In a restored, third‐order stream in northern Nova Scotia, Canada, we used redd counts over 12 years to examine the influence of beaver dams and the timing and intensity of autumn rains on spawning activity of Atlantic salmon. Most beaver dams in most years had no detectable effect on the distribution of spawning redds, but in 2004 the density of redds downstream from a three‐dam complex was significantly greater than that above, suggesting the dams were a barrier to many fish. A second complex…

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.
Field experiments to assess passage of juvenile salmonids across beaver dams during low flow conditions in a tributary to the Klamath River, California, USA
TLDR
By measuring hydraulic conditions at the major flowpaths over and around the dams, this study provides insight into conditions under which juvenile salmonids are able to cross these constructed beaver dams, which should help guide future restoration efforts.
Linking beaver dam affected flow dynamics to upstream passage of Arctic grayling
TLDR
It is demonstrated that upstream passage of fish over beaver dams is strongly correlated with hydrologic conditions with moderate controls by dam‐ and fish‐level characteristics, which provides a framework that can be applied to reduce barrier effects when and where beavers pose a significant threat to the upstream migration of fish populations.
Do Beaver Dams Impede the Movement of Trout
TLDR
Investigation of beaver dam passage by three trout species in two northern Utah streams found Native Bonneville Cutthroat Trout Oncorhynchus clarkii utah passed dams more frequently than nonnative Brown Trout Salmo trutta and nonnative Brook Trout Salvelinus fontina...
The impact of abiotic factors on daily spawning migration of Atlantic salmon (Salmo salar) in two north Swedish rivers
Atlantic salmon (Salmo salar) depends on two major migrations to fulfil their life cycle, from their birth place in rivers to sea, and back upstream the river again to spawn. Salmon stocks have been…
Impacts of Highway Construction on Redd Counts of Stream‐Dwelling Brook Trout
Abstract Sedimentation during road construction is a human impact that threatens aquatic ecosystems. Despite a large body of literature on the effect of fine sediments on the initial developmental…
Restoration of a Nova Scotia stream to enhance Atlantic salmon provides few benefits to benthic invertebrates
TLDR
This work examined the effect of successful restoration to improve habitat for spawning Atlantic salmon on benthic invertebrate communities at sites where clogging of the bottom cobble with fine silt had been alleviated, and found no substantial changes in total invertebrates, taxa richness, Simpson's diversity index or other community metrics over five years.
The response of a brown trout (Salmo trutta) population to reintroduced Eurasian beaver (Castor fiber) habitat modification
Globally, freshwaters are the most degraded and threatened of all ecosystems. In northern temperate regions, beaver (Castor spp.) reintroductions are increasingly used as a low-cost and…
Qualitative and quantitative effects of reintroduced beavers on stream fish
Reintroduction of beaver (Castor spp) may facilitate rehabilitation of freshwater habitats providing a cost-effective sustainable means of improving ecological conditions. Despite extensive research,…

Large Woody Debris Structures and Their Influence on Atlantic Salmon Spawning in a Stream in Nova Scotia, Canada
TLDR
Artificial structures mimicking naturally fallen trees in a third-order stream in northern Nova Scotia from 1992 to 2004 were installed to determine whether the structures enhanced spawning success of Atlantic salmon Salmo salar.
Effects of artificial woody structures on Atlantic salmon habitat and populations in a Nova Scotia stream
A 1‐km reach of Brierly Brook, Nova Scotia, was studied from 1995 to 2004 to determine if the addition of artificial structures mimicking large woody debris could enhance Atlantic salmon populations.…

Factors affecting the within-river spawning migration of Atlantic salmon, with emphasis on human impacts

TLDR
In a small stream in eastern Canada, the effects of an ephemeral beaver pond on the growth and maturity of age-2 Atlantic salmon Salmo salar parr tagged with passive integrated transponder tags are studied.

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.
Discharge and hydraulic interactions in contrasting channel morphologies and their influence on site utilization by spawning Atlantic salmon (Salmo salar)
TLDR
Six study sites were selected to represent the range of channel morphologies, extending from dynamic pool–riffle to transitional step–pool/plane bed reach types, used by spawning Atlantic salmon in a small upland Scottish stream, and predicted that spawning conditions should occur at discharges higher than those utilized by fish.
