Ocean acidification (OA) has had significant negative effects on oyster populations on the west coast of North America over the past decade. Many studies have focused on the physiological challenges experienced by young oyster larvae in high pCO₂/low pH seawater with reduced aragonite saturation state (Ωarag), which is characteristic of...
In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...
Aquaculture is a continuously growing industry, but rising problems are disease and antibiotic resistance. A common disease-causing pathogen in oyster aquaculture is Vibrio coralliilyticus (Vcor). Vcor infection of oyster larvae causes near 100% mortality within 48 hours, which is devastating to oyster hatcheries. One potential method of controlling Vcor outbreaks...
Rockfishes (Sebastes) are important species for commercial and recreational fishing, as well as evolutionary and ecological research. It can be impractical to identify the sex of rockfishes using visual identification or lethal dissection, and the sex-determination systems of these species have not been studied extensively. The aim of this research...
This dataset was produced as a result of experiments conducted with simple and alginate complex particles that were used to evaluate feeding in California yellowtail and white seabass post larvae. Retention data was collected from a series of retention trials whereby particles were suspended in seawater for various lengths of...
Dungeness crab (Cancer magister) is an important commercial species along the west coast of North America, and its population dynamics are highly influenced by interactions between environmental variability and early life history distribution. However, the distribution of the early larvae stages of Dungeness crab offshore is poorly known. To fill...
Marine protected areas (MPAs) are used in ecosystem-based management (EBM) to increase the abundance and biomass of targeted species and protect their ecosystems by restricting certain human activities. Marine reserves (i.e. no-take MPAs) aim to achieve this by prohibiting harvest in the area. While MPAs are currently evaluated through assessments...
Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...
Recognisable debris from the Great Tōhoku Earthquake and Tsunami of March 2011 began arriving on the coasts of Oregon and Washington, USA in June 2012. This debris often carried fouling Japanese marine algae, and there was concern that these species might recruit and invade northeast Pacific shores. From June 2012...
Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...
