A few months later, the starfish Marthasterias glacialis was seen preying on the remaining oysters (Fig. 4). Seventy to eighty percent of the oysters that settled were killed by this combined predation. Buckley and Hueckel (1985) reported this type of predation pressure on barnacles by E. troschelii. The bivalve Mytilus galloprovincialis had settled and was observed on the 9 m reef in January 1994. This is a space-dominating species and it was expected that it would cover all reef surfaces, replacing the slowly decreasing Ostrea edulis population in the following few months.

93 Months Figure 3. ) reefs. , 1989). Examination of the feeding regime of species found on the reefs shows that 80% of the species described were carnivores, the other 20% herbivores. Bohnsack et aZ. (1991) reported that carnivores tend to dominate the nektonic biomass on marine artificial habitats and that herbivores may be limited by the restricted food resource. The fact that Posidonia beds surrounding the reefs are good feeding areas for herbivorous species must not be overlooked. Targeted commercial fish species such as ObZada me/anura and Diplodus sargus were not observed on either of the artificial reefs but were present on a natural reef 200 m away.
