Growth and survival rate of nearshore fishes in Lake Michigan, 2012

Abstract

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 2012field season and marks the fifth year 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 2013is ongoing and lab processing is not complete. As such, a complete reporting of data collected during the 2012sampling season is presented, covering data from Segments 15and 16. 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 highlights.
