Effect of dietary vitamin E and selenium on growth, survival and the prevalence of Renibacterium salmoninarum infection in chinook salmon (Oncorhynchus tshawytscha) Effect of dietary vitamin E and selenium on growth, survival and the prevalence of Renibacterium salmoninarum infection in chinook salmon (Oncorhynchus tshawytscha)
Groups of juvenile spring chinook salmon naturally infected with Renibacterium salmoninarum, the causative agent of bacterial kidney disease, were fed diets containing different levels of vitamin E and selenium for 214 days in fresh water and 110 days in seawater. The fish were fed vitamin E at concentrations of either 53±3 mg (designated e) or 299±9 mg (designated E) α-tocopheryl...

Vulnerability to predation and physiological stress responses of experimentally descaled juvenile Chinook salmon, Oncorhynchus tshawytscha Vulnerability to predation and physiological stress responses of experimentally descaled juvenile Chinook salmon, Oncorhynchus tshawytscha
Juvenile salmonids,Oncorhynchus spp., commonly encounter conditions (e.g., during hatchery release and dam passage) that result in damage to the skin, scale, and slime complex. We conducted laboratory experiments to determine if descaling of juvenile chinook salmon,O. tshawytscha, increased their vulnerability to predation, and to assess the physiological stress responses elicited by...

Characterization of the glycoprotein of infectious hematopoietic necrosis virus using neutralizing monoclonal antibodies Characterization of the glycoprotein of infectious hematopoietic necrosis virus using neutralizing monoclonal antibodies
To study the antigenic nature of the glycoprotein (G protein) of infectious hematopoietic necrosis virus (IHNV), 31 neutralizing monoclonal antibodies (MAbs) were produced against a reference isolate of the virus. The MAbs were compared using a neutralization assay, an enzyme-linked immunosorbent assay (ELISA), and by immunoblotting of the G protein in the native, reduced, and...

Importance of spatial pattern in estimating predation on juvenile salmonids in the Columbia River Importance of spatial pattern in estimating predation on juvenile salmonids in the Columbia River
The impact of piscivores in aquatic systems is often estimated by assuming that predation rate and predator density can be characterized as means throughout large, homogeneous areas. Predation losses of juvenile Pacific salmonids Oncorhynchus spp. migrating through Columbia River reservoirs were previously estimated with the assumption that each reservoir consisted of one or two...

Northern squawfish Ptychochelius oregonensis, O2 consumption rate: Effects of temperature and body size Northern squawfish Ptychochelius oregonensis, O2 consumption rate: Effects of temperature and body size
Northern squawfish, Ptychocheilus oregonensis (live weight range 0.361–1.973 kg), O2consumption was measured with temperature-controlled, flow-through respirometers for >24 h. Mean standard O2 consumption rate of northern squawfish increased with acclimation temperature: 24.3, 49.1, 75.0, and 89.4 mg∙kg−0.67∙h−1 at 9, 15, 18, and 21 °C, respectively. Q10analysis showed that O2...
