Understanding the stock-recruitment relationship to reverse the decline in the southern rock lobster. Declines in southern rock lobster fisheries across three Australian states show that we need to understand the flow and survival of larvae. The project aims to identify the fundamental links between recruitment and spawning stock, to enable predictions of recruitment for the management of adult stocks, safeguarding the future of the fishery.
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
Fishing for change: enhancing Australia’s seafood futures. Seafood production is an important part of Australia’s economy and future food security. In a dual relationship, fisheries are both vulnerable to and a cause of changes in the marine environment. This project will identify the maximum limits to Australian seafood production and will determine the impacts of future perturbations. To achieve this, the project will: combine existing rich historical data sources with state-of-the art ecosyst ....Fishing for change: enhancing Australia’s seafood futures. Seafood production is an important part of Australia’s economy and future food security. In a dual relationship, fisheries are both vulnerable to and a cause of changes in the marine environment. This project will identify the maximum limits to Australian seafood production and will determine the impacts of future perturbations. To achieve this, the project will: combine existing rich historical data sources with state-of-the art ecosystem and fisheries models; analyse environmental impacts that will complement national fisheries stock assessments that are essential for future competitive exports; and determine our growing seafood imports and their role in Australia’s and the world’s food security.Read moreRead less
Utilising innovative fishing technology to address key questions on the biology of Antarctic krill. Antarctic krill are an important species in the Southern Ocean supporting most of the Antarctic birds and mammals. A sustainable krill fishery is developing with krill products used in aquaculture and increasingly for human consumption. A new omega 3 krill oil industry has emerged and is rapidly expanding. The aim of the project is to predict the factors governing oil levels and the biochemical co ....Utilising innovative fishing technology to address key questions on the biology of Antarctic krill. Antarctic krill are an important species in the Southern Ocean supporting most of the Antarctic birds and mammals. A sustainable krill fishery is developing with krill products used in aquaculture and increasingly for human consumption. A new omega 3 krill oil industry has emerged and is rapidly expanding. The aim of the project is to predict the factors governing oil levels and the biochemical composition in krill which will help us understand growth, reproduction and recruitment. The research aims to also assess the possible effects of climate change on krill. Outcomes of this research aim to be used to manage the expanding krill fishery.Read moreRead less
