MOESM1 of Movements of dead fish in rivers
Additional file 1. Groups of dead Atlantic salmon smolts and European silver eels tagged with radio transmitters and released in three German rivers. Information on fish taken by scavengers in these groups is also given. nd = not detected
MOESM4 of Movements of dead fish in rivers
Additional file 4. Downstream drift of individual dead European silver eels released in the Sieg (a) in the tailrace on 8 October 2014 (n = 5), (b) in the tailrace on 10 October 2015 (n = 10), (c) in the tailrace on 13 October 2015 (n = 10), and (d) in the tailrace (colored points) or spillway gate (colored triangles) 21 November 2015 (n = 10). The position of eels during each tracking survey or when they passed receiver sites are shown as individually colored points with lines between. The last registration of fish taken by a scavenger is marked with an S. Water discharge (black line) is also shown
MOESM3 of Movements of dead fish in rivers
Additional file 3. Downstream drift of individual dead Atlantic salmon smolts released (a) in the tailrace in the Sieg on 9 and 16 April (n = 20), (b) on the turbine in the Kinzig on 13 and 18 April (n = 20), and (c) in the Archimedes screw turbine in the Diemel on 10 and 15 April 2015 (n = 20). The position of smolts during each tracking survey or when they passed receiver sites are shown as individually colored points with lines between. The last registration of fish taken by a scavenger is marked with an S. Water discharge (black line) is also shown. Note that the scales on the y-axes differ
MOESM2 of Movements of dead fish in rivers
Additional file 2. Overview of manual tracking surveys for radio tagged dead Atlantic salmon smolts and European silver eels in three German rivers. Maximum distance surveyed during manual tracking downstream from the release site is given, but the entire distance was not tracked during all surveys. The positions of downstream stationary receivers are also given
MOESM5 of Movements of dead fish in rivers
Additional file 5. Downstream drift of individual dead European silver eels released (a) on the turbine in the Kinzig on 12 October and 21 November 2015 (n = 10), and (b) in the Archimedes screw turbine (colored points) and tailrace of a Francis turbine (colored triangles) in the Diemel on 9 October 2014 (n = 10). The position of eels during each tracking survey or when they passed receiver sites are shown as individually colored points with lines between. The last registration of fish taken by a scavenger is marked with an S. Water discharge (black line) is also shown. In the Kinzig, eels that drifted out of the tracked stretch and entered the Rhine is indicated with an R. In the Diemel, eels that disappeared from the river during the winter when monitoring was suspended are indicated with a U. Note that the scales on the y-axes differ
