Managing water in the West: developing new tools for a critical resource Managing water in the West: developing new tools for a critical resource
Rapid population growth in the Western United States over the last century has placed increasing strains on our water supplies and aquatic ecosystems. Historically, water rights have been used to determine the allocation of water in the West, but rules and regulations related to endangered species now often drive how water is released from reservoirs in large rivers such as the lower...

Biological science in Oregon Biological science in Oregon
Fishing is an important part of Oregon's culture. The Western Fisheries Research Center (WFRC) has been conducting research in Oregon for many years to provide information that can be used by managers to help keep fish and other parts of the ecosystem healthy. Below are examples of some of WFRC's studies.

Aquatic invasive species Aquatic invasive species
Invasive species are plants or animals that are present in an ecosystem beyond their native range. They may have few natural controls in their new environment and proliferate. They can threaten native species and interfere with human activities. The Western Fisheries Research Center (WFRC) has been conducting research to understand how non-native species invade and affect ecosystems...

Measuring nighttime spawning behavior of chum salmon using a dual-frequency identification sonar (DIDSON) Measuring nighttime spawning behavior of chum salmon using a dual-frequency identification sonar (DIDSON)
The striking body coloration and morphology that Pacific salmon display during spawning coupled with elaborate courtship behaviors suggest that visual cues are important during their reproductive period. To date, virtually all existing information on chum salmon (Oncorhynchus keta) spawning behavior has been derived from studies conducted during the daytime, and has contributed to the...

Work package 4 report: Broodfish testing for bacterial infections Work package 4 report: Broodfish testing for bacterial infections
This report summarises current scientific information and experience obtained with various methods for testing of salmonid broodfish or spawn for bacterial kidney disease (BKD - Renibacterium salmoninarum infection) in order to prevent vertical transmission of the organism to the offspring. Assessment is also being performed for Flavobacterium psychrophilum infections causing rainbow...

Contaminants as viral cofactors: assessing indirect population effects Contaminants as viral cofactors: assessing indirect population effects
Current toxicological methods often miss contaminant effects, particularly when immune suppression is involved. The failure to recognize and evaluate indirect and sublethal effects severely limits the applicability of those methods at the population level. In this study, the Vitality model is used to evaluate the population level effects of a contaminant exerting only indirect, sublethal...

Blue tilapia (Oreochromis aureus) predation on fishes in the Muddy River system, Clark County, Nevada Blue tilapia (Oreochromis aureus) predation on fishes in the Muddy River system, Clark County, Nevada
Blue tilapia (Oreochromis aureus), native to North Africa and the Middle East (Courtenay and Robins 1973, Fuller et al. 1999), has been introduced around the world as a human food source, for vegetation control, and as a game fish (Costa-Pierce and Riedel 2000). Blue tilapia has been particularly successful in establishing and spreading in North American waters where it has been reported...
