  abstract = {{T}ropical marine ecosystems are highly biodiverse and provide resources for small-scale fisheries and tourism. {H}owever, precise information on fish spatial distribution is lacking, which limits our ability to reconcile exploitation and conservation. {W}e combined acoustics to video observations to provide a comprehensive description of fish distribution in a typical tropical environment, the {F}ernando de {N}oronha {A}rchipelago ({FNA}) off {N}ortheast {B}razil. {W}e identified and classified all acoustic echoes into ten fish assemblage and two triggerfish species. {T}his opened up the possibility to relate the different spatial patterns to a series of environmental factors and the level of protection. {W}e provide the first biomass estimation of the black triggerfish {M}elichthys niger, a key tropical player. {B}y comparing the effects of euphotic and mesophotic reefs we show that more than the depth, the most important feature is the topography with the shelf-break as the most important hotspot. {W}e also complete the portrait of the island mass effect revealing a clear spatial dissymmetry regarding fish distribution. {I}ndeed, while primary productivity is higher downstream, fish concentrate upstream. {T}he comprehensive fish distribution provided by our approach is directly usable to implement scientific-grounded {M}arine {S}patial {P}lanning.},
