There is a "giant green shrimp" in the Yangtze River, which weighs a kilo and tastes delicious. Will it replace crayfish?
After a long period of confrontation and adaptation, the ecological environment in various regions has reached a relatively balanced state, and the arrival of alien species often breaks this balance, thus forming species invasion events. Due to the progress of modern transportation technology and frequent trade, it has become a common thing that exotic species move with human means of transportation.

China is a vast country with different climatic conditions and natural environment, so it is often invaded by species, especially in southern China. Because of the good climatic conditions, it is often invaded by alien species, such as crayfish, which is listed as an alien invasive animal in Yunnan Province. In the Yangtze River basin of China, another alien invasive species has appeared in recent years.

"Giant blue shrimp" appeared in the Yangtze River basin, weighing more than 1 kg.

This species found in the Yangtze River area is called swamp shrimp, which is a kind of shrimp native to Southeast Asia. It is a kind of "giant shrimp", weighing over 1 kg and having a body length of over 40 cm.

This kind of shrimp can often be seen in the Yangtze River valley in China because the swamp shrimp culture has been introduced to Guangdong, China. This kind of shrimp is very suitable for breeding, with strong reproductive ability, strong viability and wide feeding habits.

However, because many green shrimps will "escape" from farms and become wild species in the process of breeding, the Yangtze River basin is a common basin for green shrimps. Shrimp has strong viability, and it is also very easy to cause species invasion. Even some green shrimps have been flooded in their country of origin, but in China, green shrimps have not been flooded.

Marsh blue shrimp is delicious, will it replace crayfish?

At present, in the southern part of China, cultured freshwater shrimps are still widespread, but wild freshwater shrimps can't be flooded. Generally speaking, as long as a place is flooded, local people will go fishing and catching shrimps at the first time, which will soon solve the problem of a large number of shrimps. Therefore, in daily life, if you want to buy green shrimp, you still need to buy it in the market, which is difficult to find in the wild.

Shrimp tastes good, the meat is delicious and delicate, and there is no fishy smell. And compared with crayfish, green shrimp has more meat. Although crayfish is delicious, it has more shells and less meat, which many people don't like, and green shrimp can make up for this defect, so many people think that green shrimp is the best substitute for crayfish.

However, it is still difficult for green shrimp to replace crayfish. The main reason is the price. Shrimp is more expensive than crayfish. Moreover, at present, the cultivation of freshwater shrimp in China is not enough, and it is not flooded in the wild, so it is difficult to provide enough shrimp to the market. For example, in Viet Nam, the consumption of green shrimp is very common because of the flood of green shrimp, but crayfish is difficult to be replaced in China in a short time.
