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 ...

Evaluation of tire tread particle toxicity to fish using rainbow trout cell lines

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

Tire and road wear particles (TRWP) resulting from tire abrasion while driving raise concerns due to their potential contribution to aquatic toxicity. Our study aimed to assess cryogenically milled tire tread (CMTT) particle toxicity, used as a proxy for T ...

The Bioaccumulation of Ionizable Organic Compounds in Fish Cell Lines

Fabian Gerhard Peter Balk

Bioaccumulation is defined as the enrichment of a compound in an organism relative to the surrounding water or its food, and is an important endpoint in chemical risk assessment. Under laboratory conditions, bioaccumulation is measured as bioconcentration ...

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 acute toxicity assessment of tire tread particles using rainbow trout cell lines of gill and intestine

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

Tire and road wear particles (TRWP) are generated by the abrasion of tires while driving, and recent questions were raised in regards to their potential contribution to microplastics released into the aquatic environment and their potential toxicological i ...

New Stable Cell Lines Derived from the Proximal and Distal Intestine of Rainbow Trout (Oncorhynchus mykiss) Retain Several Properties Observed In Vivo

Kristin Schirmer

We derived two novel cell lines from rainbow trout (RT) proximal (RTpi-MI) and distal intestine (RTdi-MI) and compared them with the previously established continuous cell line RTgutGC. Intestinal stem cells, differentiating and differentiated epithelial c ...

A ribonucleoprotein transfection strategy for CRISPR/Cas9-mediated gene editing and single cell cloning in rainbow trout cells

Kristin Schirmer

Background The advent of the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology marked the beginning of a new era in the field of molecular biology, allowing the efficient and precise creation of targeted mutations in the ge ...

Extending the Concept of Predicting Fish Acute Toxicity In Vitro to the Intestinal Cell Line RTgutGC

Kristin Schirmer, Hannah Inka Schug, Jenny Maner

Testing chemicals for fish acute toxicity is a legal requirement in many countries as part of environmental risk assessment. To reduce the number of fish used, substantial efforts have been focused on alternative approaches. Prominently, the cell viability ...

Bio-Inspired Tensegrity Fish Robot

Dario Floreano, Jun Shintake, Davide Zappetti, Timothée John Martin Peter, Yusuke Ikemoto

This paper presents a method to create fish-like robots with tensegrity systems and describes a prototype modeled on the body shape of the rainbow trout with a length of 400 mm and a mass of 102 g that is driven by a waterproof servomotor. The structure of ...
