Fish assemblages were evaluated at natural and artificial walls in a temperate estuary. Assemblages changed in the immediate vicinity of both natural and artificial walls. The size of the effect was proportional to the size of the wall. Differences between natural and artificial walls were detected but were not consistent. Walls appear to act as localised biodiversity “hotspots”.
