Funded Activity Summary

Several initiatives by the Australian Seafood CRC's Future Harvest theme involve some form of stocking or enhancement of fisheries. In WA, populations of Roe's Abalone are currently being restocked after a catastrophic mortality event, while stock enhancement of Greenlip Abalone is also occurring. The CRC is also supporting translocation of Southern Rocklobster and ranching of Sea Cucumbers. In all such cases there is a need to understand the population genetic dynamics of stocked populations and the extent of genetic interactions of stocked with wild populations (Flinders has been conducting his research for sea cucumbers using the traditional microsatellite marker approach in 2008/733). Important considerations are the genetic health of individuals used as breeders, genetic structuring of source populations, effective population size, effects on inbreeding or loss of genetic diversity, recruitment and geographic spread. Molecular markers can be used to investigate these effects and guide the stocking. Genomic technologies such as GBS are rapidly developing and becoming less expensive and more useful to apply than traditional genetic approaches. These new genomic techniques that directly genotype individuals using sequence information are extremely promising as they eliminate the need for species specific marker development and could provide an efficient and comprehensive means of studying genomes at an individual and population level. Importantly, contrary to traditional genetic methods such as microsatellite surveys, new genomic techniques such as GBS might provide ways of disclosing functional genetic variation (variation that is ecologically relevant and related to the fitness of the individual) or facilitating genomic selection. Once GBS data is mapped to areas of the genome with known function, marker assisted selection for traits of importance to aquaculture becomes possible.
Here we propose engaging a post-doc that will specialise in this area and assist projects with Flinders involvement on Roe's and Greenlip Abalone in Western Australia.
