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 is leading this work in our lab. We will use both traditional production estimation methods and biomass size spectral approaches to estimating fish production. This research is funded by Manitoba Hydro, MITACS and the IISD-ELA.
