Mortalities also occurred in wild diploid C. gigas in the Georges River and shortly thereafter in the adjacent Parramatta River estuary upstream from Sydney Harbour. Neighbouring Saccostrea glomerata (Sydney rock oysters) did not experience mortalities in either estuary. Surviving oysters were collected to investigate the cause of mortalities. Histologically all oysters displayed significant pathology, and molecular testing revealed a high prevalence of ostreid herpesvirus-1 (OsHV-1). Quantitative PCR indicated that many C. gigas were carrying a high viral load at the time of sampling, while the load in S. glomerata was significantly lower (p & 0.001). Subsequent in situ hybridisation experiments confirmed the presence of a herpesvirus in C. gigas but not S. glomerata tissues, suggesting that S. glomerata is not susceptible to infection with OsHV-1. Naïve sentinel triploid C. gigas placed in the Georges River estuary in January 2011 quickly became infected and experienced nearly 100% mortality within 2 wk of exposure, indicating the persistence of the virus in the environment. Phylogenetic analysis of sequences derived from the C2/C6 region of the virus revealed that the Australian strain of OsHV-1 belongs to the microvariant (μ- var) cluster, which has been associated with severe mortalities in C. gigas in other countries since 2008. Environmental data revealed that the Woolooware Bay outbreaks occurred during a time of considerable environmental disturbance, with increased water temperatures, heavy rainfall, a toxic phytoplankton bloom and the presence of a pathogenic Vibrio sp. all potentially contributing to oyster stress. This is the first confirmed report of OsHV-1 μ-var related C. gigas mortalities in Australia. © Inter-Research 2013.]]> Wed 17 Oct 2018 13:20:23 AEST ]]> Current Status and Potential of Tropical Rock Oyster Aquaculture Wed 08 Jan 2020 11:55:48 AEST ]]> Acclimatory processes are likely responsible for metal tolerance in oyster embryos Wed 06 Sep 2017 11:11:27 AEST ]]> Aquatic zooremediation: deploying animals to remediate contaminated aquatic environments Tue 19 Sep 2017 14:32:53 AEST ]]> Pearl aquaculture - Profitable environmental remediation?

To overcome larval and spat mortality, the interactive effects of temperature and salinity on early life stages (embryos, larvae, and spat) of S. glomerata were investigated to optimize rearing conditions and thereby improve survival and growth. The early ontogenetic stages of S. glomerata were held at temperatures in the range from 16°C to 30°C and salinities in the range 10-35 ppt. Development of embryos to D-veliger larvae was significantly affected by temperature (P < 0.001), salinity (P < 0.001) and the interaction of these factors. Most rapid embryonic development occurred at a salinity and temperature of 35 ppt and 26°C. Growth of D-veliger, umbonate and pediveliger larvae was also significantly affected by salinity (P < 0.001) and temperature, as was the growth of spat. Salinity had a significant effect (P < 0.001) on D-veliger larvae and spat survival, whereas temperature had a significant effect (P < 0.001) on D-veliger and pediveliger survival. Survival and growth of umbonate larvae were not affected by either salinity or temperature within the range tested. Surface-response plots were also used to examine interactions between salinity and temperature. The optimal temperature for growth of D-veliger larvae was 28°C and for umbonate and pediveliger larvae was 30°C. Greatest length increases for D-veliger and umbonate larvae occurred at the maximum salinity level (34 ppt) whereas the salinity at which this occurred for pediveliger larvae was 26 ppt. Survival of larvae at these optima exceeded 95%. Best spat growth was at a salinity of 35 ppt and a temperature of 30°C. Spat survival at this salinity and temperature combination was 82%. Maximum spat survival was 93% and was measured at a temperature and salinity combination of 23°C and 30 ppt.]]> Thu 02 Nov 2017 15:39:53 AEST ]]> The changing face of oyster culture in New South Wales, Australia Thu 02 Nov 2017 15:31:27 AEST ]]> Larval settlement preference of a native bivalve: The influence of an invasive alga versus native substrata Thu 02 Nov 2017 15:25:56 AEST ]]> Assessment of QX and winter mortality disease resistance of mass selected Sydney rock oysters, Saccostrea glomerata (Gould, 1850), in the Hawkesbury river and Merimbula Lake, NSW Australia Thu 02 Nov 2017 15:18:55 AEST ]]> Ecotoxicological evaluations of common hatchery substances and procedures used in the production of sydney rock oysters Saccostrea glomerata (Gould 1850) Thu 02 Nov 2017 15:18:55 AEST ]]> Populations of the Sydney rock oyster, Saccostrea glomerata, vary in response to ocean acidification Mon 27 Jun 2016 10:02:49 AEST ]]> Latitudinal variation in reproductive behavior in the pearl oyster, Pinctada albina sugillata Mon 18 Sep 2017 15:43:22 AEST ]]> Diet and feeding regimens for larval doughboy scallops, Mimachlamys asperrima Mon 18 Sep 2017 15:26:52 AEST ]]> Spawning induction and fertilisation in the doughboy scallop Chlamys (Mimachlamys) asperrima Mon 18 Sep 2017 15:19:52 AEST ]]> Evaluation of alternative suspended culture methods for the commercial scallop, Pecten fumatus Reeve Mon 18 Sep 2017 14:58:52 AEST ]]> Hatchery production of diploid and triploid clams, Tapes dorsatus (Lamarck 1818): a potential new species for aquaculture Mon 18 Sep 2017 14:44:52 AEST ]]> Hatchery production for the venerid clam Katelysia rhytiphora (Lamy) and the Sydney cockle Anadara trapezia (Deshayes) Mon 18 Sep 2017 14:23:58 AEST ]]> Induction of anaesthesia in the commercial scallop, Pecten fumatus Reeve Mon 18 Sep 2017 14:02:52 AEST ]]> Detachment of commercial scallop Pecten fumatus, spat from settlement substrates 95% reattachment occurred within 24 h of all detachment methods tested. © 1994.]]> Mon 18 Sep 2017 13:55:52 AEST ]]> Effect of starvation on biological factors related to immunological defence in the Sydney rock oyster (Saccostrea glomerata) Mon 18 Sep 2017 11:35:53 AEST ]]> First breeding program of the Portuguese oyster Crassostrea angulata demonstrated significant selection response in traits of economic importance Mon 18 Nov 2019 14:37:30 AEST ]]> Salinity and temperature tolerance of embryos and juveniles of the pearl oyster, Pinctada imbricata Röding 70% of oysters formed byssal attachments to the aquaria walls within 6 h. Outside this narrow salinity range, the rate of byssal attachment decreased and ceased altogether at salinities of 17 ppt or less. Temperature also affected byssal attachment although the impacts were not as great as those of salinity. Within the optimal salinity range (29-32 ppt), the rate of byssal attachment was fastest at 18°C, where up to 80% of oysters had attached within 4 h. This rate was slightly greater than that observed at 22°C, which in turn exceeded those observed at 14 and 26°C. Salinity and temperature also affected survival. Irrespective of temperature, survival was high at salinities of 32 and 35 ppt. By contrast, high rates of mortality occurred within 7 days at salinities of 23 ppt or less. Onset of mortality was most rapid and overall mortality highest at the two extremes in temperature tested, 14 and 26°C. © 2004 Elevier B.V.

Across all sites, the GI had a strong, positive correlation with temperature (r ¼ 0.783; df ¼ 26; P <0.001) and a moderate, positive correlation with rainfall (r ¼ 0.496; df ¼ 31; P <0.05). Synchronization in spawning patterns occurred between sites, and gender ratios suggest that S. echinata is a dioecious species with low levels of functional hermaphroditism. The major finding of this study is that S. echinata spawns semicontinuously throughout the monsoon season (October–April) and has an extended resting phase throughout the dry season (May–September). The information generated in this study has a number of potential applications relating to the timing of broodstock collection and hatchery production, and it provides a broader basis for further developing S. echinata as a commercial aquaculture species.]]> Mon 06 Jan 2020 12:29:42 AEST ]]> Disease prevention strategies for QX disease (Marteilia sydneyi) of Sydney rock oysters (Saccostrea glomerata) Fri 30 Aug 2019 16:05:54 AEST ]]> Predicting the response of molluscs to the impact of ocean acidification Fri 21 Apr 2017 16:21:22 AEST ]]> The density and spatial arrangement of the invasive oyster Crassostrea gigas determines its impact on settlement of native oyster larvae Fri 11 Aug 2017 16:58:17 AEST ]]> Development of a method for identifying elevated vitellogenin gene expression in the Sydney Rock Oyster (Saccostrea glomerata) as an indicator of endocrine disruption on the Sunshine Coast Fri 08 Feb 2019 13:25:03 AEST ]]> The Impact of Ocean Acidification on Reproduction, Early Development and Settlement of Marine Organisms Fri 08 Apr 2016 08:49:25 AEST ]]> Uptake, distribution and depuration of paralytic shellfish toxins from Alexandrium minutum in Australian greenlip abalone, Haliotis laevigata Fri 07 Nov 2014 10:54:46 AEST ]]> Early ontogeny of the pipi, Donax (Plebidonax) deltoides (Donacidae; Bivalvia) Fri 07 Nov 2014 10:45:11 AEST ]]> Ontogenetic changes in salinity and temperature tolerance in the doughboy scallop, Mimachlamys asperrima Fri 03 Nov 2017 14:59:52 AEST ]]> Temporal patterns of reproductive condition in the doughboy scallop, Chlamys (Mimachlamys) asperrima Lamarck, in Jervis Bay, Australia Fri 03 Nov 2017 14:45:58 AEST ]]> Ontogenetic changes in optimal rearing temperatures for the commercial scallop, Pecten fumatus Reeve Fri 03 Nov 2017 14:31:57 AEST ]]>
