Where many commercial fisheries have regular collection and estimation process for economic data, this is not the case for recreational fishing in most of Australia. This lack of data also includes behaviour and motivations and how they are changing. These data are useful for informing discussions on resource allocation and in understanding and managing recreational fisheries more generally. If these data are to be used to inform governments and the general public, there is a need to make sure it is collected in a robust way that is representative of the Australian population. Large scale representative data sets are often expensive to acquire and as a result do not get undertaken regularly. One off surveys only provide useful data for any particular point in time, but understanding trends can often be more useful. This study aims to implement and test methodologies to provide a robust and representative sample, while trying to reduce costs to allow for more regular data gathering. To do this requires addressing another need: that of testing new survey methodologies for collecting data from recreational fishers that enables assessment of social and economic contribution. Recreational fishing surveys traditionally use probability based phone or mail surveys, however both methods are experiencing rapid decline in response rates and representativeness. It is expected that going into the future, online surveys that use a range of appropriate recruitment methods will be the most common survey method. There is a need to invest in establishing robust approaches to using these methods, and in understanding how their findings differ to those of traditional probability based surveys. Objectives: 1. Assess social and economic contribution of recreational fishing using multiple methods, including direct and flow-on economic benefits, and market and non-market benefits 2. Identify which approaches to recruiting survey participants and completing surveys produce the most representative and robust results 3. Recommend most appropriate and cost effective survey method to use to track change social and economic aspects of recreational fishing in Australia over time Read moreRead less

Summary
The primary need of this project is to facilitate a profitable Longspined Sea Urchin fishery to move the industry away from subsidies. A large-scale sustainable fishery is seen as the most feasible and sustainable way to apply downward pressure on the rapidly expanding Sea Urchin population in Tasmania. Longspined Sea Urchin populations have grown to some 20 million (5,500 tonnes) and have resulted in 15% of the Tasmania East Coast reefs becoming unproductive urchin barren, up from 3% 15 years ....The primary need of this project is to facilitate a profitable Longspined Sea Urchin fishery to move the industry away from subsidies. A large-scale sustainable fishery is seen as the most feasible and sustainable way to apply downward pressure on the rapidly expanding Sea Urchin population in Tasmania. Longspined Sea Urchin populations have grown to some 20 million (5,500 tonnes) and have resulted in 15% of the Tasmania East Coast reefs becoming unproductive urchin barren, up from 3% 15 years ago.
Subsides for the Longspined Sea Urchin harvest commenced in 2016 and in the last 3 years some $500,000 has been spent. This initiated significant investment in the industry to facilitate export market establishment and resulted the 2019 harvest reaching an excess of 550 tonnes, now Tasmania’s 3rd largest wild fishery by weight. However, the industry needs to move away from subsides and waste utilisation is seen a viable option to turn a current financial cost (estimated at $80,000 in 2019 to dump 400 tonnes of waste generated) into an income stream.
FRDC 2016-208 highlighted the significant potential of sea urchin waste utilisation in the agricultural industry and called for commercial upscaling of trials. This project is designed to meet that need. Based on this, the Abalone Industry Reinvestment Fund (AIRF) has committed to providing $538,686 in kind to initiate the project. This whole of project application is to allow multi-season agricultural trials of waste products to obtain scientifically and industry meaningful results, allow testing on perennial crops (such as cherries) and to employ a dedicated post-doctoral researcher on the project.
In the push for sustainably produced food, agricultural industries are demanding alternative nutritional sources to synthetic fertilisers. Urchin waste is comprised of two major parts: gut waste - a nitrogenous rich liquid which can be converted in a stable drench or spray and; shell waste – a calcium and boron rich solid which can be dried and powdered for use as a soil ameliorant. As such this fisheries enhancement project will additionally for fill this agricultural need.
Objectives: 1. To develop commercial scale processing equipment of sea urchin waste. 2. Determine the nutrient composition and plant bioavailability of nutrients from two high throughput waste streams: liquid gut waste and dried powdered shell waste 3. Evaluate the agronomic benefits of liquid gut waste as a frost retardant in perennial tree cropping (cherries) 4. Evaluate the agronomic benefits of powdered shell waste as a soil ameliorant in a wide range of annual and perennial cropping systems 5. Undertake a cost benefit analysis comparing fertiliser products (foliar sprays and/or soil conditioners) from this work to other products on the market to assess if the products are commercially viable Read moreRead less

Recreational fishing estimates are critical to ensure sustainable harvest of community owned fisheries resources. In South Australia, established Fishery Management Plans are in place and recreational catch must be monitored to ensure that the sector is operating within its allocated shares of the resource. Recent changes to the availability of traditional sampling frames and shifts in the way the people communicate mean that it is becoming increasingly cost-prohibitive to undertake surveys using the established methodology. There is a need to re-evaluate how recreational fishing catch and effort is assessed and to develop revised survey methodologies using the latest survey tools and techniques.
Smartphone applications may provide a cost-effective method to collect information on recreational catch. However, as most apps are self-selected, sampling is non-probability based and it is not possible to calculate confidence intervals or margins of error. There is a need to compare app-based data with traditional phone-diary surveys to compare estimates and evaluate the accuracy of the results measured relative to independent population benchmarks. The outputs from this project will provide valuable information to other jurisdictions who have existing apps or are looking to implement an app.- based survey
Objectives: 1. To design and implement a survey of South Australian recreational fishers to determine participation and catch and effort levels for key species. 2. To evaluate the differences and in recreational catch estimates from smart-phone applications and traditional phone diary surveys. 3. To explore whether smart-phone applications can be feasibility integrated into future recreational fishing surveys. 4. To measure the accuracy of catch estimates from smart-phone applications relative to independent population benchmarks. 5. To outline the policy and regulatory needs and implications of implementing a smart phone based reporting app. Read moreRead less

One of the key objectives of ESD is "to protect biological diversity and maintain essential ecological processes and life-support systems". Addressing the ecological impacts of an overabundant legacy population of Silver Gulls in close proximity to tuna operations in Port Lincoln has been identified as a priority by ASBTIA, in consultation with DEW and PIRSA, to address this ESD objective.
The project is a collaboration between resource management agencies and the tuna aquaculture industry in Port Lincoln. It seeks to expand on the research of Harrison (2010) to assess a three-year trial of Silver Gull egg oiling on selected off-shore islands near Port Lincoln and its impact on local reproductive success and population numbers of Silver Gulls. In doing so it aims to assess the efficacy of egg oiling as a possible management technique to control growth of Silver Gull populations and thereby reduce the current detrimental economic, social and environmental impacts associated with recent increases in Silver Gull numbers in the Port Lincoln region.
Information provided through the research project will inform any ongoing monitoring and management of over-abundant Silver Gull populations within the frameworks of the region's National Park Management Plans and within PIRSA Aquaculture policy objectives. The efficacy of egg oiling and indices measured in the project will also be assessed to provide guidance on any future egg oiling management intervention.
Objectives: 1. Undertake a review and Cost Benefit Analysis (CBA) of over-abundant seabird population management strategies. This will be a project Stop/Go point to assess whether egg oiling provides the best management option for Silver Gull population control, and will determine whether the project proceeds as planned. 2. Estimate Silver Gull population size and structure through counts of breeding pairs (nest) and juveniles at up to five islands near Southern Bluefin Tuna aquaculture operations. Compare estimates with historical information for population trend analyses. 3. Obtain estimates of breeding success from oiled (treated) versus non-oiled (control) Silver Gull nests for use in population modelling. 4. Quantify short term effects of egg oiling on juvenile abundance, through measurement of the ratio of juvenile to adult Silver Gulls present at Southern Bluefin tuna aquaculture farms over three years and assess this indicator's efficacy in providing evidence of egg oiling management. 5. Assess Silver Gull breeding schedules, movement and habitat use within the study area. 6. Develop population models to assess the sensitivity of Silver Gull populations to reductions in breeding success from egg oiling and inform ongoing management targets for Silver Gull population numbers.

Globally, aquaculture accounts for over 50% of fish production. However, if poorly planned, rapid expansion to meet the ever increasing demand for seafood brings with it an environmental risk associated with eutrophication and organic enrichment of the seabed, adversely affecting marine coastal ecosystems.

However, if poorly planned, rapid expansion to meet the ever increasing demand for seafood brings with it an environmental risk associated with eutrophication and organic enrichment of the seabed, adversely affecting marine coastal ecosystems. Approximately 75-85% of the nitrogen discharged from finfish aquaculture is dissolved and dispersed to nearby habitats. A major spatial constraint on aquaculture in nearshore areas around much of Australia is the potential for these dispersed nutrients to negatively affect seagrasses. Seagrasses can be sensitive to increases in nitrogen, which can lead to habitat loss. This loss can have significant environmental and economic impacts with potential losses of ecosystem services including decreases in commercial and recreational fisheries catches, increases in sand instability and erosion, reduced biodiversity, loss of nitrogen assimilation and cycling, and loss of carbon sequestration.
In other situations, small increases in nutrients may have a positive effect on seagrasses, and thus it is not clear what the consequences of aquaculture derived nutrients will be. Subsequently, we can’t robustly determine the level of finfish aquaculture that can be sustainably supported by seagrass ecosystems. There is therefore a need to develop a process to determine the likelihood of seagrass growth (or loss) due to aquaculture derived nutrient inputs. This work will develop metrics that can be used in other aquaculture developments and in long-term regional monitoring.
Clean Seas Seafood Pty Ltd are developing a new lease for the sea-cage aquaculture of 4500 tonnes of yellowtail kingfish (YTK) in the Fitzgerald Bay region. The nearshore habitats throughout the region are dominated by long-lived Posidonia seagrass. While Fitzgerald Bay was the original focus of YTK aquaculture in SA, it has not been utilised for ~10 years, essentially giving us the potential to study this system prior to the commencement of aquaculture (currently planned for ~ July 2019), as well as while production is increasing, and it thus provides an ideal case study for assessing how to sustainably farm finfish in a seagrass dominated ecosystem.
Objectives: 1. Determine cost-effective approaches to assessing the influence of finfish aquaculture derived nutrients on seagrasses, and using Fitzgerald Bay as a case study, what that influence is. 2. Develop a predictive modelling ability to estimate carrying capacity and allow scenario analysis of future aquaculture development and how it might affect seagrasses, to allow managers to make informed decisions about where to place future developments, and how much to allow existing developments to expand. 3. Use Fitzgerald Bay as a case study to document seagrass condition using a range of metrics both before the commencement of finfish aquaculture, and once production has reached a substantial level. 4. Develop a range of cost-effective indicators for monitoring the effects of aquaculture on adjacent seagrass beds. Read moreRead less

Using mixed methods, this project aims to develop knowledge partnerships with Indigenous communities in three regions across northern Australia to build on understandings of how to respond to alcohol misuse more effectively, ensuring that alcohol is managed in ways that are relevant and useful to communities in a wide range of contexts. Alcohol is a major cause of social, legal and health concerns for Indigenous Australians. This has led to significant political involvement in the regulation of alcohol in communities where Australian Indigenous people live. Alcohol management plans have most recently been used as a central device for reducing alcohol-related harms, particularly in remote areas. The project case study results may provide significant benefit at the community level, empowering community groups to effectively engage in and respond to alcohol-related harms.Read moreRead less
