F I G U R E 4 in The future of fish-based ecological assessment of European rivers: from traditional EU Water Framework Directive compliant methods to eDNA metabarcoding-based approaches
F I G U R E 4 Boxplots (, median value;, interquartile range;, full range;, outliers) showing the variability in the eDNAadapted fish index (six metrics) computed at three sites (Brangues, Rhins and Usses) where 10 eDNA water samples were collected once. At each site, the eDNA-based six-metric fish index was computed for each of the 45 possible pairs of samples
F I G U R E 2 in The future of fish-based ecological assessment of European rivers: from traditional EU Water Framework Directive compliant methods to eDNA metabarcoding-based approaches
F I G U R E 2 Comparison of trait-based metrics expressed in number of species computed from eDNA () and traditional electrofishing (TEF;) samples in the five river stretches (RS), A, B, C, D and E. Trait categories: BEN, benthic; EUR, eurytopic; INS, insectivorous; OMN, omnivorous; PHY, phytophilic; POT, potamodromous; RHE, rheophilic; TOL, tolerant; PEL pelagic. Significance of the differences between eDNA and TEF metrics are shown: P <0.05; P <0.01; ns, not significant (P> 0.05)
F I G U R E 1 in The future of fish-based ecological assessment of European rivers: from traditional EU Water Framework Directive compliant methods to eDNA metabarcoding-based approaches
F I G U R E 1 Sampling locations along river stretches (RS) A to E () of the main channel of the Rhône River, France, using both traditional electro-fishing (TEF) and eDNA., Sites sampled every 2 months (September 2015– August 2016);, sites where ten eDNA water samples (filtration capsules) were collected once;, sites located on the tributaries or the Rhône River itself sampled once for eDNA. The 10 metric fish index and the adapted six-metric fish index were computed at all sites with a black filled symbol within natural water bodies

F I G U R E 3 in Three-dimensional migratory behaviour of European silver eels (Anguilla anguilla) approaching a hydropower plant
F I G U R E 3 Schematics of a river cross-section: (a) natural model and (b) rectangular model. Relative depth is defined as zrel ¼ z=d and relative width as Wrel ¼ x=W, where W is the river width and d is the local depth

F I G U R E 9 in Three-dimensional migratory behaviour of European silver eels (Anguilla anguilla) approaching a hydropower plant
F I G U R E 9 Distribution of first observations of eels closer than 3 m from bar rack at Herting hydropower plant: (a) horizontal distribution and (b) vertical distribution. Distributions are based on 41 observed interactions with the bar rack
F I G U R E 2 in Three-dimensional migratory behaviour of European silver eels (Anguilla anguilla) approaching a hydropower plant
F I G U R E 2 (a) The intake site at the Herting hydropower plant with migration routes available during the study period: a full-depth bypass next to the H1 powerplant and concrete weirs with a nature-like fishway. Location of hydrophones are shown in red. Areas to be analysed are denoted by blue dashed lines. (b) Detailed sketch of the angled rack and bypass at powerhouse H1

F I G U R E 1 Map of Sweden and the Ätran catchment, showing dams with or without fish passage solutions
F I G U R E 6 in Three-dimensional migratory behaviour of European silver eels (Anguilla anguilla) approaching a hydropower plant
F I G U R E 6 Correlation between relative swimming depths and inflow discharge for upstream- and downstream-swimming eels during the day and night in the river reach. Solid lines represent significant relationships, broken lines insignificant ones. Situation:, downstream day;, downstream night;, upstream day;, upstream night
