Bill Carter (USFWS) describes his master’s work on the broad whitefish, the second largest coregonine species.
Randy Brown (USFWS – retired) presents on 30 years worth of research and experience working with the Yukon River Inconnu, the world’s largest coregonine.
Kristen Behrens (University of Michigan) delivers hot off the press data about genomics markers that could possibly determine sex in ciscoes.
Dr. Dan Isermann (University of Wisconsin – Stevens Point) presents on his research on Understanding the behavior and importance of lake whitefish spawning in tributaries to southern Green Bay.
Taylor Brown (Cornell), provides an in depth look at the variables potentially driving recruitment dynamics of the cisco and lake whitefish within…
Lee et al. have applied a data-limited model to historic records of commercial catch combined with some basic life history information to estimate the population size of cisco in Lake Erie prior to the collapse of the fishery in the early 20th century. The model uses...
This spring, DEC in cooperation with the U.S. Fish and Wildlife Service, began a ten-year experimental reintroduction of cisco into the New York portion of Lake Erie to determine if they can survive to adulthood in the lake as it exists today. The initial stocking of 90,000 yearlings this May occurred offshore of Dunkirk, NY. The results of this work will help inform future cisco rehabilitation decisions in New York and elsewhere.
The Coregonine Steering Committee is pleased to announce a call for proposals for the 2026 fiscal year! See the attached link for guidelines and priorities for the FY26 RFP.
The Coregonine Science Webinar Series is on summer hiatus! Webinars will resume in September, check back for more information!
Efforts are underway to determine if a lost native species of fish in Lake Erie can be reintroduced from its descendants that have been found on the opposite side of Pennsylvania. Doug Fischer, nongame fisheries biologist and ichthyologist for the Pennsylvania Fish...
Todd Hayden (Michigan State University) and Joseph Schmitt (USGS) discussing movement and habitat use of cisco in Lakes Huron and Erie.
Katelyn King (MDNR) presents her work with the Gap Analysis science team identifying historical and contemporary cisco spawning habitat in Lakes Erie and Ontario. Laura Lee (USFWS) discusses newly created predictive models that give insight into the population...
Please join us for the next installment of the Coregonine Science Webinar Series, Friday May 2nd at 12:30 pm EST. Katelyn King (MDNR) and Laura Lee (FWS) will present "Restoration planning models to support Great Lakes cisco restoration." Join by registering at...
Corbin Hilling and Robin DeBruyne of USGS present their findings of new spawning locations of lake whitefish in Lake Erie. They also describe over-wintering conditions on a known spawning reef such as ice effects and hydrodynamics.
Cory Brant, Jim McKenna, Jon Doubek, Nikki Berry, and Steve Pothoven explain the importance of nursery habitat to lake whitefish.
Trevor Pitcher from the University of Windsor explains his research regarding the challenges of producing fish in hatcheries, from gamete quality to transport stress. He teaches us the history and future of fish hatcheries and reintroduction programs.
Kyle Stratton of OMNR and Alex Gatch of USGS give subsequent presentations about behaviors of ciscoes in Lakes Superior and Ontario. They will talk about challenges with these fish, tagging in the winter, and what the telemetry data tells us.
UWSP researcher Jared Homola describes the genetic structure of lake whitefish in Lake Michigan and its application to lake whitefish management units.
Mike Lowe of USGS presents his findings of what reefs contribute to the current lake whitefish fishery around Buffalo Reef, Lake Superior. By looking at differences between historical spawning sites and those used today, he creates comparisons of habitat quality and questions prey availability.
The Coregonine Steering Committee is pleased to announce a call for proposals for the 2025 fiscal year! See the attached link for guidelines and priorities for the FY25 RFP.
Todd Hayden (Michigan State University) describes the seasonal movements and habitat use of the shorthead cisco in the Les Cheneaux Islands of Lake Huron. Joseph Schmitt (USGS) presents on behalf of Richard Kraus on the movement, habitat use, and survival of hatchery-reared ciscoes in Lake Erie.
USGS researchers Andrew Honsey and Ralph Tingley III describe habitat use and migratory behaviors of Great Lakes cisco in Lake Huron and Lake Michigan…
Brian Weidel with the USGS Great Lakes Science Center and Dimitry Gorsky from the FWS Great Lakes Fish and Wildlife Conservation Office are guests on the Fish of the Week! podcast.
Recent Lakehead University graduate, Dr. Ryan Grow presents some of his dissertation work regarding acoustic sampling. He compared up-and-down-looking acoustics to traditional gillnet surveys. He estimated cisco abundances and fish movements, concluding that...
