Need

The WA FRAB has identified market intelligence and information as a priority for 2006-07. The Australian Southern Rocklobster industry has identified the need to "consider big picture market forces shaping the global food markets'" in the management of profitability of the industry, and the WRLDA has identified the need to develop long term strategic marketing plans.

To catch trends in global lobster markets, Australian lobster industries must have information on their market position relative to each other and other exporting nations. They see the need to increase
understanding by stakeholders of pressures, drivers and economic trends in the global lobster industry.

To achieve this, the unique Global Lobster Market Database (GLMD) developed by WRLDA in 2004 now must be expanded to include the other Australian lobster industries. This will allow them to identify trends in markets enabling development of predictive models by industry, improving the ability of industry to “fish to the market”. Information currently collected does not include all the markets targeted by
Australian lobster producers.

The development of a larger scale, more detailed lobster database, containing information pertinent to all Australian lobster industries, as well exchange rates and market intelligence, will allow the Australian lobster industry to become a significant and more powerful competitor on the world market, addressing needs and wants of consumers rather than being dictated to by commodity markets.

Objectives

1. Extend the WA specific GLMD to other Australian lobster fisheries.
2. Expand the database to include more countries.
3. Development of protocols that assist the marketers of rocklobster to take due regard of their predictive tools.

Rock Lobster Enhancement and Aquaculture Subprogram: the feasibility of translocating rock lobsters in Tasmania for increasing yield

Project number: 2005-217
Project Status:
Completed
Budget expenditure: $19,738.95

Need

Modelling of the Tasmanian lobster resource has indicated that loss of yield through spatial differences in growth of lobsters is greater than 25% of the TACC. Effects of fishing on egg production/recruitment and ecology also appear poorly managed spatially.

Increasing catch targets high priority areas in the strategic plans of each stakeholder. The Tasmanian Government has stated their intent to pursue growth in primary industry as a key strategic area through the “State of Growth” strategy. The project squarely targets all aspects of the University of Tasmania's “EDGE agenda”, particularly through “Engagement” with the community by delivery of a substantial economic benefit. The need for this research has been identified by the commercial and recreational lobster sectors in each strategic plan for crustacean research since the first plan was produced by the CRAG in 1996, specifically under the topics of “stock enhancement” and “translocation”.

Objectives

1. To determine the costs associated with translocation lobsters.
2. To model the economic outcomes of translocation based on available biological data.
3. To combine the cost and economic outcomes into a bio-economic model.
4. To model the economic viability of large scale translocation operations to achieve yield increases.
5. To identify crucial input data that impact on the economic viability of translocation.
6. To identify further data requirements from field experiments.
7. To evaluate cost recovery options for a long term operational system for translocation.

Summary

Translocation involves the shifting of undersize rock lobsters to new areas to increase productivity and/or quality of product. We modelled the translocation of rock lobsters from four original sites to four release sites with a range of growth rates. 

Most model scenarios led to increases in yield at least double the status-quo.  Greatest gain occurred with simulations of the translocation of females from the SW to the NW – in these cases the translocation of 1 tonne led to almost no loss of yield at the origin site but a 1.6 tonne gain at the release site.

Levels of egg production in northern regions are a management issue for the Tasmanian fishery and the model indicated that these would be improved by translocation.  Modelling suggested that both yield and egg production benefits would be greatest when smaller females are translocated and when translocation is integrated with increased regional size limits in the north.  

Economic modelling of scenarios that involved the movement of five tonnes of lobsters by charter indicated that it is possible to generate an additional kilogram of catch for around $2.60. This compares favourably with current lease costs of over $15/kg.  Net state benefit was $160,000 per five tonne trip by a chartered vessel.  The internal rate of return for these operations was around 200%, which constitutes an extremely attractive investment.  

Three possible systems for funding translocation were developed and each involved an allocation of additional quota to fishers.  Translocation appears to offer a feasible option for sustainably and substantially increasing yield by converting low growth, low value lobsters into more productive, higher value lobsters.

Need

Provisions of the Commonwealth Environment and Biodiversity Conservation Act, requiring strategic assessment of fisheries against the principles of ESD including the need to monitor, assess and, if necessary, mitigate the interactions of fisheries with protected species (Fletcher et al. 2002).

In both the SA rock lobster and southern shark fisheries, there are considerable, policy and research requirements relating to fishery interactions with fur seals and sea lions that need to be undertaken within the next 2-3 years in order to fulfil recommendations detailed in recent Bycatch Action Plans and ESD Assessments (detailed in B2).

The National Seal Action Plan requires the estimation of sea lion and fur seal bycatch in gillnet, trawl, trap, dropline and longline fisheries and quantification of interactions with fishing equipment.

Assessment for the need for fishery closures to protect sea lions in the Great Australian Bight Marine Park.

Pinnipeds are listed as protected species under the Commonwealth Environment and Biodiversity Conservation Act, and are known to interact with lobster and gillnet fisheries.

Methods for assessing, monitoring and mitigating the interactions of pinnipeds with lobster and gillnet fisheries are needed urgently.

This need is greatest in South Australia, where:
1. the majority of populations of Australian sea lions occur, and where declining populations have been identified, and where
2. Australia’s largest populations of New Zealand fur seals occur, and where
3. a valuable ($80 M) fishery for southern rock lobster (Jasus edwardsii) is located, and
4. where unquantified interactions between pinnipeds and the lobster and southern shark fisheries are known to occur.

The need to assess the interaction of the Australian sea lion with the South Australian lobster and southern shark fishery is particularly pressing, because the Australian sea lion:
(1) is Australia’s only endemic pinniped;
(2) may be more vulnerable to fishery-induced mortality than other species;
(3) is mainly confined to South Australia, with ~80% of pup production occurring in this state; and
(4) has recently been listed as Threatened (Vulnerable Category)under Commonwealth EPBC Act legislation.

Objectives

1. Synthesise and review the PIRSA and AFMA fishery logbooks for the SA Rock Lobster and Commonwealth shark fisheries for reportings of interactions with seals.
2. Undertake a desktop risk assessment of seal-fishery interactions in the SA Rock lobster and Commonwealth shark fisheries, based on distribution of catch and effort in proximity to seal populations.
3. Review the managment responses related to the extent of protected species interactions with similar species and fisheries on a global scale.
4. Develop a proposal for a comprehensive study to assess the level and nature of interactions between seals and the SA Rock Lobster and Commonwealth shark fisheries, including the development of guidelines for measuring the performance of systems for monitoring, assessing and mitigating interactions between the fisheries and seals.

Summary

This report provides the most comprehensive appraisal of the risk posed by bycatch to subpopulations of Australian sea lions and New Zealand fur seals, by the SA rock lobster and gillnet sector SESSF fisheries. Further it has identified the research required to ensure that SA rock lobster and the gillnet sector SESSF fisheries are managed according to ESD principles, and that interactions with seals are measured, assessed and mitigated. Adoption of these recommendations will lead to the development, and adoption by industry and management of mitigation options to reduce seal bycatch. This will ensure that outstanding ESD recommendations detailed in fishery ESD assessments and the mitigation of the key threatening process identified in the Australian sea lion Draft Recovery Plan are addressed, leading to the recovery and potential future delisting of the species.
