The abundance of the deepwater preyfish Kiyi (Coregonus kiyi) in Lake Superior makes it a high-value target for restoring extirpated populations in Lakes Michigan, Huron, and Ontario. Managers from several Great Lakes have informally indicated strong interest in...

Implementation and testing of hatchery enhancements at Allegheny National Fish Hatchery to increase production and improve health and quality of juvenile bloater raised for restoration stocking in Lake Ontario
The proposed project will install 16 15-foot circular fiberglass tanks to replace 10 45-year-old concrete raceways (scalable down to 8 tank option). The project will also assess a side-by-side production level comparison of fish health, water use, fish growth,...
Deep-water cisco captive broodstock developed from wild-caught juveniles: proof of concept with Lake Michigan bloater
Hatchery broodstocks (Coregonus artedi and C. hoyi) created via fertilizing eggs with sperm from wild spawning populations or captive brood stock fuel current restoration efforts for ciscoes in the Great Lakes. But, creating these broodstock involves hazards to access...
Developing a coordinated approach to monitoring of coregonine brood and cultured progeny in the R3 FWS Hatchery Program
A coordinated approach to monitoring of a coregonine brood and cultured progeny in the R3 FWS hatchery program
Broodstock management and monitoring programs are vital components of all types of stocking initiatives (e.g. Captive, Supportive, restorative, rescue). Broodstock collection and development should aim to preserve genetic diversity and minimize inbreeding and stocking...
Region 3 wild coregonine brood stock collection activities for FY 2021 in support of restoration activities on Lake Huron and Lake Ontario
The U.S. Fish and Wildlife Services Midwest Region Fisheries Program carried out two projects in support of a multi-agency effort to restore coregonid populations in Lakes Huron and Ontario. The first project began in 2015 when USFWS began documenting the spawning...
Examining the potential for unrepresentative sampling during cisco Coregonus artedi gamete collections for the Saginaw Bay restoration effort
Great Lakes cisco populations declined during the 19th and 20th centuries due to factors such as overfishing, habitat degradation, and interactions with invasive species (Van Oosten 1930; Crowder 1980; Myers et al. 2009; George 2019). Cisco are now considered...
Developing a Great Lakes-wide database of coregonine stocking
This dataset is the result of coordinated efforts to compile data associated with stocking events for whitefishes and ciscoes (members of the Coregoninae subfamily) of Great Lakes origin. The dataset includes more than 4,700 records associated with coregonine...
Hatchery production, fish health surveillance, and research to support restoration of sustainable coregonine populations in Lake Ontario (FY20)
Project objectives include: (1) Production of coregonines at the USFWS-ANFH and NEFC hatcheries, working in partnership with USGS-TLAS, NYDEC, MNRF, and USFS LOBS represents progress towards fish community goals outlined by the GLFC Lake Ontario Committee through...
Region 3 wild coregonine brood stock collection activities for FY 2020 in support of restoration activities on Lake Huron and Lake Ontario (2020)
The U.S. Fish and Wildlife Services Midwest Region Fisheries Program carried out two projects in support of a multi-agency effort to restore coregonid populations in Lakes Huron and Ontario. The first project began in 2015 when USFWS began documenting the spawning...
Susceptibility and clearance of Aeromonas salmonicida (furunculosis) in Coregonus artedi (lake herring)
Aquaflor® (florfenicol) and Terramycin®200 for Fish (oxytetracycline) are approved medications in the United States for delivery with feed to control mortality in salmonids due to furunculosis associated with Aeromonas salmonicida. The purpose of this study was to...
Region 3 wild coregonine broodstock collection activities for FY 2019 in support of restoration activities on Lake Huron and Lake Ontario
The U.S. Fish and Wildlife Services Midwest Region Fisheries Program carried out two projects in support of a multi-agency effort to restore coregonid populations in Lake Huron and Lake Ontario. The first project began in 2017 when USFWS started collecting cisco...
Captive coregonid brood stock management facilities at Jordan River National Fish Hatchery
Production, fish health surveillance, and research at Northeast Region U.S. Fish & Wildlife Service (USFWS) facilities to support restoration of sustainable coregonid populations in Lake Ontario
How many cisco should be stocked, and at what life stage?
Historically, members of the coregonine complex (Coregonus spp.) were the most abundant and ecologically important fish species in the Great Lakes (especially the cisco C. artedi), but anthropogenic influences caused nearly all populations to collapse by the 1970s....
Are there differences in larval and juvenile gene expression between hatchery and wild coregonids?
Management agencies are investigating best practices for coregonid (C. artedi and C. hoyi) culture, stocking, and broodstock development. However, before large scale production can begin, decisions about the sources of broodstock, culture practices, and stocking rates...
Quantifying a potential mechanism between ice cover and cisco recruitment success: what role does light play in cisco embryonic development and larval survival?
Over the past several decades, Coregonus recruitment has dwindled to unprecedented levels for unknown reasons. Coregonus species are fall spawners whose embryos incubate under ice throughout the winter and hatch in spring. Recent changes in ice cover coupled with poor...
Kiyi reproductive phenology in Lake Superior
Kiyi historically occurred in Lakes Huron, Michigan, Ontario, and Superior. Today they occur in Lake Superior. Reestablishing Kiyi into lakes where it went extinct is a topic of discussion among Laurentian Great Lakes fishery managers. An impediment to re-introducing...
