Population structure in the giant Australian cuttlefish - implications for management of a unique eco-tourism and fishery resource in regional Australia. A management strategy for the giant Australian cuttlefish in regional South Australia is required urgently because of potential conflict between ecotourism and fishery sectors. At present, development of a management strategy is stymied by lack of information on stock structure and movements. Analyses of variation in gene frequencies, morphom ....Population structure in the giant Australian cuttlefish - implications for management of a unique eco-tourism and fishery resource in regional Australia. A management strategy for the giant Australian cuttlefish in regional South Australia is required urgently because of potential conflict between ecotourism and fishery sectors. At present, development of a management strategy is stymied by lack of information on stock structure and movements. Analyses of variation in gene frequencies, morphometric and chemical trace element profiles in calcified structures among locations and years will enable the geographic extent of populations or stocks to be determined, including whether natal homing occurs. Such information is critical to sustainable management of the species and design of a marine protected area in the upper Spencer Gulf.Read moreRead less
Assessing the benefits of closed fishing areas for spawning aggregations and egg production for coral trout. Coral trout is a valuable finfish species that inhabits coral reef systems in Australia. Like most other finfish species, coral trout is managed mainly through catch and size limits. However, closed fishing areas also provide a degree of protection from exploitation. Worldwide, closed fishing areas have been shown to provide larger and more fish within their boundaries. At present, there ....Assessing the benefits of closed fishing areas for spawning aggregations and egg production for coral trout. Coral trout is a valuable finfish species that inhabits coral reef systems in Australia. Like most other finfish species, coral trout is managed mainly through catch and size limits. However, closed fishing areas also provide a degree of protection from exploitation. Worldwide, closed fishing areas have been shown to provide larger and more fish within their boundaries. At present, there are limited empirical data to show that they provide benefits to fish stocks. This project aims to examine whether closed fishing areas provide a benefit to coral trout at the Abrolhos Islands, Western Australia.Read moreRead less
How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I prop ....How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I propose to compare the life histories and microchemical signatures in larval otoliths of endemic and closely related non-endemic reef fishes to determine the mechanisms and prevalence of self-recruitment. The results will broaden our understanding of how marine populations are replenished, information critically needed for marine conservation and resource management.Read moreRead less
Ontogeny of Behaviour and Sensory Abilities in Larvae of Marine Fishes. This project examines development of swimming performance, other behaviours and sensory abilities relevant to dispersal in larvae of a variety of marine fish species. Both laboratory and field methods will provide an overview of larval behaviour and sensory abilities throughout ontogeny. The extent to which morphological development explains these developmental differences in behaviour and sensory ability will be examined ....Ontogeny of Behaviour and Sensory Abilities in Larvae of Marine Fishes. This project examines development of swimming performance, other behaviours and sensory abilities relevant to dispersal in larvae of a variety of marine fish species. Both laboratory and field methods will provide an overview of larval behaviour and sensory abilities throughout ontogeny. The extent to which morphological development explains these developmental differences in behaviour and sensory ability will be examined in reared and wild individuals. This will provide direct evidence of when during the larval phase that fishes are able to actively modify dispersal patterns. This is important information for management of marine living resources and design of marine reserves.Read moreRead less
Enhancing coral reef resilience to climate change. Coral reefs provide enormous economic, cultural and environmental benefits to Australia and its near neighbours. For reefs to remain healthy in the face of climate change and other stresses, they must be managed using best practices. Measuring how reef populations are connected and developing new tools to translate this knowledge into improved management can enhance fisheries, ensure reef health, and protect the livelihoods that reefs sustain.

For reefs to remain healthy in the face of climate change and other stresses, they must be managed using best practices. Measuring how reef populations are connected and developing new tools to translate this knowledge into improved management can enhance fisheries, ensure reef health, and protect the livelihoods that reefs sustain. This research with partners from Europe, the United States of America, Papua New Guinea and Indonesia places Australia at the forefront of addressing the impacts of climate change and enhances its international reputation as the world leader in coral reef science and management.Read moreRead less
