Project Details
This project located sites for lake trout restoration at Lake Michigan’s Southern Refuge. In years one and two researchers used a remotely-operated vehicle and beam trawling to identify spawning sites and began qualitative evaluation (presence/absence) of egg deposition density and fry production. In year two and continuing into year three researchers evaluated sites using quantitative techniques adapted from well-established scuba methodology. Results were used to suggest further management options.
