We are using historical data form IISD-ELA on lakes that have undergone disturbance, as well as lakes with gradients of productivity to evaluate correlates and drivers of fish productivity. This is part of a larger effort involving researchers from the IISD-ELA,  University of Waterloo, Wilfrid Laurier University and the University of Manitoba.   Haley Macleod led this work in our lab, adapting traditional production estimation methods to evaluate the impacts of environmental changes and gradients on fish production.
