Abstract

Fisheries Sciences aquaculture genetic improvement
The lack of genetically improved strains capable of producing high quality seed is consistently identified as the most widespread and persistent technical obstacle to the sustainable development of aquaculture both nationally and internationally. We, at USC, have been focussing on the development and application of new genetic and reproductive technologies to develop improved strains and enhance quality seed production for national Australian industries and to support regional efforts to meet this need. Here we provide examples of the technologies that we have recently developed, namely DNA markers for parentage assignment, desired gain selection index theory and modern genetic evaluation and mate allocation systems, which have been applied to improve quality and productivity of yellowtail kingfish and banana prawn. The 'genetic package' developed is to be implemented in selective breeding programs for Oysters and Giant groupers as well as other new emerging species in Australia and overseas, starting with DNA investigations to verify the integrity of the base populations in terms of inbreeding levels, genetic variability and species purity. In this presentation, we also discuss potential future research programs being developed in collaboration with neighbouring countries in the region and with the industry partners in Australia.
