Executive Summary Aim Environmental assessment of hydropower facilities commonly includes means of fish assem- blage impact metrics, as e.g. injuries or mortality. However, this hardly allows for conclusion at the population or community level. To overcome this significant knowledge gap and to enable more efficient assessments, this task aimed in developing a fish species classification system according to their species-specific sensitivity against mortality. As one result, most sensitive fish species were identified as suitable candidates for in depth population effects and impact studies. Another objective was providing the biological and autecological baseline for developing a fish population hazard index for the European fish fauna. Methods The literature has been extensively reviewed and analysed for life history traits of fish providing resilience against and recovery from natural disturbances. The concept behind is that species used to cope with high natural mortality have evolved buffer mechanisms against, which might also foster recovery from human induced disturbances.

  • Beyond Fish Edna Metabarcoding: Field Replicates Disproportionately Improve the Detection of Stream Associated Vertebrate Species

Recent work on fish environmental DNA (eDNA) metabarcoding shows that aquatic diversity can be captured fast, reliably, and non-invasively at moderate costs. Because water in a catchment flows to the lowest point in the landscape, often a stream, it can col- lect traces of terrestrial species via surface or subsurface runoff along its way or when specimens come into direct contact with water (e.g., when drinking). Thus, fish eDNA metabarcoding data can provide information on fish but also on other vertebrate species that live in riparian habitats. This additional data may offer a much more comprehensive approach for assessing vertebrate diversity at no additional costs. Studies on how the sampling strategy affects species detection especially of stream-associated communities, however, are scarce. We therefore performed an analysis on the effects of biological replication on both fish as well as (semi-)terrestrial species detection.

Mercury content was higher in the muscles than other organs in both species (p < 0.05). Mercury accumulates along the food chain of the lake’s ecosystem. The value of the bioconcentration factor (BCF) indicated that Hg had accumulated in the highest amounts in muscles and in the other organs as follows: muscles > liver > gills > gonads.
