CATDOLL : CATDOLL: The growth cycle of river snails

1. The growth cycle of river snails

river snail

It refers to the mollusks of the family Snails, belonging to the class Gastropoda, subclass Prosobranchia, family Snails. Snails are distributed in most areas of China. Snails have high requirements for water quality and low yield. They can be caught in summer and autumn.

When the water temperature rises to 15℃ in late spring and early summer, the snails crawl out of their hibernating holes and feed and grow at the bottom of the water. They start to reproduce in April, and July to August is the peak season for snail reproduction. Female snails aged 1 to 2 years can produce 20 to 30 offspring, and female snails aged 4 years and above can produce 40 to 50 offspring. The offspring grow rapidly after birth and can develop into sexual maturity in one year. The offspring season is from April to September every year.

Snails are mollusks that are easy to grow and suitable for ponds, rivers, ditches and paddy fields. Snails have the effect of clearing away heat and reducing internal heat, and are a delicious snack for people in midsummer. The yield per mu can reach about 2,000 kilograms, with an output value of 4,000 yuan. The high-yield snail breeding technology is introduced as follows:

1. Choose a site. Snails have strong vitality and disease resistance. They can be raised in ditches, paddy fields, and shallow ponds with running water sources. Generally, ponds are built for breeding. The snail pond is generally 2-3 meters wide and 10-15 meters long. The pond is surrounded by ridges with a height of 0.7 meters. Fences are installed around the pond to prevent the snails from escaping. The bottom of the pond is covered with 20 cm thick fertile mud, and new water is injected. Water lilies, small gourds, red and green duckweed, etc. are raised on the water surface to provide food for the snails. Small bamboo poles or wooden strips are inserted in the pond for the snails to inhabit and lay eggs.

2. Stocking of seedlings. Select seed snails or young snails and stock them in the pond. After the pond is built, generally choose to stock and breed them from April to November. June to September every year is the season for snails to lay eggs in large quantities. You can pick them up in rice fields and ditches, or buy them in the market. The characteristics of female snails are: light brown in color, thin shells, round bodies, and blunt tails. Select 15-20 grams of female snails and stock them in the pond. Generally, 10 female snails can be stocked per square meter. Young snails are selected as seedlings. They are stocked in a ratio of 2:1 between male and female. Female snails are larger, with round bodies and concave shells; male snails are slightly smaller, with longer bodies and convex shells. Young snails can be caught and marketed after about one year of breeding.

3. Feeding and management. Snails have abundant food, and microorganisms, organic matter, and young stems and leaves of aquatic plants in the water are their main food. During the peak growth season of young snails, rice bran, wheat bran, tofu dregs, cooked sweet potatoes, small insects, small fish and shrimp, and animal offal should be added between April and November each year. You can also feed compound feed. The feeding time is once every 8-9 o'clock every day. Large baits should be chopped before feeding. The daily feeding amount is about 1.5% of the snail body. New water should be replaced regularly to keep the water quality fresh, and the water should be changed about once every 10 days. When the water temperature is above 30℃, new water should be injected frequently to deepen the water level. It is better to keep the water depth at 30 cm. In winter, the water level should be lowered during the day to increase the light. Deepen the water level at night. In order to keep warm, some pig manure and manure should be applied to increase the temperature and fertilize the water quality. Snails are sensitive to pesticides and industrial wastewater. They should be avoided, and ducks should also be noted.

4. Fishing and marketing. After one year of breeding, the snails that weigh more than 15 grams can be fished and marketed. The fishing method can be dry pond fishing or shallow water fishing. At the same time, some female snails should be kept to prepare for breeding of young snails next year.

5. Winter management. When the water temperature drops to 8-9℃, the snails begin to hibernate. During hibernation, the snails drill into a hole, leaving a small hole on the soil surface, and bubbles come out from time to time. At this time, they do not eat or move. The water depth should be kept at 10-15 cm, and the water should be changed every 4-5 days to increase the oxygen content and allow the snails to safely overwinter.

2. What kind of leaves do people like to put in stir-fried snails or other dishes in Lingshan County?

1. The leaves used for stir-frying snails should be fake X.

2. The written language of that leaf is called “假X”. “X” is pronounced with the third tone.

Other names: false N, clam N ("Lingnan Collection of Medicinal Herbs"), false Trichosanthes ("Nanning City Medicinal Records")

3. Pictures

4. Some places also add perilla or osmanthus leaves when stir-frying snails.

Hello!

The written language of that leaf is called "假X". "X"JU is pronounced with the third tone.

Other names: false N, clam N ("Lingnan Collection of Medicinal Herbs"), false Trichosanthes ("Nanning City Medicinal Records")

You said that the local dialect is "ge lao", try to read it with the above: 假N、哈N、假蒌, don't they look a bit similar? ! Because of different dialects, our pronunciations may be different.

When we stir-fried snails, we also added another kind of leaf called "perilla". Right!

Hope it helps!

I am from Lingshan too! (*^__^*) Hehehe!

Guangxi people like to add some ingredients when stir-frying snails, among which Pseudo-Trichosanthes is an indispensable ingredient. Pseudo-Trichosanthes is warm in nature, while snails are cool in nature. If you eat too much snails, it will be too cold and you will have a stomachache. Putting them together with Pseudo-Trichosanthes will just neutralize the warm and cool natures.

That kind of leaf is called bay leaf, which is a kind of seasoning, used for seasoning, haha

It’s perilla, which can remove the fishy smell.

We can add some when we cook fish or shrimp.

You can refer to the instructions on Baidu Encyclopedia.

3. I have a two-acre fish pond and want to raise snails instead. Is it better than raising fish? Is there a future for raising snails?

Farming is risky, so be cautious when entering the industry

In summer, all kinds of barbecue stalls emerge, and we all know that more and more people like to eat snails and think it is a very delicious food, so many people are not averse to such food.

Well, what we are going to talk to you today is what we should pay attention to when raising snails, otherwise, we will cause certain losses when raising them.

First of all, when we are breeding, we need to pay attention to the time control when releasing snails. Generally speaking, in March every year, when the water temperature reaches 15 degrees, we can put the snail seedlings in. In this way, it will grow for about a year, and the snails will basically grow to the size sold on the market. Moreover, the snails will still produce a lot of small snails, so we will have a harvest next year, and even after raising them for a few years, there will still be some.

Another issue we need to pay attention to during the breeding process is the issue of food. Snails prefer to stay in places with more aquatic plants. They will eat some microorganisms or plants in the water. So when we raise them, we must pay attention to choosing a pond that has more microorganisms.

If it is artificially bred, we can plant some aquatic plants in the pond, then the aquatic plants will directly provide nutrition for the snails, which is very good. This includes some of our leftovers, such as rice bran, which are very good food for snails. But when we put them in, we must not put too much. If we put too much, it will cause certain damage to the pond, which will cause some losses to us.

The most suitable temperature for field snails is probably between 20 and 28 degrees. Under such conditions, their growth and development are very rapid. If the water temperature is very low, the field snails will enter a dormant state and will not grow. It is a very bad situation for breeders when animals enter a dormant state. Therefore, the water temperature must be kept in an environment suitable for their growth. In this way, their later yield will be very high.

In addition, during the breeding process, snails can also get sick. If we find dead snails, we can just pull them ashore. If there are too many dead snails, we must check the cause, whether it is a water quality problem or some other problem. If you have any questions during the breeding process, be sure to ask the professionals who breed snails.

According to my understanding, snails are more popular in the south, because people in Guangdong and Guangxi will fry snails to drink at night when they go to food stalls, hot pot restaurants and restaurants. However, the price of snails sold in the market is not as high as 10 yuan per catty as you said. I am in Dongguan, and when I go to the market to buy vegetables, I often buy one or two catties of snails to fry. Generally speaking, small snails are about 5 yuan per catty, and larger ones are about 8 yuan. However, the breeding technology and cost investment of snails should not be high, so there is still a lot of profit space and development prospects.
