With the development of globalization, there are more and more exchanges between countries in the world, which also leads to a big problem, that is, species invasions have become more frequent, invasive species can follow this human means of transport, to more and more places, so now there are more and more global invasive species, but are alien species necessarily bad? This is not necessarily true, now many countries will introduce some species from other countries, for breeding, or ornamental, environmental protection, etc., although sometimes because of the introduction of species and cause species flooding, such as the Original Introduction of Asian Carp in the United States is to purify water quality. However, there are also cases where introduced species have brought good results, such as mosquito-eating fish, which have been introduced by various countries because of their mosquito-feeding characteristics, and have become a very popular introduced species.
And China has also introduced an Australian freshwater lobster, this lobster and we usually eat crayfish is larger, the taste is not bad, will it replace the position of crayfish in China's foodies? This lobster is called red crawfish, the shrimp body color brown-green, because its outer tip of the crawfish has a membranous bright red band, beautiful and good-looking, so it is also known as the red crawfish, its adaptability is strong, wide eating habits, fast growth, delicious taste, and tender meat, so it is also very popular in China.
Red crawfish was introduced to China in 1992, successfully tried to breed in Guangdong and Hubei provinces, and then Fujian, Beijing, Hunan, Jiangsu and other places began to breed this lobster, red crawfish a weight is generally between 20-100 grams, the large can reach 500-600 grams. Its viability is very strong, can adapt to a lot of harsh environments, in rivers, reservoirs, ponds can live, and can eat a lot of things, mainly to aid the food of organic detritus, algae, filamentous algae, aquatic plant roots, leaves and fragments, and very fond of eating juice-rich green food, water hyacinth is also one of its favorite foods.
Because the red crawfish is easy to raise, and the characteristics of more meat, now it is a very common aquaculture, in Europe, Japan and China is welcomed in the market, red crawfish meat is delicious, and large, delicious meat, compared to crayfish, its taste is better, and the meat is more, but the red crawfish has been more than 20 years, and now the market is still the world of crayfish, why is this? Mainly because the price of red crawfish is very expensive, it is one of the most expensive freshwater economic shrimp in the world, so even if its advantages are very many, crayfish is still the "king" in the night market.
Although the red crawfish has not replaced the position of crayfish, it is still a very popular food in China, and many families will buy red crawfish during the New Year's Festival or when entertaining guests, so although the price of red crawfish is somewhat expensive, it can still occupy a place in China's aquatic market. Red crawfish is a positive example of an introduced species in China, bringing economic benefits to China and posing no threat to the environment.
