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
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....
Inventorying Great Lakes survey and life history information to facilitate coregonine science, conservation, and restoration
Population models are a critical tool for informing native fish conservation and the types of models that can be developed are determined by data availability. In the Great Lakes, the size of the ecosystems and the multi-organizational management approach means...
Building an adaptive tool for mapping habitat and species to support the Great Lakes coregonine conservation and restoration framework
Coregonines have declined substantially over the past century throughout the Great Lakes. A basin-wide framework, adopted by the Council of Lake Committees, has been developed to conserve and restore these ecologically and economically important native fishes. We are...
Identifying and characterizing coregonine spawning habitat in Lake Erie
Historically, Lake Erie supported large catches of Lake Whitefish and Cisco, but presently Cisco are considered extirpated and Lake Whitefish catch rates are highly variable (Oldenburg et al. 2007). For example, Lake Whitefish commercial harvest increased in the...
Morphological and genomic assessment of putative hybridization among deepwater ciscoes and between deepwater ciscoes and typical artedi in Lakes Michigan and Huron
Species diversity can be lost through a combination of demographic decline and hybridization (Mallet 2005; Seehausen 2006). Regarding diversity losses among Ciscoes (subgenus Leucichthys, genus Coregonus) across the Great Lakes, the demographic decline in the 20th...
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 taxonomy of the cisco (Coregonus) species complex in the Laurentian Great Lakes and Lake Nipigon
The manager endorsed Coregonine Restoration Framework (CRF) identified a need for reviewing and updating the taxonomy of ciscoes, and this task was assigned to the first of four science teams established in the Planning Phase of the CRF. The ‘Resolve cisco taxonomy’...
Morphological and genomic assessment of putative hybridization among deepwater ciscoes and between deepwater ciscoes and typical artedi in Lakes Michigan and Huron – Year 2
Although species diversity can be lost through hybridization (Mallet 2005; Seehausen 2006) and hybridization has been common among ciscoes (genus Coregonus, subgenus Leucichthys; Smith 1964; Todd and Stedman 1989; Eshenroder et al. 2016; Ackiss et al. 2020), the...
Implementation of Coregonine population viability analysis within the Coregonine restoration framework – Year 2
The Coregonine Restoration Framework provides an adaptive management structure to guide restoration of this suite of species in the Great Lakes Region. Initial steps in this effort are underway with the establishment of four science teams [Resolve Taxonomy, GAP...
Implementation of a gap analysis: comparing 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 (Planning Phase) of the Great Lakes coregonine restoration framework (CRF). We are requesting support...
Establishing genetic baselines for historic coregonine diversity in Lake Superior
New research surveying morphological and genetic data across contemporary diversity in the cisco species complex has highlighted critical gaps in our understanding of the historic deepwater diversity in Lake Superior. Historic ciscoe diversity in Lake Superior, which...
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...
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...
Historical habitat use by Coregonus artedi in Lake Michigan
With the global-scale loss of biodiversity, current restoration programs have been often required as part of conservation plans for species richness and ecosystem integrity. The restoration of pelagic-oriented cisco (Coregonus artedi) has been an interest of Lake...
Development of a genetic map for cisco and bloater
We constructed a linkage map for cisco (Coregonus artedi), an economically and culturally important fish in the Great Lakes and across North America, which previously lacked a high-density haploid linkage map. We used diploid and haploid cisco from northern Lake Huron...
Are cisco and lake whitefish competitors in the Great Lakes? Implications for future reintroduction efforts
The overall objective of this project was to evaluate historical commercial gill net fishery data available for State of Michigan waters of Lakes Superior, Michigan, and Huron for evidence of potential negative interactions between Cisco Coregonus artedi and Lake...
Dedicated surveys to describe the distribution and abundance of a remnant cisco population in Green Bay
Contemporary spawning of cisco and lake whitefish is not known to occur in southern Green Bay but in recent years a small number (< 10 per year) of cisco adults have been recovered along the Door Peninsula, and lake whitefish larvae have been captured in drift...
Historical and contemporary genetic diversity of Coregonus species from Lake Michigan
Advancements in molecular biology methods have allowed researchers to analyze genetic variation in extinct or extirpated species where minuscule amounts of cellular material remain. Here for the first time, we have leveraged one of these methods -...
Historical habitat use by Coregonus artedi in the upper Great Lakes and critical embayments
The restoration of the once abundant cisco (Coregonus artedi) is a management interest across the Laurentian Great Lakes. To inform restoration, we describe historical distributions of cisco in the upper Great Lakes (i.e., Lakes Superior, Michigan, and Huron) by...
Building molecular tools for coregonine species identification
The larval phase of Coregonus spp. represent a bottleneck in year class strength that is not well understood in extant populations and could present an impediment for coregonine restoration efforts in the Great Lakes. The use of species-specific DNA sequences to...
