Game Theory Applications in Fisheries Management

Game theory offers a powerful lens for understanding strategic interactions among fishers, regulators and other stakeholders in the management of common-pool marine resources. By modelling decisions as games, researchers can predict whether individual actors will cooperate to sustain fish stocks or pursue short-term gains that lead to overfishing. Key themes include the tragedy of the commons, where non-cooperative harvesting drives stocks to collapse; the design of enforcement and quota systems that shift equilibria towards compliance; and the role of uncertainty, information asymmetry and dynamic feedbacks in shaping strategic choice. Contemporary approaches integrate ecological dynamics—such as logistic growth and tipping points—with social perceptions and enforcement mechanisms, yielding insights into when punitive audits, quota transfers or cooperative agreements can stabilise harvests. These models inform policy by identifying governance structures that balance equity, efficiency and resilience across diverse fisheries worldwide.

A foundational study explores non-linear transition pathways in social-ecological systems by modelling fishers as interacting agents within a perception-exploitation framework. Game-theoretic analysis reveals that heightened collective awareness of declining stocks can deliver short-term ecological gains but may undermine long-term recovery if it induces overly cautious or opportunistic behaviour. The work highlights the importance of incorporating tipping-point dynamics into strategic decision models and provides a framework for anticipating regime shifts in fisheries under varying social perceptions.

Technical terms

Nash equilibrium: A set of strategies in which no player can improve their payoff by unilaterally deviating.

Tragedy of the commons: A scenario where individual users, acting independently according to their own self-interest, deplete a shared resource.

Subgame-perfect equilibrium: A refinement of Nash equilibrium for sequential games, requiring credible strategies in every possible subgame.

Tipping point: A threshold in a social-ecological system at which small changes trigger a rapid shift to a different regime.

Quota transfer: A policy tool allowing reallocation of fishing rights among parties to support cooperative and efficient resource use.
