Use of extractable lipofuscin as an age biomarker to determine age structure of ghost shrimp (Neotrypaea californiensis) populations in west coast estuaries

Creator:: Cassidy, Katelyn M.
Abstract:: Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements, such as carapace length, are often used to estimate age because methods for direct ageing do not exist. However, variability in individual growth rate and molt frequency can...

Integrating fleets, markets and ocean dynamics : a bioeconomic analysis of the Oregon ocean shrimp fishery

Creator:: Gallagher, Charmaine Marie
Abstract:: Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

The use of wax spray beads (WSB) for iodine enrichment of Artemia sp. for use as a live food for zebrafish (Danio rerio) larvae

Creator:: Hawkyard, Donald Matthew
Abstract:: Dietary iodine may play an important role in the nutritional health of freshwater fish larvae. Artemia, commonly used for the culture of larval zebrafish (Danio rerio), contain low concentrations of iodine when compared with wild zooplankton. Water-soluble micronutrients, such as iodine, are difficult to deliver to Artemia due to rapid...

Delivering oxytetracycline to first-feeding zebrafish Danio rerio (Hamilton) and goby Asterropteryx semipunctata (Rüppell) larvae using lipid spray beads

Creator:: Temple, Ephraim E.
Abstract:: Effective treatment of larval bacterial diseases is a difficult problem when culturing ornamental fish. Oral administration of antibiotics using existing microparticle types is not effective due to high leakage rates; furthermore, injection of larvae is not practical. Treatment is currently limited to use of antibiotic baths, . In this study,...

Is the laboratory growth of Pacific oyster spat, Crassostrea gigas, exposed to varying salinities, predictive of their growth in the estuary?

Creator:: Brooks, Christopher
Abstract:: Results of this study suggest that laboratory growth of full-sib families of five month old Pacific oyster spat can be predictive of growth to market size at different grow-out sites. Seven to ten millimeter spat were selected from each of fifteen full-sib families and commercially available polyploids. Each family was...

Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Improving Pacific oyster (Crassostrea gigas) production through selective breeding

Creator:: Evans, Sanford, 1968-
Abstract:: Shellfish growers have expressed interest in developing high-yielding oyster strains through selective breeding. This dissertation has three objectives to help determine the effects of genetic and environmental variation on production traits (body weight, survival, and yield) of Pacific oysters grown in the Pacific Northwest. Objective 1: Determine if relative family...

An Integrated Approach to the Investigation of Age, Growth and Population Dynamics of Burrowing Thalassinidean Shrimps in a U.S. West Coast Estuary

Creator:: Bosley, Katelyn Marie
Abstract:: Two indigenous species of burrowing shrimp inhabit and often dominate the intertidal zone of estuaries along the US West Coast, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species are considered ecosystem engineers and play a role in maintaining estuarine health and ecosystem function. They...

The Genetics of Larval Fitness in the Pacific Oyster: Responses to Acidified Seawater and Temporally Dynamic Selection Processes

Creator:: Durland, Evan R.
Abstract:: The Pacific Oyster (Crassostrea gigas) is one of the most economically and ecologically significant shellfish species worldwide. In the Pacific Northwest United States (PNW), the sustainability oyster stocks is increasingly threatened by ocean acidification (OA), which has had significant negative effects on the aquaculture industry in this region over the...
