Growth and survival of nearshore fishes in Lake Michigan

Illinois Department of Natural resources Grant/Contract No: F-138INHS Technical Report Prepared for Illinois Department of Natural resource

Growth and survival rate of nearshore fishes in Lake Michigan, 2014

Research described in this report focuses on Illinois waters of Lake Michigan and provides essential information for the Illinois Department of Natural Resources (IDNR) to better understand factors contributing to nearshore fish community assemblages in a spatial and habitat related context. Information presented herein expands limited data and directly aids fisheries management efforts. This report describes results obtained during 2014field season and marks the sixthyear of major changes to the project, which included changing sampling locations, expanding sampling sites to include different habitat types, and expanding sampling techniques to collect juvenile fish. Data analysis from field sampling conducted in 2015is ongoing and lab processing is not complete. As such, a complete reporting of data collected during the 2014sampling season is presented, covering data from Segments 17and 18. Further, some objectives are based on long term data collection and insights will become clearer as results accrue through future sampling; therefore, results for each objective may not be specifically discussed in this report. Below, we present the study objectives and several research highlightsDivision of Fisheries, Ilinois Department of Natural Resources Grant/Contract No: Federal Aid Project F-138-R-18unpublishednot peer reviewedOpe

Growth and Survival of Nearshore Fishes in Lake Michigan

This report includes 2007 field season results of a project that began in August 1998. This project’s purpose is to identify factors that contribute to and determine yearclass strength of fishes in nearshore waters of Lake Michigan. This research focuses on Illinois waters of Lake Michigan and is needed because limited data exist on year-class strength and recruitment of nearshore fishes. The focus of this research is to describe patterns of year-class strength and to relate these patterns to a set of factors that allow managers to better predict inter-annual fluctuations in fish populations. After this project was funded, we learned that an artificial reef would be built at one of our nearshore sites. Little quantitative information exists on the role such artificial reefs play in the attraction and recruitment success of fishes in freshwater. Consequently, we added the artificial reef site (plus a nearby reference site) to our sampling protocol to identify how the addition of an artificial reef might attract sport fishes, affect recruitment success, and assess other possible effects on the nearshore fish community.Illinois Department of Natural Resources F-138 R-11unpublishednot peer reviewedOpe
