  abstract = {{W}e conducted displacement experiments using acoustic tags to study the orientation abilities of dolphinfish ({C}oryphaena hippurus) around {FAD}s. {E}leven fish were passively monitored using coded transmitters and acoustic receivers attached to {FAD}s, while seven others were actively tracked with a vessel using continuous acoustic tags equipped with pressure sensors. {A}ll these 18 dolphinfish were captured close to a {FAD} and released between 70 and 1720 m from it. {F}ive fish out of the 14 that were displaced at more than 360 m from a {FAD} ( estimated detection range of our acoustic receivers, defining the target area during our experiment) returned to the target area. {W}ith one individual successfully returning to the target area after having been released at 1600 m from the {FAD}, the rate of return of fish released up to this distance was significantly higher than expected if they were moving at random, but many fish released at intermediate distances moved in other directions. {B}ased on detailed statistical analysis of the return score, we estimated that dolphinfish are able to orientate towards a {FAD} area from at least 820 m. {T}he connection between our definition of the target area and the association area of dolphinfish around a {FAD} is discussed, as well as the impact of stress and motivation in the rates of return observed. {M}ore experiments should be conducted to improve this first estimate. {S}pecific experiments should also be designed to more accurately determine the association range of fish around {FAD}s and their motivation to orientate towards {FAD}s.},
