  • National Review of Ostrea Angasi Aquaculture: Historical Culture, Current Methods and Future Priorities
    National review of Ostrea angasi aquaculture: historical culture, current methods and future priorities Christine Crawford Institute of Marine and Antarctic Studies ! [email protected] " secure.utas.edu.au/profles/staff/imas/Christine-Crawford Executive summary Currently in Australia Ostrea angasi oysters (angasi) are being cultured on a small scale, with several farmers growing relatively small numbers of angasis on their predominately Sydney rock or Pacifc oyster farms. Very few farmers are culturing commercially viable quantities of angasi oysters. There are several reasons for this. Although angasi oysters occur in the intertidal zone, they are naturally most abundant in the subtidal and are less tolerant of fuctuating environmental conditions, especially temperature and salinity, than other oyster species. They also have a much shorter shelf life and start to gape after one to two days. Additionally, angasi oysters are susceptible to Bonamiosis, a parasitic disease which has caused major mortalities in several areas. Stress caused by extremes or a combination of factors such as high stocking densities, rough handling, poor food, high temperatures and low salinities have all been observed to increase the prevalence of Bonamiosis. Growth rates of angasi oysters have also been variable, ranging from two to four years to reach market size. From discussions with oyster famers, managers and researchers and from a review of the literature I suggest that the survival and growth of cultured angasi oysters could be signifcantly improved by altering some farm management practices. Firstly, growout techniques need to be specifcally developed for angasi oysters which maintain a low stress environment (not modifcations from other oysters).

  • Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
    Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.

In Europe, Ostrea edulis, the European flat oyster, and Ostreola stentina, the Provence oyster or dwarf oyster, are both present along the European and African, Atlantic and Mediterranean, coasts. In order to document the relationship not only between O. stentina and O. edulis, but also with the other Ostrea and Ostreola species, we performed a sequence analysis of the 16S mitochondrial fragment (16S rDNA: the large subunit rRNA-coding gene) and the COI fragment (COI: cytochrome oxidase subunit I).

  • Australian Flat Oyster (Ostrea Angasi) with Bonamia Parasites
    NAAHTWG Slide of the Quarter (January – March 2006) - Australian flat oyster (Ostrea angasi) with Bonamia parasites Cases submitted by Stephen Pyecroft and Judith Handlinger The Fish Health Unit, Mt Pleasant Laboratories, DPIWE, Tasmania Case 1 - 03/0658- 45: Cross section of an Australian flat oyster, Ostrea angasi. Case History The oyster from natural beds at St Helens, was collected during April for routine monitoring. This was part of a series of examinations, at approximately two-year intervals, of a population diagnosed with Bonamia infection approximately one decade previously. Over this period, the beds appeared to remain in good overall health, although some evidence of mortality was seen on several occasions and the extent of the beds was not fully assessed. This oyster was typical of three of 72 oysters examined, the others showing minimal pathology. Histopathology The overall condition is good, with plump Liedig cells indicating abundant glycogen stores, and a high columnar epithelium of most digestive gland tubules, indicating adequate recent feeding. Extensive multi-focal epithelial and sub-epithelial haemocyte infiltrates are present on the palps, main gut (especially stomach) and occasionally digestive gland tubules. Both granulocytes and more hyaline cells are present in the subepithelial reactions, though granulocytes are rarely discernible within the epithelia. In general, no pathogens can be seen in association with these lesions. Epithelial erosion is present in the stomach lesion (plus artefactual loss in some sections). Haemocytes and sloughed epithelial cells are present in the lumen of tubule with focal lesions, as well as in the surrounding interstitium, with necrotic tissue around some affected tubules.

  • Aquaculture in Western Australia
    Fact Sheet: Aquaculture in Western Australia Region North Coast, Gascoyne Coast, West Coast, South Coast Summary Despite Western Australia’s long coastline, our aquaculture industry is small by global standards – but it is growing and diversifying, with exciting opportunities on the horizon. Aside from contributing to food security, aquaculture creates employment and business opportunities in areas such as feed and equipment manufacturing. It also has direct and indirect economic benefits to the state, particularly in regional areas. In 2017-18, the total value of WA’s commercial fisheries and aquaculture production was $633 million. Of this, pearling (which is mostly commercially farmed) contributed $52 million (8%) and aquaculture $27 million (4%). Location of main aquaculture species farmed in Western Australia. Generated on 28/09/2021 https://marinewaters.fish.wa.gov.au/resource/fact-sheet-aquaculture-in-western-australia/ Page 1 of 8 Production for the Western Australian aquaculture industry in 2016/17 Current production – main aquaculture species in WA Barramundi Lates cacarifer Popular native table fish with high market demand which is sold as whole fish, live fish and fillets. WA’s barramundi production is largely located in the Kimberley region, at Cone Bay. Barramundi can be farmed in indoor recirculating systems, land-based ponds and sea cages. For more detailed information about barramundi aquaculture in Australia, see: https://www.agrifutures.com.au/farm-diversity/barramundi-aquaculture/ Barramundi farm in Cone Bay Rainbow trout Oncorhynchus mykiss Good eating fish that is popular with freshwater anglers. Trout was introduced to Australia for recreational fishing and aquaculture. It is difficult for the species to spawn naturally in WA’s conditions, so they are artificially bred in earthen and concrete ponds at the Pemberton Freshwater Research Centre.

Larvae were sampled with bongo nets and spat were harvested from collectors at monthly intervals. Abun- dances of predators Ž.Cymatium gastropods, and portunid, xanthid and majiid crabs were also recorded. A relationship between salinity, particulate organic matter and larvae abundance was observed, leading to peaks in abundance of spat on collectors some weeks later. Average catch rates of 10 spat collectory1 monthy1, using collectors made of cheap easily accessible materials, indicate that availability of P. imbricata is sufficient to initiate and support aquaculture of this species. Growth and mortality rates of juveniles in three different culture systems at two densities Ž.20% and 30%, i.e. percentage of available area covered by juveniles showed that density within the same culture system had no effect on growth, but that growth differed significantly among the three culture systems. Growth in ``bag'' systems was lower than in boxes whereas growth in ``suspended'' and ``bottom'' boxes was similar and comparable to the growth of a natural population.
