After a long absence, beaver Castor fiber are rapidly returning to Europe. Their dam‐building and tree‐felling behaviour may have consequences for salmon Salmo salar and sea trout Salmo trutta management. In 2003 we investigated the parallel use of stream sections by beaver, sea trout and salmon and determined the potential hindrance that beaver dam‐building presented for reproducing salmon and sea trout along 65 km of the Numedalslågen River and tributaries, a major Norwegian catchment. We… 
Impact of Beaver Dams on Abundance and Distribution of Anadromous Salmonids in Two Lowland Streams in Lithuania
TLDR
Increase in abundances of salmonid parr in the stream between the beaver dams and decrease below the dams were recorded in November, at the time of spawning of Atlantic salmon and sea trout, but no significant changes were detected in the sections upstream of the dams.
Beaver Effects on Trout and Salmon-Wikipedia
  • Environmental Science
  • 2017
Beaver ponds have been shown to have a beneficial effect on trout and salmon populations. Many authors believe that the decline of salmonid fishes is related to the decline in beaver populations.
Beaver-Salmonid Working Group
Significant overlap is predicted between beaver and salmon habitat in Scotland. Given the economic and cultural value of the wild salmonid fishery, and current vulnerability of spring salmon stocks,

Reintroduction of beaver (Castor spp) may facilitate rehabilitation of freshwater habitats providing a cost-effective sustainable means of improving ecological conditions. Despite extensive research,
Beavers in Russian forest-steppe — characteristics of ponds and their impact on fishes and amphibians
The study of beaver’s (Castor fiber) impact on steppe rivers’ ecosystems was held within the Privolzhskaya Lesostep’ State Nature Reserve (Penza Province, Russia). We investigated how pond age and

Inter‐stage survival of wild juvenile Atlantic salmon, Salmo salar L.
TLDR
Density-dependent factors related to a beaver dam, which limited spawning distribution, may have contributed to poor survival and increased fry emigration in one year and environmental factors, particularly winter conditions, in streams such as Catamaran Brook may act as bottlenecks to natural production of Atlantic salmon.
Seasonal and spatial microhabitat selection and segregation in young Atlantic salmon, Salmo salar L., and brown trout, Salmo trutta L., in a Norwegian river
TLDR
Seasonal microhabitat selection by sympatric young Atlantic salmon and brown trout was studied by diving, and habitat suitability curves based on observations of fish occupancy of habitat at median or base flow may not be suitable in habitat simulation models, where available habitat is projected at substantially greater water flows.
Temporal and spatial segregation of spawning in sympatric populations of Atlantic salmon, Salmo salar L., and brown trout, Salmo trutta L.
TLDR
It is concluded that low survival of hybrids after hatching does not explain the low frequency of hybrids observed in sympatric populations of salmon and trout.
Habitat Utilization by Juvenile Pacific Salmon (Onchorynchus) in the Glacial Taku River, Southeast Alaska
Habitat utilization was determined in summer 1986 by sampling 54 sites of nine habitat types: main channels, backwaters, braids, channel edges, and sloughs in the river; and beaver ponds, terrace

TLDR
Results suggest that useful models can be derived and if a river system is mapped, and stratified by habitat, then smolt yield could be predicted and the required egg deposition could be estimated, and future research could provide useful models for assessing productive capacity of a habitat, and optimum densities.
Beaver-Trout Relationship in the Headwaters of Sunkhaze Stream, Maine
TLDR
Forage fishes appeared to be somewhat more abundant in the beaver ponds than in the open stream and constituted an unexpectedly high percentage of the food of 6- to 10-inch brook trout taken in the ponds.

In November 1998 we were shown a selection of riparian habitats in Scotland and asked to assess their suitability for beaver based on our experience in working with beaver elsewhere. Though many
Spatial niche variability for young Atlantic salmon (Salmo salar) and brown trout (S. trutta) in heterogeneous streams
TLDR
Stream habitat selection studies are reviewed and results to variable and interacting abiotic and biotic factors are related, showing flexibility with respect to preferred water velocity, depending on fish size, intra- and interspecific competition, and predation risk.

TLDR
The practicality and benefits of reintroducing or restoring beaver populations will vary according to location, and should be considered in conjunction with a managementplan to control their densities.
