Need

Currently there is a lack of national scale, consistent and robust data on the motivations and behaviours of recreational fishers, and lack of robust data on the social and economic contribution of recreational fishing. 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

Summary

The NRFS involved three stages of data collection. An overview of the three stages of data collection and the purpose of each, and a guide summarising which chapters draw on data from each stage of data collection, are provided in the next section. Sections 3.4, 3.5 and 3.6 provide a detailed description of the methods used to collect and process data in Stages 1, 2 and 3 respectively. These sections explain, for each stage:
  • The purpose/objectives of data collection
  • Data collection methods, including design of survey instruments and survey recruitment materials, survey sample recruitment methods and sample achieved
  • Data processing methods, including data coding and cleaning, and weighting methods.

Summary

The outbreak of white spot disease, caused by white spot syndrome virus (WSSV) (Whispovirus sp.), in South-East Queensland (Qld) in 2016–17, the recognition of new and emerging diseases, and advances in scientific knowledge since the release of the Generic import risk analysis report for prawns and prawn products 2009 (the Prawn IRA; Biosecurity Australia 2009) highlighted the need to review the biosecurity risks of prawns imported into Australia (the prawn review).

 

The Prawn IRA 2009 considered that the regular introduction of imported prawns, intended for human consumption, into the aquatic environment, through use as bait or berley presented a significant pathway for exposure of Australian crustaceans to imported prawns potentially infected with hazards. Surveys conducted in 2002 and 2007 investigating the use of prawns, intended for human consumption, as bait or berley provided significant data inputs for the Prawn IRA 2009. There had not been national surveys conducted since that time. Therefore, it was identified that the prawn review needed current data on the use of prawns as bait or berley to ensure the conclusions were based on current information. Questions to characterise the extent of the use of prawns purchased from seafood retailers as bait and berley by recreational fishers in Australia were nested within the 2019-20 National Recreational Social and Economic Survey of Recreational Fishers (Moore et al. 2023).

 

Results from this survey indicate that prawns were the most popular bait used by recreational fishers over the survey period, followed by various kinds of saltwater fish and cephalopods (octopus/squid/cuttlefish). While prawns were the most popular bait type nationally, there were differences at the jurisdictional level, with recreational fishers in Western Australian, Tasmania and the Northern Territory most commonly using cephalopods, while South Australian fishers most commonly used ‘other shellfish’.

 

Of the respondents who reported using prawns as bait and/or berley, 85% indicated that they had bought prawns from a bait supplier, while 20% indicated that they had bought prawns from a seafood retailer (some respondents reported purchasing prawns from both sources). Uncooked whole prawns were the most common prawn type purchased from a seafood retailer, with most respondents indicating that they had purchased a total of less than 1 kg over the previous 12 months. Most fishers reported using Australian origin prawns, but some reported using imported prawns or that they were unsure of the origin of the prawns they were using as bait.

 

To test whether recreational fishers are aware of the risks of using imported prawns intended for human consumption as bait, the survey also asked recreational fishers if they had seen advice regarding the use of imported seafood prawns as bait and berley. Almost half of all respondents said that they had seen advice regarding the use of imported seafood prawns as bait and berley, with the highest levels of awareness in Queensland and the lowest in Victoria.

Need

Difficulties with current legislation in Australia at State and Federal level make it challenging for marine farms to protect themselves, but equally for the community to have faith that aquaculture development is not harming the marine environment. An example from Tasmania is the recent contamination of Macquarie Harbour, whereby tailings from Copper Mines Tasmania (CMT) dam in Queenstown entered the harbour and undoubtedly caused environmental harm to salmon and other species. Because CMT and salmon farmers operate under different Acts CMT was not responsible for the incident but rather the government. Consequently, no investigation or clean-up ensued.

Additionally, the scope of statutory tools, such as EIS under the Tasmanian Marine Farm Planning Act 1995, is not regional and does not consider the compound interactions of and on production activities. A good example is the recent Storm Bay salmon farming expansion; while the EPBC listed handfish species in Tasmania were listed in the marine farming development plan, with a brief context, management of these species was not considered in the EIS because that process only includes direct impact of the lease position. Arguably, cumulative impacts from all development in the area will have varying impacts on the species, impacts which are not being considered under current government legislation, but are potentially the source of public ire.

For aquaculture to pursue sustainable efforts environmentally, economically and socially in the increasingly crowded near shore space requires proactive planning and transparency that is not currently possible given existing assessment tools. In particular, assessment of cumulative impacts must be addressed. Cumulative impact assessments (CIA) are gaining momentum across multiple industries due to a recognised need to apply them in the pursuit of sustainable management. CIAs are being undertaken with the protection of marines resources at front of mind, but so far there has been little consideration of aquaculture. An approach to CIA that makes aquaculture the centre point is required if we are to consider its impacts or conversely, its effectiveness.

Objectives

1. Identify the risks of multiple actions or impacts on the environment and social values of a marine production matrix in Australian waters. In order to do this a comprehensive literature review is required to develop the CIA approach and ensure the methods and gaps in aquaculture CIA are addressed to meet the needs of Australian aquaculture, the community and the consumer.
2. Develop a risk assessment tool that can be utilised by the public realm (governments at all levels, NFPS, community) to better understand the complexities of regional marine waters and user impacts to maximise current and future economic, social and environmental benefits. To do this requires identification of valued environmental and social components first, whereby such components are characterised, from this a framework is build on each valued component.
3. Assess aquaculture in the context of broader social and environmental issues within the marine production matrix, by performing an aquaculture specific cumulative impacts assessment for regional Australia
