“…These benthic sessile organisms can act as ecosystem engineers, creating biogenic habitats through the provision of an additional biofouling surface, shelter or food for associated flora and motile fauna (Roberts et al, 2008 and references therein). Moreover, macroinvertebrate fauna present in fouling are able to Fouling assemblages associated with off-coast aquaculture facilities: an overall assessment of the Mediterranean Sea assimilate the organic matter derived from coastal fish farms, reducing production waste and its accumulation on the seabed (Gonzalez-Silvera et al, 2015).

“…Published information on motile fauna associated with aquaculture fouling is still scarce. Several studies highlight the presence of amphipods, especially caprellids, occurring in high numbers and/or biomass in fish farms (Cook et al, 2006;Greene & Grizzle, 2007;Guenther et al, 2010;Fernandez-Gonzalez et al, 2014;Gonzalez-Silvera et al, 2015), but little is known about the species involved and their distribution, particularly in the Mediterranean Sea.…”

Aquaculture facilities provide a suitable habitat for a wide group of marine species that are able to colonise and settle on artificial structures. This study aims to determine the composition of fouling communities in off-coast facilities, with special emphasis on motile epifauna and amphipods as a main group. Seventeen aquaculture sites were sampled along the Mediterranean coast, collecting samples by scraping fouling organisms directly from the ropes. Additionally, thirty publications were reviewed, in order to assess the similarity of aquaculture fouling with other fouling communities. Our results reflect that amphipods accounted for more than 80% of the epifauna associated with farms fouling communities. This characteristic epifauna was defined by seven amphipod species well-adapted to colonise and survive in these off-coast habitats. Most species common in farms have also been commonly found in harbours, marinas, and/or offshore on turtles, buoys or platforms etc., showing a great resistance to polluted areas but also to dispersal via rafting on floating objects. In this study, two exotic species were identified: Caprella scaura and Stenothoe georgiana, the latter being the first report from the Mediterranean Sea. The presence of Jassa slatteryi was also confirmed, underestimated until now in the Mediterranean.

“…Macroinvertebrate species associated with fish farms have been shown to assimilate the organic matter derived of uneaten feed pellets and fish faeces [10], and tanaidaceans may also take advantage of this new trophic resource. Specifically, tanaidaceans represent between 0.03 and 15.9 % of the mobile epifauna associated with fish farms fouling in the Mediterranean Sea, being the third group in importance after amphipods and polychaetes [11].…”

An undescribed species of tanaidacean belonging to the genus Hexapleomera, tribe Pancolini, Hexapleomera bultidactyla sp. nov. was found in fouling community samples from off-coast fish farms cages in the western Mediterranean Sea. The species can be distinguished from other Hexapleomera species by the presence of a ventral apophysis on the dactylus of the chela in males. Other diagnostic characters (in combination) include a male antennule with five aesthetascs, the female with three, the maxillule palp with four terminal setae and maxilliped basis and coxa each with two setae; the male fixed finger with four ventral setae and proximal apophysis, the female chela fixed finger with a proximal triangular apophysis, an apophysis on the coxa of pereopod 1, a pleopod 3 basis with three outer setae, and an uropod of four segments. Although several substrata were investigated, the species was most abundant where the turf formed by Ceramiaceae algae and the hydroid Aglaophenia sp. was dominant. An updated identification key to all the species of Hexapleomera is provided.

Under natural conditions, Chroothece richteriana synthesizes a fairly high proportion of fatty acids. However, nothing is known about how environmental changes affect their production, or about the production of protective compounds, when colonies develop under full sunshine with high levels of UV radiation. In this study, wild colonies of C. richteriana were subjected to increasing temperature, conductivity, ammonium concentrations and photosynthetically active radiation (PAR), and UV radiations to assess the potential changes in lipid composition and mycosporine-like amino acids (MAAs) concentration. The PERMANOVA analysis detected no differences for the whole fatty acid profile among treatments, but the percentages of α-linolenic acid and total polyunsaturated fatty acids increased at the lowest assayed temperature. The percentages of linoleic and α-linolenic acids increased with lowering temperature. γ-linolenic and arachidonic acids decreased with increasing conductivity, and a high arachidonic acid concentration was related with increased conductivity. The samples exposed to UVB radiation showed higher percentages of eicosapentaenoic acid and total monounsaturated fatty acids, at the expense of saturated fatty acids. MAAs accumulation increased but not significantly at the lowest conductivity, and also with the highest PAR and UVR exposure, while ammonium and temperature had no effect. The observed changes are probably related with adaptations of both membrane fluidity to low temperature, and metabolism to protect cells against UV radiation damage. The results suggest the potential to change lipid composition and MAAs concentration in response to environmental stressful conditions due to climate change, and highlight the interest of the species in future research about the biotechnological production of both compound types.
