    Walleye and yellow perch resource use in large lakes invaded by spiny water fleas and zebra mussels

    Walleye (Sander vitreus; WAE) and yellow perch (Perca flavescens; YEP; collectively percids) are freshwater fishes threatened by multiple stressors, including aquatic invasive species. Zebra mussels (Dreissena po...
