People development program: 2014 FRDC Visiting Expert Award- Dr Dan Gwinn
Dan Gwinn is an internationally renowned quantitative ecologist with technical expertise in several key areas that will benefit the management of Australia’s fisheries. Of particular interest to FRDC are his expertise in parameter estimation, monitoring design, and fisheries modeling. Dr Gwinn is experienced in developing innovative estimation methods to specifically deal with the inherent issues with imperfect data as is the case for fisheries and ecological research. Dr Gwinn’s work in this area has focused on the customization of statistical models to account for the specific idiosyncrasies of data sets to best extract biological information and inform the management decision process. Often, this work had included developing innovative analyses of existing data sets to answer new questions. Dr Gwinn also has expertise in use of analysis tools including the application of stochastic simulations for evaluating and optimizing experimental and monitoring designs, which are particularly useful for determining the most fiscally efficient sampling designs for meeting monitoring objectives.
We propose to facilitate a study tour for Dr Gwinn to enable him to meet with fisheries researchers and managers from several jurisdictions to review and discuss key freshwater and marine projects, present to the research and management community on innovative methods being employed in the United States to address common issues, and workshop strategies to enhance adoption of R&D outputs.
We believe that this visit will deliver significant benefit to the future management of Australia's fisheries resources.
People development program: FRDC Indigenous development scholarship - Angela Jeffery
Final report
The aim of this project was to develop a better understanding of Aboriginal fishing practices (past and present) through the development of educational materials.
This was to be undertaken as on-the-job training while working at Fisheries Victoria’s Marine and Freshwater Discovery Centre (MFDC) and, as a result of this scholarship, by researching indigenous fishing methods at the National Museum of Australia.

Tactical Research Fund: Development of a plan to address national needs for recreational fishing data for fisheries management and development
Governments and industry have recognised the importance and potential for further development of the recreational fishing sector. However, to increase and measure the social and economic values of the sector, and to ensure sustainability of the fisheries, there is a need to effectively and efficiently collect, curate and share appropriate recreational fisheries data. A systematic national approach to the collection and management of recreational fisheries data would also assist with the management of the sector and prediction of the impacts of regulatory decisions and program implementation.
A systematic and coordinated approach to the collection and sharing of recreational fisheries data for fisheries management and industry development are common themes in the:
- FRDC research and development plan to 2010
- Australian Fisheries Management Forum (AFMF) 2006-2008 research priorities
- 2006 State of the Marine Environment Report (SOMER2006)
- Fisheries Statistics Working Group’s “strategy to improve the quality, comparability and availability of fisheries data and statistics in Australia”.
The approach proposed here recognises that the 2000 National Recreational and Indigenous Fishing Survey provided information that, while useful and widely used, did not address many industry and government needs and is unlikely to be repeated. As a result, each jurisdiction is independently collecting recreational fisheries data for stock assessment, resource allocation and other management requirements.
Late in 2006, all jurisdictions and industry agreed on the need for a coordinated national approach to collection of recreational fisheries data. Since then AFMF’s Science and Research Sub-committee has been liaising with Recfish Australia and Recfishing Research (FRDC 2007/227) concerning a national approach to data collection and management that meets the needs of government and industry. There is strong support for the development of a national recreational fisheries data plan based on the respective and combined needs of government and industry stakeholders.
Final report
Selectivity and bycatch reduction of tiger flathead and eastern school whiting nets in the Danish seine fishery
Discarding is a major problem facing commercial fisheries worldwide. Discarding is wasteful and may
pose a threat to marine systems. It increases fishing costs through time spent sorting, damage to gear,
increased drag causing increased fuel costs, and, ultimately, may affect the ecosystem on which target
stocks rely. From ecological and economic perspectives, there is therefore a need to reduce, and where
possible eliminate discards.
ISMP data show that a large portion of the total catch by Danish seiners is discarded, particularly when
targeting eastern school whiting, for which the minimum mesh size is 42 mm (compared with 90 mm for
otter trawlers).
While work has been done to investigate modification of board trawlers, little work has been focused on Danish seine gear.
This project aims to determine the selectivity of Danish seine gear and trial appropriate gear
modifications that would maintain current commercial yields but reduce discarded bycatch.
