Abstract

This paper studies the implications of fi sh search activities on the working of fisheries. We develop a simple shery matching model in 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 derived from their individual pro t maximizing behavior. Anthropic pressure determines 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 the ability of the model to reproduce empirical data.
