A Process Based Modeling Approach to Assess Temperature Impacts of Riparian Vegetation Management in a Southwestern Wisconsin Trout Stream

River Research and Applications, EarlyView.
ABSTRACT Rising water temperatures driven by climate change threaten culturally and economically important salmonid fisheries throughout the Upper Midwest. Unsuitable thermal regimes degrade the effectiveness of habitat restoration projects in the region, thus strategies for mitigating peak summer stream temperatures are of interest to state and non ...

Genome-Wide Association Analysis With a 50K Transcribed Gene SNP-Chip Identifies QTL Affecting Muscle Yield in Rainbow Trout

Frontiers in Genetics, 2018
Detection of coding/functional SNPs that change the biological function of a gene may lead to identification of putative causative alleles within QTL regions and discovery of genetic markers with large effects on phenotypes.

Postprandial Regulation of Hepatic MicroRNAs Predicted to Target the Insulin Pathway in Rainbow Trout

PLoS ONE, 2012
Rainbow trout are carnivorous fish and poor metabolizers of carbohydrates, which established this species as a model organism to study the comparative physiology of insulin.

Navigating Shallow Streams: Effects of Changing Stream Water Depths on Outmigration of Endangered Coho Salmon

River Research and Applications, EarlyView.
ABSTRACT Declining streamflow from water management and climate change threatens fish migration. In coastal California, USA, we evaluated the effects of receding streamflow on the seaward migration of juvenile Coho Salmon (Oncorhynchus kisutch) in four streams over 10 years (2010–2020).

Estrogen-like activity of perfluoroalkyl acids in vivo and interaction with human and rainbow trout estrogen receptors in vitro.

Toxicological Sciences, 2011
The objectives of this study were to determine the structural characteristics of perfluoroalkyl acids (PFAAs) that confer estrogen-like activity in vivo using juvenile rainbow trout (Oncorhynchus mykiss) as an animal model and to determine whether these ...

Instream Large Wood Enhances the Benefits of e‐Floods in Regulated Mountain Rivers

River Research and Applications, EarlyView.
ABSTRACT Environmental high flows, or e‐floods, released from dams are a key management strategy to mitigate the impacts of dam regulation and restore aquatic and riparian habitats. While there is extensive literature on the design and implementation of e‐floods, the role of instream large wood—downed trees, trunks, branches, and root wads—in enhancing

Geomorphic Reach Scale Controls the Availability of Brown Trout Spawning Sites in Große Mühl, An Alpine River of the Bohemian Massif

River Research and Applications, EarlyView.
ABSTRACT Studies on the quantity and quality of the spawning habitats of resident brown trout on the catchment scale of rivers are rare. The spawning habitats of salmonids are locally nested along river corridors and are found throughout variable channel patterns, with a preference for sediments composed of gravel and cobbles and appropriate flow ...

Capacité de la méthode des microhabitats à prédire l'habitat de reproduction de la truite commune

Knowledge and Management of Aquatic Ecosystems, 1995
La méthode des microhabitats a été appliquée pour le stade reproduction de la truite commune sur 205 faciès d'écoulement, appartenant à 6 rivières des Pyrénées centrales. La relation entre Surface Pondérée Utile (SPU) et densité de frayères est meilleure

Probiotic applications for rainbow trout (Oncorhynchus mykiss Walbaum) II. Effects on growth performance, feed utilization, intestinal microbiota and related health criteria postantibiotic treatment

, 2010
The effect of dietary probiotics (Bacillus subtilis, Bacillus licheniformis and Enterococcus faecium) was assessed on rainbow trout (Oncorhynchus mykiss Walbaum) previously treated with oxolinic acid.

Coral reef fish visual adaptations to a changing world

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Coral reef ecosystems show fluctuations in their prevailing light environment in response to both regular (e.g. between seasons) and more prevalent stochastic events (e.g. human‐induced sediment runoff).
