  abstract = {{P}redatory fishes, such as tunas, billfishes, and sharks, coexist in pelagic regions of the tropical oceans. {I}n situ experiments have revealed horizontal and vertical movement patterns for different pelagic species, but the influence of the biotic environment on movement behaviour has not been studied. {I}n this paper, we propose a simple model in which the movement behaviour of these fishes is driven entirely by the biotic environment, without implementing physiological constraints. {W}e explore this concept via computer simulations based on the {L}atent {E}nergy {E}nvironments model ({M}enczer, {F}., {B}elew, {R}.{K}., 1966a. {F}rom complex environments to complex behaviors. {A}dapt. {B}ehav. 4(3/4), 317-63). {I}n our model, multiple behaviours for artificial fishes evolve in a three-dimensional environment where spatial and temporal distributions of prey are patterned after hydroacoustic data taken during ultrasonic telemetry experiments on tunas in the open ocean in {F}rench {P}olynesia. {I}nteractions among indiviudals are modeled through their shared prey resources. {M}ovement patterns of the adapted individuals are analyzed to : (i) compare artificial individuals with real fishes (three species of tuna, three species of billfishes, and one species of shark) observed by ultrasonic telemetry ; and (ii) examine how the artificial fishes exploit their environment. {M}ost of the individuals evolved vertical patterns virtually identical to those exhibited by fishes in the wild. {T}he agreement between our simple model and the ethological data validates the use of computational models for studies of the characteristics of multiple species inhabiting a common ecosystem.
