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...
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....
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
Captive coregonid brood stock management facilities at Jordan River National Fish Hatchery
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...
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 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...
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...
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...
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...
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...
Inventory and assessment of coregonine spawning locations in lakes Erie and Ontario, including connecting channels
This project involved two phases. First, to identify locations of key habitats for coregonines in lakes Erie and Ontario and their respective connecting channels, we conducted a literature review of historical spawning, nursery, and adult habitat sites where...
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...
Spatio-statistical modeling and field validation of coregonine spawning and nursery locations for the Great Lakes, including connecting channels and major tributaries
This research builds on the spawning habitat inventory work [GLRI: Inventory and assessment of coregonine spawning locations in lakes Erie and Ontario, including connecting channels] by using data gleaned from the previous study to develop descriptive and predictive...
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...
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...
Genetic diversity among Great Lakes cisco species: exploring taxonomic and population boundaries
Ciscoes (Coregonus artedi, hoyi, kiyi, zenithicus, and nigripinnis) once formed a diverse species flock in the Great Lakes. While several taxa appear to have been extirpated, those that remain are an important part of the Great Lakes food web. Deepwater forms (C....
How does ecological function correspond to morphology in Great Lakes coregonines?
Human activities have caused widespread biodiversity loss, particularly in freshwater systems. For example, historical fish assemblages of the deepwater habitats of the Laurentian Great Lakes were dominated by up to eight closely related taxa from the genus Coregonus....
