  abstract = {{U}nderstanding the ecological and anthropogenic drivers of population dynamics requires detailed studies on habitat selection and spatial distribution. {A}lthough small pelagic fish aggregate in large shoals and usually exhibit important spatial structure, their dynamics in time and space remain unpredictable and challenging. {I}n the {G}ulf of {L}ions (north-western {M}editerranean), sardine and anchovy biomasses have declined over the past 5 years causing an important fishery crisis while sprat abundance rose. {A}pplying geostatistical tools on scientific acoustic surveys conducted in the {G}ulf of {L}ions, we investigated anchovy, sardine and sprat spatial distributions and structures over 10 years. {O}ur results show that sardines and sprats were more coastal than anchovies. {T}he spatial structure of the three species was fairly stable over time according to variogram outputs, while year-to-year variations in kriged maps highlighted substantial changes in their location. {S}upport for the {M}c{C}all's basin hypothesis (covariation of both population density and presence area with biomass) was found only in sprats, the most variable of the three species. {A}n innovative method to investigate species collocation at different scales revealed that globally the three species strongly overlap. {A}lthough species often co-occurred in terms of presence/absence, their biomass density differed at local scale, suggesting potential interspecific avoidance or different sensitivity to local environmental characteristics. {P}ersistent favourable areas were finally detected, but their environmental characteristics remain to be determined.},
