A Cautionary Tale for in situ Fluorometric Measurement of Stream Chlorophyll a: Influences of Light and Periphyton Biomass

The use of in situ fluorometry to estimate stream benthic chlorophyll a (Chl a) has the potential to substantially reduce sampling costs and increase the feasibility of spatial and temporal replication. We evaluated the utility of a bbe moldaenke BenthoTorch fluorometer by...

A Centralized Model for Creating Shared, Standardized, Microsatellite Data that Simplifies Inter-laboratory Collaboration

We demonstrate an efficient model for standardizing microsatellite DNA data among laboratories studying Oncorhynchus mykiss. Eight laboratories standardized 13 microsatellite loci following allele nomenclature of a central laboratory (average inter-laboratory genotyping concordance [98%])....

A Coarse Screening Process for Evaluation of the Effects of Land Management Activities on Salmon Spawning and Rearing Habitat in ESA Consultations

Spring, summer, and fall chinook salmon in the Snake River Basin have been listed as 'endangered' under the Endangered Species Act (ESA) by the National Marine Fisheries Service (NMFS). The ESA requires that activities authorized, funded, or carried out by federal agencies do not adversely modify...

A Comparison and Evaluation of Existing Land Management Plans Affecting Spawning and Rearing Habitat of Snake River Basin Salmon Species Listed Under the Endangered Species Act

This report summarizes and evaluates the major provisions of seven land management approaches for their likely effectiveness in protecting and restoring vital attributes of habitat for Snake River Basin salmon species listed as 'endangered' under the Endangered Species Act (ESA) by the National...

A Computer Program for Calculating the Distance Between Sites in the Columbia River Basin

In landscape genetics analyses, it is useful to measure the physical distance between collections or populations of interest in order to study the effect of distance on genetic diversity and population structure. Simple measurements such as Euclidean distance can be misleading, however, because fish...

A Computerized Editing System for Video Monitoring of Fish Passage

We designed and tested a videotape editing system that selected and removed video frames not containing fish images from source videotapes previously recorded in 24, 48, or 72 h time‐lapse modes. The system, based on image‐processing software and a personal computer, compressed videotapes of the...

A Distinctive Microsatellite Locus That Differentiates Ocean-type from Stream-type Chinook Salmon in the Interior Columbia River Basin

Chinook salmon Oncorhynchus tshawytscha display two life history strategies that are referred to as ocean type and stream type. Ocean-type Chinook salmon typically differ from stream-type fish in juvenile migration timing, adult spawning location, and run timing. Spatial and temporal...

A Field Study to Investigate Repeat Homing in Pacific Lampreys

In-season homing of Pacific lampreys Lampetra tridentata was investigated using radiotelemetry in the lower Columbia River from 1998 through 1999. A total of 50 Pacific lampreys were captured: 25 at Willamette Falls (river kilometer [rkm] 45 on the Willamette River, a tributary to the Columbia...

A Fish Consumption Survey of the Umatilla, Nez Perce, Yakama, and Warm Springs Tribes of the Columbia River Basin

During the fall and winter of 1991-1992, a survey was conducted among Columbia River Basin Indian tribes to determine the level and nature of fish consumption among individual tribal members. The survey was initiated to test the hypotheses that Indians in that region consume more fish than...

A Genetic Analysis of the Summer Steelhead Stock Composition in the Columbia River and Snake River Tribal and Sport Fisheries from July 1, 2012 to March 31, 2013

We used PBT and GSI to categorize the stock composition of steelhead harvested in tribal and non-tribal fisheries in the Columbia and Snake rivers. This is the second year that we have used genetic technology to parse harvest into stocks. All steelhead used for broodstock in the Snake River basin...
