Factors Limiting the Resilience and Recovery of Fishing Abalone Populations Project Number - 2005/029 (adopted project from the FRDC) Start Date - 1st July 2005 End Date - 30th June 2008 Principal Investigator - Dr Craig Mundy Research Provider - University of Tasmania CRC Research End User - Abalone Council of Australia
About the Project As abalone management is becoming increasingly more focused on varying finer spatial scales, the effects of localised depletion, varying growth rates between reef systems and the accuracy of mimimum legal lengths are increasing in importance. More recently, the impacts associated with the abalone virus on wild abalone populations has put further pressure on the management of stocks and the need for stock rebuilding strategies. This project has successfully translocated abalone between sites in Tasmania and has also begun undertaking larval dispersion analysis. Translocation, if feasible may provide one mechanism to enhance previously depleted reef. The use of hatchery produced larvae as a re-seeding technology has previously been shown to be problematic and dependent on an understanding of the habitat type, existing abalone density, environmental conditions and the deployment methodology. The project has commenced assessment of larvae as a possible cheaper option. Larval technology offers a method that could be used for large scale dispersion. Project Objectives 1. To identify key ecological processes that limit standard recovery. 2. To quantify the scale of spillover benefit from translocated populations. 3. Cost benefit analysis of rehabilitated habitat. __________________________________________________

Scope and Economic Analysis of Options for a Nationally Unified Breeding Program that Provides Significant Economic Benefit to the Australian Abalone Aquaculture Industry Project Number - 2008/722 Start Date - 1st March 2008 End Date - 31st August 2008 Principal Investigator - Dr Nick Robinson Research Provider - SA Research and Development Institute CRC Research End User - Australian Abalone Growers Assoc
About the Project The major limitation to the economic profitability and growth of the industry has been the long production time of abalone to reach market size. This project will assist in the development of a coordinated national breeding program for cultured Australian abalone. The industry sees selective breeding as offering the greatest return on investment. Project Objectives 1. To model the Tasmanian GW program(s) and alternative mainland strategies and determine the optimal strategy for a unified coordinated program. 2. To identify the areas of collaboration for adding value to each program and the standardisation of procedures needed to ensure collaboration is achieved. 3. To identify key researchable constraints to the implementation of the breeding program, prioritise the research objectives and identify funding options. 4. The cooperative breeding program that develops will aim to achieve the objectives of the Australian Abalone Growers Association. _____________________________________________________
