“…Fouling organisms related to aquaculture facilities such as the non-indigenous P. magna are in agreement with studies developed in the Mediterranean Sea [9,28,69], where it is considered a potential invasive species [70]. The relation of E. crocea with aquaculture activities has been also documented in other areas of the globe, namely Australia, where it can produce adverse effects [71].…”

“…Hence, our results suggest that, at least for some particular NIS, the presence of sea-cages could promote the secondary spread from the hotspots of introduction (i.e., marinas/ports). Future assessments would need to address the potential role of aquaculture facilities as drivers during the introduced NIS invasion process, similarly to studies performed in other basins [9,88,89].…”

“…Marine fish aquaculture operations consist of various floating and submerged structures (i.e., platforms, circular plastic rings, buoys, ropes, and nets), mainly classified as artificial polymer materials, which also serve as surfaces for biofouling colonization and settlement [5]. Biofouling on these artificial habitats is one of the main barriers to efficient and sustainable production [6,7], involving negative impacts (e.g., increasing drag forces on fish cages and restricting the water exchange through nets that could compromise the fish behavior and health) [8,9] with additional economic costs to the industry [10]. Moreover, fouling species in aquaculture cages may serve as a supplementary food source for the cultured fish and farm-associated species, stimulating the inspection and bites on the net that can lead on to more significant damages, such as escapes [11,12].…”

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.

“…In the planning of IMTA systems, profound knowledge of the environmental and biological characteristics of the area is required [102][103][104][105][106]. The biological characteristics of the local communities are not to be underestimated because their structure and dynamics are linked to the success of the polyculture.…”

In this paper, the different possibilities and innovations related to sustainable aquaculture in the Mediterranean area are discussed, while different maricultural methods, and the role of Integrated Multi-Trophic Aquaculture (IMTA) in supporting the exploitation of the ocean’s resources, are also reviewed. IMTA, and mariculture in general, when carefully planned, can be suitable for environmental restoration and conservation purposes. Aquaculture, especially mariculture, is a sector that is progressively increasing in parallel with the increase in human needs; however, several problems still affect its development, mainly in relation to the choice of suitable sites, fodder production, and the impact on the surrounding environment. A current challenge that requires suitable solutions is the implementation of IMTA. Unfortunately, some criticisms still affect this approach, mostly concerning the commercialization of new products such as invertebrates and seaweeds, notwithstanding their environmentally friendly character. Regarding the location of a suitable site, mariculture plans are currently displaced from inshore to offshore, with the aim of reducing the competition for space with other human activities carried out within coastal waters. Moreover, in open water, waste loading does not appear to be a problem, but high-energy waters increase maintenance costs. Some suggestions are given for developing sustainable mariculture in the Mediterranean area, where IMTA is in its infancy and where the scarce nutrients that characterize offshore waters are not suitable for the farming of both filter feeder invertebrates and macroalgae. From the perspective of coupling mariculture activity with restoration ecology, the practices suggested in this review concern the implementation of inshore IMTA, creating artificially controlled gardens, as well as offshore mussel farming coupled with artificial reefs, while also hypothesizing the possibility of the use of artificially eutrophized areas.

“…For this purpose, in recent decades, there has been an increasing interest in promoting the growth of biofouling on devoted artificial structures [6,[18][19][20][21][22][23][24][25][26][27][28]. Considering the extreme spatial and temporal variability of fouling, to reach good performances, the planned system should be based on knowledge of the environmental and biological characteristics of the area [29][30][31][32][33].…”

In this paper, we report data from the first year of rearing of a set of filter feeder bioremediator organisms: macrobenthic invertebrates (sabellid polychaetes and sponges), coupled with macroalgae, realized in a mariculture fish farm. This innovative integrated multi-trophic aquaculture (IMTA) system was realized at a preindustrial level in the Gulf of Taranto (southern Italy, northern Ionian Sea), within the framework of the EU Remedia Life project. Long lines containing different collector typologies were placed around the fish breeding cages. Vertical collectors were utilized for both polychaetes and sponges, whilst macroalgae were cultivated in horizontal collectors. Data on the growth and mortality of the target species after the first year of rearing and cultivation are given together with their biomass estimation. Polychaete biomass was obtained from natural settlement on ropes previously hung in the system, while sponges and macroalgae were derived from explants and/or inocules inserted in the collectors. The description of the successional pattern occurring on collectors used for settling until reaching a “stable” point is also described, with indications of additional filter feeder macroinvertebrates other than polychaetes and sponges that are easily obtainable and useful in the system as bioremediators as well. The results demonstrate an easy, natural obtaining of large biomass of sabellid polychaetes settling especially from about a 4 to 10 m depth. Sponges and macroalgae need to be periodically cleaned from the fouling covering. The macroalgae cycle was different from that of invertebrates and requires the cultivation of two different species with about a 6-month cycle for each one. The present study represents one of the first attempts at IMTA in the Mediterranean area where invertebrates and macroalgae are co-cultured in an inshore fish farm. Possible utilization of the produced biomass is also suggested.
