  abstract = {{O}wing to difficulties in accessing the vast open ocean, the beta (beta) diversity of pelagic fish assemblages remains poorly studied. {W}e investigated the relationship between assemblage similarity and geographical distance between anchored fish aggregating devices ({FAD}s), sampled by standardised underwater visual censuses in three anchored {FAD} arrays in the {I}ndian {O}cean-at the {M}aldives, the {S}eychelles and {M}auritius. {T}he use of two complementary indices of beta-diversity, based on presence/absence data ({J}accard similarity coefficient) and abundance data ({B}ray-{C}urtis index), revealed that geographical distance between sampling sites (from 4 to 257 km) appeared to have no effect on the similarity of fish assemblages associated with {FAD}s within each array. {T}he results of this preliminary study question the generalisation of the paradigm of an increase in beta-diversity with geographic distance to the open-ocean fish community. {L}arge-scale studies using a variety of datasets should be conducted to further investigate patterns of beta-diversity in the open ocean.},
