Feasibility of Shellfish Reef Restoration in a South-Western Australian Estuary Feasibility of shellfish reef restoration in a south-western Australian estuary This thesis is presented for the degree of Bachelor of Science Honours, College of Science, Health, Engineering and Education, of Murdoch University, 2019 Lauren Peck (BSc) Declaration I declare that this thesis is my own account of my research and contains as its main content work which has not previously been submitted for a degree at any tertiary education institution. Lauren Peck Abstract With 85% of oyster reefs lost around the world within the last 130 years, these reefs are now one of the most threatened marine habitats in the world and in Australia less than 10% of naturally occurring oyster reefs remain. Shellfish reefs provide a range of services that promote healthy ecosystems, including water filtration, fish production and shoreline erosion. In estuaries, these services are extremely important as human activities are increasing degrading these environments. Thus, shellfish reefs can aid in restoring ecosystem functioning of an estuary while providing additional ecosystem services. The aim of this study was to determine the feasibility of a number of shellfish reef options for the Peel-Harvey Estuary in south-western Australia. This first involved exploring the historical and current distributions of shellfish to elucidate whether shellfish reefs existed in the Peel-Harvey Estuary and to identify a suite of candidate species. A bioclimatic modelling approach was then used to elucidate the suitability of five native Australian oyster species to the environmental conditions that occur in the Peel-Harvey Estuary, the largest estuary in south-western Australia. Laboratory tank trials were then used to validate the results of that model, in which the two most suitable species, i.e. Ostrea angasi and Saccostrea glomerata, were exposed, for two months, to the extremes in water temperature and salinity that occur in the Peel-Harvey Estuary during summer (26◦C and 48ppt) and winter (15◦C and 14ppt) and their survival, body condition index (BCI) and behaviour (valve activity) monitored. The probability of survival (S) over the duration of the study was lowest for O. angasi in the summer (S=0.0) and winter treatments (S=0.18), which both differed significantly (P<0.001) from the control group (marine condition), and were consistent with the salinity in the winter and summer treatments falling outside previously recorded tolerance thresholds. In contrast, S. glomerata had a high probability of survival in winter (S=0.98), and ~50% survived the extreme summer conditions. A significant difference of valve activity was found for O. angasi between the three conditions (P<0.05), however, only a iii significant difference in valve activity for S. glomerata was found between the marine and summer (P<0.05), and marine and winter conditions (P<0.05). Overall, body condition index (BCI) did not differ significantly (P>0.05) before or among treatments. The results of the bioclimatic model and survival analyses suggest that S. glomerata was the most suitable candidate for shellfish reef restoration in the Peel-Harvey Estuary, given in particular the extremes that occur in salinity. Further work is required to determine the most suitable areas in the estuary that would maximise survival and growth and thus where such reefs would have a positive impact on the overall health and resilience of the Peel-Harvey Estuary. iv Contents Abstract ..............................................................................................................................iii Acknowledgements ........................................................................................................... vi Chapter 1: General introduction .......................................................................................... 1 1.1 Importance of oyster reefs ......................................................................................... 1 1.2 Threats to oyster reefs .............................................................................................. 2 1.3 Monitoring stress in oysters ....................................................................................... 6 1.4 Oyster reef restoration .............................................................................................. 7 1.5 Australian reef-forming oyster species ...................................................................... 8 1.5.1 Potential for filter feeders to ameliorate degradation of south-western Australian estuaries ................................................................................................................... 11 1.6 Aims ....................................................................................................................... 12 Chapter 2: Materials and Methods .................................................................................... 13 2.1.

This would not have been possible without Alan helping to set up the tank system, and always being there to help when something goes wrong. Thank you both for always providing feedback on my drafts, guidance through analyses, and for developing my writing and research skills. Thank you to the Blue Lagoon Mussel Farm and the Albany Shellfish Hatchery for the generous donation of oysters, which without, this project could not have been possible. To the Harry Butler Institute, thank you for the scholarship award, this has provided me freedom to be able to solely focus on my thesis and not stress about finances. Lastly, thank you to my family, my partner, Joe, and close friends, for the continuous support throughout the last 18 months. To my parents, this would not have been possible without your on-going support, love and faith. I wouldn’t be where I am today, without you all. vi Chapter 1: General introduction 1.1 Importance of oyster reefs Oyster reefs are distributed in intertidal and subtidal waters throughout a range of aquatic habitats, from freshwater to coastal environments (Guo et al., 2015). These habitats can occur in a range of physiochemical conditions, from the relatively stable marine environment to the fluctuating estuarine environment (Akberali & Trueman, 1985). In estuaries, water temperature and salinity are major limiting factors that determine shellfish distribution (Heilmayer et al., 2008; Munroe et al., 2013; Lowe et al., 2017). Oysters are not capable of regulating their body temperature or salinity of their body fluids, as a result, their metabolic activity and salt content is influenced by their surrounding environment. The synergistic effect of temperature and salinity affects virtually every aspect of an oyster’s life, influencing their physical extent and physiological rates, which controls their survival,

    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).

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.

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.
