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.

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...
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...
Developing a Great Lakes-wide database of coregonine stocking
A database of information associated with the release of hatchery-raised Coregonine fishes of Great Lakes origin was constructed and populated with all available records (>4,700) of stocking events. The information includes species, quantities, life stages, source...
