Impact model: EcoTroph

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.
