  abstract = {{T}rawling pressure and environmental changes may affect the composition of fish assemblages. {O}ur knowledge on large spatio-temporal patterns of demersal fish composition remains incomplete for the {M}editerranean {S}ea. {W}e investigated (1) the spatio-temporal stability of demersal assemblages, (2) the relationships between these assemblages and potential structuring factors (trawling pressure and environmental conditions) in order to assess the dynamic of the assemblage structure at the scale of the northern {M}editerranean {S}ea. {W}e analysed a dataset of 18062 hauls from 10 to 800 m depth performed annually during the last two decades across 17 {G}eographical {S}ub-{A}reas ({GSA}s) ({MEDITS} program). {A} multi-table analysis ({STATICO}-{C}o{A}) evidenced a strong inter-{GSA}s stability in the organization of assemblages, with specificities for some {GSA}s. {T}he most stable structuring factors were linked to combined gradients of chlorophyll a, phytoplancton carbon biomass and temperature, inversely correlated with depth, salinity and nutrient gradients (axis 1 of the {STATICO}-{C}o{A} compromise, 93.74% of the total variability). {A} common pattern linking the distribution of species to these environmental gradients was evidenced for most of the 17 {GSA}s. {E}stimate of trawling pressure showed a minor role in the organization of the assemblages for the spatial scale and years investigated (axis 2. 4.67%).},
