The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neuro ....The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neurohomones that control both appetite and physiological stress in fish have in stimulating the resumption of feeding after sea water transfer.The basic knowledge generated will be used directly in development of strategies for minimising smolt failure in Atlantic salmon aquaculture.Read moreRead less

Summary
Commercial development of rock lobster culture systems: the cutting edge of aquaculture. Commercial development of rock lobster culture systems: the cutting edge of aquaculture. This Research Hub will develop unique aquaculture systems, using novel engineering manufacture to mass produce lobster seed stock. A reliable, large-scale supply of seed will enable seacage culture, evaluation of wild stock enhancement and lead to sustainable food production.
ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ....ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less
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
Redefining the molecular mechanism underlying crustacean metamorphosis. This project uses the astonishing lifecycle of lobster larvae to better define the pathways and discover the key genes that regulate crustacean metamorphosis. Where, when, why and how metamorphosis occurs in crustaceans are important factors affecting fisheries recruitment and aquaculture production. The project suggests that the current accepted paradigm for the molecular control of metamorphosis does not apply to lobsters ....Redefining the molecular mechanism underlying crustacean metamorphosis. This project uses the astonishing lifecycle of lobster larvae to better define the pathways and discover the key genes that regulate crustacean metamorphosis. Where, when, why and how metamorphosis occurs in crustaceans are important factors affecting fisheries recruitment and aquaculture production. The project suggests that the current accepted paradigm for the molecular control of metamorphosis does not apply to lobsters and possibly other crustaceans where larval metamorphosis and the juvenile transformation are uncoupled. Using a unique supply of cultured lobsters and advanced molecular techniques, the project aims to develop tools to trigger and synchronise metamorphosis for use in aquaculture and invasive species management.Read moreRead less
