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.
Examining coregonine ecology in Lake Superior using stationary up-looking acoustics
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...
Reviewing management actions in Europe, Asia, and North America to conserve or restore coregonines
David “Bo” Bunnell, USGS researcher describes the many examples of coregonine research globally. He explains…
Artificial Propagation Producing Wild-Like Salmonids
Carl Schreck from Oregon State University explains the challenges and successes of propagating a variety of salmonid species.
When Good Planning Meets Opportunity: The Story of the Epic 2022 Coregonid Year-Class in Lake Superior
Listen to Dan Yule (USGS) talk about the comprehensive sampling strategies implored during 2022 that led to finding a historic year class of coregonids in Lake Superior. Novel genomic analyses were used to identify larval and age-0 coregonids, overcoming longstanding...
Exposure to UV radiation induces hatching and alters growth and development of coregonine eggs
Ph. D candidate Nicole Berry of Miami University – Ohio takes us into a glimpse of her doctoral dissertation research on the potential effects of ultraviolet radiation on coregonine eggs and larvae.
A Reassessment of Historical Cisco Declines in Green Bay, Lake Michigan, and Saginaw Bay, Lake Huron
Ben Rook of the Michigan DNR presents his research on historical cisco populations, highlighting the effects of overfishing, rainbow smelt, and bottom hypoxia in the bays and upper Great Lakes. Here he gives estimates of abundance during the Late 1940s and Early...
SUNY Cortland joins effort to restore native Lake Ontario fish
SUNY Cortland and SUNY Oswego faculty and students are collaborating with the federal Tunison Lake Ontario Biological Station in Cortland and many other agencies and organizations to save a critical piece of the Great Lakes ecosystem. This research project is made...
One of these things is not like the other! Lab & field observations for Lake Whitefish and Cisco
Kelly Hoyer, a Ph. D candidate at Central Michigan University, talks about her work on larval Lake Whitefish and Cisco. She compares the two species and their interactions with various predators and how the two fish differ....
Anishinaabe tribes work to save Michigan whitefish
Commercial fishers are catching fewer whitefish in parts of the Great Lakes – and the Anishinaabe people are trying to figure out why. The Little Traverse Bay Bands of Odawa Indians is looking into low reproduction rates for the fish. Great Lakes whitefish are pretty...
Saugeen Ojibway Nation and the ciscoes of Lake Huron
Alexander Duncan from the Chippewas of Nawash Unceded First Nation describes the historical significance of ciscoes to the SON and the relevance these fish still hold today with their current population status. https://youtu.be/qEUk7Ydnra4?si=dxw7H4CEh59Qf9Ew
Two hundred years of historical spawning data for coregonines in the Great Lakes of North America
Cory Brant (USGS) details the history of coregonines in the Laurentian Great Lakes, the importance they held, factors contributing to their decline, and how he has created a database to archive this data, CORHIST. https://youtu.be/Q-Xq3v0_mOQ?si=w6WqG3hIeLSJSLgH
Whole-lake acoustic telemetry and eDNA to evaluate Cisco restoration in an inland lake
Alex Koeberle, Cornell University Ph. D student, describes tracking ciscoes in a fingerling lake in New York. He discusses the potential size/cost benefits of stocking age-0 ciscoes, and how he tracks fish using traces of their DNA left in the water....
From planktivore to piscivore: rethinking the trophic role of Cisco in the Lake Michigan Food Web
Jory Jonas and Ben Turschak from the Michigan Department of Natural Resources present their ongoing research about the shift being seen in ciscoes' diets. They compare the differences diet may have on body size and isotope composition....
Resolving morphologic and genetic variation in the Lake Superior cisco complex
Drs. Amanda Ackiss and Owen Gorman discuss the phenotypic and genotypical variances of the cisco species found in Lake Superior, and compare how these match up to historically categorized forms. https://youtu.be/XbP7_wI_oNs?si=aTHXGz8BArcUTZPs
