Description

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); model effect of environmental changes; facilitate end-to-end model construction.
