Feeding habits of the alien brook trout Salvelinus fontinalis and the native brown trout Salmo trutta in Czech mountain streams

Knowledge and Management of Aquatic Ecosystems, 2017
Quantifying patterns of prey resource use is fundamental to identify mechanisms enabling the coexistence of related fish species. Trophic interactions between the native brown trout, Salmo trutta, and the introduced brook trout, Salvelinus fontinalis ...

Biogeography of Atlantic Salmon in the Cape Breton Highlands, Canada

Fisheries Management and Ecology, EarlyView.
ABSTRACT Atlantic Salmon (Salmo salar) populations have experienced significant declines in recent decades. In Canada, conservation efforts are divided into 16 designatable units (DUs) to address unique regional challenges among genetically distinct populations.

Do Habitat Restoration Efforts and the Associated Releases of Hatchery‐Reared Fish Affect the Genetic Diversity and Integrity of Native Brown Trout Populations?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Habitat restoration may protect brown trout (Salmo trutta) populations from loss of genetic diversity by increasing environmental carrying capacity and, consequently, population size. However, the accompanying release of hatchery‐reared fish may threaten the genetic integrity of native populations through introgression.

Recovery of Hafnia alvei from diseased brown trout, Salmo trutta L., and healthy noble crayfish, Astacus astacus (L.), in Bulgaria

, 2014
Hafnia alvei was isolated in Bulgaria from healthy noble crayfish, Astacus astacus (L.), and then from farmed diseased brown trout, Salmo trutta L., with signs of haemorrhagic septicaemia.

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Restoration of native Mediterranean brown trout Salmo cettii Rafinesque, 1810 (Actinopterygii: Salmonidae) populations using an electric barrier as a mitigation tool

The European Zoological Journal, 2018
This study assessed the effectiveness of a novel conservation strategy for the native brown trout populations in Sardinia (Italy). The conservation measures included: (i) installation of an electric fish barrier; (ii) removal of all the resident ...

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Loss of native brown trout diversity in streams of the continental Croatia

Frontiers in Environmental Science
Introduction: The genetic diversity of brown trout in the Western Balkans has been disrupted by the introduction of non-native Atlantic phylogenetic lineages and non-native haplotypes of the Danubian phylogenetic lineage.

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.
