Developing a coordinated approach to monitoring of coregonine brood and cultured progeny in the R3 FWS Hatchery Program
Supporting evaluation components of the Lake Huron Technical Committee’s cisco reintroduction study: a multi-agency effort to promote cisco recovery in the western basin of Lake Huron (FY19)
The U.S. Fish and Wildlife service conducted two surveys in 2019 aimed at documenting the current distribution, composition, and density of the larval coregonid community in Saginaw Bay. Sampling was limited to pelagic ichthyoplankton and beach seining due to the...
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...
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...
Use of multi-gear sampling to improve abundance estimates of demersal Coregonines in the Great Lakes
Acoustic and mid-water trawl surveys have been used to estimate abundance and biomass of Great Lakes coregonines for decades. Acoustic sampling has potential to be an important tool in the assessment of future coregonine restoration efforts because new populations...
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...
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
During the fall of 2021 and 2022, Lake Whitefish egg deposition was assessed using egg mats and egg pumping along the southern shore of the central and eastern basins in Lake Erie. Sampling was conducted at 12 different locations with 111 individual sites sampled over...
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 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...
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...
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)
