Stream Restoration for the Spawning of Trout: How to Enhance the Egg to Fry Survival and to Monitor the Spawning Efficiency?

River Research and Applications, EarlyView.
ABSTRACT Today, salmonid management is largely based on river restoration. One of the fundamental elements is the creation of functional spawning sites. Key values of sedimentological characteristics must be defined in terms of granulometry, permeability, and oxygen concentration to ensure the best possible success of the operations.

Fine Sediment Depositional Patterns and Fish Habitat Following Wildfire and Debris Flow

River Research and Applications, EarlyView.
ABSTRACT The 2020 Cameron Peak wildfire burned part of the Poudre River catchment in Colorado, USA. The river flows through a high‐gradient canyon before entering a lower‐gradient transition zone with modified channel morphology and flow regime. Widespread post‐fire erosion introduced fine sediment (< 2 mm) to the river, causing sediment deposition and

A synthetic rainbow trout linkage map provides new insights into the salmonid whole genome duplication and the conservation of synteny among teleosts

BMC Genetics, 2012
BackgroundRainbow trout is an economically important fish and a suitable experimental organism in many fields of biology including genome evolution, owing to the occurrence of a salmonid specific whole-genome duplication (4th WGD). Rainbow trout is among

Making Waves: The Effects of Whitewater Parks on Fish Passage in Colorado

River Research and Applications, EarlyView.
ABSTRACT Instream structures have fragmented riverine habitats throughout much of the world, including the Western USA. Whitewater parks (WWPs) are relatively new instream structures designed to create hydraulic waves for recreational boating and surfing by constricting flows into a steep chute or drop.

SIMULATING PROTEIN DIGESTION ON TROUT A RAPID AND INEXPENSIVE METHOD FOR DOCUMENTING FISH MEAL QUALITY AND SCREENING NOVEL PROTEIN SOURCES FOR USE IN AQUAFEEDS [PDF]

Croatian Journal of Fisheries, 1997
A novel in vitro digestion system, which simulated rainbow trout gastric and intestinal digestion was developed. The method was employed to evaluate the impact of the gastric phase of digestion upon degradation of three fish meals od differing quality ...

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.

Integrated Use of Oxidative Stress and Histological Biomarkers of T. tinca as Indicators of 17‐Alpha‐Ethynylestradiol Exposure

Environmental Toxicology, EarlyView.
ABSTRACT The potential adverse effects of 17‐alpha‐ethynylestradiol (50, 100, and 500 μg EE2/kg b.w., for 30 days) on tench (Tinca tinca) were evaluated by integrating biomarkers including physiological (hepato‐somatic index, spleen‐somatic index, and hematocrit), oxidative stress (catalase, glutathione peroxidase, and glutathione reductase activities;

Describing biological parameters of several endemic Salmo species from the Caspian Sea and Persian Gulf basins

Oceanological and Hydrobiological Studies
Salmonids are a crucial component in aquatic ecosystems due to their trophic roles in nutrient cycling. They are also significant sources of food and salmonid fisheries make important contributions to local economies, while also being of cultural and ...
