Bluegill

The bluegill is a fish local to this area, and is incredibly abundant. It is not native to Japan, but is apparently becoming incredibly abundant there too. According to the BBC

The fish were given to [the Japanese emporer] by the mayor of Chicago during a visit to the Chicago Aquarium nearly 50 years ago, when he was still crown prince.

They were taken back to Japan, and managed to escape into the wild, where they have now taken root.

One wonders how a bluegill plots escape...
