Final Environmental Assessment: Snake River Basin Fall Chinook and Coho Salmon, and Resident Trout Fisheries

The Snake River is a tributary to the Columbia River. The proposed management plans include fall Chinook salmon fisheries, coho salmon fisheries, and Oregon’s resident trout fishery in the Snake River Basin.

Evolution Of Phenology In A Salmonid Population: A Potential Adaptive Response To Climate Change

Accumulating evidence has indicated that many fish populations are responding to climate change through shifts in migration time, but genetic data identifying the role of evolution in these shifts are rare. One of the first demonstrations of evolution of migration time was produced by monitoring allozyme alleles that were experimentally manipulated to genetically mark late-migrating pink salmon (Oncorhynchus gorbuscha). Here, we extend that research by using observations of the marker alleles in fry to demonstrate that these changes in migration time were caused by directional selection against the late-migrating phenotype during the oceanic phase of the salmonid life cycle. The selective event, which appeared to be driven by early vernal warming of the nearshore marine environment and consequent decreased survival of late-migrating fry relative to earlymigrating fry, decreased the late-migrating phenotype from more than 50% to approximately 10% of the total fry abundance in only one generation. These demographic changes have persisted over the subsequent 13 generations and suggest that a larger trend toward earlier migration time in this population may reflect adaptation to warming sea-surface temperatures.

2016 5-Year Review: Summary & Evaluation of Snake River Sockeye Snake River Spring-Summer Chinook Snake River Fall-Run Chinook Snake River Basin Steelhead

Many West Coast salmon and steelhead (Oncorhynchus spp.) stocks have declined substantially from their historical numbers and now are at a fraction of their historical abundance. Several factors contribute to these declines, including: overfishing, loss and degradation of freshwater and estuarine habitat, hydropower development, poor ocean conditions, and hatchery practices.

Recovery Plan for Snake River Sockeye Salmon (Oncorhynchus nerka)

The goal of ESA recovery under this plan is to improve the viability of Snake River sockeye salmon, and the ecosystems upon which they depend, to the point that they no longer require ESA protection.
