What is a snail and what does a snail look like

Fushou snail, also known as apple snail, is known as the "French snail". Native to the Amazon River basin in South America, it is a large freshwater edible snail. In 1982, it was introduced into the mainland of China for trial breeding and promotion, and has basically spread all over the country.

Fushou snail has the characteristics of strong adaptability, fast growth rate, easy multiplication and easy maintenance; Its flesh is golden in color, crisp and delicious, with high nutritional value, and at the same time has health care functions.

The requirements for water quality are not high, the pH value is about 7, the dissolved oxygen is more than 3mg l, and the total hardness is 6-13 degrees Celsius in the freshwater waters can be cultivated, and its survival water temperature is 0 degrees Celsius-38 degrees Celsius, and the most suitable water temperature for growth and reproduction is 25 degrees Celsius-30 degrees Celsius. Fushou snails are omnivorous snails, but they are mainly plant-based feeds. The staple food is a variety of aquatic plants, terrestrial grasses, melons, fruits and vegetables, such as various duckweed, water peanuts, water hyacinths, green vegetables, grasses, melon skins, fruits, etc.

They also eat artificially fed bran bran, cake feed and scraps, etc., and also ingest some residue bait, humus, and zooplankton when food is scarce.

Fushou snail has high nutritional value and can promote the rapid growth of soft-shelled turtles. According to the inspection of the Institute of Health of the Chinese Academy of Medical Sciences, Fushou snail is a high-protein, low-fat nutritious food, and the protein content of fresh snail meat is high, which is equivalent to eggs and fish; In addition, it is also rich in calcium, phosphorus, iron and vitamins A, B and C, etc., which is an ideal animal feed for soft-shelled turtles, and can also be fed to ducks and fish.

Liu Xiaoquan, a researcher at the Parasite Research Laboratory of Guangxi Medical University, believes that Fushou snails can be eaten, but they must be cooked before eating. Whether it is snails, chickens, ducks, or fish, these fresh foods are more or less parasitic, and raw food can easily cause parasites to enter the human body, and parasites swim in the human body, which is likely to cause human tissue lesions.

What the hell is a "Fushou snail"? Single-handedly, more than 80 people were infected with the brain.

<> Fushou snail is a mollusk belonging to the family Bottle Snail.

The snail is very similar to the field snail in appearance, the snail shell is mostly externally rotated, the whole body is brown, and the head has two antennae, of which the antennae at the front end are shorter, and the antennae at the back end are relatively longer, and at the same time, there is a pair of eyes distributed at the top of the longer antennae.

Characteristics of Fushou snailsThe snail has a strong ability to adapt to the environment and reproduces quickly, so it quickly spreads in rivers, lakes and fields; It eats a large amount of food and has a wide variety of foods, which can destroy food crops.

Vegetables and aquaponics.

The growth of crops. The characteristics of the snail are easy to distinguish, the color is mostly blue-yellow and yellowish, the tail is short, the screw mouth is large, and the shell is generally brittle and can be crushed.

And the head of the snail has two pairs of antennae, the anterior antennae are shorter, the posterior antennae are longer, and the base each has an eye, and the snail is suitable for growing in an environment with fresh water quality, likes sweet food, and mainly feeds on duckweed, vegetables, melons and fruits.

The appearance of the snail shell is similar to that of the snail.

It has a spiral shell, the color varies with the environment and the age of the snail, it is shiny and has several fine longitudinal lines, and the head and gastropods are protruding when crawling.

The egg masses are oval, different sizes, the eggs are arranged neatly, the egg layer is not easy to fall off, bright red, the small egg masses are only dozens of grains, and the large egg masses can reach more than 1,000 grains.

Habits. Fushou snail has a wide range of food, is an omnivorous snail based on plant bait, mainly eats duckweed, vegetables, melons and fruits, etc., especially likes to eat sweet food, but also loves to eat animal carrion in the water. When there is no more food, they eat tiny substances floating on the surface of the water (the body turns upside down and feeds on the object with foot movement).

Although the snail is an aquatic mollusc species, it can be buried in moist mud for 6-8 months during the dry season. In the event of a flash flood or irrigation, they can become active again. The respirators of adult snails can reach up to 5-10 cm long or longer.

The meat of Fushou snail is delicate and delicious, rich in protein, carotene, vitamins and minerals.

The appearance of the shell of the snail is similar to that of the snail, but the individual is larger. It has a spiral-shaped snail shell, the color varies with the environment and the age of the snail, and it is shiny and has several fine longitudinal lines.
