The Gill Pathogen Dermocystidium salmonis in Oregon Salmonids

Creator:: Olson, Robert E. and Holt, Richard A.
Abstract:: Intense infections of the gill pathogen Dermocystidium salmonis were associated with mortality of prespawning chinook salmon Oncorhynchus tshawytscha in several Oregon rivers in 1988. The occurrence of the pathogen in returning adult chinook salmon was monitored in several coastal Oregon stocks from 1989 to 1993. Although the prevalence of the...

Parasites as indicators of English sole (Parophrys vetulus) nursery grounds

Creator:: Olson, Robert E. and Pratt, Ivan
Abstract:: Juvenile English sole, Parophrys vetulus utilize Yaquina Bay, Oregon, as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of the-year first appeared in Yaquina Bay in February,...

Columbia River plume fronts. II. Distribution, abundance, and feeding ecology of juvenile salmon

Creator:: De Robertis, Alex, Morgan, Cheryl A., Schabetsberger, Robert A., Zabel, Richard W., Brodeur, Richard D., Emmett, Robert L., Knight, Carolyn M., Krutzikowsky, Gregory K., and Casillas, Edmundo
Abstract:: Well-defined fronts develop at the seaward edge of riverine plumes where suspended materials and planktonic organisms are concentrated by convergent water flows. Riverine plume fronts have been hypothesized to be favorable fish habitats because they can lead to localized prey aggregations. We examined the spatial distribution of juvenile Pacific salmonids...

Nocturnal feeding of Pacific hake and jack mackerel off the mouth of the Columbia River, 1998-2004: implications for juvenile salmon predation

Creator:: Emmett, Robert L. and Krutzikowsky, Gregory K.
Abstract:: Predation by piscivorous marine fishes has been hypothesized to be a primary source of marine mortality for Pacific Northwest juvenile salmon. During the springs and summers of 1998–2004, we collected predator and prey fishes (forage and juvenile salmonids) at the surface at night off the mouth of the Columbia River....

Biologically Active Factors against the Monogenetic Trematode Gyrodactylus stellatus in the Serum and Mucus of Infected Juvenile English Soles

Creator:: Moore, Michelle M., Kaattari, Stephen L., and Olson, Robert E.
Abstract:: Length of survival of the monogenetic trematode Gyrodactylus stellatus in serum and mucus collected from English soles Pleuronectes vetulus at different stages of a laboratory epizootic suggests that both the mucus and serum may be involved in resistance to the parasite. In general, trematode survival was shorter in the serum...

Abstract:: The state of the California Current system (CCS) since spring 2010 has evolved in response to the development of cooler La Nina following the dissipation of the relatively weak and short-lived El Nino event of 2009-2010. The 2009-2010 El Nino appears to have dissipated quite rapidly in early spring 2010,...

Cold front induced changes on the Florida panhandle shelf during October 2008

Creator:: Kamykowski, D., Morrison, J. M., McCulloch, A. A., Nyadjro, E. S., Thomas, C. A., Sinclair, G. A., and Grabowski Pridgen, K.
Abstract:: A significant step transition between seasonally stratified and destratified hydrographic conditions occurred during an October 2008 cruise to the Florida Panhandle Shelf along a cross-shelf transect that was sampled before and after a cold front passed through the area. Meteorological measurements from nearby ocean and land-based stations characterized the event....
