▼ Fisheries Laboratory during 1952, in the rearing of the native Pacific Coast oyster, Ostrea lurida Carp., in small containers. The decline of the oyster fishery in Yaquina Bay, Oregon, has been attributed in part to the lack of adequate spat-falls. Investigations were begun in 1947 to devise methods of artificially rearing oyster larvae under controlled conditions which might later be extended in producing seed oysters in adequate numbers for the commercial production of the native oyster. Adult oysters from which larvae were obtained for the rearing tests were Longed from the native oyster beds near Oysterville on Yaquina Bay. The larvae were taken from the adult oyster by two methods. The adult oysters were placed in five-gallon wide-mouth jars and the temperature raised to 200 C. until natural swarming occurred, or the adult oysters were opened manually and the larvae were taken from the gravid oysters. These methods apply during the natural spawning season of the native oyster which occurs in late spring and summer. The rearing containers used were five-gallon wide-mouth jars and 12-gallon crocks. The larger containers gave better results. A filtering device was installed in each container to accomplish the water change without loss of larvae. A rearing temperature of 18 to 200 C. was maintained by controlling the room temperatures. All salt water used in rearing experiments was sand filtered to remove organisms that may prey on the larvae or take food in competition with them. Larval food consisted of plankton which measures less than 9 microns. These organisms were cultured in small containers and 25 ml. of the media was introduced into the rearing containers every 48 hours. Rearing containers with various larval concentrations received the same amount of media and the results showed no indications of over or under feeding. A salinity range of 26 to 32 parts per thousand yielded satisfactory results. The upper and lower limits were not determined. When the bay salinity exceeded 34 parts per thousand, the salinity was reduced by adding fresh water. This resulted in larval mortality. The reason for this mortality was not determined but it is possible that the fresh water used was toxic. The water in the rearing containers was changed every other day in the early experiments. A less frequent water change was tried which yielded satisfactory results. A water change once or twice during the larval free-swimming period appears to be adequate. The larval growth rate was measured and a daily growth of 4 to 5 microns is considered satisfactory. The rate of growth appears to be a reliable indication of the condition of the larvae. The larvae set out on a cultch after a 15 to 25 day free-swimming period. Setting began when the larvae measured about 260 microns. The spat received the same care as the free-swimming larvae and considerable 2 shell growth was evident. During the winter months, induced spawning was investigated. Adult oysters were taken from the bay and held in the laboratory at a temperature of 18 to… Advisors/Committee Members: Dimick, Roland E. (advisor).

▼ A series of factorial experiments were conducted using eyed oyster larvae (Crassostrea gigas) reared at a commercial hatchery in Netarts, Oregon. The objectives of the study were to obtain the highest percentage of setting larvae and the best survival of the spat. Experiments on the combined effects of temperature and salinity indicated that temperature had a highly significant effect on the setting of Pacific oyster larvae. For temperatures ranging from 15°-30°C, the percentage of larvae setting during a 48-hour period increased as temperature increased. There was no significant difference in setting for salinities ranging from 15-30 ppt. In one setting experiment with Kumomoto larvae (a different variety of C. gigas), the differences among the sixteen combinations of temperature and salinity were statistically insignificant. Feeding larvae 120,000 cells per milliliter of the alga Pseudoisochrysis paradoxa did not significantly improve setting during a 48-hour period, and in one experiment temperature and feeding interacted to the detriment of setting. There was no significant difference in the percentages of attaching larvae when oyster, cockle, or butter clam shells were used as substrates. Dipping oyster or butter clam shells in an aqueous extract of oyster tissue improved setting, but the presence of the extract did not improve setting on razor or littleneck clam shells. Storing eyed larvae at 5°C for several days before setting them appeared to increase the percentage of attaching larvae. The best temperature for setting stored larvae was 25°C. Oyster larvae that attached to shell cultch during the setting experiments were held in a tank of raw seawater in the laboratory. After eight to nine months, the percentages of surviving spat were calculated. Survival was poor for larvae set at 15°C, and there was some evidence of higher mortality among larvae stored for several days before being set. Because of the laboratory conditions, these studies may not have provided a realistic measure of spat survival under natural conditions, and field studies should be carried out to confirm these results.

▼ Norovirus (NoV) is the principal cause of viral gastroenteritis in the United States. It has been linked to filter-feeding molluscan shellfish, that bioaccumulate the virus from contaminated surrounding waters. The consumption of raw or undercooked contaminated oysters may result in acute gastroenteritis. We investigated the occurrence of NoV GI and GII and microbial indicators of fecal contamination in oysters and harvesting water from areas along the Louisiana Gulf Coast. We developed a filtration and concentration method for the detection of NoV from oyster harvesting waters. Lastly, this body of work compares commonly used molecular techniques (RT-PCR) and a commercial enzyme immunoassay for the detection of NoV. One oyster sample was positive for norovirus GII at 3.5 ± 0.2 log10 genomic equivalent copies/g digestive tissues, however the surrounding water tested negative for NoV. Zeolite granules were used for the filtration of norovirus-seeded waters. Beef Extract (10%) in McIlvaine’s buffer was the optimal elution buffer resulting in an average percent recovery of 41.76 + 0.07 (p<0.05). Artificial and environmental waters with 20ppt salt had an observed average percent recovery of 40.79 + 0.19 and 18.95 + 0.24, respectively which was significantly higher than 0, 5, 10, 15, and 25ppt (p<0.05). The observed percent recoveries for artificial and environmental waters were 44.03 + 0.20 and 34.36 + 0.02, respectively. The percent recovery for artificial and environmental water using TaqMan® Fast Virus 1-Step RT-qPCR was 38.85% + 0.27 and 19.77% + 0.07, respectively. In comparison, SuperScript® III Platinum One-Step qRT-PCR exhibited an average percent recovery of 11.12% + 0.183 and 15.55% + 0.225 for artificial and environmental waters. The EIA assay assay was not sensitive enough to detect NoV in the elution samples despite RT-qPCR methods quantifying the virus concentration between 104 and 105 genomic copies/ml. As such, it is not an effective method for the detection of NoV from environmental water matrices without RT-qPCR as a secondary validation method. This body of work provides an effective method to detect norovirus in oyster harvesting waters. Our results emphasize the need for regular monitoring of pathogenic viruses in oyster harvesting areas to reduce viral gastroenteritis incidences.

Pearl oyster farming is a significant component of the Australian mariculture industry. However, disease often threatens its productivity. Previous work has identified a strong relationship between environmental stress and altered immunological activity in many molluscs, often resulting in the spread of opportunistic pathogens. My studies investigate this relationship, focusing on the effect of stress induced neuroendocrine secretions. – The First Chapter provides a general introduction to the history and existing knowledge of Akoya pearl oyster aquaculture. This Chapter examines subjects that are to be further investigated by this thesis, namely; the relationship between farmed marine invertebrates and the influence of husbandry and handling on their immune and endocrine systems. – The Second Chapter provides a detailed introduction of the morphology and cytochemistry of P. imbricata haemocytes; granulocytes, hyalinocytes, and serous cells. Granulocytes represent the most abundant cells type (62%), and are shown to have the highest capacity to phagocytose Congo red-stained yeast cells. Granules contained within granulocytes were also found to stain positively for a number of immuno-reactive enzymes or products including; phenoloxidase (PO), peroxidase, superoxide, and melanin. Hyalinocytes were the second most abundant cell type (36%), and also engulfed Congo red-stained yeast cells. Serous cells represented the smallest component of the haemocyte population (2%) and were not involved in clearance activities. – Chapter Three investigates the effects of common environmental stressors (low salinity, mechanical agitation (MA), and exposure to air) on the immunological activity in P. imbricata haemocytes. Both phagocytosis and PO activity decreased significantly when oysters were exposed to all three stressors. The responses to other parameters tested (granulocyte to hyalinocyte ratio, total haemocyte counts, acid phosphatase activity, and total protein content) were found to vary, and the different immunological parameters tested were influenced uniquely according to the type of stressor. – Chapter Four addresses the relationship between stress and hormone-induced apoptosis in defensive haemocytes from P. imbricata. Haemocytes were exposed to 0.0, 2.5, 5.0…

The Eastern Oyster (Crassostrea virginica) once played a pivotal ecological role in Virginia waters and the Chesapeake Bay. However, unregulated over-harvesting, combined with reduced water quality and disease, has caused a drastic decline in oyster populations, such that present day levels are less than 2% pre-harvest populations. Restoration efforts, currently underway to re-establish healthy oyster populations, are focused on rehabilitating benthic habitat to be suitable for natural oyster larval recruitment and growth. The goal of this study was to understand the hydrodynamics involved in fluid and sediment transport over reefs, and how these dynamics may impact larval transport to healthy and restored reef areas.

Velocity and turbulence data was collected off of the Eastern shore of Virginia over multiple benthic surfaces including a mud flat, a healthy reef, and two restoration sites comprised of either fossil oyster or whelk shell. Reynolds stresses, shear velocity, u*, and drag coefficients, CD, were computed and due to the extreme roughness of the reef, mean estimates of u* over a healthy reef were found to be 47% greater than those found over a restoration site. Enhanced shear increased both turbulent mixing and drag above the reef, but within the interstitial areas between individual oysters, mean velocities and turbulent otions were reduced. CD, used as a measure of roughness, also increased with elevation on the healthy reef.

Small-scale hydrodynamic forces were studied in an open-channel, recirculating, water flume along benthic roughnesses of varying height and spacing, used to mimic variability found on the reef. Drag and lift forces within the structure decreased with increasing height and increased with increased spacing. Geometrically similar slate tile structures were deployed in the field over a five month period, and the greatest larval recruitment corresponded closely to locations where drag and lift forces were reduced. The combined field and laboratory data suggests that restoration efforts should consider both elevation and bed roughness similar to those found on healthy oyster reefs, to provide suitable hydrodynamic conditions that promote larval recruitment, prevent burial by sediment, and may provide some refuge from predation.

▼ 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 United States. In order to reduce the high risks of V. parahaemolyticus infection associated with raw oyster consumption, post-harvest processes capable of decreasing V. parahaemolyticus levels by >3.52 log MPN/g are recommended by the U.S. Food and Drug Administration for oyster processing upon harvest. Depuration is a process of holding shellfish in clean seawater allowing shellfish to purge contaminants and may be applied by the shellfish industry as a post-harvest process to reduce contamination of V. parahaemolyticus in oysters. Currently, depuration at controlled temperatures between 7 and 15°C for 5 days has been developed to achieve >3.0 but <3.52 log MPN/g reductions of V. parahaemolyticus in oysters. The aim of this study was to investigate the factors, including water pH value, water temperature and oyster to water ratio, affecting the efficacy of depuration in decreasing V. parahaemolyticus in oysters and to improve the efficacy of depuration process to achieve >3.52 log MPN/g reductions of V. parahaemolyticus in oysters for application as a post-harvest treatment of oysters by the shellfish industry to produce safe oysters for raw consumption. Studies of growth of V. parahaemolyticus in trypticase soy broth with 2% salt (TSB-Salt) medium of various pH values (5.5, 7.3 and 9.0) found that growth of five clinical V. parahaemolyticus strains were retarded in TSB-Salt at pH 5.5 compared with at pH 7.3 or 9.0. Investigation of oyster gaping in artificial seawater (ASW) of different pH values ranging from 4.0 to 10.5 unveiled that oysters survived well in ASW of pH between 5.0 and 9.5 at room temperature. Based on these findings, oyster depuration was conducted in a lab-scale depuration system with pH value of ASW being controlled at 5.5 or 7.0 at 12.5°C or 20°C for 5 days with an initial V. parahaemolyticus level in oysters of 10⁴⁻⁵ MPN/g. Depuration with ASW (pH 8.3) without control of pH value was used as a control. Depuration in ASW of pH 5.5, 7.0 and 8.3 at 20°C for 5 days resulted in 0.7-2.0, 1.7-2.0 and 2.8 log MPN/g reductions of V. parahaemolyticus, respectively. Greater reductions (1.6-2.1 log MPN/g at pH 5.5, 2.9-3.0 log MPN/g at pH 7.0 and 3.5 log MPN/g at pH 8.3) of V. parahaemolyticus in oysters were observed after depuration with ASW at 12.5°C for 5 days. Decreasing pH value of ASW for depuration resulted in decreased efficacy of the process in reducing V. parahaemolyticus contamination in oysters. Study of effects of different oyster to water ratios (number of oyster : volume of water) of 1:1, 1:1.5, 1:2, and 1:2.5 revealed that depuration with oyster to water ratio of 1:2 could achieve >3.52 log MPN/g reductions after four days.

▼ Oysters are ecologically and economically important shellfish that have a complex life cycle involving several critical processes such as larval calcification and metamorphosis. Rising anthropogenic CO2 levels that cause ocean warming and ocean acidification are predicted to make coastal and surface oceans increasingly unsuitable for several calcifying marine invertebrates including oysters. Simultaneously, climate change-induced heavy precipitation in some parts of the world is expected to reduce ocean surface salinity. These multiple climate change stressors may not only reduce the calcification rate of marine calcifying species but also depress their metabolism. The impact of future climate change on the sensitive processes involved in the oyster’s complex life cycle, particularly metamorphosis, could be a bottleneck for population recruitment success. For example, in the U.S., oyster aquaculture is already failing to produce seeds due to climate change, providing evidence that oyster recruitment and populations may not be sustainable in future oceans. This is a stark warning to China, not only as a centre of oyster biodiversity, but also as the main producer of >80% of the world’s oysters. To avoid the possibility of future socioeconomic crisis and seafood insecurity, we need to assess how commercially important oyster species can tolerate future climate conditions. Therefore, the primary goal of this thesis is to understand how multiple climate change stressors, interactively and individually, can affect the economically and ecologically important edible oyster species, the Pacific oyster, at developmental, physiological, and molecular levels. The results demonstrated that long-term ocean acidification and exposure to multiple climate stressors had varying effects on the multiple life stages of larvae of the Chinese Pacific oyster. By analyzing multiple physical parameters (larval growth, respiration and feeding efficiency during metamorphosis, energy reserve for growth, metamorphosis success, early juvenile growth, shell composition and ultrastructure) and using multiple “omics” technologies (metabolomics and proteomics), we demonstrated the Chinese Pacific oyster had considerable tolerance and resistance to future moderate multiple stressor scenarios. Pacific oyster larvae when exposed to reduced seawater salinity and decreased pH appeared to be able to maintain an osmotic balance by shifting structural and storage lipid energy reserves, producing extra energy via saturated fatty acids, and homeoviscous adaptation. Similarly, larvae appeared to have adequate short-term proteomic plasticity to mitigate the negative effects of decreased pH by shifting energy forms, or by taking advantage of increased metabolic activity under elevated temperature. Larvae were also able to activate important ion channel protein NA+/H+ exchange regulatory cofactor NHE-RF1 to balance the cellular acid-base equilibrium in response to decreased pH. Moreover, wide alterations in the proteome, such as downregulated proteins involved…

▼ Oysters can be easily contaminated with spoilage and pathogenic bacteria through contaminated waster. The United States produces more than 27 million pounds of oysters each year and most of them are sold and consumed raw without further processing. Growth of naturally contaminating bacteria in oysters during storage results in loss of quality and product value. Contamination of pathogenic bacteria such as Vibrio parahaemolyticus and Vibrio vulnificus in oysters is also a safety concern of the industry and consumers. The traditional depuration process for reducing bacterial contamination in oysters using clean seawater has been reported to be ineffective in reducing Vibrio contamination in oysters. This study investigated effects of electrolyzed oxidizing (EO) water treatment on reducing both V. parahaemolyticus and V. vulnificus contamination in oysters. Freshly harvested Pacific oysters were inoculated with 5-strain cocktail of V. parahaemolyticus or V. vulnificus at levels of 10⁴ and 10⁶ MPN/g. Inoculated oysters were held in EO water (chlorine: 30 ppm, pH: 2.82, ORP: 1131 mV) containing 1% NaCl at room temperature. Reductions of V. parahaemolyticus and V. vulnificus in oysters during the treatment were determined at 0, 2, 4, 6, and 8 h. EO water containing 30 ppm of chlorine was found to exhibit strong bactericidal effects against pure cultures of V. parahaemolyticus and V. vulnificus (>6.6-log reductions in 15s). Holding oysters inoculated with V. parahaemolyticus or V. vulnificus in EO water (30 pin chlorine) containing 1% NaCl for 4-6 h resulted in significant reductions of V. parahaemolyticus and V. vulnificus by 1.13 and 1.05 log MPN/g, respectively. However, extended exposure (>12 h) of oysters in EO water containing high levels of chlorine (>30 ppm) was found to be detrimental to oysters. EO water could be used as a post-harvest treatment to reduce Vibrio contamination in oysters. However, treatment should be limited to 4-6 h to avoid death of oysters. Further studies are needed to determine effects of EO water treatments on sensory characteristics of treated oysters. Advisors/Committee Members: Su, Yi-Cheng (advisor).

▼ This study was designed to determine the survival of Vibrio parahaemolyticus in salted oysters as prepared in Korea. Three levels of salt concentration were included; 3.0%, 6.8%, and 10.6% of the weight of the raw oysters. Two methods were used to inoculate the products, surface-inoculation and injection into the oysters, which were then held at 18°C. Multiplication of V. parahaemolyticus (Japanese strain T-3765-1) did not occur in the salted oysters, except for a slight increase in numbers after 24 hours from surface-inoculated samples with 3.0% salt and all samples of injected oysters. The samples with the higher salt concentrations showed longer survival of the organisms. Numbers of survivors in surface-inoculated oysters were markedly reduced within three days; the samples of injected oysters did not show reduced numbers in this period. There were more survivors from the injected samples over the storage period than from the surface-inoculated samples. No viable cells were observed after seven days from the surface-inoculated samples with 3.0% salt and the injected samples with 3.0% salt, after eight days from the surface-inoculated samples with 6.8% salt, after nine days from the injected samples with 6.8% salt, and after 11 days from the injected samples with 10.6% salt. A small number of V. parahaemolyticus were recovered from the surface-inoculated samples with 10.6% salt after eight days, the last testing period for these samples. The results of pH measurement suggested that the samples with higher salt concentration may have prolonged survival of V. parahaemolyticus through the effect of the higher pH value. An analysis of variance revealed a significant difference (5% level) in recovery between a modified isolation medium (Twedt and Novelli) and thiosulfate-citrate-bile salts-sucrose agar. Salt concentrations of 3.0%, 6.8%, and 10.6% slightly reduced the total bacterial counts after three days from the two lots of oysters used for the surfaceinoculated samples and further reduction was observed after seven days; reduction in numbers was not detected within 8 or 11 days from the two lots used for the injected samples. The latter two lots had much lower plate counts at the beginning of the experiment. No relationship was found between pH and total bacterial counts on the salted oysters.

1. General introduction – 2. Double stranded RNA is processed differently in two oyster species – 3, Two oyster species that show differential susceptibility to virus infection also show differential proteomic responses to generic dsRNA – 4. SWATH mass spectrometry analysis of oyster tissues reveals the actvation of TLR signalling, cytokine production and apoptotic pathways in response to dsRNA challenge: implications for host resistance to virus infections – 5. General discussion.

The aquaculture industry faces challenges and major economic losses from infectious disease outbreaks of farmed stocks. Ostreid herpes virus type 1 (OsHV-1 μvar) infection of larval and juvenile Pacific oysters is a worldwide phenomenon. This thesis investigates responses to exogenous double stranded RNA (dsRNA) in two oyster species that are farmed extensively in Australia - the Pacific oyster (Crassostrea gigas) and Sydney rock oyster (Saccostrea glomerata). dsRNAs are products of viral infection and in many biological systems, dsRNA provokes strong immune responses. While C. gigas is susceptible to viral infection, S. glomerata appears to be resistant. This study examines molecular basis for the differential susceptibility to OsHV-1 infection using state-of-the-art mass spectrometry (iTRAQ and SWATH) proteomics, transcriptomics and fluorescence microscopy techniques. This is the first comparative study of the immune systems of two oyster species that behave differently to OsHV-1 and also provides the proteome map of the Sydney rock and the Pacific oysters.

Both oyster species were capable of detecting exogenous dsRNA, but differed in the patterns of double stranded RNA uptake and processing, as well as in their proteomic responses to that perturbation. Gill tissues are an important site of dsRNA processing and response. In response to dsRNA, Sydney rock oysters activated cellular signalling pathways, as well as apoptotic (cell death) pathways, that are typical of antiviral responses in metazoans. These responses were absent in the Pacific oysters. The data provides a useful model for further studies into resistance to viral infection in these oysters, as well as unravelling the molecular mechanisms that underpin the biological differences in viral susceptibility.

The increase in carbon dioxide emissions due to human activities has led to drastic variations in global climate. In addition to global warming and extreme weather patterns, the high CO2 levels have been leading to progressive ocean acidification. Compounded with other climate change related stressors, ocean acidification will hinder the ability of marine organisms to adapt to the ensuing changes and might affect human dependence on oceans as a source of food. Most marine organisms have complex life cycles, involving metamorphosis from larval to adult forms. In the early stages of life, oysters have calcium carbonate shells that are particularly sensitive to low pH, and the rapid climatic changes can compromise their metamorphosis. High temperature, low salinity and low pH resulting from ocean acidification are detrimental to both native and cultivated oyster populations. Although mechanistic studies to understand the tolerance responses of closely related species would be significant in this context, none have been reported to date. Therefore, this thesis aims to reveal the mechanisms that distinguish the “winners” from the “losers” among the selected aquatic species of commercial importance, in withstanding the stress induced by climate change. The present study employed molecular approaches to evaluate the interactive and cumulative effects of multiple stressors on large-scale cultures of pediveliger larvae from two oyster populations, Crassostrea hongkongensis and Crassostrea gigas. The study undertook transcriptomic and proteomic profiling of changes induced by ocean acidification in the larvae. The results revealed that oyster larvae could adopt an energy ‘trade-off’ strategy through metabolic suppression and adjust cell signalling pathways to overcome the stress induced by ocean acidification. Information from the oyster genome database facilitated the shotgun proteomics investigations on oyster larvae remarkably revealed over 1350 proteins in both the species. The study identified species- and stressor-specific tolerance responses, and survival mechanisms that preserved calcification, in oyster larvae. The larvae showed depletion of energy reserves due to enhanced metabolism, oxidative damage-induced immune response and metabolic suppression. The study reveals the existence of tolerance mechanisms in oysters that help them adapt to stresses resulting from climate change. It pioneered the use of a proteomics approach to understand the impact of multiple stressors on oyster larvae and the molecular mechanisms underlying their successful adaptation to them. Highlighted several potential possible biomarkers in this study will likely to play an important role in identifying oyster species showing heritable tolerance for future aquaculture.
