  abstract = {{A}nalogous to other top predators foraging on patchy resources, the spatial behaviour of fishers provides information on the spatial organization of fish. {F}ocusing on the {P}eruvian anchovy purse-seine fishery, vessel monitoring system data are used to describe fishing vessels' trajectories, and acoustic survey data to characterize anchovy spatial distribution. {V}essel trajectories were analysed in terms of move-length distribution, whereas fish distribution was characterized by spatial extent, concentration, and fractal dimension. {F}ishers perform {L}evy flights that can be characterized by a single statistic (mu); mu is significantly correlated with the fractal dimension of fish distribution. {I}t is argued that the {L}evy statistic is a good candidate for an ecosystem indicator that might contribute to realtime monitoring of ecosystems.
