Summary
Studies in school age children have shown that disruption to normal sleep patterns resulting from sleep disordered breathing (SDB) has severe consequences for both the cardiovascular system and neurocognition. To date there have been limited investigations of the effects of SDB in pre-school children despite the knowledge that disruptions to breathing during sleep are maximal at this age and the central nervous system which is immature and developing at this time, is most vulnerable to injury.

Summary
Disruptions to breathing during sleep (snoring), known as sleep disordered breathing occurs in up to 27% of children and forms a continuum of symptoms ranging from mild to severe. It has previously been thought that only severe disruptions to breathing, as occurs in obstructive sleep apnoea (OSA), were of clinical significance requiring intervention, however recent studies have shown that even snoring with no currently used signs of altered blood oxygenation levels or sleep disruption can have a ....Disruptions to breathing during sleep (snoring), known as sleep disordered breathing occurs in up to 27% of children and forms a continuum of symptoms ranging from mild to severe. It has previously been thought that only severe disruptions to breathing, as occurs in obstructive sleep apnoea (OSA), were of clinical significance requiring intervention, however recent studies have shown that even snoring with no currently used signs of altered blood oxygenation levels or sleep disruption can have a significant impact on daytime functioning and school performance. It is also known that cardiovascular disease is a long-term consequence of untreated sleep disordered breathing in adults, however the long-term effects on the cardiovascular system in children are unknown. This study will examine both the neurocognitive and cardiovascular effects of a range of severities of sleep disordered breathing in children and will identify new more sensitive markers of sleep disruption in order to predict neurocognitive dysfunction. In order to address this most important issue, this project will combine the expertise of scientists and clinicians in the fields of paediatric sleep, cardiovascular control and neuropsychological assessment from Monash and Melbourne Universities, and the Monash Medical Centre and Royal Children's Hospital.Read moreRead less

Towards An Industry-based Abalone Fishery Monitoring Program

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

Summary
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.

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.
