Ciliates are powerful indicators for monitoring the impact of aquaculture and other industrial activities in the marine environment. Here, we tested the efficiency of four different genetic markers (V4 and V9 regions of the SSU rRNA gene, D1 and D2 regions of the LSU rRNA gene, obtained from environmental (e)DNA and environmental (e)RNA) of benthic ciliate communities for environmental monitoring. We obtained these genetic metabarcodes from sediment samples collected along a transect extending from below salmon cages toward the open sea. These data were compared to benchmark data from traditional macrofauna surveys of the same samples. In beta diversity analyses of ciliate community structures, the V4 and V9 markers had a higher resolution power for sampling sites with different degrees of organic enrichment compared to the D1 and D2 markers. The eDNA and eRNA V4 markers had a higher discriminatory power than the V9 markers. However, results obtained with the eDNA V9 marker corroborated better with the traditional macrofauna monitoring. This allows for a more direct comparison of ciliate metabarcoding with the traditional monitoring. We conclude that the ciliate eDNA V9 marker is the best choice for implementation in routine monitoring programs in marine aquaculture.

“…The diversity and community composition of forams are known to change with anthropogenic pollution, fish farming, and decreasing water quality (Damak, Frontalini, Elleuch, & Kallel, 2019; Frontalini & Coccioni, 2011; Pawlowski, Esling, Lejzerowicz, Cedhagen, & Wilding, 2014; Raposo et al., 2018; Uthicke & Nobes, 2008), and similar to nematodes, OC enrichment of the sediment also influences the diversity of forams (Alve et al., 2016; Martins et al., 2015; Murray, 2006). Ciliates are used as bioindicators in e.g., aquaculture (Stoeck, Kochems, Forster, Lejzerowicz, & Pawlowski, 2018), wastewater treatment plants, and monitoring of eutrophication and chemical pollution (Chen, Xu, Tam, Cheung, & Shin, 2008; Foissner, 2016; Pawlowski, Lejzerowicz, Apotheloz‐Perret‐Gentil, Visco, & Esling, 2016). In natural aquatic environments, the diversity and community composition of ciliates are influenced by e.g., salinity, pH, and anthropogenic pollution (e.g., Gong et al., 2015; Jiang, Xu, Hu, Warren, & Song, 2013).…”

“…Moreover, the protozoan community composition is sensitive to pollutants, and changes in protozoan diversity and community structure reflect changes in habitat quality (Foissner 1999). As a consequence, the community characteristics of benthic protozoa can serve as biological indicators of the environmental status of mangrove ecosystems (Chen et al 2008(Chen et al , 2009.…”

The protection and restoration of mangrove ecosystems depend on understanding the interaction between benthic organisms and mangrove succession. Although benthic protozoa are important in such ecosystems, protozoan community dynamics have seldom been studied during the mangrove succession. The benthic protozoa of a mangrove chronosequence that included a primary community (unvegetated shoal), an early community (Avicennia marina), a middle community (Aegiceras corniculatum), and a late community (Bruguiera gymnorrhiza + Rhizophora stylosa) were investigated to determine the changes in the benthic protozoan community during a mangrove succession at Zhanjiang, China. A total of 62 benthic protozoa taxa belonging to three classes, 26 orders, and 38 families were recorded. The abundance of benthic protozoa decreased significantly during mangrove succession, while species richness and diversity changed irregularly. Hierarchical clustering indicated that the distribution of the benthic protozoa closely corresponded with the mangrove successional stages. Further analyses indicated that the changes in the benthic protozoan community with mangrove succession were associated with the changes in total sediment nitrogen content and especially with vegetation characteristics, including plant height and crown breadth. The decline in the abundance of benthic protozoa during mangrove succession may be explained by the deterioration of benthic protozoan microhabitats. However, determining whether these or other factors are responsible for the change in the benthic protozoan community during mangrove succession will require additional research.
