Continue to collect baseline information of larval coregonine community validated with genetic species identification. Sampling of the Saginaw Bay larval coregonine community was completed during the spring of 2021 using pelagic ichthyoplankton tows, beach seines, and...

Stocking Strategies
Continued assessment of Cisco reintroduction in Saginaw Bay, Lake Huron
There is a growing need to evaluate whether hatchery-reared Cisco (Coregonus artedi) survive following stocking and are successfully recovering in the Great Lakes (Claramunt et al., 2019; Rook et al., 2021; Bunnell et al., 2024; Fielder and McDonnell, 2024; Koeberle...
Continuing evaluation components of the Lake Huron Technical Committee’s Cisco reintroduction study for FY25
Cisco (Coregonus artedi) are functionally absent from the western main basin of Lake Huron and as such restoring Cisco “to a significant level” (DesJardine, 1995) remains an unmet objective for Lake Huron management agencies (Riley and Ebener, 2020). In 2007 the Lake...
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...
Is handling and transport stress limiting post-stocking survival of yearling bloater C. hoyi in Lake Ontario?
Bloater (C. hoyi) have been stocked in Lake Ontario for 11 years with limited success (15 total recaptures; Weidel et al., 2022). Short term (1-12 days) post-stocking survival has been estimated at 42% with 22% of the mortality occurring in the first hour post-release...
Supporting evaluation components of the Lake Huron Technical Committee’s Cisco reintroduction study for FY24
Cisco (Coregonus artedi) are functionally absent from the western main basin of Lake Huron and as such restoring Cisco “to a significant level” (DesJardine 1995) remains an unmet objective for Lake Huron management agencies (Riley and Ebener 2020). In 2007 the Lake...
Supporting evaluation components of Lake Huron Technical Committee’s cisco reintroduction study: a multi-agency effort to promote cisco recovery in the western main basin of Lake Huron (FY21)
The U.S. Fish and Wildlife service conducted larval coregonine surveys in 2021 aimed at documenting the current distribution, composition, and density of the larval coregonid community in Saginaw Bay. Sampling of the ichthyoplankton community was limited to pelagic...
Supporting evaluation components of the Lake Huron Technical Committee’s Cisco reintroduction study: a multi-agency effort to promote Cisco recovery in the western main basin of Lake Huron (FY22)

Supporting evaluation components of the Lake Huron Technical Committee’s Cisco reintroduction study for FY23
Cisco (Coregonus artedi) are functionally absent from the western main basin of Lake Huron and as such restoring cisco “to a significant level” (DesJardine 1995) remains an unmet objective for Lake Huron management agencies (Liskauskas et al. 2007). In 2007 the Lake...
Can stocked Bloater (Coregonus hoyi) survival be increased with environmental conditioning?
Bloater (Coregonus hoyi) were historically an important component of the Lake Ontario fish community but the species was likely extirpated by the 1970’s. A binational restoration has stocked over one million Bloater into Lake Ontario since 2012, however, low...
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....
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...
