Although Victoria has a well-established fishery independent monitoring program, in recent years the research focus has been toward improving the quality and quantity of fishery dependent data available. To properly realise this goal there is a strong and urgent need to make better use of industry (particularly the catching sector) as a vehicle for sampling and data acquisition.

To properly realise this goal there is a strong and urgent need to make better use of industry (particularly the catching sector) as a vehicle for sampling and data acquisition. Fishery independent monitoring is costly and limited by MAFRI resources, however it is well recognised that industry can potentially provide sampling opportunities that are at least an order of magnitude more numerous than those provided by fisheries agencies and research institutions. For instance, Victorian abalone divers each spend an average of about 50–55 days at sea each year to obtain the TAC. This equates to a total of at least 3,500 potential sampling opportunities. On many occasions divers visit more than one reef per day so that the number of opportunities is probably closer to about 5,000. The central issue is how to effectively utilise this industry potential for fishery assessment.
Scale fisheries have for many years had the benefit of scientific observers and fisheries extension officers, whereas such support for abalone fisheries is rare. Clearly this type of support will be needed before the Victorian abalone industry can be effectively engaged in sampling and data collection to support improved assessment of their fishery. In the absence of this support, industry based sampling becomes at best ad hoc and at worst ineffective and unsustained.
One of the areas where we have already demonstrated potential for industry to participate is in tagging abalone for growth studies. Growth in abalone characteristically exhibits high spatial heterogeneity to the extent that growth for one location has little meaning for other locations. Despite the release of about 35,000 tagged abalone across commercially important reefs, recapture rates have demonstrated that in most instances this quantity has been inadequate for obtaining sufficient growth data for fishery models to accommodate spatial heterogeneity in growth representatively. This presents particular challenges for modelling an abalone fishery at a geographical scale commensurate with the known population biology of this genus. The abalone industry offers one of the best opportunities for obtaining good growth data for a large number of locations, but experience has shown that effective participation of industry members requires support from scientifically trained persons.
Objectives: 1. Facilitate acquisition of data via industry including tagging for growth, size at maturity and length frequency of the catch. 2. Promote industry self-sufficiency in data collection including the training of deckhands and divers in sampling, measuring and recording techniques. 3. Develop appropriate management protocols to support on-going voluntary data collection by industry. Read moreRead less
Creating new methods to study structure vision. The majority of the structure within natural images is due to third to fifth order correlations between image points. Research has shown that sensitivity to this higher order structure, provides so called Structure Vision. Research has also shown that as few as three to four brain mechanisms are involved, and these may be related to the Minkowski functionals, which in turn are related to the structural and surface properties of real materials.

Research has also shown that as few as three to four brain mechanisms are involved, and these may be related to the Minkowski functionals, which in turn are related to the structural and surface properties of real materials. This project aims to build on recent discoveries of new stimuli to implement objective tests with which to study structure vision with the Partner Organisation. The project aims to also expand on realistic models of how Structure Vision may be computed by just a few coupled cortical pyramidal cells.Read moreRead less

Information processing in the brain. This project aims to understand the brain's functional organisation by developing non-invasive methods to characterise connectivity between interacting brain regions. No model-based methods to compute directional coupling between brain regions can be applied to large scale networks for resting state functional MRI data.

No model-based methods to compute directional coupling between brain regions can be applied to large scale networks for resting state functional MRI data. This capability would be a major breakthrough in neuroimaging, given uninformative (non-directional) network connectivity analysis restricts research. This project is expected to advance our understanding of information processing in the brain by providing a mechanistic approach to functional integration.Read moreRead less

Knowledge of adult fish movement and stock structure is fundamental to identifying the appropriate spatial scale at which the processes of population replenishment work, and thus the spatial units to which fishery management should be applied.

The management of the garfish fishery of South Australia has recently been at a heightened sensitivity due to serious concerns about the sustainability of the fishery. Yet, a comprehensive understanding of fundamental aspects of the life history and population biology of this species is lacking, which significantly impedes identifying the most appropriate spatial management structure. There is no understanding of the movement patterns of the adult fish, and the influence of that movement on the stock structure. Thus, it is not known the extent to which such movement helps sustain different regional populations and the extent to which these are independent and discrete. There is a need to rectify this lack of knowledge and understanding for southern sea garfish, so that management of the South Australian fishery can be applied at the appropriate spatial scale and spatial management units. Objectives: 1. To determine the spatial scale of movement of the adults of southern sea garfish (Hyporhamphus melanochir) in South Australia using a number of otolith-based techniques 2. and to utilise that information to determine the stock structure for this species.

We aim to investigate computer vision training data and test data, using automatically generated data sets for facial expression recognition and object re-identification. This project expects to quantify and understand the domain gap, the distribution difference between training and test data sets. Expected outcomes of this project are insights on measuring the domain gap, the ability to estimate model performance without accessing expensive test labels and improvements to system generalisation. This should provide significant benefits for computer vision applications that currently require expensive labelling, and commercial and economic benefits across sectors such as transportation, security and manufacturing.Read moreRead less
