1. Cost analysis

(1) Introduction: One acre of land requires 200kg of snails (about 60,000). Calculated based on the price of 4 yuan/kg, one *** It costs about 800 yuan.

(2) Feed: Aquatic feed costs about 140 yuan, and live feed such as earthworms costs about 100 yuan, totaling 240 yuan.

(3) Medicines: It costs about 50 yuan per mu.

(4) Water and electricity: approximately 30 yuan per mu.

2. Income analysis

(1) The survival rate of young snails is calculated as 90. In the end, approximately 54,000 adult snails can be harvested. Each adult snail weighs an average of 10g. The total About 540kg of snails can be obtained.

(2) Calculated based on 6 yuan/kg, you can finally get 3,240 yuan.

3. Profit

The final profit is approximately 3240-1120=2120 yuan.

Snail is a common amphibious soft-bodied reptile. Especially in rural areas, they are very active in some rice fields, streams, and rivers. However, in recent years, there have been fewer and fewer field snails due to various reasons. The main reason is that farmers use fertilizers and spray pesticides in farming, and some pollution. Water quality sources, etc. Although there are fewer snails, they are more expensive and easier to breed.

Snails are an indispensable dish in the late-night snack recipes of all provinces in my country. Therefore, the market for snails in our country is very large, and there is a huge demand for its output. Therefore, it is possible to make money by cultivating snails.

What conditions are needed to raise field snails

1. Breeding environment

(1) The water body for breeding must be non-toxic and pollution-free. If rice fields are used to raise field snails, The use of pesticides should be avoided as much as possible.

(2) When the dissolved oxygen content of the breeding water is below 3.5mg/L, the snail’s desire to eat decreases; when the dissolved oxygen content is below 1.5mg/L, the snail will die. Therefore, it is best to use semi-flowing water for breeding.

(3) The thickness of the bottom mud at the breeding site should be controlled at about 10-15cm. If it is an open water body, a small amount of water lilies can be planted on the water, and branches, stones, etc. can be arranged in the water.

(4) The depth of the water body is kept at 30-40cm, the water is changed about 1-2 times a week, and the pH of the water body is controlled between 7-8.

(5) 10 days before feeding the seed snails, use 50-100kg of quicklime per acre to remove wild fish, shrimp and other snails. After 7-10 days, apply 450-500g of chicken manure and straw segments per square meter (chicken manure 75, straw 25) to cultivate water quality.

2. Feeding

(1) The feed formula of field snails: 60% rice bran, 25% wheat bran, 15% soybean meal, or 60% rice bran, 20% fish meal, and 20% corn.

(2) In an environment of 20-28℃, feed once every 2 days, and the amount of each feeding is 2-3 of the body weight of the snail. In an environment of 15-20℃, 28-30℃, feed twice a week, and the amount of feeding each time is 1% of the body weight of the field snail. In environments where the temperature is below 15°C or above 30°C, feed a small amount or not at all.
