“…Despite the implementation of the EU Water Framework Directive (2000/60/EC), the ecological status of natural water bodies requires a broader collection of information on the composition of the fish community. Reservoirs are considered widespread examples of heterogeneous aquatic ecosystems that are intermediate between rivers and lakes (Banerjee et al, 2017). Therefore, monitoring ecological indicators such as fish composition in reservoirs based on traditional sampling methods provides fragmented information and is challenging because they represent a transitional environmental system between lakes and rivers (Irz et al, 2002;Straškraba, 2005).…”

It is difficult to understand the composition and diversity of biological communities in complex and heterogeneous environments using traditional sampling methods. Recently, developments in environmental DNA metabarcoding have emerged as a powerful, non-invasive method for comprehensive community characterization and biodiversity monitoring in different types of aquatic ecosystems. In this study, water eDNA targeting fish (wf-eDNA) and four traditional fish sampling methods (electrofishing, gill netting, seining, trawling) were compared to evaluate the reliability and efficiency of wf-eDNA (vertebrate mitochondrial 12S ribosomal RNA (rRNA) as an alternative approach to assess the diversity and composition of freshwater fish communities. The results of wf-eDNA showed a consistency between the traditional sampling methods regarding species detection. However, some fish species detected using wf-eDNA assay were not detected using traditional sampling methods and vice versa. Comparison of wf-eDNA and traditional sampling methods revealed spatial homogeneity in fish community composition in all reservoirs. Ordination analysis showed that the wf-eDNA approach covers all traditional sampling methods and occupies an intermediate position. In addition, based on the Shannon diversity index, we found that in one reservoir the wf-eDNA method yielded similar fish community diversity to traditional sampling methods. However, in other reservoirs, the calculated Shannon diversity index of the wf-eDNA method was significantly higher than traditional sampling methods. In general, significant positive correlations were found between the wf-eDNA method and almost all traditional sampling methods. We conclude that wf-eDNA seems to be a reliable and complementary approach for biomonitoring and ecosystem management of freshwater ichthyofauna.

“…Ecologically, such order is extremely diverse presenting a large variety of morphological traits (Pagotto et al, 2011). To examine the changes caused by dams, several studies of freshwater drainage systems have been carried out around the world to gain a better understanding of the influence of these constructions on the fish community (Agostinho et al, 1997;Langeani et al, 2007;Miranda et al, 2008;Winemiller et al, 2016;Banerjee et al, 2017;Lin et. al., 2018).…”

ABSTRACT When a river is dammed, impacts differ according to distance from the dam under consideration, and sites closer to the dam are more affected than distant ones. Damming a river changes the flow and landscape characteristics, which, in turn, change the hydrological, limnological and ecological dynamics, such as biological production, species distribution, and ecosystem structuring, functioning and services. This study evaluates the distribution pattern of the Siluriformes (catfish) fish species near a small hydroelectric power plant in the Jaguariaíva River, considering three distinct distances from the dam: upstream region, reservoir and downstream region. Samples were taken with gillnets between March 2013 and December 2014. The abundance and richness of the Siluriformes species were evaluated. A permutational multivariate analysis of variance was used to access possible differences in species composition among sites. Finally, a permutational analysis of multivariate dispersion was used to assess possible differences among sampling sites and to examine composition similarities among sites. A total of 840 Siluriformes individuals were captured, distributed among ten species and four families. The highest richness was observed in the downstream region, while the lowest richness was observed in the reservoir area. Differences in the abundance of species were observed between the three distinct regions; the downstream region presented the highest species abundance (CPUE), whereas the lowest abundance was observed in the dam region. Hypostomus paulinus and Hypostomus strigaticeps were abundant species, but exclusively sampled in the downstream region, while Corydoras ehrhardti and Cambeva diabola presented their highest abundance in the upstream region. The distinct longitudinal distribution of Siluriformes observed in this study can be interpreted as indicative of the negative effects of damming. Our study suggests that building small dams may result in negative impacts on the fish assemblage, impacts comparable to those of large reservoirs in terms of spatial changes. It is fundamentally necessary to better evaluate the environmental impacts of small dams in the Neotropical region, especially because few is known about them and how such impacts are comparable to impacts of larger reservoirs.
