Northern Pike

Northern pike (Esox lucius) are an important component of the nearshore fish community of Green Bay.  However, compared to many other species, we know relatively little about their reproductive ecology, population strength, and habitat utilization.  During the spring northern pike travel through local streams and ditches to find suitable spawning habitat, which consists of shallow wetlands with drowned vegetation.  70 percent these wetlands no longer exist due to changes in land use practices like agriculture and urban development.  There has been a concerted effort by Brown County, WIDNR, and the USFWS to restore these wetland over the last 20 years.  Our lab has worked to identify the environmental cues northern pike use to choose spawning wetlands and what conditions are necessary for successful recruitment.
