  abstract = {{W}e present a mathematical model of artificial pelagic multisite fisheries. {T}he model is a stock-effort dynamical model of a fishery subdivided into artificial fishing sites such as fish-aggregating devices ({FAD}s) or artificial habitats ({AH}s). {T}he objective of the work is to investigate the effects of the number of sites on the global activity of the fishery. {W}e consider a linear chain of fishing sites in which fish are harvested by fishing vessels and a free stock that is unattached to the sites and not exploited. {F}ish movements between the sites and the free stock, as well as vessel displacements between the sites, are assumed to take place at a faster time scale than the variation of the stock and the change of the fleet size. {W}e take advantage of these two time scales to derive a reduced model governing the dynamics of the total fish stock and the total fishing effort. {W}e show that there exists an optimal number of fishing sites that maximizes the total catch at equilibrium. {W}e finally extend the model to the situation in which both fish attached to the sites and fish in the free stock are exploited.},
