What should I pay attention to when eating shrimp? How did crayfish become the worst invasive species?

To eat shrimp, pay attention to the following aspects.

1. Wash well.

Many times it seems simple, but it is really troublesome to wash crayfish and want to clean it, if it is a pound or two pounds is not enjoyable at all, many times you have to eat a lot, it means that you have to wash a lot, and you have to wash it many times. I often see the back of some people washing shrimp, looking at the repetition of simple operations, in fact, it is an afternoon or a day to wash, it is very painful to eat, it is very painful when washing, this is an indisputable fact, and every time I find that the water of the shrimp is so dirty, if you don't wash it clean, the stomach will be uncomfortable after eating, and you will get sick if you eat too much, which shows that washing shrimp is really important, and you must wash until the water is clear. Therefore, it is best to eat lobster at home, and the outside restaurant may not be clean, which will make people feel very uneasy.

Second, pull the shrimp line.

Many people eat lobster without making shrimp line will have a lot of harm, shrimp line must be removed, many people are not in good health, if you do not pull out the shrimp line will cause disease, a lot of physical discomfort, so pay attention to the shrimp line, not only clean, the shrimp line to remove is a very critical step.

Crayfish is not Chinese, as an alien species, not only did it not end well, but became a delicacy in the mouth of the Chinese, so it is still quite miserable, almost eaten up, this is its end, I thought that the reproduction was fast, and the result could not withstand the speed of the Chinese eating, so the crayfish is really not so easy, now there are a lot of farmed lobsters, in the end it still did not escape the Chinese. Various ways to eat are also endless, we don't seem to take into account the life and death of lobsters, take it out is a meal, and then cut, really embarrassed lobster, so it seems that it is the most miserable invasive species It is not too much, it is really too Chinese to eat. It's so delicious, it's delicious.

Be sure to wash the shrimp, it is best to be able to blanch the water first to remove the fish, and when eating, you should remove the shrimp line. Because crayfish have a very rich taste and are loved by people, they are vigorously caught in the wild.

To remove the shrimp head and shrimp line, to buy fresh live shrimp, not dead shrimp, but also to cook the shrimp thoroughly to prevent allergies. Crayfish can be made spicy, can be made into garlic, very popular with people, in the end did not succeed in letting crayfish invade.

When we eat shrimp, we must scrub it clean, and cook it to prevent parasites, mainly because crayfish are delicious and people love to eat them very much, so it is called the most invasive species.

Yes, crayfish are invasive alien species. Crayfish is also known as crayfish, red crayfish and freshwater crayfish, native to the United States, the earliest Japanese introduced more than 20 crayfish from the United States, used to do experiments, found that crayfish are rich in protein, very suitable for breeding bullfrog protein feed, in the 30s of the 20th century, China was introduced from Japan, and gradually became an important economic breeding species in China.

Related information: Crayfish has a wide range of adaptability, has a wide range of suitable growth temperatures, and can grow and develop normally when the water temperature is 10 to 30 degrees Celsius. It can also withstand high temperatures and severe cold, can withstand high temperatures above 40 degrees Celsius, and can also survive the winter safely when the temperature is below minus 14 degrees Celsius.

Crayfish grow rapidly, in the case of suitable temperature and sufficient bait, after more than 2 months of breeding, you can reach sexual maturity and reach the specifications of commercial shrimp, generally male shrimp grow faster than female shrimp, and the size of commercial shrimp is larger than that of female shrimp. Like many crustaceans, crayfish grow with molting, which is often sought out for shelter, such as in aquatic weeds or under plant leaves.

1. Crayfish is an invasive species. China was introduced from Japan in the 30s and 40s of the 20th century, and Japan introduced it from the United States in an earlier period, mainly for food and pets. Crayfish are often polycultured in fields of crops such as rice.

There is no need for artificial incubation, and once the pond is stocked with seeds, it is self-sustaining, and after harvesting, there is no need to restock. Escaped specimens survive by digging holes in the levees. They can survive in temporary water bodies and have a wide range of feeders, establishing populations very quickly and spreading easily.

It is extremely threatening to local fish, crustaceans and aquatic plants, and disrupts the local food chain; Direct catastrophic damage to crops (especially aquatic and semi-aquatic crops such as rice) and natural vegetation due to its feeding on the root system; Hole construction causes the loss of irrigation water and the destruction of fields; Due to the mixed feeding habits of crayfish, it has a certain degree of influence on the flowering of fish fry and the cultivation of 1st year old fish fingerlings, and harms the artificially bred juvenile mussels.

2. Due to the strong adaptability, strong stress resistance, wide feeding habits, and fast population proliferation, crayfish often cut crops, especially rice crops, and may compete with local freshwater crayfish species.

Strictly speaking, there were crayfish in ancient China, because there are actually four original authentic crayfish in China, namely Northeast black crayfish, Nanjing crayfish, Shi's crayfish and North Korean black crayfish.

However, the crayfish currently eaten in China is not the above four kinds of stool ants, but the crayfish native to the United States, which is a real invasive alien species, so from this point of view, there are no crayfish in ancient China.

The crayfish I am talking about now mainly refers to a kind of freshwater shrimp that is currently consumed in large quantities in China, which is actually crayfish crayfish. This kind of freshwater crayfish is a veritable alien species, and it was not introduced into our country until the 30s of the 20th century. The method of eating crayfish and scientific research did not begin until the 60s of the 20th century.

In 1983, Mr. Dai Aiyun, Institute of Zoology, Chinese Academy of Sciences, first advocated the development and utilization of freshwater crayfish as an aquatic resource. And this is the crayfish that we currently eat a lot of.

Hello, crayfish is an invasive alien species. It is native to the Americas and was later introduced as an aquaculture species in places such as China. Crayfish has gradually expanded in China's farming and consumption markets, and has become a popular bulk delicacy.

However, crayfish also brought some problems with the transport of socks. They are highly reproductive, which has a certain impact on the aquatic ecological environment, and may even pose a threat to local aquatic life. Therefore, crayfish is considered an invasive alien species.

Invasive alien species refer to non-native species that have been introduced as a result of human activities and that may cause damage to local ecosystems. The invasion of crayfish has also attracted people's attention to ecological and environmental protection. In order to reduce the impact of crayfish on the ecological environment, some measures have been taken, such as restricting the cultivation and sale of crayfish, and strengthening the supervision of side excavation.

Hello, not crayfish is not invasive alien species. Although there are some legends about the invasion of small shrimp, they have been recognized as an invasive alien species worldwide. In China, although the small dragon stool shrimp has become a special snack, it did not originate in China, but was introduced to China after the improvement of the craftsmanship of the Japanese.

In addition, crayfish is also included in the list of invasive alien species in Yunnan Province, but this is only the first provincial list of invasive alien species in China.
