Fish Trails

It’s not easy being a fish.

Fish migrate through rivers to find food, seek shelter, and spawn. Along the way they must dodge predators, navigate obstacles, and overcome a host of challenges to reach their goal. 

Do you have what it takes to navigate Fishcadia River as a fish? Have fun and enjoy the adventure!

About the game

Fish Trails was informed by experts in fish passage and hydropower research. It is intended to be educational and to represent events that can happen to fish in the real world, but it is a work of fiction and may not be all-encompassing. This game was developed by Pacific Northwest National Laboratory (PNNL) and sponsored by the Department of Energy Water Power Technologies Office.
