Accurate determination of escapement is necessary for analysis of the status of important fish stock. In an effort to evaluate and develop more accurate Pacific salmon escapement estimation technique, a time-lapse video recording system and a computerized counting system were tested. The...

What Goes Up Does Not Come Down: the Stock Composition and Demographic Characteristics of Upstream Migrating Steelhead Differ from Post-spawn Emigrating Kelts
Iteroparity (repeat spawning) is a life history attribute with significant conservation value for at-risk populations of steelhead trout (Oncorhynchus mykiss). However, stock-specific rates of iteroparity and abundance of post-spawned steelhead “kelts” can be difficult to monitor in...

Whole Genome Resequencing Reveals Genomic Regions Associated with Thermal Adaptation in Redband Trout
Adaptation to local environments involves evolution of ecologically important traits and underlying physiological processes. Here, we used low coverage whole‐genome resequencing (lcWGR) on individuals to identify genome regions involved in thermal adaptation in wild redband trout Oncorhynchus...

Wy-Kan-Ush-Mi Wa-Kish-Wit: How Indigenous Knowledge Has Shaped Modern Fisheries Management in the Columbia River
The Columbia River Inter-Tribal Fish Commission (CRITFC) was formed in 1977 to provide a unified voice in Columbia River fisheries management for the Nez Perce, Yakama, Umatilla, and Warm Springs tribes. Following extremely low returns of salmon in the early 1990s and regional inaction to reverse...

Year-to-year Variability in Ocean Recovery Rate of Columbia River Upriver Bright Fall Chinook Salmon (Oncorhynchus tshawytscha)
Unusually large returns of several stocks of fall Chinook salmon (Oncorhynchus tshawytscha) from the U.S. Northwest commonly occurred during the late 1980s. These synchronous events seem to have been due to ocean rather than freshwater conditions because natal rivers of these stocks were...

Young-of-the-year Fish Assemblages as an Alternative to Adult Fish Monitoring for Ecological Quality Evaluation of Running Waters
The EU’s Water Framework Directive (WFD) in particular makes good use of riverine biota—including fish—as ecological indicators of river integrity. However, it is also important to examine when our indicators fail to serve the purpose for which they were originally intended: to consistently...
