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

This project will deliver the genetic knowledge to instigate world-leading and highly productive breeding programs for five tropical aquaculture species (barramundi, pearl oyster, prawn, grouper and marine algae) in northern Australia. It will integrate cutting edge genetic and genomic approaches into innovative aquaculture enterprises and will establish a novel understanding of the genetic basis of disease resistance and how the production environment interfaces with the bacterial microbiome, pathogens and water quality to cause disease. Outcomes will lead to increased productivity, international competitiveness, and lowered disease risk and significantly expand Australia's capacity in the aquaculture sector.Read moreRead less
Fighting disease on farms: how do vaccinations drive evolution of new pathogen strains? Vaccinating against some types of infectious diseases can drive evolution of new variants of the pathogen. This project will show how bacterial populations evolve in response to vaccination in farms, leading to new vaccination strategies and improved vaccine formulations to better control diseases that are caused by highly variable bacteria.
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.

Novel reproductive approaches to de-risk and transform barramundi breeding. Demand for Australian seafood outstrips supply. Farming of the iconic Australian barramundi is poised to play a major role addressing this shortfall; but innovative methods are needed to de-risk breeding processes and to provide precise control of maturation, spawning and genetic contribution of broodstock.

Demand for Australian seafood outstrips supply. Farming of the iconic Australian barramundi is poised to play a major role addressing this shortfall; but innovative methods are needed to de-risk breeding processes and to provide precise control of maturation, spawning and genetic contribution of broodstock. This project, in partnership with the world’s largest barramundi breeding company, will develop, test and apply novel breeding methods to obtain tight control over barramundi reproductive development and spawning. By combining cutting-edge genetic and applied breeding techniques, selective breeding programs will be more efficient and the genetic gains from breeding programs will be maximised.Read moreRead less
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

Enhance acceptance and ingestion of food pellets, thereby reducing leaching of nutrients vital to the fish and detrimental to the environment, 3. Help produce formulated diets that will offer the advantages of nutritional consistency, storage convenience, reduced feed waste and pollution and 4. Lower costs allowing for the successful and profitable production of barramundi and potentially other finfish. Read moreRead less
Triggering the dormant capacity of fish to make omega 3 fatty acids. Marine fisheries cannot expand further, leaving aquaculture (fish farming) with the challenge of meeting the growing demand for fish, whose consumption is known to enhance human health.

Marine fisheries cannot expand further, leaving aquaculture (fish farming) with the challenge of meeting the growing demand for fish, whose consumption is known to enhance human health. Fish oil is an essential component of the feed used in aquaculture, but there is a decreasing global supply of this commodity. This innovative nutritional biochemistry project boosts the capacity of fish to produce their own fish oil from vegetable oils in their diet. Therefore, this project will enable the expansion of aquaculture as an economically and environmentally sustainable means to produce the highest quality, nourishing fish for human consumption.Read moreRead less
Environmental and behavioural approaches for parasite resistant aquaculture. In modern fish aquaculture, parasite infections threaten efficient production. Ecological problems also arise when fish farms amplify parasite populations and cause outbreaks in surrounding wild fish populations. Present control methods rarely integrate the behaviour of the host fish. This project aims to assess the behaviours of hosts and the mechanisms that lead to parasite outbreaks. It will develop behavioural appro ....Environmental and behavioural approaches for parasite resistant aquaculture. In modern fish aquaculture, parasite infections threaten efficient production. Ecological problems also arise when fish farms amplify parasite populations and cause outbreaks in surrounding wild fish populations. Present control methods rarely integrate the behaviour of the host fish. This project aims to assess the behaviours of hosts and the mechanisms that lead to parasite outbreaks. It will develop behavioural approaches that separate host and parasite, reduce infection, and altering host behaviour to improve the effectiveness of treatments and minimise their environmental impacts. This project aims to create novel methods to control parasites in ways that limit their ability to evolve resistance.Read moreRead less
