The humpback salmon, the Quasimodo of the sea, is loose in Danish waters, and the Asian hornet is munching on honeybees in Kerteminde. But there are other invasive species you should fear even more.
It’s a bit distinctive with a big bump on the forehead and up the back. But who cares about appearance when you’re getting something from your hands? The humpback salmon breeds in a much shorter time than normal Pacific salmon when it swims up the stream to lay eggs. Then it has a lot of young, which is why Russians and Norwegians have released them.
“That’s often the case with invasive species. They arise because enterprising people want access to more resources,” explains Peter Rask Møller, associate professor and curator at the Natural History Museum of Denmark.
