Need

Knowledge of changing environmental conditions and productivity as a result of climate change is essential for adaptive management. In addition to direct applicability to fisheries and aquaculture in southern Tasmania, this information will have numerous important applications to other industries and stakeholders in the broader catchment.

CSIRO and TAFI have established a program (INFORMD- Inshore network for observation and regional management: Derwent-Huon) to guide multiple use coastal zone development and management. Storm Bay is an integral component of the INFORMD region and a priority is to understand both the short term (climate variability) and long-term (climate change) drivers of productivity in the region and link these to production of fisheries and aquaculture. CSIRO have a project investigating novel observing technologies (NOTe) to characterize the Derwent to shelf environment and TAFI will fund a charter vessel to monthly sample water column environmental variables, and support the CSIRO observing system. Thus an opportunity exists to obtain nutrient and productivity data in the Storm Bay region in a very cost-effective manner by collaborating with the existing research program.

Important background information is that the East Australian Current is predicted to penetrate further south causing significant warming and decreased productivity. Previous work (Harris et al 1991) showed that the nutrient status of waters clearly indicated the influence of the EAC, and primary producers indicated the productivity of the region, demonstrating the potential for Storm Bay to act as an indicator of productivity for Southern and Eastern Tasmania. Such information is important to understanding changes in fisheries and aquaculture production and, as a consequence, to assist with developing climate change adaptive management strategies.

This project also provides an opportunity for FRDC to invest in a project that will have significant influence on multiple use management in Australia.

Objectives

1. To provide information on the effects of a changing climate on water quality in Storm Bay and associated potential impacts on fisheries and aquaculture.
2. To collect nutrient and algal data from a targeted suite of sampling sites in Storm Bay to support sustainable development of the aquaculture industry.

Summary

This project has provided preliminary data on environmental conditions in Storm Bay that is assisting managers and marine industries to better understand effects of climate change and climate variability on fisheries and aquaculture in the region, including changing currents and primary productivity. This information is being used to inform the development of climate change adaptive management strategies for commercial and recreational fisheries and for the potential expansion of salmon aquaculture into Storm Bay. The environmental characterisation of Storm Bay is also supporting planning in the region, by providing baseline data and data for projects modelling the bay’s water circulation and ecosystem dynamics. This information will support the development of multiple use management plans for the region.

Need

Project funding will provide the PI with additional resources that enable him to focus on achieving the requirements and objectives of his research and PhD completion to a high standard and on-time.

The project funding application covers four key areas:

1. Additional stipend: to provide an adequate living allowance.
2. Travel: attendance of international conferences is a key vehicle to build skills an experience in the international policy and diplomacy fields as well as providing the opportunity to collect valuable research data. These skills and networks will ultimately benefit the Australian fishing and aquaculture community through the sharing of knowledge and networks.
3. Training: Facilitation training has been identified as an opportunity for development
4. Communication and content creation: developing content to assist with promoting and communicating the results of the research.

Having members and advocates of the Australian fishing and aquaculture community informed and skilled in the way international governance agreements are developed and then translated into domestic policy is extremely important, and a current gap in our capability and capacity.

Objectives

1. Research and describe the genesis of the High Level Panel for a Sustainable Ocean Economy as novel multilateral governance intervention.
2. Research and describe the operation, function and objectives of the High level Panel for a Sustainable Ocean Economy.
3. Critically analyse Australia's progress in meeting its commitments as a founding member of High Level Panel for a Sustainable Ocean Economy.
4. Successful completion and fulfilment of the requirements of the PhD.

Rebuilding Southern Rock Lobster stocks on the east coast of Tasmania: informing options for management

Understanding relationships between fisher behaviour, their expectations/aspirations, responses to changes in stock status and to management intervention is critical when implementing effective management strategies. This project aims to inform on the practical challenges to achieving the stock...

SCRC: SCRC RTG: Collaboration with Dr Salina Parveen to discuss comparisons of Vibrio parahaemolyticus models for Australian Pacific, Sydney Rock, and American Oysters at the University of Maryland (for Mark Tamplin)

Vibrio spp. are bacteria that naturally occur in oysters. Some Vibrio spp. such as V. parahaemolyticus cause human disease when levels are high and oysters are eaten raw. Predictive tools can be used to estimate V. parahaemolyticus levels in oysters, and to monitor and design cold chains that...

Rock Lobster Enhancement and Aquaculture Subprogram: preliminary investigation towards ongrowing puerulus to enhance rock lobster stocks while providing animals for commercial culture

Need

Development of a rock lobster aquaculture industry through the harvest of puerulus from the wild cannot proceed if there is a net loss of animals from the wild fishery. The concept of removing puerulus from the wild has received widespread opposition from participants in rock lobster fishing industries, and managers of the resource, as the resource is considered to be highly exploited. Rock lobster fisheries management policy in most states is specifically directed towards stock rebuilding and it is perceived that additional extraction by puerulus removal runs counter to those policies.

Current research on techniques for the extraction and on-growing of puerulus from the wild have proceeded with an assumption that puerulus extraction should be "biologically neutral". It has been proposed that "biological neutrality" can be achieved by a proportional reduction in catch of adult animals, either through a reduction in effort (eg removal of pots) or through buy-out of quota (in ITQ management). However, this mechanism for achieving biological neutrality has been criticised, as puerulus extraction is likely to occur in sheltered, heavily exploited regions - while the effort removed from the fishery may have been directed to a completely different region. In this scenario, puerulus extraction could lead to local depletion and loss of egg production, despite the concurrent reduction in effort.

The proposed project is directed to an alternative mechanism for compensating for the removal of puerulus. Reseeded animals can be released back to the same areas from which they were extracted so no localised depletion will result. Reseeding the area with animals additional to those required for biological neutrality will provide an enhancement benefit. This system has benefits to the fishing industry through enhanced yield, and also to the proposed aquaculture industry through access.

The potentially valuable on-growing industry is reliant upon the development of a mechanism for compensating for puerulus loss that does not harm the wild fishery.

Objectives

1. To develop methods to capture large numbers of 1 year old benthic juvenile rock lobsters, both for providing control animals and for monitoring survival of reseeded animals. (note that this is not puerulus collection)
2. To determine the extent of movement of reseeded and control juveniles after release, to assist in estimation of survival
3. To develop methods to assess relative survival of cultured juvenile lobsters released into a natural habitat.
