Bioeconomic mussel fisheries management model


Bioeconomic mussel fisheries management model


The bioeconomic mussel fisheries management model developed under the EU SPICOSA project, is a decision support system designed to manage mussel fisheries in costal regions. The model utilizes the systems approach framework (SAF), which is a method for addressing policy issues in a holistic manner (

The bioeconomic model is a fully coupled model consisting of four components: (1) an empirical submodel describing the relationship between nutrient loadings and phytoplankton primary production; (2) a process-based ecological submodel describing the dynamics of phytoplankton and blue mussel biomass; (3) an agent-based mussel fishing submodel that allows the fishermen to make decisions regarding fishing effort based on regulations, available mussel biomass, and expected cost and revenue; and (4) an economic submodel for cost-benefit analysis and for simulating the expected profit.

The model has been set up for the Limfjord, a temperate eutrophic estuary in Northern Denmark.
