Increasing evidence suggests that the waves produced by even low-wash vessels can have a sizeable impact on infaunal assemblages in otherwise sheltered estuaries. Although this impact is widely regarded to be a consequence of wash coarsening sediment grain-size, it may be due to a number of alternative mechanisms which include enhanced turbidity, decreased larval supply, changed resource availability and/or erosion of animals from the sediment. To increase understanding of impacts resulting from boat-wash, this study tested alternate mechanisms by which intertidal infauna along the Parramatta River, Sydney, Australia are impacted by wash from local ferries.
