Need

The Strategic Plan Summary (FRDC 2002/313) reports as follows:
For all its economic promise the industry faces some challenges that constrain growth and profitability:
• Lack of appropriate peak body structure and supply chain fragmentation
• Limited enterprise commitment to joint industry development
• Complacency in dealing with market issues – predominant wild caught focus
• Limited sectoral or peak body strategic planning
• Policy dominated by resource managers and technologists rather than those with commercial and market experience.

The industry structure comprises around 700 small owner operator businesses with little or no capacity to coordinate investment in and manage industry development. Recovering lost industry value and delivering future growth is contingent upon coordinated investment in industry development at the whole of industry level.

SRL is now established and positioned to implement the strategic plan, and integration of R&D work across stakeholders, States, Australia and New Zealand, rock lobster subprograms, researchers and other related disciplines is now feasible under the leadership of SRL.

Two distinct needs are involved in any consideration of better national R&D co-ordination for the southern rock lobster sector:

1. The strategic issues of R&D prioritization, funding and the linkages to (and support for) both industry development plans and Government objectives of industry development.

2. The operational issues of facilitating effective communication and coordination at all levels (industry/researchers, among researchers, among industry, FRDC/researchers etc).

Objectives

1. To coordinate the investment by FRDC and SRL to achieve the planned outcomes detailed in the SRL Strategic Plan
2. Provide a communication and extension service that complements the individual projects to facilitate adoption of outputs
3. To provide reports to FRDC and SRL Ltd that demonstrate effective management of the individual projects, and contribute to good governance

Rock Lobster Enhancement and Aquaculture Subprogram: the nutrition of juvenile and adult lobsters to optimise survival, growth and condition

Research in FRDC RLEAS 98/303 established that tropical (Panulirus ornatus), southern (Jasus edwardsii) and western (Panulirus cygnus) rock lobsters readily consumed formulated pelleted dry feeds and exhibited a dose dependent growth response to dietary protein concentration. The derived optimum...

Seafood CRC: visiting Expert: Dr Standish Allen - enhancement of tetraploid and triploid production in the Australian Pacific Oyster industry

The overall goal for shellfish culture limited (SCL) is to make tetraploid technology work as effectively as anywhere in the world. In many ways, SCL is ahead of the game, with dedicated facilities and technicians to pursue this goal. There is currently only a hand full of commercial operations...

Evaluation of practical technologies for Perfluoroalkyl (PFA) remediation in marine fish hatcheries

Per- and poly-fluoroalkly substances (PFASs) are now emerging as pollutants with potentially catastrophic impact on aquaculture facilities. Two key research institutes, Port Stephens Fisheries Institute (PSFI) in NSW and Australian Centre for Applied Aquaculture Research (ACAAR) in Western Australia...

Southern Bluefin Tuna Aquaculture Subprogram Project 1: implementation and coordination of research experiments conducted with farmed southern bluefin tuna to assess manufactured diets, feeding regimes and harvesting techniques

The Southern Bluefin Tuna (SBT), Thunnus maccoyii, Aquaculture Industry has undergone rapid expansion since it commenced in 1990. In 2002/03 the industry was Australia’s third largest export fishing industry (ABARE, 2002) with most of its value coming from aquaculture. In this year the...

Need

SBT:
There is a need to better identify the relationship between hormonal treatment and spawning performance as this will determine the hormonal manipulation strategy. There is also a need to better
understand factors associated with broodstock mortality, as currently 30% of the broodstock die every year and thus need to be replaced.

We need to develop methods of ensuring that all females participate in spawning every year and how to extend the spawning cycle to have eggs for four months of the year.

There is a need to advance the initiation of spawning to October (from the current norm of February) so that the fingerlings are ready to be transferred to sea cages sufficiently early in the calendar year for optimal seawater temperatures.
SBT broodstock reach spawning age at about 12 years of age. There is therefore a need to examine alternative technologies and approaches to obtain tuna seed from younger fish.

YTK:
This genetic management and selection project is needed to maintain a commercial advantage in a highly competitive market and as a management tool to prevent inbreeding.

It is difficult to source wild YTK broodstock, and the current stock are getting older and larger. There is a need to source new broodstock, and it will be advantageous to use selected F1, provided they can be genetically managed.

Objectives

1. Extend the spawning season of captive SBT from 2 months to 4 months
2. Bring forward the spawning season of SBT to achieve initiation of spawning in September/ October rather than the current February/April.
3. Monitor spawning dynamics of individual SBT broodstock
4. Develop a tool for sexing of SBT broodstock to ensure sufficient number of females are available
5. Maximise the number of SBT females that participate in the spawning and monitor egg quality in relation to hormonal spawning induction.
6. Aim to obtain natural spawning in SBT (i.e without the use of hormonal implants)
7. Investigate alternative spawning induction protocols with less physical impact on the treated fish
8. Determine the suitability of YTK as a surrogate for SBT and explore alternatives if needed
9. To develop a YTK genetic management and genetic breeding program for CST to control and minimise inbreeding (e.g. there will be no inbreeding depression for the commercially produced fish during the life of the project or in perpetuity)
10. To maximize the speed of commercial return by culling poor performing broodstock or by identifying preferred broodstock and using existing and new F1 stock
