Abstract:

This study assessed links between host fitness, environmental change and opportunistic parasite infections in a dynamic estuary system. The Hawkesbury River in New South Wales is the most recent Sydney rock oyster growing area to experience outbreaks of infectious QX disease. This area was used to examine a relationship between the intensity of QX disease and inhibition of the oyster immune system. Oysters were grown at various sites along the river and periodically monitored for general condition, total haemolymph protein content, antibacterial capacity and phenoloxidase activity. Phenoloxidase activity was significantly inhibited during a key period of Marteilia sydneyi infectivity in late summer 2005. The degree to which phenoloxidase was inhibited strongly correlated with the intensity of M. sydneyi infection. The data suggest that the presence of some transient environmental stressor may have affected phenoloxidase activity during a key period of infection and increased the susceptibility of oysters to disease. These results provide further evidence for a specific relationship between decreased phenoloxidase activity and susceptibility to QX infection.

Abstract:

Adult Sydney rock oysters (Saccostrea commercialis) and Pacific oysters (Crassostrea gigas) were kept on commercial oyster leases at three intertidal sites in Port Stephens, New South Wales, and subtidally under an experimental raft at a fourth site between July 1988 and September 1989. Oysters were sampled from each site at approximately monthly intervals for chemical and histological analysis. Condition index and percentage glycogen of Pacific oysters were higher than those of Sydney rock oysters during winter and spring but tended to be lower during summer and autumn. Gonads of Pacific oysters matured two months earlier than those of Sydney rock oysters, with spawning being observed at all sites in October. Sydney rock oysters spawned later during December-January and did not lose as much condition after spawning as Pacific oysters. The absolute amount of glycogen in the meats of both species dropped at the expense of protein and lipid as the oysters became fully ripe. For both species, general condition of the oysters was best when they were grown subtidally under the raft, although both species were badly affected by invasion of the protistan parasite Mikrocytos roughleyi at this site. Poorest overall condition for both species occurred at a site (Karuah River) that experienced decreased salinities and increased turbidity after rain. Highest condition indices were found in Sydney rock oysters, at the site most dominated by coastal conditions (Corrie Island).

Abstract:

Tributyltin (TBT) concentrations have been measured in the tissue of the Sydney rock oyster Saccostrea commercialis sampled from estuaries in New South Wales, Australia. Background TBT levels of below 2 ng Sn g-1 contrasted with values between 80 and 130 ng Sn g-1 in oysters exposed to high boat densities or poor tidal flushing. Shell deformities and reduced tissue weights were associated with all samples displaying elevated TBT levels. Specimens of the Pacific oyster, Crassostrea gigas, growing on the same racks displayed 2-3 times the TBT concentrations of S. commercialis.

Full text

Abstract:

An indirect fluorescent antibody test (IFAT) was developed to test for mature and immature stages of Marteilia sydneyi in the digestive gland of the Sydney rock oyster, Saccostrea commercialis. Immunogold labelling of sections for electron microscopy showed that the sporont membrane, refringent granules, spore wall and haplosporosomes were particularly antigenic. The antibody did not react with any myxosporidean parasite found in local fish. Large numbers of sporonts were shed by infected oysters before oyster death. Lightly infected oysters were apparently able to shed all of their parasites and recover. Refringent granules were proteinaceous and an unlikely energy source for the shed parasite. Growth of the sporont was associated with the enlargement and production of refringent granules. The findings implicate filter-feeding or detritivorous invertebrates rather than scavenging invertebrates or fish in the life cycle of Marteilia parasites.

Full text

Abstract:

This study tested the proteomic responses of three spatially distinct Sydney rock oyster populations to elevated pCO2. Oysters were collected from environmentally different sites, two chronically affected by acid sulfate soil. Oysters from each of the three populations were exposed to ambient (380µatm) or elevated (856 and 1500µatm) pCO2 for 4 weeks. Subsequent proteomic analysis from haemolymph revealed that (1) there were differences between the proteomes of the three populations after exposure to ambient pCO2, and (2) the different oyster populations mounted significantly different responses to elevated pCO2. Proteins that differed significantly in concentration between pCO2 treatments fell into five broad functional categories: energy metabolism, cellular stress responses, the cytoskeleton, protein synthesis and the extracellular matrix. This is consistent with the hypothesis that environmental stress in oysters leads to a generic response involving increased mitochondrial energy production to maintain cellular homeostasis. Proteins involved in the cytoskeleton and energy metabolism were the most differentially expressed and were seen in all three oyster populations. Differences between populations in their proteomic responses suggested that the local environments from which oysters originate may affect their capacity to respond to ocean acidification.

Full text

Abstract:

With urbanisation, there is an increasing trend for artificial structures, such as seawalls, to replace natural habitats. The predatory mulberry whelk, Morula marginalba Blainville, is seldom observed on seawalls in Sydney Harbour, yet it is abundant on the rocky shores of south-eastern Australia. The Sydney rock oyster, Saccostrea glomerata Gould, is common on seawalls in Sydney Harbour, forming two types of crust, providing ‘elaborate’ or ‘simple’ habitats that differ in structure. Whelks were numerous on some seawalls with elaborate oyster crusts, but were sparse on walls with simple crusts. Thus, different types of crust, with different structure, may explain the differences in the numbers of whelks among seawalls. These different crusts may cause differences in dispersal and/or mortality. The structure of the habitat created by the oysters was manipulated on seawalls and the responses of M. marginalba were observed. Whelks emigrated more rapidly from simple than from elaborate crusts and more individuals moved into elaborate than into simple crusts. Decreases in the numbers of M. marginalba at larger scales, via mortality or emigration, did not differ between the crust types. The range of habitats that can be used by M. marginalba is extended because it can exploit the biogenic structure provided by oysters on artificial urban structures, which otherwise form unsuitable habitat.

Full text

Abstract:

Estimates of the ecological and economic value of ecosystems can provide important information for the prioritisation of conservation and restoration actions. Oyster reefs that were once common in temperate coastal waters have now been largely degraded or lost. Oyster reefs provide a suite of ecological services, including habitat and a food supply for a range of other species. In Australia, there is growing interest in oyster reef restoration, but there are knowledge gaps with regard to their structure and habitat value. Here, we describe the structure of eight remnant Sydney rock oyster (Saccostrea glomerata) reefs and estimate the density, biomass, productivity and composition of mobile macroinvertebrate and infaunal communities associated with them. The oyster reefs had a distinct assemblage of macroinvertebrates, with fivefold higher density of larger (≥2mm) macroinvertebrates, fivefold higher biomass and almost fivefold higher productivity, than that of adjacent bare sediments. The productivity of infaunal communities was twice as high under oyster reefs than in adjacent bare sediments. Therefore, S. glomerata reef restoration is likely to provide important habitat for macroinvertebrate communities and boost local secondary production.

Abstract:

This research honours the Baludarri (Sydney Rock Oyster). It is interdisciplinary in its approach and showcases the work of Australian born artist, Sarah Jane Moore. It presents key findings from an artistic residency at UNSW in Sydney, Australia, through the modalities of image, song and text. It highlights the importance of the humble oyster and maps an art-meets-science approach where Moore’s creative thinking seeks inspiration from her relationship with the work of an Indigenous scientist, Laura Parker. The oyster is Moore’s living data and the work maps the deep listenings necessary to foster communities that value reefs, hold oceans as sacred and regard the oyster as a precious entity to be celebrated, protected and nourished.

Abstract:

Proliferation of species introduced for aquaculture can threaten the ecological and economic integrity of ecosystems. We assessed whether the non-native Pacific oyster, Crassostrea gigas, has proliferated, spread and overgrown native Sydney rock oysters, Saccostrea glomerata, in Port Stephens, New South Wales (NSW), Australia, following the 1991 decision to permit its aquaculture within this estuary. Sampling of seven rocky-shore and four mangrove sites immediately before (1990), immediately after (1991–1992) and nearly two decades after (2008) the commencement of C. gigas aquaculture did not support the hypotheses of C. gigas proliferation, spread or overgrowth of S. glomerata. The non-native oyster, uncommon immediately before the commencement of aquaculture, remained confined to the inner port and its percentage contribution to oyster assemblages generally declined over the two decades. C. gigas populations were dominated by individuals of <40-mm shell height, with established adults being rare. Only at one site was there an increase in C. gigas abundance that was accompanied by S. glomerata decline. The failure of C. gigas in Port Stephens to cause the catastrophic changes in fouling assemblages seen elsewhere in the world is likely to reflect estuarine circulation patterns that restrict larval transport and susceptibility of the oysters to native predators.

Abstract:

Marine diseases represent a significant threat to wild organisms and the ecosystem services they support, yet studies often consider only disease impacts to aquaculture. In eastern Australia, the Sydney rock oyster (Saccostrea glomerata) aquaculture industry is increasingly affected by outbreaks of QX disease caused by parasitic Marteilia sydneyi. The present study considered impacts of M. sydneyi infection on the structure of wild-oyster populations that are dominated by S. glomerata, but that may also include the non-native Pacific oyster, Crassostrea gigas. In the Hawkesbury River Estuary, where cultured S. glomerata has experienced up to 98% QX-induced mortality, we found that disease prevalence was comparatively low among wild S. glomerata, peaking at 14%, and annual infections did not cause seasonal patterns of mortality. Furthermore, C. gigas, a competitor of S. glomerata that is not susceptible to QX disease, was not consistently more abundant at sites with than without the parasite. Overall, our results indicated that relative to cultured counterparts, wild S. glomerata in the Hawkesbury River Estuary is minimally affected by QX disease. Nevertheless, our study showed that diseases of aquaculture stocks have the capacity to infect wild populations, and that longer-term assessment of wild populations at risk is essential.

Abstract:

Larvae are a critical dispersal stage of marine invertebrates, and their survival depends on nutrition and energetics. This study compared the size, survival, metabolic rate and egg and larval lipid class profiles of larvae of the endemic Sydney rock oyster Saccostrea glomerata and the invasive Pacific oyster Magallana gigas through a period of starvation for 5 and 9 d after fertilisation. Starved larvae grew without food until 5 d of age, at which point they stopped developing, but resumed growth when fed. Egg lipids profiles comprised 78.1 and 74.5% triacylglycerol for M. gigas and S. glomerata respectively. When fed, larvae of M. gigas were significantly larger in size and had faster growth and similar survival compared to S. glomerata. When starved, larvae of M. gigas and S. glomerata grew at similar rates, and there was a trend for lower survival of M. gigas. Larval endogenous lipid reserves were deleted in the first 24 h. Larvae of M. gigas had more total lipids and comparatively more diacylglycerols, monoacylglycerols, phospholipids and cholesterol, whereas S. glomerata had more diacylglycerols and produced sterol esters. Starvation altered the patterns of lipid assimilation, and metabolic rates of larvae of M. gigas and S. glomerata differed over time. When starved, S. glomerata larvae had greater capacity to cope with starvation compared to M. gigas, perhaps due to an evolutionary history in oligotrophic estuaries. As the climate rapidly changes in this global climate-change hotspot, S. glomerata is likely to be negatively affected.

Abstract:

Whether sex determination of marine organisms can be altered by ocean acidification and warming during this century remains a significant, unanswered question. Here, we show that exposure of the protandric hermaphrodite oyster, Saccostrea glomerata to ocean acidification, but not warming, alters sex determination resulting in changes in sex ratios. After just one reproductive cycle there were 16% more females than males. The rate of gametogenesis, gonad area, fecundity, shell length, extracellular pH and survival decreased in response to ocean acidification. Warming as a sole stressor slightly increased the rate of gametogenesis, gonad area and fecundity, but this increase was masked by the impact of ocean acidification at a level predicted for this century. Alterations to sex determination, sex ratios and reproductive capacity will have flow on effects to reduce larval supply and population size of oysters and potentially other marine organisms.

Full text

Abstract:

Studies of long-term exposure to multiple stressors on predator–prey interactions are necessary to determine the effect of coastal degradation on organisms that have had generations to adapt and acclimate to change. In New South Wales, Australia, a natural gradient of multiple stressors produced by acid sulfate soil effluent was used to determine the impact of exposure to multiple stressors on predator–prey dynamics between mud crabs Scylla serrata and Sydney rock oysters Saccostrea glomerata. Wild oysters were collected from two polluted and two reference sites that varied in their distance away from a flood gate that acted as a point source of water with low salinity, low pH and low alkalinity. Oysters from sites affected by multiple stressors and those from reference sites were offered to mud crabs in 48-h laboratory no-choice feeding trials. Oysters from affected sites had lower mortality than those from a reference site that was farthest from the source of polluted water. Linear models containing distance from flood gate best explained oyster mortality. Differences in rates of mortality were due to the decreased time crabs spent foraging on affected oysters. Long-term exposure to acid sulfate soil effluent alters trophic dynamics between predators and prey, which may have consequences for coastal food webs.

Abstract:

Abstract Marine historical research has made progress in bridging the gap between science and policy, but examples in which it has been effectively applied remain few. In particular, its application to aquaculture remains unexplored. Using actual examples of natural resource management in the state of South Australia, we illustrate how historical data of varying resolution can be incorporated into aquaculture planning. Historical fisheries records were reviewed to identify data on the now extinct native oyster Ostrea angasi fishery throughout the 1800 and early-1900s. Records of catch, number of boats fishing, and catch per unit effort (cpue) were used to test fishing rates and estimate the total quantity of oysters taken from select locations across periods of time. Catch quantities enabled calculation of the minimum number of oysters per hectare for two locations. These data were presented to government scientists, managers, and industry. As a result, interest in growing O. angasi increased and new areas for oyster aquaculture were included in regulatory zoning (spatial planning). Records of introductions of the non-native oyster Saccostrea glomerata, Sydney rock oysters, from 1866 through 1959, were also identified and used to evaluate the biosecurity risk of aquaculture for this species through semi-quantitative risk assessment. Although applications to culture S. glomerata in South Australia had previously been declined, the inclusion of historical data in risk assessment led to the conclusion that applications to culture this species would be accepted. The examples presented here have been effectively incorporated into management processes and represent an important opportunity for the aquaculture industry in South Australia to diversify. This demonstrates that historical data can be used to inform planning and support industry, government, and societies in addressing challenges associated with aquaculture, as well as natural resource management more broadly.

Abstract:

ABSTRACTVibrio parahaemolyticusis an indigenous bacterium of marine environments. It accumulates in oysters and may reach levels that cause human illness when postharvest temperatures are not properly controlled and oysters are consumed raw or undercooked. Predictive models were produced by injecting Pacific oysters (Crassostrea gigas) with a cocktail ofV. parahaemolyticusstrains, measuring viability rates at storage temperatures from 3.6 to 30.4°C, and fitting the data to a model to obtain parameter estimates. The models were evaluated with Pacific and Sydney Rock oysters (Saccostrea glomerata) containing natural populations ofV. parahaemolyticus. V. parahaemolyticusviability was measured by direct plating samples on thiosulfate-citrate-bile salts-sucrose (TCBS) agar for injected oysters and by most probable number (MPN)-PCR for oysters containing natural populations. In parallel, total viable bacterial counts (TVC) were measured by direct plating on marine agar. Growth/inactivation rates forV. parahaemolyticuswere −0.006, −0.004, −0.005, −0.003, 0.030, 0.075, 0.095, and 0.282 log10CFU/h at 3.6, 6.2, 9.6, 12.6, 18.4, 20.0, 25.7, and 30.4°C, respectively. The growth rates for TVC were 0.015, 0.023, 0.016, 0.048, 0.055, 0.071, 0.133, and 0.135 log10CFU/h at 3.6, 6.2, 9.3, 14.9, 18.4, 20.0, 25.7, and 30.4°C, respectively. Square root and Arrhenius-type secondary models were generated forV. parahaemolyticusgrowth and inactivation kinetic data, respectively. A square root model was produced for TVC growth. Evaluation studies showed that predictive growth forV. parahaemolyticusand TVC were “fail safe.” The models can assist oyster companies and regulators in implementing management strategies to minimizeV. parahaemolyticusrisk and enhancing product quality in supply chains.
