HAL CCSD Résumé : This paper studies the implications of fi
sh search activities on the working of
fisheries. We develop a simple
shery matching modelin which
rms stochastic search for
sh requires speci
fic resources.The equilibrium level of anthropic pressure (number of empty ves-sels/conserved
sh stock) exerted by
rms on the
sh stock is derivedfrom their individual pro
t maximizing behavior. Anthropic pressuredetermines in turn the rate at which vessels fi
nd fi
sh i.e. catchability,which is therefore endogenous in our model, and the stock conserva-tion (uncaught
sh) rate, through the dynamic equation of the latter.We then show that under open access, equilibrium anthropic pressure,
fishing effort and the conservation rate heavily depend on search costs.An empirical study of the French Guiana shrimp
shery con
rms theability of the model to reproduce empirical data.
