Research is needed to investigate the development of an Akoya industry in WA
Limited trials of seeded wild Akoya shell have shown promising results and market feedback lead us to believe there is a very real opportunity for slightly larger Akoya of better quality. Port Stephens has built a successful Akoya industry and we would like to assess the commercial viability of this model in the Abrolhos area. The economics of farming Akoya appear attractive in terms of total cycle and husbandry costs when compared with black pearls and offer the ability to leverage our existing infrastructure into the new species creating economies of scale.

Part of the project involves developing broodstock selection protocols to choose desirable broodstock and create a broodstock conditioning system both on farm and in the hatchery. Research into the use of hatchery bred stock and development of broodstock selection protocols and broodstock holding and conditioning systems will be very beneficial to this developing industry.

The BCMI has a full time hatchery technician that will assist in developing these protocols. This technician has limited experience of other hatcheries and the project proposes to build the knowledge base of the technician through hands on supervised experience at 2 East Coast hatcheries. This will improve the technical capacity of the hatchery facility to increase quality spat production.

There is a need to assess the impact of the environmental conditions at various farm sites on animal health, growth rates and pearl quality. Production costs must be managed carefully for the species to be commercially viable so site selection at various stages of the life cycle is important.

Objectives

1. Develop broodstock selection protocols for Abrolhos pearl oysters both on farm and in the hatchery to identify desirable broodstock (P.imbricata = P.fucata= P.martenesii) with the qualities demanded by the market
and establish a broodstock conditioning system for these oysters.
2. Transfer and integrate accepted knowledge to key BCMI staff from established hatcheries to improve technical capability at the facility, improving quality spat supply services for WA industry.
3. Produce spat from the selected Akoya host and saibo donor oysters in the hatchery and grow out in spatially diverse sites at the Abrolhos Islands to assess the viability of developing the industry on a commercial scale. Pre-seeding conditioning trials will also be undertaken.
4. To investigate the impact of environmental factors on key pearl characteristics including growth rate, mortality, shell size, lustre and nacre for Akoya (P.imbricata = P.fucata= P.martenesii) by monitoring spatially diverse growout sites at the Abrolhos Islands.

SESSF Industry Development Subprogram: adding value to an under utilised fish species (silver warehou)

Project number: 2007-209
Project Status:

Need

There is little opportunity for fishers in the SESSF to increase profitability. All major species have been allocated quotas, and there is little scope to increasing quotas with all species fully exploited or overfished. While much research has focused on the collection of biological data, assessment of the status of fish stocks and the impact of fishing on the environment (Knuckey 2004) there is a need to investigate value adding to species currently captured by the fishery.

Silver warehou is one of the most promising low-value species to trial for value adding. At present there is little demand from the consumer public with its off white colour when filleted, large catches of it are landed during winter months depressing the price. Many hundreds of tonnes of this species is currently discarded at sea due to lack of markets.

The cost of establishing new markets for both the flathead and school whiting were considerable and borne solely by Consolfish, though all fishers benefited from the higher prices. The products were so successful that Consolfish can no longer afford to process small to medium flathead as the high price at the wharf makes it unviable.

Silver warehou is a relatively unfamilar fish to oversees processors. This project is needed to develop a consumer friendly product and then organise the processing techniques, further training and production planning. The Thai processors have indicated they are keen to process the fish and the Woolworth supermarket chain have indicated they will be willing to stock it on a trial basis. Promotion of the product will be required and will be undertaken at Consolfish expense.

Objectives

1. Conduct research to confirm appropriate markets for this seafood product
2. Develop a new seafood product from silver warehou that will appeal to the consumer and is competitively priced to similar imported products
3. Adapt equipment to process silver warehou into suitable products
4. Establish training program for processing staff to ensure product QA
5. Desribe how the process applied to silver warehou can be adapted to other low-value species

SESSF Industry Development Subprogram: alternative fuels for fishing vessels

Project number: 2007-200
Project Status:
Completed

Need

With most of Australia's fish stocks at fully fished or overfished status, there is reduced opportunity for increasing economic returns from larger catches or unexploited resources. As a result, the fishing industry is looking for opportunities to increase its profit margins by reducing the cost of fishing. Generally, fuel is the one single highest operating cost to fishing vessels, accounting for up to 50% of the operating costs of a fishing vessel in Australia.

The Australian (and New Zealand) Fishing Industry requires assistance in becoming a more efficient user of energy. Some forms of fishing, such as trawling, expend more fuel per kg of fish landed compared to passive methods such as longlining and trap fishing. In all cases however, rising fuel prices impinge on the profitability of the operations, and ultimately put their viability in jeopardy; this has reach a critical situation for many operators in Australia.

The R&D plans and strategies of all advisory bodies to the FRDC contain high priority goals to achieve FRDC’s Industry Development goal (planned outcome):, The commercial sector of the Australian fishing industry is profitable, internationally competitive and socially resilient. This investigation into alternative fuels for the fishing industry, some of which also achieve lower greenhouse gas emissions, has the intention of improving the economic viability of fishing enterprises and shifting the industry towards a more secure position with respect to future fuel needs.

Objectives

1. Demonstrate the feasibility of Marine Gas Oil (or other lower cost distillates) in fishing vessel engines, as a cheaper form of petroleum based diesel fuel.
2. Investigate the technical feasibility of fishoil as a biofuel source related directly to the activities of the industry.
3. Evaluate LPG as a relatively user friendly option with established supply chain, and detail the required technology in the context of fishing vessels.
4. Evaluate natural gas (LNG, CNG) as a prospect for significant fuel cost savings, and detail the required technology in the context of fishing vessels.

Tactical Research Fund: Rapid response to abalone virus depletion in western Victoria: information acquisition and reefcode assessment models

Project number: 2007-066
Project Status:
Completed
Budget expenditure: $70,000.00
Principal Investigator: Harry Gorfine
Organisation: University of Melbourne
Project start/end date: 28 Feb 2008 - 1 Oct 2008

Need

The workshop review concluded that (1) there are significant gaps and limitations in the existing information on the status of the abalone populations across reefs in western Victoria (West and Central zones) and exposure of these populations to the virus and (2) that the current regional model was inadequate to represent the current situation in the western zone or to evaluate management options.

In relation to the information needs, it was concluded that there was an urgent need for a repeat of the scientific surveys at all the standard monitoring sites in the western zone, and far enough into the central zone to be ahead of the virus outbreaks, during July-August 2007. The standard sampling should be augmented by genetic sampling and broad survey of aggregations on the reefs.

The current quantitative regional model is not adequate to represent the current situation in the western zone or to evaluate management options. This is because the current situation in the western zone provides both a form of depletion that is very different from fishing, in terms of the size classes affected and extent of depletion. Reefs are affected differently and the management options are also likely to vary by reef, but the existing regional model does not represent reefs. Because the current situation is unique, there is no longer a basis for assuming that the previously-used industry-based semi-quantitative assessment of reef codes will continue to be reliable.

Thus there is a need to develop and apply a quantitative model that is spatially resolved to at least the reef-code level, and to use this for assessment of population status and examination of management options at the reef-code level.

Objectives

1. Conduct the scientific surveys at the DPIR reef-code sites, using the Victorian survey methods, augmented by genetic sampling and extended survey of the extent of aggregations.
2. Develop a long-term monitoring strategy for continued assessment of reef-stock status and management options.
3. Use existing models to broadly illustrate the likely impacts of the outbreaks.
4. Compile existing information on the outbreaks in an accessible, informative form, develop reef-code growth, maturity and abundance trajectories, and agreed catch histories.
5. Develop and apply a quantitative model that is spatially resolved to the scale of reef-codes, and use this to assess the status of populations and inform the Total Allowable Catch setting process.

Need

On 25 August 2005, the SA Government closed the SASF in response to results from independent observer coverage in the fishery and concerns associated with encirclement and mortality rates of common dolphin.

The SASF TEPS Code of Practice developed prior to the fishery has been effective in reducing the encirclement and mortality rate initially reported but still requires improvement to ensure the fishery is operating sustainably.

Recent communication between PIRSA and SAMSSIA in relation to interim results from the observer program (July 2006 – June 2007) has highlighted that improvement of the SASF TEPS Code of Practice is an immediate priority.

Investigations by the SASF TEPS WG suggests there is scope to develop an acoustic mitigation signature that will further reduce the encirclement and mortality rate of common dolphins and improve the effectiveness of the TEPS Code of Practice.

Considering the importance the SA Government places on effective TEPS mitigation the development of underwater acoustic mitigation technology presents the greatest potential to improve the SASF’s TEPS Code of Practice.

This project will address FRDC’s strategic challenge to improve the management and use of aquatic natural resources to ensure their sustainability; has a high likelihood of success considering the success of acoustic behavioral modification on similar species(Leeney et al 2007) and in relation to the common dolphin (Morizur et al 2007) and has a high likelihood of adoption by industry as a successful outcome will be incorporated into the TEPS Code of Practice which is adhered to by 100% of the licence holders in the fishery.

The SASF is a key economic driver in the region and all efforts to maintain and secure access rights through the adoption of sustainable fishing practices are warranted.

Letters of support for this project from PIRSA Fisheries and SAMSSIA are attached to this application.

Objectives

1. Determine the ambient sound levels in open water within the South Australian sardine fishery.
2. Determine and model the acoustic propagation rates for given pinger signals in open water in sardine environments and through sardine schools to determine the likely transmission loss and received signal level.
3. Identify the various acoustic characteristics of purse seine fishing operations, particularly to detect signal characteristics that differentiate between vessel steaming and the commencement of fishing activity.
4. Determine the acoustic characteristics of FM tones and the detection distance of directional broadband clicks for the common dolphin.
5. Identify the sound output parameters for acoustic pingers and additional output signals that will be appropriate for mitigation of interaction with common dolphin.
6. Assess the effect of acoustic pinger signals on sardine schools by monitoring sardine school integrity and compactness using available vessel sonar systems and qualitative assessments of fishing masters.
7. Complete two high capacity / long-term acoustic data loggers specifically to determine bearing-to- target vectors of FM tone and broadband click sound source generators (i.e. common dolphins).

Tactical Research Fund: Developing an analytical module for large-scale recreational fishery data based on phone/diary survey methodology

Project number: 2007-064
Project Status:

Need

The 2000/01 National Recreational and Indigenous Fishing Survey (NRIFS) yielded the first comprehensive assessment of recreational fishing in Australia. Core components were a telephone-based screening survey of households followed by a phone/diary survey in which fishing and expenditure was monitored.

From a methodological perspective, exceptionally high survey response rates, a comprehensive approach to non-response calibration and representation are features that have been recognised internationally as benchmarks for such surveys. However, the complexity of the NRIFS and sheer quantity of data collected meant that analysis was not straightforward and simple statistical approaches were not available.

Since the NRIFS, several jurisdictions have identified the need to provide on-going state-wide and regional information about their recreational fisheries, with the NRIFS methodology seen as cost effective in providing such information. For instance, Tasmania and SA will be conducting state-wide surveys in 2007/08 and Victoria and WA are undertaking regional surveys using the methodology.

While the efficacy of the phone/diary methodology in collecting detailed and robust data has been established, options for data analysis need to be developed and more fully integrated. Specifically, analytical routines need to interface directly with the databases and be flexible enough to enable a range of queries to be run efficiently and be repeatable. The development of an analytical module would represent a significant advancement in the provision of recreational data and will have immediate and on-going application in a number of jurisdictions. This project directly addresses AFMF and national recreational R&D priorities relating to assessment of non-commercial fishery impacts.

Objectives

1. Review and document statistical procedures for analysing large-scale phone/diary recreational survey data
2. Develop an integrated and flexible data analysis module for phone/diary recreational survey data
3. Undertake a re-analysis of key NRIFS data outputs
4. Roll-out and demonstrate the analysis module to potential users
