Food consumption and growth of the larvae of the Pacific oyster (Crassostrea gigas)

Creator:: Malouf, Robert E.
Abstract:: The food consumption and growth of Pacific oyster larvae were studied in three experiments making use of a constant flow apparatus. The apparatus maintained a continuous flow of various densities of algae through test chambers containing different numbers of larvae in a factorial design. Three additional experiments were conducted in...

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: 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...

Refrigerated seawater depuration for reducing Vibrio parahaemolyticus contamination in raw Pacific oysters (Crassostrea gigas)

Creator:: Yang, Qianru
Abstract:: Vibrio parahaemolyticus is a seafood-borne pathogen that can cause gastroenteritis in humans. This study investigated the effectiveness of refrigerated seawater (5°C) depuration on reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas). Raw Pacific oysters were inoculated with a mixed culture of five clinical strains of V. parahaemolyticus and depurated...

Factors Affecting the Efficacy of Depuration for Decreasing Vibrio parahaemolyticus Contamination in Pacific Oysters (Crassostrea gigas)

Creator:: Hou, Yishu
Abstract:: Vibrio parahaemolyticus is a foodborne pathogen recognized as the leading cause of acute gastroenteritis associated with consumption of raw and undercooked seafood, particularly raw oysters, with major symptoms of nausea, vomiting, abdominal cramps and diarrhea. It is estimated that 45,000 cases of V. parahaemolyticus infection occur each year in the...

Commercial application of high pressure processing for inactivating Vibrio parahaemolyticus in Pacific oysters (Crassostrea gigas)

Creator:: Ma, Lei
Abstract:: Vibrio parahaemolyticus is a Gram-negative, halophilic pathogen that occurs naturally in coastal and estuarine environments. This human pathogen is frequently isolated from a variety of seafood, particular oysters, and is the leading cause of gastroenteritis associated with seafood consumption. Several outbreaks of V. parahaemolyticus infections linked to consumption of raw...

Application of probiotics and green tea extract in post-harvest processes of Pacific oysters (Crassostrea gigas) for reducing Vibrio parahaemolyticus and extending shelf life

Creator:: Xi, Dunyu
Abstract:: Vibrio parahaemolyticus is a human pathogen which is prevalent in marine environment. Consumption of raw or undercooked seafood contaminated with V. parahaemolyticus can cause foodborne illness. This study investigated the application of probiotics in depuration for reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas) and the utilization of green...

Application of Antimicrobial Substance in Depuration for Decreasing Vibrio Parahaemolyticus Contamination in the Pacific Oysters (Crassostrea gigas)

Creator:: Shen, Xiaoye
Abstract:: Vibrio parahaemolyticus is the leading cause of foodborne illnesses associated with seafood consumption. Consuming raw or undercooked seafood contaminated with V. parahaemolyticus can result in development of acute gastroenteritis with symptoms of nausea, vomiting, abdominal cramping and watery diarrhea within 24 hours of infection. Illness is usually self-limited and lasts...

Insights from stable isotope dynamics into the sensitivity of larval Pacific oysters to ocean acidification

Creator:: Brunner, Elizabeth Lev
Abstract:: Larvae of the Pacific Oyster, Crassostrea gigas, at Whiskey Creek Shellfish Hatchery (WCH) in Netarts Bay, Oregon, are negatively impacted by high-CO₂ water and exposure during the initial shell formation period appears to be particularly damaging. To investigate the mechanism of this early susceptibility, several cohorts of larvae at WCH...

Seagrasses as Potential Chemical Refugia for Acidification-Sensitive Bivalves

Creator:: Smith, Stephanie Rae
Abstract:: As the effect of ocean acidification (OA) on marine calcifiers is better understood, a range of potential mitigative strategies have been proposed, many of which are plagued by concerns of scale and feasibility. One oft-cited option is to increase the biomass of photosynthetic organisms to remove CO₂ from the water...
