Lost at sea? Understanding adaptation and dispersal in spiny lobsters. Continual recruitment of young is fundamental to the replenishment of populations, especially when a stock is fished. Existing theory suggests that species with very long planktonic larval stages disperse widely, ensuring their genes are well mixed. However, recently identified genetic differences between populations of rock lobster challenge this paradigm and demonstrate that despite larvae mixing in the ocean for years, loc ....Lost at sea? Understanding adaptation and dispersal in spiny lobsters. Continual recruitment of young is fundamental to the replenishment of populations, especially when a stock is fished. Existing theory suggests that species with very long planktonic larval stages disperse widely, ensuring their genes are well mixed. However, recently identified genetic differences between populations of rock lobster challenge this paradigm and demonstrate that despite larvae mixing in the ocean for years, local recruitment and/or adaptation are at play. Recent developments in genomics and bioinformatics should allow this project to understand the ecological processes underpinning these genetic signatures and determine their evolutionary implications. Such findings could direct targeted rebuilding of depleted fisheries stocks.Read moreRead less
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

Summary
ARC Research Hub for Supercharging Tropical Aquaculture Through Genetic Solutions. 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 resist ....ARC Research Hub for Supercharging Tropical Aquaculture Through Genetic Solutions. 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
