“…Differences in the composition of sessile fauna between the two substrates can probably be attributed to the different degree of maturity of the communities under the cages when compared to that on the vertical collectors. In the first case, the high number of bryozoans and especially of poriferans, the latter uncommon in the fouling communities of Mar Grande of Taranto (Giangrande et al, 2021c), attested to the advanced stage of the assemblage on the artificial hard substrates under the cages; while the only sponge P. magna, together with the typical fouling elements C. coriacea and S. ciliatum (Longo et al, 2004;Longo and Pronzato, 2011), highlighted the early stage of developing community on the vertical collectors. Indeed, the immersion time of vertical collectors placed during the activity of the Remedia Life is certainly shorter than that of the substrates present under the cages.…”

“…More artificial structures mimicking natural reefs could be added under the cages, providing new habitats suitable for a rich benthic assemblage development. The restoration associated with aquaculture involving the use of artificial structures is an extension of the pioneer concept of the artificial reefs (Relini et al, 2007(Relini et al, , 2012 and represents a new application of the artificial structure philosophy (Giangrande et al, 2021c). The original purposes of the artificial reefs were the enhancement of fishery and the improvement of coastal management, as the protection of the seabed from illegal fishing and the increase of wild fish populations (Bombace et al, 1994;Relini et al, 2012).…”

The biodiversity of macrobenthic invertebrates of two artificial hard substrates close to a mariculture plant was assessed in order to understand the effect on the fouling community of an innovative Integrated Multi-Trophic Aquaculture (IMTA) system. The examined hard substrates were (i) vertical bare collectors that are placed around the cages as new colonizable substrates, which were investigated from the early colonization and (ii) artificial hard substrates already present under the cages analyzed over time to observe changes due to the action on the water column by filter feeder organisms colonizing the above vertical collectors. Overall, 186 taxa were collected (both the substrates), of which 99 as sessile habitat-former or structuring macroinvertebrates and 87 as associated fauna, mostly vagile forms. On the vertical collectors 121 taxa were collected, among which 44 sessile structuring species and 77 vagile-associated taxa; on the artificial hard substrates under the cages, 124 taxa were identified, 95 belong to the first category and 29 as associated taxa. The two analyzed substrates shared 43% of sessile species (40) and 22% of associated species (19). At the end of the first year of experimentation, the study revealed Sabella spallanzanii and mussels as the most abundant taxa. Lastly, the communities under the cages showed an increase in biodiversity after the placement of collectors. The changes were attributed to the decrease in particulate matter originating as wastes from the breeding cage, which was intercepted by the filter feeder community developed on the vertical collectors.

“…Besides aquaculture substrates, several studies have been carried out in other anthropogenic structures, namely ports and recreational marinas, to assess the distribution and diversity of NIS [26][27][28], as these structures play an important role as main hubs for the introduction of NIS via the maritime transport [29][30][31]. Recently, Giangrande et al [32] analyzed and compared the fouling communities found on several artificial substrates, including pontoons, quays, and ropes of a fish aquaculture facility of an enclosed part of the Mar Grande of Taranto (Ionian Sea). The authors concluded that the assemblages differed according to the age and size of the substrate, but also to their distance and depth from the fish aquaculture facility, as a proxy of organic enrichment.…”

Globally, there is growing concern regarding the effects of the increasing anthropogenic pressures in marine communities. Artificial structures such as marinas and aquaculture facilities serve as invasion hotspots; hence, monitoring fouling communities on these structures can be valuable for detecting new invasions. In the current study, 24 settlement PVC plates were deployed for three months to compare the recruitment ability of these two artificial environments along the south coast of the offshore island of Madeira (NE Atlantic). The results showed higher variations in the species richness between regions (SW vs. SE) than between artificial habitats (sea-cages vs. marinas), although the community composition differed. Cnidaria and Bryozoa were the most representative groups in the aquaculture systems, while Bryozoa and Chordata were in the marinas. A sum of 18 NIS was recorded for the study, accounting for between 21.88% and 54.84% of the total number of species in the aquaculture facilities and marinas, respectively. The higher NIS percentage from the marinas was even more explicit in the SE coast, where Cradoscrupocellaria bertholletii, Parasmittina alba, and Botrylloides niger distinctly dominated fouling populations. The results suggest that at least some particular NIS previously reported in the studied marinas successfully colonized sea-cages. Future assessments need to address the potential role of aquaculture facilities as drivers for the secondary spread of NIS. Additionally, two new records are considered for Madeira: Eudendrium capillare and Ericthonius punctatus.
