Crayfish, has always been called the crayfish of alien invasive species. Its ancestors first lived in America, and it has a domineering scientific name, which is actually salted lobster. There are many kinds of lobsters, including rock lobster, splendid lobster, corrugated lobster and honey lobster. And we also have many kinds, such as sweet crayfish, spicy crayfish, beer crayfish, stir-fried crayfish and so on. The blue-black crayfish is called Lagu, and some people call him Spicy Bone. Although these two look alike, they are not teammates. Unlike an alien invasive species like me, they are out-and-out northeast shrimps. This guy is a neat freak. I can live in polluted water, but I can't eat carrion, grass, mud and crayfish. So the team of crayfish is growing stronger and stronger, almost on the verge of extinction.

Many people think that foreigners don't eat crayfish, but in fact, at the beginning of 16 century, that is, 1523, Sweden was independent, newly founded and poor, so their boss began to encourage ordinary people to make a kind of crayfish that can be seen everywhere in their local area, and the result was really delicious. Later, they also held a crayfish festival. Later, crayfish became popular in Europe, and the United States became the first country to breed crayfish.

From 65438 to 0927, crayfish were introduced to Japan to feed bullfrogs. Life is so boring, but we haven't given up on ourselves. We continue to strive to improve ourselves. The Japanese and Korean teams are getting stronger and stronger again. In this way, several years later, crayfish finally came to Nanjing, China. It doesn't look delicious, but I believe that in such a country with a long history of food, any elegant ingredients will not be buried forever.

1993, the people of Jiangsu suddenly realized. They invented a way to eat thirteen-fragrant crayfish. We finally became an instant hit and became the most popular food stall among online celebrities. But the so-called red shrimp is not much, the domestic sewage of crayfish is too dirty, the heavy metals of crayfish exceed the standard, and crayfish only eat garbage. In fact, it is just more adaptable to the environment than ordinary animals in water, because our body contains astaxanthin, and the content of astaxanthin is directly proportional to the severity of the surrounding environment, which can help us enhance our viability. Regarding the problem of heavy metals, crayfish exposed to heavy metals are indeed rich in some harmful elements, but most of the heavy metals in their bodies are distributed in their heads, that is, their internal organs and shells. These parts do have the risk of heavy metals exceeding the standard, but the heavy metals in the meat meet the safety standards, so don't eat your head.
