Development of eco-region benchmarks of fish productivity in freshwaters: incorporating habitat, water temperature, nutrients, and flow as primary drivers of productivity of fishes that support commercial, Aboriginal, and recreational fisheries


A 2011 Canadian Science Advisory Secretariat (CSAS) workshop recommended developing a tool to measure the effectiveness of habitat compensation programs. This project will contribute by creating benchmarks for productive capacity in different eco-regions in Canada. Productive capacity will be measured as the average biomass of target fish species (or groups of species) within eco-regions, which are defined as broad geographic areas with similar aquatic ecology. The benchmarks developed will be used as a measure and standard to avoid or offset harm that could result from habitat degradation. Using benchmarks from eco-regions rather than specific sites will support an ecosystem-based approach to resource management.
