Catch production A Fishery is in EconMult defined as a unique Fleet / Targeted species combination. The total catch within each fishery may include all biomass units defined in the model. Each biomass unit vessel catch is computed by Cobb-Douglas production function, applying two input variables: Number of fishing days d) and Biomass unit x). In the matrix below each column represents a fleet group and each row a targeted species so each element in the matrix is a fishery and gives the vessel catch of the biomass units represented. The biomass units represent all the targeted species. Each catch is represented a Cobb-Douglas production equation as shown in the vessel yield matrix (Y):
