Résumé

Fish face multiple environmental pressures acting as multiscale filters structuring the community [6]. Study of the effect of local (~100 m2) habitat components such as habitat architecture, substrate composition, and benthic community on fish community is still limited because of the technical difficulties to sample reliable descriptors of all these habitat components. Nevertheless, the effect of the 3D architecture, especially the complexity, has been highlighted to act as an important variable, locally structuring fish communities and leading to an increase in diversity (species richness and Shannon index) and quantity (total density and biomass) of fish [1]. Photogrammetry is extending to submarine environment and allows to produce very fine information of the architecture and substrate composition [5], as well as of the benthic community [4]. The influence of the different habitat components (i.e., architecture, substrate composition, and benthic community) on the structure of fish community is here investigated, as well as the interest of photogrammetry in comparison to visual observation (Fig. 1).
