| Impact Description | White perch (Morone americana) are hypothesized to compete with native yellow perch for zooplankton. The growth rates of yellow perch have declined since the invasion of white perch in Lake Erie, especially in the western basin. The two species have considerable diet overlap and it was found that white perch consumed 27 percent more food than yellow perch in one sample. |
