Freshwater lobster, commonly known as crayfish. In fact, it is not a lobster, but a kind of shrimp. There is also another name for the cockroach, which is a collective name for hundreds of freshwater shrimp species, named after its shape like a lobster. Almost all over the world. It contains three families (Crayfish family, orthopedic shrimp family and crawfish family), divided into dozens of genera, a total of more than 400 species. This number is somewhat staggering, due to the large number of species and the fact that some of the crayfish of the same genus are not very different. So here are just a few pictures of crayfish with distinctive characteristics to show.
First of all, let's take a look at the common crayfish on the domestic table ~ Ke's original shrimp. There are more than 400 species of freshwater lobsters in the world, but there are only four in China. This does not include this proto-shrimp. It is a species introduced to China by Japan and native to the United States.
↑ Protocellum crawfish
Also known as American crawfish, Louisiana crawfish, crawfish family ~ protostips genus. Its habitat extends from northern Mexico to the eastern United States in the Panhandle and was later introduced to Asia, Africa, Europe and other parts of the Americas. It multiplied rapidly, squeezing out the living space of the local shrimp species and becoming a famous invasive species.
Survive in warm freshwater waters, such as slow-flowing rivers, swamps, lakes and rice paddies, and grow fast. It can survive in a dry environment for 4 months or in low salinity water. So it is also a popular economic species. It accounts for more than 70% of the world's freshwater lobster production.
Catch small fish and shrimp and aquatic plants, and also eat animal carcasses. But it has a very bad habit, likes to drill holes (in fact, other crayfish species almost all have this habit), and the destructive power is strong. It can penetrate the fields and even the embankments, which is not conducive to flood control during the flood season. But in China it can hardly be destructive, because the rate of reproduction cannot keep up with the huge demand of the market.
In the early 1990s, the crayfish industry in Xuyi County, Jiangsu Province, began to develop. Xuyi's "thirteen spiced spicy crayfish" has become famous. Since the 2000s, the spicy crayfish (Ma Xiao'er) in Guijie Street in Beijing has gradually become a well-known snack and is popular with diners. Today, crayfish farming has become an important industry in many places, including Hubei, Anhui, Jiangsu, Hunan and other places.
