We propose a pilot project to investigate the effects of artificial rearing on cisco DNA methylation. This project will build on an ongoing project funded in FY24 led by A. Honsey (“Effects of incubation temperature on survival, growth, morphology, and gene expression...

Impact of egg fatty acid signatures on embryo viability in wild and domesticated cisco
One of the major challenges in the aquaculture of bloater (Coregonus hoyi) and cisco (Coregonus artedi) is the low survival rate of larvae from hatchery-reared broodstock compared to wild broodstock. Percent eye-up of bloater eggs from parents fed different diets at...
Evaluation of sequential chemical marking of Oxytetracycline, Alizarin Red S, and Calcein in calcified structures of bloaters (Coregonus hoyi)
This project will investigate the unique chemical marking patterns produced within the otoliths, lower jaw, and ribs of bloaters after sequential immersions of Oxytetracycline (OTC), Alizarin Red S (ARS), and calcein. This project is fully aligned with the Coregonine...
Effects of incubation temperature on survival, growth, morphology, and gene expression of artificially reared cisco (Coregonus artedi): implications for best practices for captive propagation and restoration
A key tool for Great Lakes coregonine restoration is reintroduction via fish stocking. Stocking programs are currently underway, including efforts to restore cisco Coregonus artedi in Saginaw Bay, Lake Huron (Lake Huron Technical Committee 2007; Riley and Ebener 2020)...
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...
