The measurement of species diversity represents a powerful tool for assessing the impacts of human activities on marine ecosystems. Traditionally, the impact of fish farming on the coastal environment is evaluated by monitoring the dynamics of macrobenthic infaunal populations. However, taxonomic sorting and morphology-based identification of the macrobenthos demand highly trained specialists and are extremely time-consuming and costly, making it unsuitable for large-scale biomonitoring efforts involving numerous samples. Here, we propose to alleviate this laborious task by developing protist metabarcoding tools based on next-generation sequencing (NGS) of environmental DNA and RNA extracted from sediment samples. In this study, we analysed the response of benthic foraminiferal communities to the variation of environmental gradients associated with salmon farms in Scotland. We investigated the foraminiferal diversity based on ribosomal minibarcode sequences generated by the Illumina NGS technology. We compared the molecular data with morphospecies counts and with environmental gradients, including distance to cages and redox used as a proxy for sediment oxygenation. Our study revealed high variations between foraminiferal communities collected in the vicinity of fish farms and at distant locations. We found evidence for species richness decrease in impacted sites, especially visible in the RNA data. We also detected some candidate bioindicator foraminiferal species. Based on this proof-of-concept study, we conclude that NGS metabarcoding using foraminifera and other protists has potential to become a new tool for surveying the impact of aquaculture and other industrial activities in the marine environment.

“…However, the knowledge about the environmental impact is still scarce, especially for the Adriatic. The investigations mainly focused on changes of physical and chemical properties of water column and sediments (D'Agaro & Lanari ; Matijević, Kušpilić, Morović, Grbec, Bogner, Skejić & Veža ; Sangulin, Babin & Skrgatic ; Matašin, Oreščanin, Jukić, Nejedli, Matašin & Gajger ) and benthic organisms (Najdek, Travizi, Bogner & Blažina ; Fabi, Manoukian & Spagnolo ; Grego, De Troch, Forte & Malej ; Vidović, Cosović & Juračić ). However, only two studies to date explored the changes within phytoplankton communities near fish farms (Skejić, Marasović, Vidjak, Kušpilić, Ninčević, Šestanović & Bojanić ) and no study examined the effects of fish farming on the microbial components of plankton web.…”

Effects of fish farming on microbial planktonic communities in the middle Adriatic sea

The effects of farming on planktonic microbial communities were investigated at the coastal sea bass/sea bream farm in the oligotrophic middle Adriatic Sea. Analyses of nutrients, chlorophyll a, cyanobacteria (Prochlorococcus), heterotrophic bacteria and nanoflagellates (both pigmented and heterotrophic) were carried out on samples taken during six seasonal cruises at different water depths. Farming activity increased the natural concentrations of some nutrients (ammonium, nitrite, phosphate, dissolved inorganic nitrogen) and changed their seasonal pattern. The values still remained typical for oligotrophic environments demonstrating no risk for eutrophication. Enhanced nutrient supply provoked an immediate increase in abundances of both autotrophic and heterotrophic microbial groups (except pigmented nanoflagellates) and chlorophyll a. The effect of farming was more visible for the heterotrophic microbial component. Results from this study reveal a potential common pattern of microbial response to farming in the oligotrophic environments. It also suggests the importance of heterotrophic microbial web in transferring the matter and energy released from the fish farms in nutrient poor environments.

“…Differentiated species seem to be well adapted to the reduced oxygen availability in the sediment. The susceptibility of A. tepida and the genus Haynesina to environmental stress has been previously determined (ALMOGI-LABIN et al, 1992;DEBENAY et al, 2000;DEBENAY et al, 2001;DE-BENAY & GUILLOU, 2002;VIDOVIĆ et al, 2009). However, A. parkinsoniana is not considered to be a stress-tolerant species (VIDOVIĆ et al, 2014).…”

“…Recent foraminiferal studies along the eastern Adriatic coast have been mostly restricted to investigation of species distribution (VIDOVIĆ, 2010;ĆOSOVIĆ et al, 2011) and to the possible application of foraminifera as indicators of anthropogenic pollution (VIDOVIĆ et al, 2009;POPADIĆ et al, 2013;VIDOVIĆ et al, 2014). Only a few studies have focused on the determination of fauna inhabiting marginal marine environments and their dependence on environmental conditions, as well as their application in palaeoenvironmental reconstructions.…”
