Optimising Compliance Outcomes in Recreational Fisheries

This study investigated strategies to enhance compliant participation among recreational fishers, using the Peel-Harvey Blue Swimmer Crab fishery in Western Australia (WA) and the Blue Swimmer Crab fishery in South Australia (SA) as case studies.

Assess causes and implications of anomalous low lobster catch rates in the shallow water areas near the centre of the Western Rock Lobster fishery

Current and former West Coast Rock Lobster Managed Fishery (WCRLMF) fishers have anecdotally observed a trend of low catch rates since the 1990’s in the near-shore shallow water areas (<8 m) near the centre of the fishery (Dongara-Leeman). Since the atypically low puerulus counts of...

Need

National reviews of Fisheries R&D needs (FRDC95/055) have identified the need for non-extractive, fishery-independent sampling and stock assessment techniques which are cost-effective, repeatable and robust across and range of habitats and depths. These methods are becoming increasingly important as Australian fisheries face the challenge of addressing ecosystem based fisheries management and climate change. A national workshop on the use of video for sensing the size and abundance of target and non-target fauna in Australian fisheries (FRDC2000/187) highlighted the potential for Baited Remote Underwater Video systems (BRUVs). After a decade, there has been wide adoption of this technique. However, differences in protocols for deployment, analysis and interpretation make spatial and temporal
comparisons of data difficult.

There is the need to develop a robust set of nationally agreed upon protocols to ensure that users are appropriately informed and trained through a comprehensive extension and capacity building program that also identifies key unresolved technical issues.

With the increased testing and use of BRUVs a number of independent developments have occurred. Future technological advances and more detailed statistical and modelling approaches will result in the BRUVs data being more useful for ecosystem assessment and management. Maximising the potential that these advances will provide to Australian fisheries will be achieved by a co-ordinated and
collaborative research strategy. We propose to host a two day workshop to critically evaluate the use of BRUVs as a data collection tool
for scalefishes and sharks. The workshop will identify the strengths, limitations and identify potential solutions.

Objectives

1. To critically evaluate the strengths and limitations of data collected with BRUVS for detecting changes in the relative abundance, length frequency and community composition of scalefishes and sharks.
2. To identify potential solutions to limitations.
3. To develop a nationally agreed to protocol for the deployment of BRUVs and the analysis of the resulting imagery.

Tactical Research Fund: Economic assessment of the impact of recent major changes to fisheries management in the WA West Coast demersal wetline fishery

Need

The West Coast demersal wetline fish stocks are currently overfished. The best assessment calls for an immediate 50% reduction in the catches of Category 1 “high risk” species.

New management initiatives are being implemented across the commercial, recreational and charter sectors to secure the necessary catch reductions. The success of these initiatives depends upon each sector responding appropriately.

Early assessment of the impact of these changes and the response of each sector is essential. The time for this assessment is now, as the changes begin to take effect, in order that an early understanding of the reactions of fishers and the likely long-term impacts can be formed.

The new restrictions will impact significantly on recreational fishing over the next year, therefore, there is a pressing need to understand how the sector responds in terms of behaviour, catches, and overall satisfaction with the fishing experience. The proposed recreational fisher survey is designed to meet this requirement, so that the early operation of the new regime can be measured, and compared to the pre-change situation captured in a similar survey funded under FRDC 2001/036 undertaken by Nicholls and McLeod. Knowledge about changes in behaviour and satisfaction with the fishing experience are crucial to understanding the impact of the changes.

Department of Fisheries estimates show that the commercial catch has been brought within the desired range. There is now a need to assess how these changes have impacted upon the commercial viability and social dynamics of coastal harbour towns. No pre- and post-change comparisons have been undertaken, a deficiency that the proposed data collection is designed to address.

The role of the Charter sector and its response to management changes is an integral part of the project.

All components of the project are designed to deliver the required information in a timely fashion.

Objectives

1. Determine the change in profitability of commercial wet line vessels operating in the west coast wet line fishery under the new management arrangements for the 3 year period 2004-07 (prior to the new arrangements) and 3 year period (FY 2008-11) after their implementation.
2. Determine the range in responses of a sample of charter boat owners and their clients to the fishery management changes introduced in the west coast wet line fishery in 2009 (interim and additional) and the impact on client satisfaction and on their businesses
3. Determine the range in responses of a sample of recreational fishing boat owners to the fishery management changes introduced in the west coast wet line fishery in 2009-11 (interim and additional) and the impact on the frequency of their fishing activities in the 2008-12 period
4. Conduct a socio-economic impact assessment of the three sectors as a result of fishery management changes introduced and a scenario analysis of the likely impact of the alternative management options on 3-4 West Coast study towns with boat harbours
