The release of the first SAFS reports in 2012 demonstrated the value and impact of national fisheries reporting. In order to build on this and establish a strategic, longer-term legacy it is critical that the process is evaluated and the next edition planned. The current proposal is critical to developing the mechanisms needed to establish the reports as on-going and build towards the broader elements of national fisheries status reporting.
This proposal builds on the investment in the inaugural reports, facilitating feedback from end-users and those directly involved in production. It also provides a forum for agreeing on processes for the second edition of the SAFS reports (tentatively scheduled for 2014) and future companion reports that will contribute to establishing national fishery status reporting.
While the initial reports focused on target species, there is a longer term need to build reporting frameworks on other aspects of Ecologically Sustainable Development (ESD), such as the effects of fishing on the marine environment, economic performance, governance and/or social good. Elements of this are already underway through complementary projects, and this proposal will identify and focus on the key gaps.
Complimentary projects with a national focus on fisheries include:
2010/061 ‘Development of a national harvest strategy framework’ (PIRSA)
2013/023 ‘Develop a draft Australian Standard for responsible fishing on vessels to improve public perception of the commercial fishing industry’ (SSA)
2012/746 ‘Seafood CRC: preliminary investigation of internationally recognised Responsible Fisheries Management Certification’ (Sydney-Fish-Market)
2013/024 ‘Professionalising industry - NSW pilot’ (Oceanwatch)

With the continuing recovery in the size of Australian-based fur seal populations post-sealing, a corresponding increase in seal interactions with domestic fishing vessels is occurring and will continue. There is an urgent need to develop effective seal bycatch prevention procedures to prevent fishing operations from being severely curtailed, or closed down, under the Environment Protection and Biodiversity Conservation Act 1999.
Following the 1999 winter blue grenadier season, incidental seal mortalities emerged as a major issue that threatened the continuation of this fishery; at least that part of the fishery harvested by factory trawlers. These trawlers had successfully developed the fishery, increasing the total grenadier catch from about 3000 t in 1996 to over 9000 t in 1999. The processed value of the factory trawler catch is now around $20 million per year (ASIC 2003) at first sale. The seal deaths in 1999 resulted in significant pressure from some environmental groups to prevent factory trawlers access to this fishery in 2000. This action would have caused significant loss of income in this sector and possibly jeopardised the future participation of factory trawlers in the fishery. There is a strong need for such vessels to demonstrate that seal bycatch can be reduced by adopting appropriate fishing procedures and gears.
It is also likely that pressures will be brought to bear on the ‘wet boats’ fishing for blue grenadier and possibly the rest of the SEF trawl fleet to take measures to reduce incidental seal captures. The study by Knuckey et al. (2002) indicated seal bycatch to occur virtually across the whole multi-species trawl fishery. Some of the results of the development and testing of SEDs and other mitigation measures by the factory trawlers in the targeted ‘single-species’ fishery under this project may be transferable to other vessel operators in the wider multi-species fishery, helping them to avoid many potential operational problems and costs. Increasing the effectiveness of SEDs in both reducing seal mortalities and minimising fish losses would be an important step in helping to gain wider industry acceptance of the potential use of these devices.
1. To improve the effectiveness of Seal Exclusion Devices (SEDs) in blue grenadier trawl nets in reducing seal mortalities and minimising losses of fish.
2. To assess the effectiveness of fishing techniques aimed at minimising seal bycatch.
3. To gather full biological information from all seal fatalities.
4. To achieve full observer coverage of freezer-trawler activities during the 2001 and 2002 winter grenadier fishery and monitor seal numbers around vessels and all seal-trawl interactions.
5. To gather information on seal movements/residence time in the winter grenadier fishery.

Introducing a Code of Fishing Practice aimed at avoiding seals appeared to halve the incidence of seal bycatch in this fishery. In SED trials, the problems of fish-loss via the SED escape hatch and net blockage via the SED grid were solved by changes in SED design. Although the effectiveness of most SED designs in reducing seal bycatch could not be quantified, the forward facing, ‘top-hatch’ SED design used in 2002 significantly lowered the incidence of seal bycatch in midwater trawl nets. Trials with this design are continuing. Some of the major factors that influence the probability of seal bycatch occurring in this fishery were delineated. Biological sampling of seal fatalities showed the dominant seal bycatch to be sub-adult male Australian fur seals habituated to foraging from trawl nets. Seal tracking studies developed a novel method of tagging seals at sea and indicated that a comparatively small and intransient sub-set of their population interacted with this fishery.
The following recommendations were made in the winter grenadier fishery: use open, forward-facing, ‘top-hatch’ SEDs (or a more effective design if one is developed) in all midwater net shots (or as directed for research purposes); continue the Code of Fishing Practice; continue the shot-by-shot recording of seal bycatch in the SEF1 logbook and maintain a level of scientific observer coverage and biological data collection; and, continue trials of the ‘top-hatch’ SED and gather more information by using underwater filming on the timing and depth–frequency of net entry by seals, and the circumstances of net entry that place seals at risk.
The following recommendations were made in the rest of the SEF trawl fleet: Priority should be given to assessing the nature and extent of seal-fishery activities across the fishery; The Code of Fishing Practice should be followed where practicable; and, At this juncture, SED use should be confined to large midwater trawl nets in areas where seals are known to be common, as more assessment of SED effectiveness is needed before extending their usage.
Project results also assisted the goal of obtaining accreditation for the SEF under a Section 33 determination under this Act.
