Need

Dramatic increases in the catch of albacore occurred in the ETBF in 2006 as several domestic longliners switched from targeting broadbill swordfish to albacore tuna landing the catch in Mooloolaba. These high catches were maintained in 2007, and given that localised depletion of albacore has been observed in several Pacific island nations, it raised concerns about the long-term sustainability of the fishery and highlighted the pressing need to implement a Harvest Strategy. Industry have stated that albacore is now an important component of the economic viability of the fleet.

To determine target reference levels for albacore consistent with the Commonwealth Harvest Strategy Policy, data are required on the size composition of the catch, size/age-at-maturity, growth rates, fecundity and mortality (Campbell et al., 2007). A feasibility study (AFMA 2006-826) specifically identified “the need to revise the size monitoring protocols for albacore, and potentially other target species, to ensure that this important input data stream for the ETBF harvest strategy is providing a consistent and unbiased sample of the size structure of the commercial catch over time”. In addition, the study identified the need to collect substantially more biological samples and undertake research on direct ageing and reproduction to address key biological uncertainties for albacore in the region. In August 2007, the WCPFC Scientific Committee re-iterated the priority for biological information on albacore and noted that this work has "strong assessment implications with wide-spread benefits to a number of fisheries active in the WCPO".

Acknowledging this, the ETMAC identified the collection and analysis of data (including size, sex composition and biological data) for the ETBF as its highest priority. In addition, the ETMAC explicitly identified the determination of life-history parameters and improved stock assessments for albacore tuna as a High Priority project. This proposal addresses both these high priority research areas.

Objectives

1. Design and implement, in consultation with Industry, a practical, cost-effective industry-based monitoring program for obtaining representative sized data for albacore in the ETBF.
2. In collaboration with SPC, develop a biological sampling program to ensure that unbiased estimates of biological parameters for albacore are also obtained for the southwest Pacific region.
3. Collect biological samples (otoliths, spines, gonads & muscle tissue) from at least 500 albacore caught in the ETBF in 2008/09.

Tactical Research Fund: Information to support management options for upper slope gulper sharks (including Harrison's dogfish and southern dogfish).

Need

The ecological risk assessment process recently undertaken jointly by AFMA and CSIRO has identified that sharks generally, are high priority species which require focussed management attention. In the Southern and Eastern Scalefish and Shark Fishery (SESSF) this is particularly the case for upper slope Southern and Eastern gulper sharks (including Harrison’s dogfish and Southern dogfish) which have been found to be severely depleted and have been nominated as threatened species under the EPBC Act. AFMA is now developing management responses to address these identified ecological risks, and there are a number of complimentary processes currently underway. These include the bycatch working group in the SESSF, which is currently preparing a bycatch work plan to be developed and implemented during 2008. AFMA is also establishing an expert shark and ray (Chondrichthyan) working group to develop appropriate management responses for these species across all fisheries. There is also a small working group in the South East Trawl Fishery (SETF) which is looking closely at the deepwater shark species of the lower slope and additional work is being undertaken to provide immediate management recommendations in relation to Harrison’s dogfish in particular. However, despite these various initiatives, there is a need to review available information on the upper slope gulper sharks (including species other than just Harrison’s dogfish) to improve understanding of levels of interaction and to provide advice on future management options.

Objectives

1. Review the success of management arrangements used elsewhere around the world to address the sustainability of fisheries catches involving similar upper slope low productivity shark species
2. Consider the historical identification of Harrison's dogfish including catch statistics and scientific surveys.
3. Investigate and improve estimates on the extent and nature of actual interactions with Harrison’s dogfish and other similar upper slope gulper sharks in all sectors of Australia’s SESSF
4. Provide an analysis, with supporting rationale, for alternative management options for reducing the ecological risk to Harrison’s dogfish and other similar upper slope gulper sharks in Australia’s SESSF

Tactical Research Fund: Management Strategy Evaluation (MSE) of the harvest strategy for the Small Pelagic Fishery

In 2008, the Australian Fisheries Management Authority (AFMA) developed a harvest strategy for the Commonwealth’s Small Pelagic Fishery (SPF) (AFMA 2008) in accordance with the Commonwealth Fisheries Harvest Strategy Policy (DAFF 2007). Before its completion, an independent review was conducted...

Tactical Research Fund: Co-management strategies for WA State Managed Fisheries using the Exmouth Gulf Prawn Trawl Fishery as a case study

Project number: 2008-059
Project Status:
Completed

Need

The Exmouth Gulf Prawn Fishery from 2008 will become a single operator fishery with M.G. Kailis Gulf
Fisheries Pty. Ltd., operating all licenses and trawlers in the fishery. An opportunity exists to assess the
value of Co-Management for the management for the fishery and for progressing certification under the Marine Stewardship Council through a ‘local self management’ governance model that reports to a locally based community advisory committee. This new direction in fisheries management is anticipated to improve flexibility in real time management, and reduce the burden on the Department of Fisheries for management, research and especially compliance and legislative action. Any self governance must also facilitate reporting of key performance indicators to meet and gain acceptance of fisheries managers and meet longer term reporting needs of the EPBC Act and the Marine Stewardship Council and the broader community.

The case study will provide a strategy for progressing the ‘local’ management of other Western
Australian fisheries, where the catch interaction with other sectors is minimal or where resource shares have been determined for competing sectors. The case study will also provide directions for legislation amendments to WA Legislation necessary to support co-management changes.

This work needs to be immediately undertaken as cabinet approval is being sought from the WA Government for amendments to the Fish Resources Management Act. There is limited time opportunity (about 12 months as drafting proceeds) for the case to be made to government for changes to legislation. Additionally the availability of the Principal Investigator beyond this window of opportunity cannot be guaranteed.

Objectives

1. Develop and assess the feasibility of a local co-management governance model for the Exmouth Gulf Prawn Fishery to serve as a ‘template’ for other WA State Managed Fisheries wishing to move to co-management.
2. Urgently identify any legislative amendment imperatives for the WA Fish Resources Management Act.
