PAST PROJECTS

2015/706

OveRCOMING TECHNICAL CONSTRAINTS TO SYDNEY ROCK OYSTER HATCHERY PRODUCTION

While large batches of several million SROs have been produced in hatcheries in NSW, the techniques have not been sufficiently reliable to be adopted commercially to make these specially selected oysters available to industry. Two distinct problems have plagued hatchery production. 1) Larval anorexia or starvation has affected many hatchery production runs and occurs when the oysters are between 2 to 8 days old. 2) Spat mortality occurs later when the oysters are approximately 1 – 1.5 months old and are being held in nursery systems outside the hatchery.  To overcome this high mortality of young oysters, several complementary strategies have been developed.

2014/721

This project resulted in the genetic analysis to allow Australian Seafood Industries (ASI) to formulate a breeding plan for the 2014 breeding season. In addition the data analysis resulted in the prioritisation of traits by industry stakeholders resulting in an agreed focus for breeding. The process resulted in training opportunities in the form of a workshop for Pacific Oyster and other industry participants to examine the requirements for managing a modern family based breeding program.

2014/243 (FIS)

NSW Oyster Industry Strategic Development Plan

This project aims to create a NSW oyster industry strategic development plan.

2013/709

This project was developed to progress the long term commitment of both industry and research providers to providing lines of Sydney Rock Oyster selected for growth rate, shell shape and disease resistance, to farmers of this species. It progresses commercialisation outcomes and provides a platform for the delivery of outcomes of past and current CRC research projects. 

2013/708

Safe spat rearing experiment

The objective of this study was to obtain information about simple and practical methods to treat/disinfect water so as to develop a method for hatcheries to safely produce and rear spat in infected estuaries. 

2013/701

9th International Conference on Molluscan Shellfish Safety, Sydney, March 2013

The Seafood CRC sponsored a session at the 9th International Conference on Molluscan Shellfish Safety to promote the leading work being undertaken by the Seafood CRC. 

2012/760

This project aimed to improve the understanding of Pacific Oyster Mortality Syndrome (POMS) and the genetic inheritance of POMS resistance. This knowledge can then be used to recommend a breeding strategy that includes resistance to POMS. 

2012/740

EVALUATING THE IMPACT OF AN IMPROVED RETAILING CONCEPT FOR OYSTERS IN FISHMONGERS

This project aimed to:

  1. Increase the sales of fresh oysters in six trial fishmongers via improved merchandising (retail presentation and in-store theatre) and information at point of sale

  2. Determine the value proposition, including benefit cost considerations related to expansion of the concepts to more fish mongers.

2012/713

Understanding conditioning of Sydney Rock Oysters

This project set out to identify Sydney Rock Oyster neuropeptides that affect reproduction in order to develop technologies for improving reproductive condition and spawning. 

2011/772

Impacts and predictive modelling of coastal upwelling on the South Australian oyster industry

This project compiled and studied data that has been collected over the past 10 years within oyster harvesting areas. This information was used to understand how the presence of phytoplankton (or lack thereof) varied with weather conditions or mortality events. This will then inform growers of best farming times, provide a predictive ability to put product in the water and give some certainty as to mortality events. 

2011/766

Seafood CRC Oyster Business Benchmarking Project Report on Extension Activities

This project was completed by RDS Partners under contract by the Australian Seafood CRC to assist with gathering and collating feedback from the oyster industry regarding extension and promotion activities associated with the “Benchmarking the Australian Oyster Industry Project”. 

2011/726

Wanted dead or alive: novel technologies for measuring infectious norovirus particles

This project aimed to develop sensor surface functionality of novel detection technology to improve discrimination between infectious and non-infectious norovirus in oyster. 

2011/718

Molecular analysis of the effect of stressors on oysters

During their life-time, cultivated and wild oysters are exposed to a variety of environmental stressors, including salinity and temperature fluctuations, pollution and pathogens in their natural habitat. This study generated and examined the changes in transcriptome of Sydney Rock Oysters in response to environmental stressors. 

2010/734

Oyster over-catch: Cold shock treatment

A commercial scale, hypersaline, cold-shock bath, dubbed the “Super Salty Slush Puppy” was constructed to provide proof of concept of cold shock treatment for over-catch control. 

2010/724

Development of tools for the sustainable management of genetics in polyploid Pacific Oysters

This thesis developed and utilised suites of microsatellite markers to determine the baseline diversity of native, naturalised and cultured diploid oysters.
