In FY22, we received one year of GLRI funding to explore the feasibility of making and rearing Kiyi or Kiyi-hybrid crosses for the establishment of research stocks at the Little Traverse Bay Band of Odawa Indians (LTBB) Hatchery, Ann Arbor wet lab (AA), and...

Hatchery production and research to support restoration of sustainable Coregonine populations in Lake Ontario (FY24)
This project focuses on the production of Coregonines at the USFWS Allegheny, Lamar, and North Attleboro National Fish Hatcheries, working in partnership with NYSDEC and OMNRF to contribute towards Coregonine reintroduction and restoration and fish community goals...
Evaluating Bloater (Coregonus hoyi) natural reproduction in Lake Ontario
Evaluation of fisheries restoration actions such as the reestablishment of coregonine populations requires a life stage approach to evaluate program success and improve understanding on potential recruitment bottlenecks. Prior to their extirpation, Lake Ontario...
Expanding efforts to document and understand Great Lakes coregonine river spawning – Year 2
Restoration and conservation efforts hinge on the identification of key habitats, such as fish spawning habitats (Lewis et al. 1996; Kondolf 2000), and the potentially distinct populations that use them. Knowledge of these habitats can help to ensure that conservation...
Effects of incubation temperature on survival, growth, morphology, and gene expression of artificially reared cisco (Coregonus artedi): implications for best practices for captive propagation and restoration
A key tool for Great Lakes coregonine restoration is reintroduction via fish stocking. Stocking programs are currently underway, including efforts to restore cisco Coregonus artedi in Saginaw Bay, Lake Huron (Lake Huron Technical Committee 2007; Riley and Ebener 2020)...
Evaluating post-stocking movement, mortality, and habitat use of fall-stocked cisco Coregonus artedi in Saginaw Bay, Lake Huron with acoustic telemetry
The Lake Huron Committee aims to restore cisco Coregonus artedi in Lake Huron (DesJardine et al. 1995; Lake Huron Technical Committee 2023). To that end, the Lake Huron Technical Committee has implemented a plan for re-establishing a population in the main basin of...
Testing habitat’s influence on Cisco reproductive success using egg translocation
Great Lakes Restoration Initiative studies from the Coordinated Science and Monitoring Initiative, Native Fish Restoration, and DOI Steering Committee from fiscal years 2018 - 2022 have rapidly improved our understanding of how habitat influences coregonine spawning...
Defining bloater spawning habitat to inform potential impediments to Lake Ontario bloater reintroduction
Efforts to reintroduce bloater (Coregonus hoyi) in Lake Ontario have been ongoing for 11 years (Weidel et al. 2022). Although more than 1.1 million bloater have been released, the objective of a self-sustaining population has yet to be achieved. Reintroduction efforts...
Implementing science planning methods within the Coregonine Restoration Framework via expert knowledge elicitation and workshop facilitation
Is handling and transport stress limiting post-stocking survival of yearling bloater C. hoyi in Lake Ontario?
Developing a high throughput method to genotype coregonines at a standardized panel of loci for genetic monitoring and parentage-based tagging applications
A central component of coregonine restoration in the Great Lakes is hatchery production, and active supplementation programs are underway in Lakes Ontario and Huron. Importantly, these efforts must consider the decades of work in other salmonids that demonstrate...
Supporting evaluation components of the Lake Huron Technical Committee’s Cisco reintroduction study for FY24
Implementation of Coregonine Population Viability Analysis within the Coregonine Restoration Framework – Year 3
An extensive review of published and raw data was performed to support the best parameterization of unstructured and structured population viability analysis (PVA) models for Lake Erie Cisco. The unstructured model was used to estimate historical population size and...
Integrating historical records to compare historical and contemporary coregonine habitat use in the great lakes
Understanding and comparing historic and contemporary habitat use and distributions of coregonines (Gap Analysis, Box 2) has been deemed essential to inform all boxes of the Great Lakes coregonine restoration framework; there are dependencies between planning boxes...
Resolving the cisco complex of Lake Superior using morphological and genetic tools
Here we seek additional funding to follow-up a previous GLRI-funded project, “Morphologic, geographic and genetic variation among Lake Superior ciscoes.” Our goal was to conduct a comprehensive description of the morphological and genetic diversity of the Lake...
