Eastern Bering Sea 1990s Ecopath model

Rpath inputs for the eastern Bering Sea 1990s Ecopath model (53 biological groups and 1 fleet).

Usage

Ecosense.EBS

Format

An unbalanced Rpath model object that contains:

model: A data.table containing Ecopath unbalanced ecosystem parameters (base parameters and fisheries).
diet: A data.table containing the Ecopath model's diet matrix.
stanzas: Parameters for multistanza groups.
pedigree: A data.table containing the data quality (pedigree) for the Ecopath model.
