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
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...
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...
