Organ-specific biotransformation in salmonids: Insight into intrinsic enzyme activity and biotransformation of three micropollutants

Aquatic ecosystems continue to be threatened by chemical pollution. To what extent organisms are able to cope with chemical exposure depends on their ability to display mechanisms of defense across different organs. Among these mechanisms, biotransformatio ...

Effects of water releases and sediment supply on a residual flow reach

Giovanni De Cesare, Robin Schroff, Camille Blanck

An artificial floods program has been implemented on the Sarine residual flow reach, downstream of the Rossens dam. Two artificial floods were released in 2016 (coupled with sediment augmentation) and in 2020. A natural flood occurred in 2021. The indicato ...

Wirkungskontrolle einer Sedimentzugabe: Habitatvielfalt und Kolmation

Giovanni De Cesare, Christian Mörtl, Robin Schroff

In einer Restwasserstrecke der Saane wurde 2016 zur Sanierung der kolmatierten Gewässersohle und zur Aufwertung der Lebensräume ein künstliches Hochwasser ausgelöst und mit einer Sedimentzugabe gekoppelt. Die mittelfristigen Wirkungen der Sedimentzugabe wu ...

In Vitro Digestion of Tire Particles in a Fish Model (Oncorhynchus mykiss): Solubilization Kinetics of Heavy Metals and Effects of Food Coingestion

Kristin Schirmer, Florian Frédéric Vincent Breider, Benoît Jean Dominique Ferrari, Thibault Béranger Masset

Tire and road wear particles (TRWP) have been shown to represent a large part of anthropogenic particles released into the environment. Nevertheless, the potential ecological risk of TRWP in the different environmental compartments and their potential toxi ...

Effects of altered river network connectivity on the distribution of Salmo trutta: Insights from a metapopulation model

Andrea Rinaldo, Enrico Bertuzzo, Luca Carraro, Alexia Maria Gonzalez Ferreras

Network connectivity is a key feature of rivers that affects patterns and processes in lotic ecosystems. Few studies have considered how changes in river reach connectivity might affect ecosystem attributes at a whole river network scale. The use of popula ...

Maternal allocation of carotenoids increases tolerance to bacterial infection in brown trout

Laure Menin, Daniel Ortiz Trujillo, Matay Hobil

Life-history theory predicts that iteroparous females allocate their resources differently among different breeding seasons depending on their residual reproductive value. In iteroparous salmonids there is typically much variation in egg size, egg number, ...

An epidemiological model for proliferative kidney disease in salmonid populations

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Luca Carraro, Marino Gatto

Background: Proliferative kidney disease (PKD) affects salmonid populations in European and North-American rivers. It is caused by the endoparasitic myxozoan Tetracapsuloides bryosalmonae, which exploits freshwater bryozoans and salmonids as hosts. Inciden ...

Attractiveness of a lateral shelter in a channel as a refuge for juvenile brown trout during hydropeaking

Anton Schleiss, Jean-Marc Ribi, Armin Julius Peter

Peak power production in hydroelectric storage power plants results in frequent and intense flow variations in the rivers downstream of the plants. Fish populations can be negatively impacted when subjected to these so-called hydropeaking phenomena. In res ...

Flow restoration in Alpine streams affected by hydropower operations—a case study for a compensation basin

Anton Schleiss, Martin Peter Bieri, Michael Müller

Hydropeaking, resulting from rapid starting and shut-down of turbines, is one of the major hydrological alterations in Alpine streams. The upper Aare River basin in Switzerland comprises a complex high-head storage hydropower scheme. The significant turbin ...

Mitigation measures for fish habitat improvement in Alpine rivers affected by hydropower operations

Anton Schleiss, Martin Peter Bieri, Émilie Person, Armin Julius Peter

In mountainous areas, high-head-storage hydropower plants produce peak load energy. The resulting unsteady water release to rivers, called hydropeaking, alters the natural flow regime. Mitigating the adverse impacts of hydropeaking on aquatic ecosystems ha ...
