The link between environmental stress and disease onset in prawn aquaculture. The federal government has set a target for prawn aquaculture production to increase fourfold by 2010. A major barrier is disease: losses of 20% of production to viral diseases are not uncommon. To be internationally competitive, Australia needs to develop high health production systems. Most prawn stock carry chronic viral infections, but only exhibit disease symptoms following environmental stress. This project will ....The link between environmental stress and disease onset in prawn aquaculture. The federal government has set a target for prawn aquaculture production to increase fourfold by 2010. A major barrier is disease: losses of 20% of production to viral diseases are not uncommon. To be internationally competitive, Australia needs to develop high health production systems. Most prawn stock carry chronic viral infections, but only exhibit disease symptoms following environmental stress. This project will identify environmental stressors that activate viral disease in Penaeus monodon. Outcomes will be incorporated into on-farm managerial regimes to minimize risk of crop loss to disease. Development of biomarkers as indicators of stress related risks may be commercialized.Read moreRead less
Aquaculture of the tropical abalone: identifying and selecting for factors promoting high settlement, survival and growth. There is a growing demand worldwide for the 'cocktail'-sized tropical abalone Haliotis asinina. We have developed a full set of hatchery and grow-out procedures that Queensland Sea Scallops Pty Ltd will test on a commercial scale. At QSS, we will propagate and growout Haliotis asinina to determine the factors controlling settlement, survival, growth and health. We will do ....Aquaculture of the tropical abalone: identifying and selecting for factors promoting high settlement, survival and growth. There is a growing demand worldwide for the 'cocktail'-sized tropical abalone Haliotis asinina. We have developed a full set of hatchery and grow-out procedures that Queensland Sea Scallops Pty Ltd will test on a commercial scale. At QSS, we will propagate and growout Haliotis asinina to determine the factors controlling settlement, survival, growth and health. We will do this by combining breeding experiments with microarray gene profiling and other advanced gene expression studies. This knowledge will enhance the development of this new aquaculture industry in tropical Australia and our understanding of abalone aquaculture in general.Read moreRead less
Combinatorial controlled gene expression delivering crops resistant to nematodes. Root-knot nematodes cause US$130 billion crop losses worldwide pa, and at least AUS$ 450 pa in Australia. Current control methods involve fumigation, chemicals (mainly carbamates and organophosphates), natural plant resistance and biological control. The fumigants (eg methyl bromide) are being phased out because they damage the ozone layer, most of the non-fumigants are being banned because of environmental damag ....Combinatorial controlled gene expression delivering crops resistant to nematodes. Root-knot nematodes cause US$130 billion crop losses worldwide pa, and at least AUS$ 450 pa in Australia. Current control methods involve fumigation, chemicals (mainly carbamates and organophosphates), natural plant resistance and biological control. The fumigants (eg methyl bromide) are being phased out because they damage the ozone layer, most of the non-fumigants are being banned because of environmental damage and persistence in groundwater, and biological control has had limited success. These problems are addressed in this project with development of synthetic plant resistance to nematodes, which will benefit horticultural and broadacre farming by reducing pathogen losses and improving quality.Read moreRead less
Translating genomic discoveries into improved commercial outcomes for the South Sea pearl industry. The purpose of this project is to understand the relationship between gene expression and pearl quality. By identifying the relationship between genes and pearls this project will determine the best conditions to grow selected pearl oyster stocks for the Australian South Sea pearl industry.
