Impact of the Round Goby on Yellow Perch Recruitment

Lake Michigan's yellow perch fishery has yet to rebound from a   population crash in the early 199 s that closed the commercial   fishery and severely restricted the sport harvest. Yellow perch   prefer to spawn in rocky areas, such as the western side of Lake   Michigan, which also happens to be prime habitat for the round goby,   an invasive species that first appeared in the lake in the early   199 s and aggressively feeds on the eggs of other fish.    This new project will examine the interaction between these species   at multiple sites in the lake in an attempt to determine the round   goby's impact on yellow perch recruitment. This AIS project also   addresses a Wisconsin Sea Grant Fisheries Theme priority of   identifying key factors preventing the yellow perch fishery's   recovery in Lake Michigan.    (round goby); (round gobies); (yellow perch); (AIS); (aquatic   invasive species); (ANS); (aquatic nuisance species); (Wisconsin);   (Lake Michigan); (Neogobius melanostomus); (Perca flavescens)
