Australian blue mussels (Mytilus spp.) are an increasingly important sustainable product of the aquaculture industry. Although for commercial fisheries, may have adverse environmental and ecological impacts. This study assessed impact standard hatchery-imposed selection practices on genetic diversity farmed mussels. Using microsatellite markers, relatedness structure analyses showed that hatchery-reared larvae high levels without a significant decline as they move through hatchery rearing process. Selection and/or drift does appear to be operating during process, however, evidenced by increase in among over time. Significant shifts allele frequency well clusters provides further evidence is acting due practice applied at hatchery. Comparison level differentiation adults from wild populations provided no lower diversity, or genetically swamping local natural populations. The data suggest careful design implementation mussel breeding programs can maintain not lead surrounding area.
