Scientific name Cipangopaludina chinensis Gray, commonly known as snail, field snail, field Ying, fragrant snail. Mollusca, Gastropoda, Ctenophora, Conchidae, Cipangopaludina chinensis Gray, are distributed in all freshwater waters of China. Foreign distribution in North Korea, North America and so on.
Morphological characteristics of medium-sized individuals, shell height of about 44.4 millimeters, 27.5 millimeters wide. The shell is nearly broadly conical, with 6-7 spiral layers, each of which expands outward. The height of the spiral part is greater than the height of the mouth of the shell, and the body spiral layer is obviously expanded. Shell tip. Suture line deeper. The shell surface is non-slip and non-ribbed, yellowish brown. Mouth of shell nearly ovoid, margin complete, thin, with black border. The insult is a horny lamella, smaller than the shell mouth, with concentric growth lines, and the operculum nucleus is located in the center of the inner lip.
Biological characteristics living in freshwater lakes, reservoirs, ditches, rice paddies, ponds, with a broad gastropod crawling, dry, cold, heat has a great ability to adapt to the dry, cold, heat, when the dry environment will be the soft part of the shell into the shell, the operculum will be the mouth of the shell sealed or drilled into the mud. It hibernates in the mud in winter and emerges again in the warmth of the following spring. Feeds on leaves of aquatic plants and low-grade algae. Eggs are born in the womb and fertilized in the body, and the number of eggs carried by the female snail varies from 10 to 100. Developed into young snails, discharged one after another, young snails in the water line free life, young snails grow to about a year that reached sexual maturity.
Economic value of meat for food, flavor, high nutritional value. Frozen snail meat is also for export, but also for livestock feed. It is also a natural bait for mackerel and carp, and the shell and meat can be used for medicinal purposes.
Sweet, salty, cold. The same as the Chinese round snail and so on.

Fukushou snail
Name: Fukushou snail
Currently listed in China's first foreign invasive species.
Synonyms: big bottle snail, apple snail,
Scientific name: Amazonian smail;Ampullaria gigas spix
Family: Apple snail family
Origin: All over China
Habitat: Streams, ponds, paddy fields
Size: 7 cm or so.
Description: Native to Argentina, the eggs are bright red and often cling to the shore.
The snail belongs to Mollusca, Gastropoda, Mesogastropoda, Bottle Snail, Bottle Snail. The snail is native to the Amazon River Basin in South America and was introduced into China in 1981. Its meat is tender and delicious, rich in protein, carotene, a variety of vitamins and minerals, is a delicacy on the table, due to the low fat content, is high blood pressure, coronary heart disease patients with quality tonic. In addition, it is also the feed for some precious aquatic animals. Fukushou snail individual large, wide range of food, adaptability, fast growth and reproduction, high yield, all parts of China have breeding. Consumption of insufficiently heated Fukushou snails may cause parasites such as the Guangzhou tubular nematode infection in the human body.
I. Morphological Characteristics
The whole body of the snail consists of five parts: the head, the foot, the visceral sac, the coat membrane and the shell. The head is cylindrical with a pair of anterior and posterior tentacles, the eyes are located at the base of the posterior tentacles, and the mouth is located on the ventral surface of the muzzle. The ventral surface of the head is a fleshy foot, the foot surface is wide and thick, and it can crawl on the pool wall and plant stems and leaves. The shell is short and round, large and thin, the shell is right-handed, there are 4 to 5 conch layers, the body conch layer is expanded, the spiral part is very small, the shell surface is smooth, mostly yellowish brown or dark brown. The umbilical aperture is large and deep, the operculum is a brown horny sheet with concentric growth lines, and the nucleus of the operculum is biased to one side of the conchial axis. The coat membrane is thin and transparent, wrapping the entire visceral sac, and there is a thin film-like lung sac on the dorsal surface of the coat cavity, which can directly breathe oxygen in the air and has the function of assisted respiration. The lung sac is inflated to enable the snail to float on the surface of the water, and when it encounters disturbance, it will expel gas and sink rapidly. The male snail's reproductive pore opens at the tip of the copulatory apparatus, and the female snail's reproductive pore opens in the outer coat cavity.
Two, living habits
Fusilier snails like to live in fresh water, sufficient bait in fresh water, more clusters in shallow water around the edge of the pool, or adsorption in the aquatic plant stems and leaves, or floating on the water surface, can leave the water for a short period of time to live. The optimal water temperature for growth is 25 to 32 ℃, more than 35 ℃ growth rate decreased significantly, the highest critical survival water temperature of 45 ℃, the lowest critical water temperature of 5 ℃. Fukushou snail has a wide range of diet, is mainly plant bait omnivorous snails, the main diet of duckweed, vegetables, fruits and melons, etc., especially like to eat food with a sweet flavor. Artificial feeding conditions, like to eat corn, bran and other concentrate feed, young snails to fine pimple, humus, concentrate feed. Under starvation, adult snails will also eat young snails and snail eggs.
Three, reproductive habits
Fusiliers are dioecious, in vivo fertilization, in vitro development of oviparous animals, good feeding conditions, 3 to 4 months of age up to sexual maturity. March to November each year for the breeding season, including May to August is the breeding season, the appropriate water temperature of 18 ℃ ~ 30 ℃. Mating is usually carried out in the water during the daytime, the time is up to 3 ~ 5 hours, a fertilization can be multiple spawning, 3 ~ 5 days after mating to start spawning, the female snail at night climbed to the water surface 15 ~ 40 cm from the wall, stakes, aquatic plants on the stems and leaves to lay eggs. Eggs are round, pink, and about 2 millimeters in diameter. Egg particles adhere to each other into a block, each spawning a piece of 200 to 1,000 particles, spawning lasted 20 to 80 minutes. After the end of spawning, the female snail abdominal feet back, dropped into the water, after an interval of 3 to 5 days, the second spawning, a year can be spawned 20 to 40 times, the amount of egg production of 3 to 50,000 grains, fertilized eggs in the air incubation takes 10 to 15 days, the development of young snails rupture the membrane and out, dropped into the water.
