuan for water and 8 yuan for electricity.

6. Expenses that cannot be ** (15% of the sum of the above 1 5 items) are total.

The above 1 6 items totaled 973 yuan.

2) Economic benefit analysis:

1. It is beneficial to raise young snails in that year. 7 15 days after early rice transplanting stocking 60,000 snail seedlings, to the late rice harvest has reached the first specification, with a survival rate of 90%, a total of 10,000, an average weight of 10 grams, a total of 540 kilograms. The price of complete ecological breeding is 6 yuan per kilogram, and the total income is 3,240 yuan.

2. The yield of 667 square meters of rice increased by 10%, the annual (two crops) increased by 160 kg, pesticides and fertilizers were saved by 70%, and 667 square meters increased income and expenditure by 150 yuan. A total of 3,390 yuan was received. 2.

Expenditure for the year: 973 yuan. The income and expenditure were offset and the profit was 2417 yuan.

In the first year, 1,100 large snails were stocked, and they were kept in the fish ditch and fish pit to continue to be raised as the second year's snails. Self-breeding and self-raising can save the cost of seedlings and make higher returns.

The yield per mu of snails is generally 3333 kilograms, and the yield of one mu of breeding snails depends on the amount of snails and specific geographical conditions.

The snail is a viviparous animal, the south of the year in April, May and September and November is the breeding period of the snail, each snail can produce 20 30 small snails each time, after the female snail gives birth, it takes 14 16 months to reproduce again, the small snail just produced weighs grams, and can reach more than 3 5 grams after raising 6 months, and can reach about 9 grams in 9 months. It is necessary to selectively fish for snails, and leave more snails, which can be harvested in batches.

When fishing, it is necessary to selectively fish for adult snails, leave more female snails, and harvest them in batches; In midsummer and early autumn, the water temperature is high, and the snails hide in the soil and grass at noon, so it is necessary to pick them up in the morning and dusk, and they can also be drained and picked; For every 100 snails stocked, the annual output can reach 100 kg.

Annual output of snails

Snails are found in most parts of China. Field snails have high requirements for water quality and can be caught in summer and autumn. It is necessary to selectively fish for snails, and leave more snails, which can be harvested in batches.

The water temperature is high in early autumn, and the snails are mostly hidden in the soil and grass at noon, so they must be picked up in the morning and evening, and they can also be drained and picked. For every 100 snails stocked, the annual output can reach 100 kg.

A batch of snails from the snail seed to the harvest, the growth cycle is about 4 months, a year can be harvested three times, each batch can harvest 2000-3000 catties, a year down an average of about 8000 catties, according to 4 yuan catties calculation, the income of snails alone has more than 30,000 yuan.
