Project Summary

Lake whitefish in Lake Michigan have experienced substantial fluctuations in recruitment and abundance over the last decade and much of this variation appears to be asynchronous across stocks. Genetics represents a powerful tool for stock identification that could facilitate investigation of recruitment dynamics and stock-specific harvest. However, currently available genetic markers are not powerful enough to accurately delineate stocks. Our goal is to use genomic techniques to improve resolution of stock structure in lake whitefish.
