At each site, measurements and observations were performed to characterise key indicators of benthic effects including sediment grain size, sediment organic content, sediment smell and colour, depth of sediment, redox layer, infaunal community composition, epifaunal community composition, and shell drop. Results showed no evidence that the mussel farming activity had caused significant adverse impacts to the benthic habitat or communities beyond and beneath farm boundaries. The aim was to measure a suite of key seabed characteristics to detect any significant changes to seabed conditions resulting from the marine farming activity.
