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
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

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.

The project aims to build knowledge to establish the world’s first sustainable onshore lobster aquaculture industry focused on commercial, sustainable and socially responsible lobster production from hatchery to market. The project will investigate novel systems engineering, specialised feed manufacture, determination and modification of seedstock quality, new frontiers in seedstock transport, all within an informed environmental and marketing framework. The project will provide alternate solutions for lobster culture in bio-secure and cost effective onshore systems. The outcomes are targeted at positioning Australia at the forefront of onshore lobster aquaculture, with opportunity for technology transfer to other aquaculture sectors.Read moreRead less
Trojan Y as a genetic solution for controlling and eradicating the Eastern mosquitofish, Gambusia holbrooki. The project aims to develop applied genetic strategies to eradicate Gambusia, a serious invasive pest fish species, from a Tasmanian estuary. The goal is to advance the Trojan Y chromosome model from theory to an applied solution. The project aims to employ an integrated ecological, physiological, behavioural, genetic and genomics approach, within the unique island-within-an-island status ....Trojan Y as a genetic solution for controlling and eradicating the Eastern mosquitofish, Gambusia holbrooki.
