New and existing lipases will be applied to the concentration of omega-3 lipids from fish and algal oils. The primary aim of this project is to replace current chemical processes and high temperature distillation with milder enzymatic methods, providing high quality omega-3 concentrates for food and pharmaceutical purposes. The project aims to develop new immobilisation technology to enable multiple re-use of lipases for the cost effective production of omega-3 concentrates and to apply new microencapsulation strategies to the stabilisation of omega-3 concentrates, enabling the delivery of omega-3s and other bioactive ingredients to a range of food and beverage products.Read moreRead less
Removing the impediment to large-scale selective breeding of Australian barramundi: deciphering and manipulating the genetic basis of sex change. This project will determine the genetic basis of sex control in barramundi and develop technologies to allow barramundi hatcheries to have increased control over reproduction leading to more efficient propagation and removing impediments to selective breeding.
Striking Gold - Determining the genetics of gold skin colour in barramundi. Barramundi is one of Australia’s finest eating table fish and the species is gaining global prominence. However, fillet flesh colour of Australian farmed barramundi exhibit greyish tones which lowers consumer acceptance compared to other white flesh fish and imported product. Barramundi with rare golden skin tones do not exhibit this flesh "greyness" and are therefore a valuable niche product to farm if they can be produ ....Striking Gold - Determining the genetics of gold skin colour in barramundi. Barramundi is one of Australia’s finest eating table fish and the species is gaining global prominence. However, fillet flesh colour of Australian farmed barramundi exhibit greyish tones which lowers consumer acceptance compared to other white flesh fish and imported product. Barramundi with rare golden skin tones do not exhibit this flesh "greyness" and are therefore a valuable niche product to farm if they can be produced in larger numbers. This project will elucidate the genetic basis and mechanism of expression behind the golden barramundi phenotype. In doing so, it will enable barramundi farmers to produce them at commercially relevant scales, providing them with a substantial competitive advantage in both domestic and global markets.Read moreRead less
A pan-genome reverse vaccinology approach to disease prevention in farmed fish. Evolution of new pathogen strains causes major problems in vaccinated animals because these variants can reinfect and cause severe disease in previously protected animals. This project will use state-of-the-art genomics to find new targets that are essential to all strain variants, enabling development of broadly cross-protective vaccines for farmed animals.
Reducing skeletal malformations in cultured marine fish using gene expression, improved nutrition and advanced system operation. Reducing malformations in farmed fish will benefit the Australian economy and society by providing greater quantities of cheaper, higher quality fish. Increased farmed fish production, currently worth ~$300 million p.a., will increase exports and decrease imports (currently ~50% of all Australian consumed fish). To benefit are the important regional farming operations ....Reducing skeletal malformations in cultured marine fish using gene expression, improved nutrition and advanced system operation. Reducing malformations in farmed fish will benefit the Australian economy and society by providing greater quantities of cheaper, higher quality fish. Increased farmed fish production, currently worth ~$300 million p.a., will increase exports and decrease imports (currently ~50% of all Australian consumed fish). To benefit are the important regional farming operations in QLD, NSW, SA, NT, TAS and WA. In particular, the largest industry in Tasmania will profit by having a viable new species to farm (striped trumpeter) reducing risk due to climate change and global oversupply of salmon. Another important benefactor will be the rapidly expanding yellowtail kingfish industry. Read moreRead less
New hyphenated chromatographic and spectroscopic methods for oil analysis. This project aims to use novel chemical separation methods combined with spectroscopy to identify useful markers in olive oil and essential oil to ensure purity, quality and authenticity, which are all ongoing issues in these industries in Australia and overseas.

Development and evaulation of novel foods enriched with very long chain omega-3 fatty acids. This project is a collaborative effort between Meadow Lea Foods, Clover Corporation, and the Universities of Wollongong and Western Australia. The aims are 1) to develop a range of functional foods enriched with omega-3 from tuna oil; 2) to see whether the recommended omega-3 intake, currently nor met by most Australians, can be achieved by including these foods in the diet; 3) to evaluate sensory and he ....Development and evaulation of novel foods enriched with very long chain omega-3 fatty acids. This project is a collaborative effort between Meadow Lea Foods, Clover Corporation, and the Universities of Wollongong and Western Australia. The aims are 1) to develop a range of functional foods enriched with omega-3 from tuna oil; 2) to see whether the recommended omega-3 intake, currently nor met by most Australians, can be achieved by including these foods in the diet; 3) to evaluate sensory and health attributes and other factors that may impact on consumer acceptability hence market potential of the food range. There is little evidence of the feasibility let alone health and social benefits of utilising novel foods to meet the dietary omega-3 recommendation. We expect a) to show how consumers could benefit by using a range of such foods in their customary diet; b) to critically set this achievement within the context of current social trends in food product development.
