Project Details

Lake Michigan's Mid-Lake Reef Complex (MLRC) was a very important spawning area for indigenous lake trout. Techniques developed for a concluding (June 2008) GLFT project demonstrate distinct smaller sub-reefs within each main reef, each with eggs deposited and sac-fry produced, of statistically distinguishable egg deposition densities. This study provided a more complete assessment of the MLRC's total spawning habitat by a targeted search for additional sub-reefs.
