Economic Modeling of Fisheries Systems
Summary
Economic modeling of fisheries systems examines interactions between fish populations, market forces and policy instruments to inform sustainable management and socio-economic welfare. Central aims include estimating the value of fishery rents, assessing the ripple effects of fishing activities across supply chains and forecasting the outcomes of regulatory measures such as catch limits or effort controls. A spectrum of quantitative tools—ranging from input–output frameworks that map inter-industry flows to computable general equilibrium models that capture market adjustments—has been adapted to fisheries contexts. Bioeconomic models integrate population dynamics with profit-maximising behaviour, while emerging interdisciplinary approaches embed ecological networks or social dynamics within economic simulations. Such models underpin stock rebuilding strategies, ecosystem-based management and the evaluation of non-market benefits, guiding policy decisions that balance resource conservation with livelihoods and food security at local, regional and global scales.

Technical terms
Computable General Equilibrium (CGE) model: A multi-sectoral framework that simulates supply and demand balance across all markets, capturing price adjustments and policy shocks.
Input–Output (IO) model: A matrix representation of inter-industry transactions that quantifies how outputs of one sector serve as inputs to others.
Bioeconomic model: An integrative approach coupling population-level biological processes with economic decision-making to assess resource use and management outcomes.
Economic multiplier: A ratio that measures the total economic output generated per unit of direct spending, reflecting indirect and induced effects.
