Farmed snails

Snail is a traditional aquatic product in China. It is fresh and delicious, with unique flavor, rich in protein and fat, and phosphorus, calcium, iron and various vitamins. It is popular with consumers. The snail's living environment is not limited, and farmers can use small water and rice fields for breeding.

First, the venue selection. The snail breeding site needs to choose a place with sufficient water, good water quality, humus soil and convenient transportation. It is best to have micro-flowing water.

Second, build aquaculture ponds. Aquaculture ponds are generally 1.5-1.6 meters wide and 10-15 meters long, depending on the terrain. Around the rear of the breeding ponds, it is about 50 centimeters high. Two water inlets were opened at the pool, and a block was installed to prevent the snails from escaping. At the same time, aquatic plants such as white peony, water hyacinth, and duckweed are planted in breeding ponds to create a good living environment for snails.

Third, stocking density. In general, 100-120 snails are stocked per square meter. At the same time, five-tailed summer carp and carp species are cultivated per square metre for three-dimensional cultivation. The stocking time is generally around March.

Fourth, fertilizer feeding. The breeding ponds were first fed with human and animal manure before stocking to cultivate plankton and provide feed for snails. The amount of fertilizer depends on the situation of the bottom of the culture tank. After the snail enters the pond, it is fed with green vegetables, rice bran, fish giblets or rapeseed cakes, and bean cakes. Vegetables and fish viscera should be chopped and mixed with rice bran and other feed and fed. Rapeseed cakes, bean cakes, etc. must be soaked before feeding to facilitate better feeding. The feeding amount depends on the feeding condition of snails, and is generally fed at 1%-3% of the total amount of snails and fed once every 2-3 days. Feeding time is in the morning, and the feeding position does not have to be fixed. Different types of bait are fed alternately. When the temperature is lower than 15 °C or higher than 30 °C, do not have to feed.

Fifth, water quality management. The aquaculture water should be frequently injected with fresh water to regulate the water quality. The aquaculture should be adopted during the high temperature season, and the micro-fluid culture should be adopted during the spring and autumn. The depth of the culture pond needs to be maintained at about 30 cm. In addition, adjust the pH of the water. When the pH value of the pool water is low, 0.15-0.2 kg of lime is applied per square meter, and it is sprinkled once every half month to keep the pH of the pool water at 7-8.

Six, winter management. When the water temperature dropped to 8-9°C, snail began to hibernate. During hibernation, the snail used the top of the shell to drill the soil and only left a circular hole on the soil surface, and bubbles appeared from time to time. During the winter, snails do not eat, but the water depth of the culture pond still needs to be kept at 15 cm. Generally, water is changed every 3-4 days to maintain sufficient oxygen content.

Seven, fishing listed. After a year of careful breeding, snails can weigh more than 10 grams. When catching, they can be fished in the dry pool and take a large stay. At the same time, attention should be paid to the selection of individual large snails for the cultivation of the snails to prepare for the breeding of the snails in the following year.
