EcoTroph is a "trophodynamic" model where ecosystem functioning is modeled as a flow of biomass up the food web through predation and ontogenetic processes. Within the framework of FISH-MIP, EcoTroph is used to model biomass of marine organisms and is implemented at global scale.

Information for the model EcoTroph is provided for the simulation rounds shown in the tabs below. Click on the appropriate tab to get the information for the simulation round you are interested in.
