Dissolved saxitoxin causes transient inhibition of sensorimotor function in larval Pacific herring (Clupea harengus pallasi) Kathi A. Lefebvre , N Dissolved saxitoxin causes transient inhibition of sensorimotor function in larval Pacific herring (Clupea harengus pallasi) Kathi A. Lefebvre , N
Herring (Clupea harengus pallasi) spawning sites in Puget Sound, Washington overlap spatially and temporally with blooms of Alexandrium catenella, a toxic dinoflagellate species responsible for paralytic shellfish poisoning. Consequently, newly hatched herring larvae may be regularly exposed to the suite of dissolved paralytic shellfish toxins that are released into the water column from...

Combined use of the ASK and SHK-1 cell lines to enhance the detection of infectious salmon anemia virus Combined use of the ASK and SHK-1 cell lines to enhance the detection of infectious salmon anemia virus
Infectious salmon anemia (ISA) is a severe disease primarily affecting commercially farmed Atlantic salmon (Salmo salar) in seawater. The disease has been reported in portions of Canada, the United Kingdom, the Faroe Islands, and the United States. Infectious salmon anemia virus (ISAV), the causative agent of ISA, has also been isolated from several asymptomatic marine and salmonid fish...

Diel spawning behavior of chum salmon in the Columbia River Diel spawning behavior of chum salmon in the Columbia River
We conducted a study during 2003 in a side channel of the Columbia River downstream of Bonneville Dam to describe the diel spawning behavior of wild chum salmon Oncorhynchus keta. We collected observational data on 14 pairs of chum salmon using a dual-frequency identification sonar. Spawners of both genders were observed chasing intruders during nighttime and daytime as nests were...

The Columbia River Research Laboratory The Columbia River Research Laboratory
The U.S. Geological Survey's Columbia River Research Laboratory (CRRL) was established in 1978 at Cook, Washington, in the Columbia River Gorge east of Portland, Oregon. The CRRL, as part of the Western Fisheries Research Center, conducts research on fishery issues in the Columbia River Basin. Our mission is to: 'Serve the public by providing scientific information to support the...

A spatial model of potential jaguar habitat in Arizona A spatial model of potential jaguar habitat in Arizona
The jaguar (Panthera onca) is an endangered species that occasionally visits the southwestern United States from Mexico. The number of jaguar sightings per decade has declined over the last 100 years in Arizona, USA, raising conservation concerns for the species at a local and national level. In 1997, state, federal, and local governments with land-management responsibilities agreed to

Passage behavior of radio-tagged yearling Chinook salmon and steelhead at Bonneville Dam, 2004: Revised for corrected spill annual report Passage behavior of radio-tagged yearling Chinook salmon and steelhead at Bonneville Dam, 2004: Revised for corrected spill annual report
Flow augmentation, spill, surface collection, and improved turbine guidance systems have been identified as potential management actions to improve passage efficiency and survival of outmigrating juvenile salmonids. The U.S. Army Corps of Engineers (USACE), along with regional, state, and federal resource agencies, has designed and implemented studies to determine which management...

Fish can get diseases too Fish can get diseases too
Infectious diseases are increasingly recognized as an important component of the ecology of fish in the wild. Many of the viral, bacterial, protozoan and fungal pathogens of fish that were initially discovered in captive fish have their origin among wild populations; however, the impact of disease among these free-ranging stocks has been difficult to study. At the WFRC, combinations of...
