Alberta Fish and Wildlife has been experimenting with cross breeding fish.
The took a coho salmon that's noted for it's good eating and crossed it with a walleye, also noted for it's good eating. They named this fish the Cowal.
Then F&W decided they wanted to cross the cowal with a good fighting fish so they crossbred the cowal with a muskie.
Unfortunately, F&W ended up with a "Cowalski". Darn fish doesn't know how to swim.
