2008/904 Benefit-cost analysis of marker assisted selection in Australian aquaculture species

 By Dr Nick Robinson

This project relates to the research strategies developed by the CRC from projects that have scoped selective breeding for abalone, Yellowtail Kingfish and Barramundi. There is potential that genetic marker assisted selection (MAS) techniques could greatly speed the genetic progress in these selective breeding programs and provide faster access and more benefit than conventional selective breeding techniques. The analysis in this report addresses some of the questions raised by the use of MAS techniques in selective breeding programs for the seafood industries participating in the Australian Seafood CRC. This report

• Draws together an overview of trait priorities identified by seafood industries participating in the Australian Seafood CRC
• Explores which factors are likely to affect the success of the development and application of marker assisted selection
• Estimates some of the costs and likely benefits involved in developing and from applying marker assisted selection

The report identified:

• Basic resources that are available or needed for each species before research can be carried out to find markers or to apply these technologies.
• Likely cost-benefits for the development and application of these technologies and traits that would be best targeted using the technologies.
• When research should be undertaken and developments that might trigger research in this area for each species and;
• The potential impact of the application of these technologies on other industries.
