Yup. They need to be killed.
The fish I mean.
The Chinese have polluted their country to the extreme. They couldn't give a darn about ecology. They don't care about the misery they inflict on people, like they're gonna give half a darn about the plants and animals in their land. So you have to love how they import animals THEY like to eat to our country and just release them without any regard whatsoever what such a release will do to OUR habitats. It's like they feel like they own the joint already.
It would be like you sitting at home with your family watching TV when there's a knock at the door. You open the door and a bunch of Chinese walk in. They take measurements, bring in stuff, take your dog to the pound, and toss your stuff out the window while you stand there and sputter indignantly. Then they toss you and your family into the yard and close the door. Polluting our waterways with a voracious fish that gobbles up our native species without having asked anyone whether they could would be along the above lines!
