There are already countless invasive species in China, causing great harm to China's natural ecology and China's original animals and plants. So if you're not an animal and plant professional, don't release it blindly!
Today I'm going to introduce a few of the more vulnerable invasive species of chickens.
Alligator eel
First of all, introduce the crocodile eel that has been on the hot search these days, the alligator eel is a freshwater giant carnivorous fish endemic to North America, which is now only found in the east of North America, Central America and Cuba, and its biological classification belongs to the order Finches - Finches - Large Finches. The alligator eel is generally 1.2-1.8 meters long and weighs 45-72 kg, which is a relatively large freshwater fish, but compared with the Chinese sturgeon, the giant catfish, and the European catfish, it is a younger brother! The alligator eel's mouth is named after the crocodile's mouth that resembles a fang-filled crocodile.
In China, it is mainly used as an ornamental fish, of course, many hypocrites who do not understand ecology will release it, which will cause certain ecological harm, but in China, its ecological destructive power is actually not so large, that is because the crocodile eel is a freshwater fish in tropical waters, and the water temperature required for its survival needs to be 12-15 ° C. So recently in Henan in order to catch a crocodile eel to drain the whole lake, in fact, is very stupid, very unnecessary, because this fish can not live for three months, Henan winter can be very cold, it will definitely be frozen to death. Alligator eels are harsh on their living conditions, making it difficult for them to adapt to China's freshwater waters, so the ecological harm to China is far less than that of other invasive species! It's a weak chicken!
Piranhas
The piranhas we are familiar with mainly refer to the Members of the order Salvia of the Mulberry sawfish and the N.S. The Nasturtium gluteal carp is the kind we often see in movies, the Nasturtium gluteal carp is also known as the red-bellied piranha or red-bellied goby, mainly distributed in the gentle flow of the Amazon River Basin in South America. Its body length is generally between 30-50 cm, it belongs to the large lipid carp, and is also introduced in China as an ornamental fish or weeping fish. The Samson sawfish, also known as the Red Diamond Piranha, is found in the Pacaya and Ucayali rivers of Peru, and has a fierce temperament! After all, most ordinary people do not distinguish the difference between various piranhas, and they are also introduced as ornamental fish or weeping fishing.

Piranhas are actually in their hometown, which is actually the middle and lower level of the food chain, which is very weak. Amazon pufferfish, arapaima, giant otters, electric eels, and even the white caimans in crocodiles are also natural enemies of piranhas, and they are really weak chickens.
Of course, there are also many ignorant hypocrites to release them, and these piranhas are also very weak chickens, because they are also fish in tropical freshwater waters, and the water temperature requirement for survival is 24 ° C ~ 30 ° C, so you release them, many of them still can't survive the winter in most parts of China. But indiscriminate release will still cause some harm to China's waters!
You think of the "weak chicken" crayfish
Next, a rumor, a most undignified invasive species blown up by online marketing trumpets - crayfish!
Crayfish, also known as protocrayfish crawfish, are also native species in North America.
Crayfish are highly adaptable and can grow and develop normally when the water temperature is 10-30 °C. It can also withstand high temperature and cold, can withstand high temperatures above 40 °C, and can also overwinter safely in the case of temperatures below -14 °C, and its growth and reproduction ability is also super. As a result, serious ecological invasions have been created in several countries. The mainland is also, in addition to the mainland farming, a large number of crayfish live in the wild, has caused great harm to the ecology of various places, they not only prey on the native aquatic animals of the mainland, but also nibble on crops, destroy the embankment, and squeeze the living space of the native shrimp and crabs on the mainland. Don't really think that we Chinese can be destroyed by eating them, wild crayfish contain a lot of parasites and germs, can not be eaten at will! It's all marketing!
So the best way to encounter all kinds of invasive species in the wild is to physically overdo it, and don't think about eating them, unless you want to experience the taste of parasites and germs!
