Non-lethal Detection of Skin Injuries in Juvenile Chinook Salmon Oncorhynchus tshawytscha by Fast Green FCF Dye

In fish, as in humans, an intact epidermis is critical to defense against entry of pathogens into the skin. Macroscopic examination of scale loss is the principal method of evaluating physical damage to juvenile salmonids out-migrating through hydroelectric dams in the Snake and Columbia Rivers, and in fish subjected to capture and handling procedures in locations such as hatcheries, fish...

Contaminants in Puget Sound Forage Fishes and Impacts to the Marine Food Web

Toxic chemical pollutants have been released into Puget Sound for decades by human activities. There’s a wide range of contaminants, from persistent compounds like polychlorinated biphenyls (PCBs) and flame retardants to contaminants of emerging concern. Aquatic species can be exposed to and accumulate contaminants, causing disease or disruption of biological processes like growth or...

Investigation and Disease Prevention of Spring Viremia of Carp Virus (SVCV)

There has been long history of disease outbreaks and economic losses in wild and farmed carp species due to SVCV. Formerly thought to be restricted to Europe and Asia, SVCV was detected for the first time in North America from diseased koi at a North Carolina fish farm in 2002, and there were extensive eradication efforts with 135,000 fish euthanized in addition to the ~15,000 that died from...

Antimony In and Around the Yellow Pine Deposit, Central Idaho

Project objectives are to document the origin of the Yellow Pine gold-antimony deposit and, by extension, the origin of this deposit type. Our goal is to understand the structural, tectonic, and magmatic setting of the deposit, the character of the ore-transporting fluids, the conditions of ore deposition, and the regional stratigraphic framework and geochemical ore controls of metasedimentary...

Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest

Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century.  Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred.  In the past two decades...

Data to Support Efficacy Studies of Injectable Tulathromycin for Reduction of Vertical Transmission of Renibacterium salmoninarum in Spring Chinook Salmon (Oncorhynchus tshawytscha)

Bacterial kidney disease (BKD) caused by Renibacterium salmoninarum (Rs) occurs nearly worldwide where wild or cultured salmonid fishes are present. Control of BKD is confounded by its two modes of transmission, horizontal (fish-to-fish) and vertical (from female parent to progeny via the eggs). A highly successful BKD control strategy employed in Pacific Northwest hatcheries cu

Susceptibility of Nanophyetus salmonicola cercariae to formalin, hydrogen peroxide and seawater

The ability of formalin, PEROX-AID® (hydrogen peroxide), and seawater to kill waterborne Nanophyetus salmincola cercariae was evaluated in vitro. Newly emerged waterborne cercariae survived for extended periods in freshwater, with 50-74% survival occurring in negative control groups after 24 hr. Exposure to dilutions of formalin reduced this survival time, with 0% of cerca

February 22, 2017

Atmospheric rivers are a global weather phenomenon that can bring large amounts of rain or snow to the U.S. West Coast each year. These rivers of wet air form over the Pacific Ocean near Hawaiʻi and pick up large amounts of moisture from the tropics and on their way to the West Coast. This moisture is carried in narrow bands across the Pacific Ocean to California, Oregon, Washington and Nevada.
