Sources and impacts of inorganic and organic fine sediment in salmonid spawning gravels in chalk rivers

, 2012
Poor salmonid spawning habitat due to excessive fine sediment inputs has been identified as a major factor limiting survival in chalk rivers. A lack of knowledge about the complex processes and factors affecting survival was the driver for this study and

Landscape, demographic, and dispersal parameters influence the spread and establishment of an aquatic biological invasion

Ecosphere
Human‐mediated species introductions are contributing to the biotic homogenization of global flora and fauna. Despite extensive research, we lack simple methods of predicting how and where an introduced species will spread and establish, particularly in ...

Effects of domestication and captive breeding on reaction to moving objects: implications for avoidance behaviours of masu salmon Oncorhynchus masou

Royal Society Open Science, 2023
Domestication and captive breeding can compromise the obstacle- and predator-avoidance capabilities of animals in the wild. Whereas previous studies only examined these effects in combination, here we examine them individually by comparing the abilities ...

Short‐Term 6PPD‐Q Exposure alters Tight‐Junction‐Related Gene Expression Without Acute Lethality in Japanese Medaka Oryzias latipes

Journal of Applied Toxicology, EarlyView.
ABSTRACT 6PPD‐quinone (6PPD‐Q), a transformation product of the tire antioxidant 6PPD, causes acute mortality in several salmonid species, but its toxicity varies markedly among fish species. Disruption of vascular‐barrier integrity and inflammatory signaling has been proposed as a key mechanism of 6PPD‐Q toxicity.

Stream Temperature, Density Dependence, Catchment Size, and Physical Habitat: Understanding Salmonid Size Variation Across Small Streams

Fishes
The average body size (fork length) of juvenile salmonids in small streams varies across landscapes and can be influenced by stream temperature, density dependence, catchment size, and physical habitat. In this study, we compared sets of 16 mixed-effects

Transcriptomic and Histopathological Effects of Bifenthrin to the Brain of Juvenile Rainbow Trout (Oncorhynchus mykiss)

Toxics, 2021
The increased global use of pyrethroids raises concern for non-target aquatic species. Bifenthrin, among the most predominantly detected pyrethroids in the environment, is frequently measured in water samples above concentrations reported to induce ...

Overview of the re‐evaluation of trace elements as nutritional feed additives in the European Union: characterization, safety, and efficacy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The re‐evaluation of feed additives in the European Union was outlined in the Regulation (EC) No 1831/2003. The primary objectives were to ensure safety and verify efficacy, as well as to update authorizations and phase out unsafe additives or those in which the industry expressed no interest.
