Abstract:
Many bioeconomy models of fisheries often do not take into account the evolution of the market price of landed stocks. However, it is a key variable in order to understand the sustainability of fishing activities, and allow to exhibit different long term behaviors for the resource evolution as well as for the fishing effort. We present a general fishing model that includes a model of price, demand and offer based on the classical theory of economy, which exhibit how the market can drive to either overexploitation or sustainability. We also present an example on how indirect policies (using Fish Agregation Devices) can allow fisheries to recover from overexploitation.
