Invasive species slow walleye growth, study says, meaning fewer survive winters

Young walleye growth rates decline by 12 to 14% in Minnesota lakes invaded by zebra mussels and spiny water fleas, researchers concluded in a study published recently.

Led by University of Minnesota Assistant Prof. Gretchen Hansen, it becomes one of the few studies to show impacts of aquatic invasive species on high-level fish such as walleye. A summary of the study in the journal Biological Invasions said slower growth makes it more difficult for baby walleyes to survive.
