Fish Need to Move! Learning About Fish Migration - Colorado Pikeminnow

I was once very abundant in the Colorado River and its tributaries in states from Wyoming and Colorado to California, and I was an important food source for people. Today, many dams prevent me from migrating

to my spawning and feeding grounds. Other invasive non-native fish also have outcompeted me for food. Losing a place to live and lack of food has limited my ability to survive and reproduce. People are working together now to help recover me. They are constructing ways for me to swim around dams; restoring backwater habitat our young fish need to grow; working with dam owners to regulate water flows for my survival; and removing non-native fish that eat young pikeminnows and outcompete me for food.
