Molecular assessment of parasite infection within socioeconomically important UK salmonid populations
Salmo trutta (Brown trout) is a native salmonid species to the United Kingdom. The economy generated via fish farming and eco-tourism has aided isolated communities in job creation and tourism income. It is particular true in highland communities in Scotland, where parasite infection has threatened …

Bacterial Kidney Disease and Its effect on the Salmonid Immune response
… agent of bacterial kidney disease (BKD) of salmonid fish, is a pathogen of great concern among fisheries and the aquaculture industry worldwide. Previous investigations have indicated the pathogenesis of BKD is complex. It is a chronic, multisystemic, granulomatous disease with a number of …

Effective Mitigation of Sedimentation on Riparian Riverbeds and Salmonid Populations After Dam Removal
… connectivity is especially important for salmonid populations, which and rely on longitudinal connectivity to reach spawning habitat. Dams prevent longitudinal connectivity while providing cities with potable water, hydroelectricity, and irrigation. With increasing knowledge of how dams …

History, Ecology and Restoration Potential of Salmonid Fishes in the Umpqua River, Oregon
Salmonid populations are decreasing across their historic range in the Pacific Northwest, and throughout the lower 48 states. This study incorporates a retrospective analysis of historical literature, traditional ecological knowledge as well as current ecology to determine historic salmonid …

Predation, turbidity, and other factors influencing juvenile Salmonid survival in the lower Snake River
… was to quantify consumption rates of juvenile salmonids by three introduced species, smallmouth bass (Micropterus dolomieu), walleye (Sander vitreus) and channel catfish (Ictalurus punctatus). Consumption information is crucial because the construction of the Snake River hydrosystem has created …

Associated behavioral, genetic, and gene expression variation with alternative life history tactics in salmonid fishes
… aimed at conserving life history variation among salmonids.</p>

Predicting salmonid population ecology from individual fish responses to environmental changes: bridging behaviour, conservation and fisheries management.
… and ecologically important chalk stream salmonid populations fail to incorporate fish behaviour and the interactions between fish with their environment and this limits their ability predicting management-relevant salmonid population responses to environmental change. A salmonid …

Influence of physical and biological habitat variables on juvenile salmonid and invertebrate drift abundance in southwest British Columbia streams
… that influence the abundance of juvenile salmonids in British Columbia streams will improve management practices. Habitat models are tools that provide insight into organisms’ habitat needs and provide a more efficient mechanism for estimating population abundance than direct measurement. …

A Case Study of Northern California: An Evaluation of Stream Restoration and the Success of Increasing California's Native Salmonid Stocks
… increasing populations of California’s Native Salmonid stocks. The case study identified the gaps in stream restoration projects as lacking standardization, and sustainable funding for the maintaining, monitoring and data collection that is needed post-implementation. The methods used were a …

Salmonids in an Urban Stream: Movement, Habitat, and Potential Barriers
Studies on the movement of salmonids in the Pacific Northwest have been vital to their management and recovery. Salmonids can move great distances in search of food, habitat and potential mates, requiring them to travel through a range of different habitat types. Altered and degraded streams may …

EVALUATION AND APPLICATION OF POPULATION SIZE ESTIMATORS TO ASSESS BROOK TROUT (SALVELINUS FONTINALIS) RESPONSE TO A NON-NATIVE SALMONID REMOVAL IN A SMALL MICHIGAN COLDWATER STREAM
<p>Non-native salmonids have been stocked into the Great Lakes since the 1870s and now naturalized populations use tributary environments to reproduce and for their juvenile life stage. Historically, brook trout were the only salmonid to inhabit the tributary environment and numerous studies …

The welfare and quality of farmed salmonids at harvest.
Salmonid farming has become a firmly established industry within the UK. To maintain or expand current markets the industry needs to produce high quality fish by humane and environmentally sustainable methods. This study examined the effects of harvesting on the stress response and carcass quality …

Implications of small-scale run-of-river hydropower schemes on fish populations in Scottish streams
… and other biota as significant, particularly on salmonid fish populations in relation to migration.This study investigated the implications of small-scale run-of-river hydropower schemes on fish populations in Scottish streams. In these schemes, water is abstracted from an intake above a mall …

AMPHIPODS ARE STRONG INTERACTORS IN THE FOOD WEB OF A BROWN-WATER SALMON RIVER
… which links dead spawner biomass to juvenile salmonid growth. We found that A. kygi had a complex life cycle with anadromous and resident forms. A. kygi dominated the macro-benthos, comprising more than 88.0% (SE=.01, N=7) of invertebrate biomass, and were highly mobile within the system, …
