One-line model description Ecopath with Ecosim (EwE) is an ecological modeling software suite for personal computers
Extended model description Ecopath with Ecosim (EwE) is an ecological modeling software suite for personal computers. 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;
  • Evaluate impact and placement of marine protected areas;
  • Evaluate effect of environmental changes.
