North West Shelf Joint Environmental Management Study:InVitro Inputs - Fin fish population dynamics

Updated: 2006-07-19

Fish population dynamics are represented by age-structured models that account for reproduction, natural mortality and fishing mortality. These models are calibrated for the major species groups and are detailed in Sections 3 and 15 in the companion model specification report (Gray et al. 2006). The selection of the parameters for each species was done by running the historical period of the model over a range of values of these parameters, and comparing the initial biomass of the simulation to a range of species biomass that was thought to occur in nature. Parameters were selected at three levels within this range of biomass to give the optimistic, base-case and pessimistic specifications.
