Gen Comp Endocrinol 148:195-202. 2006..Confinement stress did not impair feed intake subsequently in SW, but our results suggest that feed intake was suppressed by the change of the media from FW to SW...
- Stress and fish reproduction: the roles of allostasis and hormesisCarl B Schreck
Oregon Cooperative Fish and Wildlife Research Unit, U S Geological Survey, Oregon State University, Corvallis, OR 97331, USA
Gen Comp Endocrinol 165:549-56. 2010..The concept of hormesis is a useful way to think about the effect of stressors on fish reproduction since responses can be nonmonotonal, often biphasic...

J Vet Diagn Invest 25:341-51. 2013..salmonicida. Kappa analysis for agreement between Blue Book and histology methods was poor to moderate. However, histological observations revealed the presence of other pathogens that would not be detected by other methods...
- Effect of commercially available egg cures on the survival of juvenile salmonidsShaun Clements
Oregon Department of Fish and Wildlife, Corvallis, Oregon, United States of America
PLoS ONE 6:e21406. 2011..We conclude that consumption of eggs cured with sodium sulfite has the potential to cause mortality in juvenile steelhead and Chinook salmon in the wild...
