This edition of Research Notes highlights the research contributions by Dr. Brian Roth and team on the diets of predatory fish that were supported by GLFT.
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.
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.
Lake whitefish numbers are declining substantially in the Great Lakes, concerning those who highly value the species. Learn about recent research contributions on lake whitefish supported by the GLFT.
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.
A team of researchers hypothesized that river plumes would provide an excellent place for larval yellow perch, round gobies, and alewives to grow. Learn how they tested their hypotheses.
