Ecopath with Ecosim (EwE) is trophodynamic modelling software that uses a mass-balance approach to describe ecosystem based, marine food web interactions.
Model summary
The Ecopath (stable state) model represents the Tasman and Golden Bay marine ecosystem. Ecosim is the dynamic extension to the Ecopath model (Walters et al. 1997), and is used to simulate ecosystem dynamics in the Nelson Bays region (aka Tasman and Golden Bays). The Tasman and Golden Bay EwE model uses the standard EwE modelling framework, which is available for free here: www.ecopath.org
