Status of the European Green Crab, Carcinus maenas, (aka 5-spine crab) in Oregon Estuaries. Report for 2022

Creator:: Yamada, Sylvia Behrens, Royer, Cameron, Schooler, Shon, Flitcroft, Rebecca, Vance, Mitch, Randall, Andrea, and Fisher, Jennifer
Abstract:: The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...

Characterizing the Spread and Consequences of Mycoplasma ovipneumoniae on Bighorn Sheep (Ovis canadensis) in the Northern Basin and Range Ecosystem

Creator:: Spaan, Robert S.
Abstract:: North American bighorn sheep (Ovis canadensis) have experienced significant declines and population extirpations due to novel pathogens such as Mycoplasma ovipneumoniae. This disease continues to limit the population restoration of bighorn sheep. Therefore, understanding the demographic consequences of pathogen presence and the risk of contact between bighorn populations and potential...

The Environmental, Economic, and Social Factors that Contribute to the Importance of the Pacific Razor Clam (Siliqua patula) Fishery for Oregon Coastal Communities: A Northern Oregon Case Study

Creator:: Baker, Laura C.
Abstract:: Pacific razor clams (Siliqua patula) are narrow oblong bivalves that can be found in sandy habitats along the western coast of the United States, from Alaska (Aleutian Islands) to southern California (Pismo Beach). In Washington state, the razor clam fishery has been documented to be an important contributor to the...

Assessing Mercury Levels, Health Metrics, and Immune Function in Non-stranded Male California and Steller Sea Lions in Oregon

Creator:: Rae, Samantha N.
Abstract:: California and Steller sea lions (Zalophus californianus, Eumetopias jubatus, respectively) are considered sentinel species because they have long life spans, are long-term coastal residents, feed at high trophic levels, and have large blubber stores that serve as depots for anthropogenic toxicants. There are few studies on sea lion health and...

Offspring of first-generation hatchery steelhead trout (Oncorhynchus mykiss) grow faster in the hatchery than offspring of wild fish, but survive worse in the wild: Possible mechanisms for inadvertent domestication and fitness loss in hatchery salmon

Creator:: Blouin, Michael S., Wrey, Madeleine C., Bollmann, Stephanie R., Skaar, James C., Twibell, Ronald G., and Fuentes, Claudio
Abstract:: Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values...

Exploring biophysical linkages between coastal forestry management practices and aquatic bivalve contaminant exposure

Creator:: Scully-Engelmeyer, Kaegan, Granek, Elise F., Nielsen-Pincus, Max, Lanier, Andy, Rumrill, Steven S., Moran, Patrick, Nilsen, Elena, Hladik, Michelle L., and Pillsbury, Lori
Abstract:: Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory...

Status of the European Green Crab, Carcinus maenas, in Oregon and Washington coastal estuaries in 2019

Creator:: Yamada, Sylvia Behrens, Schooler, Shon, Heller, Renee, Donaldson, Luke, Takacs, Graham T., Randall, Andrea, Buffington, Chelsey, and Akmajian, Adrianne
Abstract:: The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. After the arrival of a strong year class in 1998, significant recruitment to the populations occurred only in 2003, 2005, 2006, 2010, 2015, 2016, 2017, 2018 and 2019. Warm winter water temperatures,...

Greater Sage-grouse conservation assessment and strategy for Oregon: A plan to maintain and enhance populations and habitat

Creator:: Hagen, Christian
Abstract:: Greater sage-grouse (Centrocercus urophasianus) were once found in most grassland and sagebrush (Artemisia spp.) habitats east of the Cascades in Oregon. European settlement and conversion of sagebrush steppe into agricultural production led to extirpation of the species in the Columbia Basin by the early part of the 1900s, but sagebrush...

The bay clams of Oregon : their economic importance, relative abundance, and general distribution

Creator:: Marriage, Lowell D. and Oregon. Fish Commission
Abstract:: An average of approximately 200,000 pounds of bay clams were harvested annually in Oregon for the years 1943-49, inclusive. The commercial harvest of bay clams is composed of the gaper, cockle, and softshell clams. The recreational, or noncommercial, harvest of bay clams is composed mainly of the gaper, cockle, softshell,...

Analysis of factors affecting the production of chum salmon (Oncorhynchus keta) in Tillamook Bay

Creator:: Henry, Kenneth A. and Oregon. Fish Commission
Abstract:: Tillamook Bay chum salmon are caught commercially by gill-nets, both set and drift, and from 1928 through 1949 the landings have averaged 819,689 pounds per season. More chum salmon are caught on Tillamook Bay than on the rest of the Oregon coastal rivers combined. These fish enter the ocean only...
