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
Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish gr ....Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.Read moreRead less
Developing solutions to marine mammal interactions with long-line fisheries. Developing solutions to marine mammal interactions with long-line fisheries. This project aims to use innovative techniques to determine aspects of natural marine mammal behaviour that can be exploited, in conjunction with optimal fishing vessel operations, to minimise their interactions with commercial fisheries. Marine mammal interactions with commercial fisheries are a growing worldwide issue with both ecological (in ....Developing solutions to marine mammal interactions with long-line fisheries. Developing solutions to marine mammal interactions with long-line fisheries. This project aims to use innovative techniques to determine aspects of natural marine mammal behaviour that can be exploited, in conjunction with optimal fishing vessel operations, to minimise their interactions with commercial fisheries. Marine mammal interactions with commercial fisheries are a growing worldwide issue with both ecological (incidental bycatch and increased dependence on fisheries) and economic consequences (annual losses of tens of millions of dollars to the fishing industry). Successful solutions to reduce these interactions have remained elusive. Outcomes from this research are expected to be applicable worldwide, have substantial economic and ecological benefits, and ensure the sustainability of the fishing industry.Read moreRead less
A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit i ....A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit in areas where a strong need exists for conservation of prey species with economic importance too low to justify expensive at-sea research.Read moreRead less
