| Resumo: | The fish assemblage associated with an artificial reef composed of small blocks (12 m³) with high structural complexity set in a Posidonia oceanica (L) Delile, 1813 meadow has been studied for 2 years by means of visual censuses. The fish assemblage was dominated qualitatively by species with medium home ranges living; in the surrounding areas of the blocks (mainly Labridae species), and numerically by schooling mid water species. After 38 months of deployment the progressive colonisation of species living on the blocks and the surrounding areas was still ongoing. The colonisation process interacts with seasonal changes, and no clear variations in the fish community variables were observed. The type of block used and the situation of the reef seem inappropriate to the aims for which it was deployed. |
