On November 29, in the central pool of Hedong Park in Liuzhou City, the staff caught a strangely fierce big fish! Look it up on the Internet, good guy, it's a red-tailed catfish, which belongs to an invasive alien species!
This "strange fish" is about 0.6 meters long, 0.2 meters wide on the head, and weighs about 4 kilograms. Its body is wide and flat, with a few whiskers growing around its mouth, and its orange-red tail fins are particularly conspicuous.
According to the staff, as early as the beginning of November, when the park held a flower exhibition, someone found the trace of this strange fish. It swims very fast, eating the ornamental koi in the pool, "the koi that weighs heavily, almost one bite at a time."
According to its appearance characteristics, the staff found out that it was a red-tailed catfish. This fish itself is also an ornamental fish, and there are some names called "fortune cats".
The red-tailed catfish nickname is cute, but fierce! It is a carnivorous fish native to the Amazon Basin of South America, which is very preying and eats a large amount, and after the formation of an invasion, it will have a destructive impact on the ecosystem.
"This fish appears in the park water body and is 100% artificially released." The staff said that in the pools and artificial lakes of Hedong Park, in recent years, there have been highly destructive invasive alien species such as crocodile eels, seven-star knifefish, silver arowana, and Brazilian turtles.
The koi in the pond are eaten by these "foreign killers" and have to replenish the fry every year.
