Coregonine species in the Great Lakes, such as Cisco and Bloaters, historically represented a substantial component of the forage base for native cold-water fish like Lake Trout and Atlantic Salmon. Extirpation or depletion of deepwater Bloater populations has left...

Enhancing Kiyi (Coregonus kiyi) research to support the conservation and restoration of deep-water coregonine diversity in the Laurentian Great Lakes
The deep-water coregonines of the Coregonus species complex (including C. hoyi, C. kiyi, C. nigripinnis, C. zenithicus, C. johannae, and C. reighardi) in the Laurentian Great Lakes were among the fishes most impacted by overfishing, invasive species, and habitat...
Examining the potential for unrepresentative sampling during cisco Coregonus artedi gamete collections for the Saginaw Bay restoration effort – Year 2
The cisco Coregonus artedi restoration effort in Saginaw Bay utilizes gametes sourced from northern Lake Huron, in the Les Cheneaux Islands and Drummond Island region (LHTC 2007). Gametes have been collected from bays in the Les Cheneaux area and Whitney Bay (Drummond...
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...
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...
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...
Developing a coordinated approach to monitoring of coregonine brood and cultured progeny in the R3 FWS Hatchery Program
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...
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,...
Hatchery production and research to support restoration of sustainable coregonine populations in Lake Ontario
This project focuses on the production of Coregonines at the USFWS-ANFH and NEFC hatcheries, working in partnership with USGSTLAS, NYSDEC, OMNRF, and USFS-LOBS to further progress towards fish community goals outlined by the GLFC Lake Ontario Committee (LOC) through contributing to Coregonine reintroduction and restoration. Production requests originate from the LOC and the NYSDEC. Fish health monitoring is a required component of the production program to transfer fish, maintain optimal fish health in culture facilities, and facilitate the restoration of both the natural forage base and the predatory Lake Trout populations in the Great Lakes. Production of bloater (Coregonus hoyi) in FY22 is part of a multi-year restoration effort for Lake Ontario.
Hatchery production, fish health surveillance, and research to support restoration of sustainable coregonine populations in Lake Ontario
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
Lake Superior ciscoe spawning and winter ecology
This proposal expands on our recent work collecting ciscoes in winter near Grand Island, Michigan. This previous Coregonine Restoration Program funded project started the process of gathering data necessary to base Kiyi (Coregonus kiyi) restoration management...
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...
