The Potential Role of Haploblocks in the Persistence of Small, Isolated Populations of Brook Trout (Salvelinus fontinalis) [PDF]

Ecology and Evolution
Understanding the role of structural variants such as chromosomal inversions in local adaptation among small, isolated populations is an important addition to robust conservation strategies, as most studies investigating inversions to date have been ...

Hydrogeochemical controls on brook trout spawning habitats in a coastal stream [PDF]

Hydrology and Earth System Sciences, 2018
Brook trout (Salvelinus fontinalis) spawn in fall and overwintering egg development can benefit from stable, relatively warm temperatures in groundwater-seepage zones.

Range-wide climate risk and adaptive potential in a cold-water fish species [PDF]

Nature Communications
Predicting extinction risk from climate change requires understanding adaptive variation and local adaptation across species’ ranges. We combine experimental and -omics approaches with climate change modeling to identify molecular mechanisms of local ...

Water quality indicators in high-density cage farming of trout [PDF]

BIO Web of Conferences, 2023
Trout fishing means raising fish in water whose temperature does not exceed +18°C under completely or partially artificial conditions. Today, several fish belonging to the salmon family are bred in cold water fisheries in the world. These are river trout

The Lifetime Migratory History of Anadromous Brook Trout (Salvelinus fontinalis): Insights and Risks from Pesticide-Induced Fish Kills

Fishes, 2022
Brook trout populations in Prince Edward Island, Canada, have experienced over 50 pesticide-related fish kills since the 1960s. Life history evaluation of large sea-run brook trout recovered following two fish kill events was compared with a reference ...

Assessing Hybridization Risk Between ESA-Listed Native Bull Trout (Salvelinus confluentus) and Introduced Brook Trout (S. fontinalis) Using Habitat Modeling

Frontiers in Environmental Science, 2022
The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data on hybrid occurrences makes hybridization risk assessment difficult.

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Distribution of non-native brook trout (Salvelinus fontinalis) across Norwegian waterbodies – is it an invasive species?

Fauna Norvegica, 2018
Non-native brook trout (Salvelinus fontinalis MITCHILL, 1815) was introduced into Norway in 1883. However, it was not until the late 1970s that this acid-tolerant salmonid species was stocked into many acidified lakes that many populations became ...

Interspecific association of brown trout (Salmo trutta) with non-native brook trout (Salvelinus fontinalis) at the fry stage [PDF]

, 2017
The introduction of non-native brook trout (Salvelinus fontinalis) in Europe has led to displacement and decreasing populations of native brown trout (Salmo trutta).
