Guangdong is a place with very good hydrothermal conditions, and the subtropical climate here is very suitable for the survival of organisms. As an important window of foreign trade, Guangdong has inevitably become the first stop for the invasion of many alien species. Invasive alien species are nothing new. Compared with the beloved crayfish, most invasive species are not likable, such as water hyacinth, violet chamomile and so on.
In addition to plants, there are large snails from Africa, crocodile eels from the Americas, alligator eels are a huge fish, according to the Guangdong people who eat everything, should not let go of this big fish, but so far, the crocodile eel is still the most helpless American giant fish in Guangdong. Why is this happening? The alligator eel is a primitive species, a living fossil in fish, which was born as early as the Cretaceous period.
The body of this big fish is covered with hard scales, and its mouth is full of fangs. The alligator eel can grow to more than 3 meters long and weigh nearly 100 pounds, which is a very famous ferocious freshwater fish, almost the same as the Yangtze River white sturgeon is a hierarchical existence. Crocodile eels have natural predators in the Americas, such as alligators, but no natural enemies in Guangdong. It can lay hundreds of thousands of eggs at a time, and in the absence of natural enemies, the speed of flooding in the wild will be very fast.
In the early years, people still liked the alligator eel because of its beautiful appearance, but in the wild environment, Guangdong's native fish resources were seriously threatened. The best way to deal with alligator eels is to develop it into a delicacy. But it's difficult. Crocodile eels are not poisonous in themselves, but produce toxins during spawning, and the meat of crocodile eels themselves is OK, making it a popular delicacy in the Americas. But in the eyes of Guangdong chefs, crocodile eel is really not a good ingredient.
Crocodile eels have a poor meat texture, hard scales on the outside, and even use an axe to split when processing. Once the alligator eel grows up, it is difficult for one or two people to catch it, and several people can complete the capture, and the cost of capture is too large. The problem of crocodile eels, said big is not big, said small is not small, depends on whether the cantonese cooks have creativity.
