Ecopath with Ecosim

Ecopath with Ecosim is a modeling tool used by scientists to understand and predict how marine and freshwater ecosystems function. Ecopath creates a static snapshot of the energy flow and relationships among different species and groups, showing who eats whom and how energy moves through the system. Ecosim then simulates how these ecosystems change over time in response to environmental shifts, fishing, or other impacts. Together, they help scientists assess ecosystem health, manage resources sustainably, and make informed decisions to protect aquatic environments.
