FishPath: Tailoring Management to Context in Data-Limited Fisheries
A number of fisheries in Australia are characterised as being 'small scale', 'data ' and/or 'capacity' limited (hereafter small scale fisheries). Fisheries management within the context of small scale fisheries is often ad hoc and is resource intensive relative to the value of the fishery in question. An existing project (FRDC 2015-213) is developing guidelines for low cost and systematic management of small scale fisheries. A central component of those guidelines is the FishPath tool developed by CSIRO in partnership with a global consortium of experts.
The FishPath tool has significant potential for adoption as a 'standard' approach to small scale fisheries management in Australia and has strong stakeholder by-in at a theoretical level. However, the implementation of the guidelines and the FishPath tool would benefit from testing to optimise that potential. To be effective, the tool needs to provide a framework for participatory discussions about what management, harvest strategy and longer term monitoring and assessment options are best suited to a given fishery.
As a part of the existing project, a workshop has been scheduled to occur in Darwin on November 17 2017. At that workshop, a project team that will be led by Natalie Dowling (Principal Investigator 2015-213) and Kate Crosman (Evans School of Public Policy and Governance at the University of Washington) plan to introduce, test and improve the FishPath tool by focusing on stakeholder input. The existing project budget will enable the workshop to proceed with NT-based stakeholders in attendance. However, the potential value of the tool in a national context warrants broader participation. This proposal seeks support to fund the participation of key stakeholders from regional areas of the Northern Territory (e.g. Gove) and around Australia to ensure broad issues are considered and outcomes are provided against national priorities to improve productivity and profitability of small scale fisheries and in assistance to the Status of Australian Fish Stocks program.
The outcomes of the workshop are regarded as essential to determining the next phase of work in the implementation of the management guidelines and FishPath nationally.
Final report
Fisheries are increasingly managed with involvement of fishers and other stakeholders. Stakeholders are especially critical where managers lack full knowledge of the system to be managed, resources to gather additional information, and/or resources to monitor and enforce compliance. Such ‘data-limited fisheries’ comprise more than 80% of the total global fish catch and face challenges to maintaining sustainable harvest rates. Sustainable management of data-limited fisheries may be improved by decision support that informs assessment and management choices and that is available to fishers and managers. Here we report results from a field experiment conducted with Australian fisheries stakeholders. The experiment tested FishPath, an interactive decision-support software tool for data-limited fisheries, and its influence on stakeholder buy-in to management. Participants were provided with a hypothetical fishery that mimicked commonly encountered real-world data- and capacity-limitations. In Stage 1, to establish baseline levels of buy-in, we presented participants with a shortlist of management options tailored to the fishery; participants did not interact with FishPath. In Stage 2, to test the effect of FishPath use, participants collectively input the hypothetical fishery into FishPath; the tool then presented the same management options seen in Stage 1. In Stage 3, to assess the effect of expert support, participants were randomly assigned to a control group and a treatment group after a common introduction to FishPath output. The control group explored the output without additional support, while the treatment group explored output with support from a FishPath expert. After each stage, participants were asked to rate: 1) their support for an ongoing process to select management options from the shortlist; 2) how easy or hard they expected management of the fishery to be; and 3) how effective they expected management of the fishery to be. Initial findings indicate that while FishPath use does not significantly increase stakeholder support for management (possibly due to ceiling effects, as support was high in Stage 1), it does significantly increase participants’ perceptions of the ease and effectiveness of management.
Completing Australia’s First National Bycatch Report
In the recently completed project 2015/208 “Developing a National Bycatch Reporting System”, we derived estimates of bycatch and discards for 4 case-study jurisdictions (with associated variances) as well as metrics regarding the quality of the data used. The jurisdictions done were New South Wales, Tasmania, Queensland and the Northern Territory. But that work completed only half the story. This present project is to complete the task by applying the methodology developed in the previous project to the remaining 4 jurisdictions: The Commonwealth, Victoria, South Australia and Western Australia. By adding estimates from these jurisdictions to those derived earlier, this current project will produce the first complete, national bycatch report for the country. An advantage with this approach is that the new project will only cost a fraction of that of the previous project because most of the development work is complete. The result will be Australia's First National Bycatch Report and a process by which Australia's (and the world's) stakeholders can monitor and track Australia's management of bycatch. This should improve the standing of our fisheries internationally, to various eco-labelling organisations and the general public.
Final report
Bycatch (non-targeted organisms that are unintentionally caught when fishing for particular species or sizes of species) remains an important issue concerning the world’s fisheries. Discards are considered the most important component of bycatch because they represent a perceived wastage of seafood resources as well as the potential to include Threatened, Endangered and Protected Species (TEPS), attracting significant interest and controversy from many stakeholders. There is now growing acceptance and international, regional and national agreements and instruments that encourage and/or require governments to report on the status of bycatches.
