ECOPATHEcopath 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);
  • Model effect of environmental changes;
  • Facilitate end-to-end model construction.
