Speaking of “net red crayfish”, whether it is a high-end hotel, or small restaurants, or stalls, crayfish is no disadvantage, is simply the iconic summer food. Crayfish, also known as Docker’s crayfish, native to South America, probably introduced by Japan in 1927 or so, during World War II and from Japan into China. Now mainly distributed in the middle and lower reaches of the Yangtze River. Crayfish nutritious, fluffy meat, excellent taste, its protein content more than most fish and shrimp, and the fat content is very low and mostly unsaturated fatty acids, easily absorbed by the body, can prevent fat accumulation in the body, it is simply the welfare of the fat ah! Crayfish also contains astaxanthin, anti-aging, antioxidant, prevention of cardiovascular disease, improve immunity, for the elderly is also a good choice. Nevertheless, I found that many people have some misunderstandings about it, some rumors are always shrouded, so really can not stand to see, for the crayfish is a positive name! 1, crawfish is very dirty? Before a lot of articles have said that crawfish live in a very dirty environment and so on. Have not seen the living environment of crayfish, see these articles are easy to believe. In fact, the crayfish on the water quality requirements are still very high, although the crayfish tenacious, but does not mean that they like to live in dirty water, it has been proved that the crayfish in the dirty water will slowly die, that they like dirty water is no basis. 2, it is the Japanese genetic modification brought over to clean up the body? Crayfish in many rumors in this is the most fire, clicks super-high, in 1929 during World War II crayfish flowed into Nanjing by Japan, which is the source of the body of crayfish elimination, when the Japanese army just landed in Nanjing, and the Anti-Japanese War has not yet erupted, Nanjing is not a war zone in the day, so there is no dealing with the dead body of the matter, and in the seventies of the last century before the beginning of the study of DNA recombination technology, from time to time! Look at the Japanese army to carry out genetic modification is impossible, it has nothing to do with the Japanese invasion of China. China is a major exporter of crayfish, you think can be sold abroad, the quality is certainly guaranteed! As the saying goes, rumor stops at the wise man, I hope that in the future you first understand the truth, so as not to cause inconvenience to those around you!
