. A Mediterranean fish assemblage has been visually censused over a period of two years from two permanent, rocky, infralittoral stations (10–15 m) which display a high habitat complexity and are located in a protected area. Six home‐range categories were defined for a better understanding of the community structure which was analyzed through qualitative and quantitative data. The respective roles of different sources of variability in species composition and numerical abundance were evaluated.
