    Abstract

    An aquaculture lease in Flinders Bay (Augusta, south-west Australia) produces adult greenlip abalone (haliotis laevigata) through sea-ranching. in this study, a dispersal model was configured to determine the seasonal variation of the abalone's food source movement (drift-algae) in the Bay. A hydrodynamic model was used to generate wave current fields to force the dispersal model. The results indicated the importance of surface gravity waves in driving circulation in the Bay. Several drift algae movement pathways were found in Flinders Bay and their related incident metocean conditions. Source areas supplying large volumes of drift algae to the aquaculture site were also identified.
