Ecopath with Ecosim

University of British Columbia Fisheries Centre

Ecopath with Ecosim (EwE) is a free ecological/ecosystem modeling software suite. EwE has three main components: Ecopath - a static, mass-balanced snapshot of the system; Ecosim - a time dynamic simulation module for policy exploration; and Ecospace - a spatial and temporal dynamic module primarily designed for exploring impact and placement of protected areas. The Ecopath software package can be used to address ecological questions; evaluate ecosystem effects of fishing; explore management policy options; analyze impact and placement of marine protected areas; predict movement and accumulation of contaminants and tracers (Ecotracer); and model effects of environmental changes.
