Previous attempts to rehabilitate Great Lakes coregonines (Coregonus spp.) have been unsuccessful due to the reliance on fry and stocking on top of existing populations that made evaluations difficult. After the demise of cisco and deepwater coregonines d ...

RATIONALE: In a recent study we found that the timing of reproductive maturation in siscowet populations in southern Lake Superior was synchronized within populations east and west of the Keweenaw Peninsula, and occurred from August to October as observed ...

The Red Flags Analysis (RFA) is an annual procedure to help monitor and communicate the progress of chinook salmon stocking policies in Lake Michigan. It was developed by the Salmonid Working Group (SWG) under the Lake Michigan Technical Committee (LMTC). ...

Restoration of self-sustaining lake trout populations in the Great Lakes has been slow, except in Lake Superior and local populations in Lake Huron. Potential reasons may be related to the inability of hatchery-reared lake trout to select appropriate spaw ...

The proposed research seeks to better understand downstream migration (i.e., outmigration) of newly metamorphosed sea lamprey larvae (transformers) to inform development of new trapping methods for control of this invasive species in the Great Lakes. Our ...

The muskellunge (Esox masquinongy) is a native Great Lakes apex predatory fish that has experienced declines and extirpations in many areas resulting in numerous restoration efforts. Despite localized understanding of genetic diversity in some locations, ...

Lake-wide adult sea lamprey abundance estimates are a key metric of sea lamprey control program success reported to stakeholders and resource managers. Lake-wide sea lamprey abundance is estimated from a combination of stream-specific mark-recapture estim ...

The spawning behavior and early life history of lake trout has been a focus of research for several decades, in an effort to understand the failure of stocked lake trout to re-establish self-sustaining populations in the Great Lakes. Physical characterist ...
