Genome-wide nucleotide diversity of hatchery-reared Atlantic and Mediterranean strains of brown trout Salmo trutta compared to wild Mediterranean populations.

Journal of Fish Biology, 2016
A genome-wide assessment of diversity is provided for wild Mediterranean brown trout Salmo trutta populations from headwater tributaries of the Orb River and from Atlantic and Mediterranean hatchery-reared strains that have been used for stocking. Double-

Museum samples could help to reconstruct the original distribution of Salmo trutta complex in Italy.

Journal of Fish Biology, 2017
Partial D-loop sequences of museum specimens of brown trout and marble trout (Salmo trutta species complex) collected from Mediterranean rivers in the late 19th century were analysed to help to describe the native distribution of these species.

Effects of hydropeaking on the spawning behaviour of Atlantic salmon Salmo salar and brown trout Salmo trutta.

Journal of Fish Biology, 2016
An in situ camera set-up was used to study the spawning activity of Atlantic salmon Salmo salar and brown trout Salmo trutta throughout two consecutive seasons in a spawning area affected by hydropower-related pulse flows due to hydropeaking. The purpose

Temporal stability and rates of post-depositional change in geochemical signatures of brown trout Salmo trutta scales.

Journal of Fish Biology, 2016
This study investigates temporal stability in the scale microchemistry of brown trout Salmo trutta in feeder streams of a large heterogeneous lake catchment and rates of change after migration into the lake. Laser-ablation inductively coupled plasma mass

Impact of Endocrine Disruptors on Vitellogenin Concentrations in Wild Brown Trout (Salmo trutta trutta)

Bulletin of Environmental Contamination and Toxicology, 2020
The adverse effects of endocrine disruptors (EDs) on aquatic wildlife and human health represent a current issue of high public concern. Substantial knowledge of the level of estrogenic EDs in fish has accumulated from field surveys. For this purpose, a survey of wild brown trout (Salmo trutta trutta) was carried out to assess the incidence of EDs in ...

An eDNA assay for Irish Petromyzon marinus and Salmo trutta and field validation in running water.

Journal of Fish Biology, 2015
This pilot study presents an environmental DNA (eDNA) assay for sea lamprey Petromyzon marinus and brown trout Salmo trutta, two species of economic and conservation importance in the Republic of Ireland. The results demonstrate the effectiveness of eDNA

First molecular data on Eimeria truttae from brown trout (Salmo trutta)

Parasitology Research, 2019
The genus Eimeria comprises obligate intracellular protozoan parasites belonging to the phylum Apicomplexa. Members of this genus cause enteric disease in a wide range of vertebrate hosts, including fish, reptiles, birds, and mammals. A total of 157 species of Eimeria that parasitize fish have been described; however, molecular information regarding ...

Three brown trout Salmo trutta lineages in Corsica described through allozyme variation.

Journal of Fish Biology, 2015
The brown trout Salmo trutta is represented by three lineages in Corsica: (1) an ancestral Corsican lineage, (2) a Mediterranean lineage and (3) a recently stocked domestic Atlantic S.

MYOFIBRILLOGENESIS OF THE LATERAL MUSCULATURE IN THE TROUT (SALMO TRUTTA L.)

Development, Growth and Differentiation, 1979
The developing sarcomeres in the lateral musculature of 60-somite trout embryos have been examined with special reference to the ultrastructure and sequence of events accompanying sarcomere formation. Myogenesis begins at the first somites in the head region and progresses towards the tail of the embryo.

Thermoregulatory behavior of brown trout, Salmo trutta

Hydrobiologia, 1979
Brown trout, Salmo trutta, were allowed to thermoregulate individually in an electronic shuttlebox. Pooled data for 6 fish showed a diel pattern of preferred temperature, with a diurnal minimum of 10.3°C, an early nocturnal maximum of 13.7°C, a less pronounced mid-scotophase minimum of 11.7°C, and a secondary dawn maximum of 12.8°C, in a somewhat ...
