Dispersal, Boundary Processes, and Trophic-Level Interactions in Streams Adjacent to Beaver Ponds
I. Schlosser performed a long-term study to analyze changes to species density, fish predation, and precipitation over time in beaver ponds and their associated streams. In addition to an experiment that looked at the effects of these temporal changes on invertebrates. Yearly, there were significant variations in the amount of precipitation. The researcher suggests that dispersal is a significant factor in determining fish density and diversity, as well as effects of their predation on invertebrates.
Impact of Beaver Dams on Abundance and Distribution of Anadromous Salmonids in Two Lowland Streams in Lithuania
European beaver dams impeded movements of anadromous salmonids as it was established by fishing survey, fish tagging and redd counts in two lowland streams in Lithuania.
The general ecology of beavers (Castor spp.) as related to their influence on stream ecosystems and riparian habitats, and the subsequent effects on fish – a review
Whether beaver-induced changes of fish populations are beneficial or harmful will depend on the prevailing constraints on local fish species composition and abundance.
Beaver Impact on Stream Fish Life Histories – The Role of Landscape and Local Attributes
Researchers examined interactions between beaver and fish communities in the types of streams selected for Eurasian beaver re-colonization. They found several critical elements of fish communities in these mountain streams that relate to beaver activity and its effects.

Final ESA Recovery Plan for Oregon Coast Coho Salmon (Oncorhynchus kisutch) 2016
This recovery plan provides guidance to improve the viability of coho salmon to the point that it meets the delisting criteria and no longer requires ESA protection.
Guidelines for Salmonid Passage at Stream Crossings
This document provides guidelines for design of stream crossings to aid upstream and downstream passage of migrating salmonids, and is intended to facilitate the design of a new
generation of stream crossings.
