Diet manipulations and color changes in Pisaster ochraceus

Creator:

Taylor, Katlyn R.

Abstract:

It has been observed and documented that Pisaster ochraceus has very striking colors, but the reasons behind the coloration are still unknown. Three coloration categories were determined and used for a feeding trial study to investigate the effects of diet on coloration in Pisaster ochraceus. This study involved 30 hand...

Visual discrimination and memory of Enteroctopus dofleini, the Giant Pacific Octopus

Creator:

Boyle, Virinda R.

Abstract:

This study evaluated the memory and visual discrimination capabilities of Enteroctopus dofleini, the Giant Pacific Octopus. Octopuses have been known to have advance sensory capabilities and through this study we challenged our specimen to remember and actively choose a specific patterned jar based on a visual pattern and positive reinforcement....

Coralline and fleshy algae volume density on epifaunal communities

Creator:

Field, Samuel J. and Gani, Christopher D.

Abstract:

Carbon dioxide emissions greatly affect the carbon chemistry mechanisms within the ocean. Carbon absorbed by the ocean, drops the pH level and creates an environment that is acidic. Acidic conditions prevent calcification mechanisms in coralline algae, and hinder their ability to establish within the intertidal. Coralline algae display structural relevance...

Comparing Metacarcinus magister settlement preferences among the seagrasses Z. marina and Z. japonica

Creator:

Jaco, Erin M. and Heidmann, Sarah

Abstract:

Metacarcinus magister, the Dungeness crab, is a commercially important species on the Pacific Northwest coast as the most profitable fishery in Oregon and an important ecological player as both predator and prey. Understanding the spatial distribution of Dungeness throughout different life history stages is beneficial both ecologically and economically. Zostera...

Development of Sex Markers for Rockfishes, Sebastes, inhabiting the Northeast Pacific Ocean

Creator:

Aycock, Hannah

Abstract:

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...

Recent pre-recruit Pacific hake (Merluccius productus) occurrences in the Northern California Current suggest a northward expansion of their spawning area

Creator:

Phillips, A. Jason, Ralston, Stephen, Brodeur, Richard D., Auth, Toby D., Emmett, Robert L., Johnson, Carrie, and Wespestad, Vidar G.

Abstract:

Coastal Pacific hake (Merluccius productus) are known to spawn in the southern California Bight from January to March, migrate north during late spring and summer to feed off Oregon, Washington, and British Columbia, and then move back to southern California in the fall. Juvenile Pacific hake nursery areas have been...

Distributions of Dungeness crab (Cancer magister) zoea in the California Current: Closing a life history gap

Creator:

Chin, Andrew

Abstract:

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...

The relationships between predatory fish, forage fishes, and juvenile salmonid marine survival off the Columbia River: a simple trophic model analysis

Creator:

Emmett, Robert L. and Sampson, David B.

Abstract:

A trophic model that simulates interactions between a predatory fish (Pacific hake, Merluccius productus), forage fish, and juvenile salmon off the Columbia River was constructed to identify if trophic interactions could account for marine mortality of Columbia River juvenile salmon. The model estimates the number of juvenile salmon that are...

Impact of Prophylactic Bacteriophage Addition on Survival of Crassostrea gigas Larvae

Creator:

Schmidt, Sarah

Abstract:

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...
