Fishery managers in the Lake Michigan basin have new information about the journeys and survival of wild and hatchery-raised steelhead salmon (Oncorhynchus mykiss). Managing the fish effectively requires understanding the proportion of fish coming from hatcheries or the wild, generally, and from which hatchery and which river tributary, specifically.
For over a decade, the Great Lakes Fishery Trust has supported Lake Superior State University’s (LSSU’s) vision to expand its capacity of its former Aquatic Research Lab by constructing a new facility at the nexus of the upper Great Lakes.
Nearly four years in the making, a new fishing access is finally coming to fruition. In 2018, the City of Cheboygan reached out to Tip of the Mitt Watershed Council, looking for assistance in improving Major City Park. Erosion along the Cheboygan River was something we could tackle; fishing platforms turned out to be the answer, as they keep foot traffic to a minimum and preserve river banks.
The Boardman-Ottaway: A River Reborn is the largest comprehensive dam removal effort in Michigan’s history and one of the most significant in the Great Lakes Basin. The overall project involved removing three dams (Brown Bridge, Boardman and Sabin) on the Boardman River, originally known as the Ottaway by the Ojibwa and Odawa Native Americans.
The Great Lakes Fishery Trust (GLFT) is now accepting proposals under its Habitat Protection and Restoration grant program. This request for proposals (RFP) will be used for the disbursement of up to $500,000 in grants in 2022.
A new project using a sophisticated system of receivers across Saginaw Bay and Lake Huron will help guide researchers in their efforts to return state-threatened lake sturgeon to the Saginaw Bay system. Some of the funding that made this project possible came from the GLFT.
GLFT is now accepting Ecological and Biological Research to Inform Management preliminary proposals. This request for proposals process will be used for the disbursement of up to $1.3 million in grants.

Conservation organization Huron Pines has completed the fourth in a series of road/stream crossing restoration projects reconnecting vital coldwater habitat on two tributaries of the Thunder Bay River. Some of the funding that made this project possible came from the GLFT.
A critical knowledge gap in efforts to conserve and restore cisco has been cisco taxonomy. New research using genomic tools to clarify cisco population structure and taxonomy is yielding exciting information that challenges the current understanding of the Great Lakes cisco family tree.
The GLFT is pleased to announce Jon Beard as the new trust manager. Mark Coscarelli has retired after more than 20 years of success and dedication to the ecological health of the Great Lakes and sustainability of its fish populations.
For years, the Chinook collected valuable data on the Great Lakes fishery, such as the impact of sea lampreys and the effectiveness of stocking programs. Its replacement, named after Dr. Howard Tanner, was funded in part by a grant from the GLFT.
Thanks to a recent GLFT project, fisheries managers now have two computer models, developed by a team of researchers who wondered if they could find a better way to determine relative recruitments of spawning populations in a mixed environment.
In order to understand Thiamine Deficiency Complex—which contributes to premature death in lake trout—researchers looked into whether certain fish genes produce thiaminase de novo, or at a cellular level.
In 2014, the GLFT convened an aquatic connectivity workshop to identify the types of decision-support tools that resource managers and regulators need and would use to guide decisions on where to improve fish passage or remove dams in the Great Lakes basin.
The GLFT funded a research project to (1) better understand the state’s more naturalized Chinook salmon population, (2) assess potential differences between naturalized and hatchery-stocked fish, and (3) use the results to inform decisions about cultivating self-sustaining stocks of desirable introduced species.
The Stream Fish Population Trend Viewer was developed to serve as a simple, centralized location for users to get up-to-date information on regional and local fish trends. The map-based displays were designed to be interactive, allowing users to pick the fish species they want to view, instead of going through biologists at the MDNR Fisheries Division.
Dr. Riseng worked with a team to develop the Great Lakes Aquatic Habitat Framework, a database used to classify habitats for different species within the Great Lakes basin. It is currently in its last year, with plans to maintain the database going forward.
