Pennsylvania Project

Defining oxythermal performance metrics for use in physiologically guided abundance models of diverse coregonid ecotypes

June 2024 - May 2026


Participating Agencies

  • Great Lakes Fishery Commission

Recruitment failures have led to declines of Lake Whitefish (Coregonus clupeaformis) and Cisco (C. artedi sensu lato) throughout the Great Lakes and in inland lakes. Maintaining, restoring, and the re-establishment of coregonid populations requires understanding environmental drivers of population processes and how population-specific biology may need to be integrated into hatchery-based culturing and stocking practices. This project will quantify the oxythermal performance of coregonid populations and examine whether populations from different environments exhibit habitat-relevant differences in physiology.
