Need

It is proposed that a national workshop is needed to: (1) explore options to improve the precision and cost-effectiveness of recreational fishing surveys; (2) consider the use of emerging technologies to support recreational fisheries science; and (3) identify engagement strategies.

Although all States are expected to benefit from the outcomes of the proposed workshop, South Australia is particularly reliant on the shared expertise, transfer of knowledge and advice regarding the execution of scientifically robust, routine recreational fishing surveys. The South Australian Government is committed to undertaking a recreational fishing survey every five years. All previous surveys have been carried out by interstate experts, however, there is a commitment by PIRSA/SARDI to develop recreational fisheries science capability at a sufficient level to undertake all future State-based surveys. It is expected that the workshop will establish South Australia’s role as an active participant in the national assessment of recreational fisheries, increase data harmonisation opportunities across the jurisdictions, and contribute in advancing recreational fisheries science.

Objectives

1. Identify options to improve the precision and cost-effectiveness of recreational fishing surveys
2. Identify strategies that positively engage the recreational sector in fisheries science and management.
3. Assess whether emerging surveillance technology can be feasibly integrated into future surveys.

Summary

Currently, the most significant gap in our knowledge in assessing the status of community-shared fisheries is determining the relative contribution by the recreational sector. To explore this issue, a two-day national workshop was held from 10-12 July 2018 at the South Australian Research and Development Institute (SARDI). The key focus was advancing the ‘best practice’ approach in design, execution, and analysis of recreational fishing surveys as described in Georgeson et al. (2015; FRDC 2007-014). This project also builds on recent work by Griffiths et al. (2014; FRDC 2011-036) and Moore et al. (2015; FRDC 2012-022.20). The overarching aim of this workshop was to assess the usefulness of new technologies and techniques for enhancing the cost-effectiveness and reliability of recreational fishing surveys. The attendees included recreational fisheries scientists, managers, a national peak body representative, an international expert, representatives from Deckhand© and a Fisheries Research and Development Corporation (FRDC) representative. 

The specific objectives of the workshop were to:

1. explore options to improve the precision and cost-effectiveness of recreational fishing surveys;

2. assess whether emerging technologies can be feasibly integrated into future surveys; and

3. identify strategies that positively engage the recreational sector in fisheries science and management.

Seafood CRC: optimising the size and quality of sardines through real-time harvest monitoring

In order to improve the commercial profitability and sustainability of the South Australian Sardine Fishery (SASF) there was a need to establish improved monitoring and harvest management practices based on an understanding of Sardine habitat preferences. In this project, the South Australian...

Validating a new sampling technique for estimating egg production

Estimates of spawning biomass obtained using the Daily Egg Production Method (DEPM) are the primary biological performance indicator in the South Australian Sardine Fishery (SASF) and Commonwealth Small Pelagic Fishery (SPF). The DEPM is also being used to assess the status of other...

Mud cockle (Katelysia spp.) stock enhancement/restoration: practical implementation and policy evaluation

This study was conducted to restore the Mud Cockle population in the Section Bank of Port River, South Australia, which had drastically decreased due to commercial fishing. Mud Cockles are important not only for commercial purposes but also for stabilizing sediment and reducing turbidity in the...

Distribution of benefits between commercial and recreational fishers from policies implemented to control fishing effort in commercial fisheries: An application to the Coffin Bay King George whiting fishery

Recreational boat fishers using the Coffin Bay boat ramp between January and June 1990 were interviewed to obtain information on their fishing activities. Recreational boat fishing is an important activity in Coffin Bay. The majority of fishers targeted King George whiting (Sillaqinodes punctata),...

Need

Conflicts between LCF gill net fishers and Long-nosed Fur Seals have escalated in recent years with the reported level of fur seal depredation of caught fish from, and damage to, gill nets now jeopardising the economic viability of the fishery. Representatives from the LCF estimate that fur seal depredation has reduced fishery production by approximately 25%. In 2012/13, a commercial LCF licence holder documented production losses of $76,000 over a 5 month period. At the same time, 19 other licence holders were experiencing similar or greater losses. Industry estimates that fur seal interactions are costing the fishery a wharf value loss of $2 million. Industry now questions whether the fishery will be viable in five years if alternative management strategies or options are not found to mitigate the impacts of interactions.

The need for alternative fishing methods and/or deterrent systems to reduce the impacts of fur seal depredation on the fishery is urgent, given the increasing economic impacts to the LCF fishers and the local communities that rely heavily on the fishing industry.

Objectives

1. To undertake a review of global seal and fisher interactions and to review best practise mitigation and management options relevant to the Lakes and Coorong Fishery.
2. To assess operational changes to current practices, including the use of deterrent methods to reduce the rates of seal depredation on caught fish and damage to fishing gear.
3. Develop and trial alternative fishing gears/methods based on best practice that are less vulnerable to seal depredation of catches and gear damage, and provide economically viable alternatives to current practices.

Summary

This report assesses the efficacy of alternative strategies for managing seal-fisher interactions in the gillnet sector of South Australia’s Commercial Lakes and Coorong Fishery (LCF), including the use of deterrents and alternative fishing methods. It uses a range of information obtained through fishing trials undertaken by commercial fishers in areas of the LCF to assess: (1) the efficacy of seal crackers (a type of seal deterrent) for reducing fur seal impacts on LCF gillnet fishers; and (2) the operational effectiveness of three fyke nets and two haul-net techniques as potential alternatives to existing gillnet practices. Findings have led to key management outcomes for industry, including access to crackers as a tool for mitigating seal interactions; and provide a source of information for on-going discussions about approaches for improving the economic viability of the fishery.
