Economic analyses of Australia's Sydney rock oyster industry
2015
This thesis provides the first comprehensive assessment of the economic viability of Australia's Sydney rock oyster industry and forms the bases for future policy and industry management recommendations. In the four separate studies of the thesis, the socio-economic profile of the industry, the market price formation dynamics within Australia's oyster market, efficiency and productivity levels and the potential impact of climate change and market dynamics on the industry's future revenue were investigated. Findings of this project suggest, for example, that market dynamics may pose a greater thread to the future development of this industry than direct effect from climate change.
History, status and future of Australia’s native Sydney rock oyster industry
Aquatic Living Resources, 2014
The Sydney rock oyster (Saccostrea glomerata) (SRO) is an oyster species that only occurs in estuaries along Australia's east coast. The SRO industry evolved from commercial gathering of oyster in the 1790s to a high production volume aquaculture industry in the 1970s. However, since the late 1970s the SRO industry has experienced a significant and continuous decline in production quantities and the industry's future commercial viably appears to be uncertain. The aim of this study was to review the history and the status of the SRO industry and to discuss the potential future prospects of this industry. This study summarised findings of the existing literature about the industry and defined development stages of the industry. Particular focus was put on the more recent development within the industry (1980s-present) which has not been covered adequately in the existing literature. The finding from this study revealed that major issues of the industry are linked to the management of prevailing diseases, the handling of water quality impairments from increasing coastal development, increasing competition from Australia's Pacific oyster (Crassostrea gigas) industry and the current socioeconomic profile of the industry. The study also found that policy makers are currently confronted by the dilemma of saving a "dying art". Findings from this industry review may be vital for current and future fisheries managers and stakeholders as a basis for reviewing industry management and development strategies. This review may also be of interest for other aquaculture industries and fisheries who are dealing with similar challenges as the SRO industry.

The access regulation within the shellfish farming sector in France is based on a co-management system relying on both a national legislation, defining the general access conditions to maritime public grounds, and regional regulation systems, called "Regional Structural Schemes". The latter specify the farming rules in cooperation with the administration, scientific and professional representatives. This regulation system, which aims at managing the common primary resources at the scale of a shellfish farming basin, is under review in the baie des Veys, on the Normandy coastline. In this context, biological modelling is used to assess the carrying capacity of the bay and to provide tools for modifying the RSS in a more sustainable way. Another objective of the study is to shift to bio-economic modelling, implying for the model to take into account extra technical and economical parameters. A specific survey has therefore been carried out for collecting detailed information on the cultural practices of the oyster farming companies, and for analysing the links with their structural characteristics and performance indicators, in terms of productivity and output. This article reviews the context of oyster farming in the baie des Veys from the environmental, socioeconomic and institutional point of view. After the presentation of the methodology used for the survey, its results are analysed and a synthesis is made, leading to the identification of the main farming technical profiles. At this stage of the study, only theoretical developments on modelling are considered and outlooks in terms of collective management measures are discussed.
The Changing Face of Oyster Culture in New South Wales, Australia
Journal of Shellfish Research, 2009
Oyster farming is one of the oldest aquaculture industries in Australia and, in New South Wales (NSW), its history dates back some 130 y. Like other industries, it has evolved over time, but during the past 5 y, a number of significant changes have occurred. Although Sydney rock oysters (Saccostrea glomerata [SRO]) remain the most important commercial species, the culture of Pacific oysters (Crassostrea gigas), particularly triploids, has increased significantly. Interest in cultivating other commercially important species, such as flat oysters, Ostrea angasi, has also increased. Overall, hatchery-produced oyster seed has become more readily accessible, particularly for S. glomerata, which, prior to 2003, had been largely unavailable to the majority of the rock oyster industry. For both S. glomerata and C. gigas, breeding programs have become an integral part of industry development and have been the primary reason for hatchery seed uptake in NSW. Across the oyster industry, the emphasis placed on the importance of demonstrating environmental sustainability has increased, and both industry and government have been proactive in protecting the estuarine environments in which oyster farming occurs. Collectively, hatchery development, oyster breeding, and environmental research has ''spawned'' a number of new research initiatives that have increased fundamental oyster research during the past 5 y.
Aquaculture Economics & Management, 2014
Economic competition between introduced and native aquaculture species is of interest for industry stakeholders since increased production can affect price formation if both aquaculture species are part of the same market or even substitutes. In this study, we focus the Australian edible oyster industry which is dominated by two major speciesthe native Sydney rock oyster (grown mainly in Queensland and New South Wales) and the non-native Pacific oyster (grown mainly in South Australia and Tasmania). We examine the integration of the Australian oyster market to determine if there exists a single or several markets. Short and long run own, cross price and income flexibilities of demand are estimated for both species using an inverse demand system of equations. The results suggest that the markets for the two species are integrated. We found evidence that the development of the Pacific oyster industry has had an adverse impact on Sydney rock oyster prices. However, our results show that both species are not perfect substitutes. Demand for Sydney rock oysters is relatively inelastic in the long run, while no long run relationships can be identified for Pacific oysters, reflecting the developing nature of this sector.
