Do non-native pumpkinseed Lepomis gibbosus affect the growth, diet and trophic niche breadth of native brown trout Salmo trutta?

Hydrobiologia, 2016
Brown trout Salmo trutta Linnaeus, 1758, is a priority species for conservation and management efforts in many European countries. In its native range, interactions with non-native fishes often adversely affect somatic growth rates and population ...

Selective Migration: Unravelling Phenotype‐Dependent Fishway Passage Success in Anadromous Three‐Spined Sticklebacks

River Research and Applications, EarlyView.
ABSTRACT Fishways mitigate barriers blocking fish migration, but their effectiveness varies among species. Whether passage success also varies among individuals of the same species based on their morphology, physiology, or behaviour is largely unknown, particularly for small species.

Seasonal effects of the fatty acid composition of phospholipid and triacylglycerol in the muscle and liver of male Salmo trutta macrostigma

Grasas y Aceites, 2021
The seasonal effects on the fatty acid composition of triacylglycerol (TAG) and phospholipid (PL) in the muscle and liver of male Salmo trutta macrostigma were determined using the gas chromatographic (GC) method.

Predicting presence and absence of trout (Salmo trutta) in Iran

Limnologica, 2014
Species distribution modelling, as a central issue in freshwater ecology, is an important tool for conservation and management of aquatic ecosystems. The brown trout (Salmo trutta) is a sensitive species which reacts to habitat changes induced by human impacts. Therefore, the identification of suitable habitats is essential.

Drift Foraging by Allopatric and Sympatric Atlantic Salmon and Brown Trout Parr Under Rapid Flow Fluctuations

River Research and Applications, EarlyView.
ABSTRACT Hydropeaking may result in behavioral responses in riverine organisms that experience rapid flow fluctuations. In stream fish, the balance between energy spent on swimming and foraging vs. food intake affects fitness, a balance strongly influenced by flow conditions.

Effects of Different Farming Modes on Salmo trutta fario Growth and Intestinal Microbial Community

Microorganisms
The gut microbiota plays a pivotal role in upholding intestinal health, fostering intestinal development, fortifying organisms against pathogen intrusion, regulating nutrient absorption, and managing the body’s lipid metabolism. However, the influence of

The Long and the Short of It: Nanopore‐Based eDNA Metabarcoding of Marine Vertebrates Works; Sensitivity and Species‐Level Assignment Depend on Amplicon Lengths

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT To monitor the effect of nature restoration projects in North Sea ecosystems, accurate and intensive biodiversity assessments are vital. DNA‐based techniques and especially environmental (e)DNA metabarcoding is becoming a powerful monitoring tool.

The Effects of Paleoclimatic Events on Mediterranean Trout: Preliminary Evidences from Ancient DNA. [PDF]

PLoS ONE, 2016
In this pilot study for the first time, ancient DNA has been extracted from bone remains of Salmo trutta. These samples were from a stratigraphic succession located in a coastal cave of Calabria (southern Italy) inhabited by humans from upper ...

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics

Molecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of
