“…Abundance concentrations were dense on substrata identified as ridges or valleys (rugose relief), with comparably low densities of blacklip abalone inhabiting relatively flat substrata. It defines the physical structure of the reef and often correlates positively with the abundance and biomass of reef fish (Pittman et al 2007;Walker et al 2009;Zeeman et al 2012). Reef complexity is among the general factors that determine the area of available cryptic habitat for benthic species (Kuffner et al 2007).…”

Infectious pathogens figure prominently among those factors threatening marine wildlife. Mass mortality events caused by pathogens can fundamentally alter the structure of wild fish stocks and depress recruitment rates and yield. In the most severe instances, this can precipitate stock collapses resulting in dramatic economic losses to once valuable commercial fisheries. An outbreak of a herpes‐like virus among commercially fished abalone populations in the south‐west fishery of Victoria, Australia, during 2006–2007, has been associated with high mortality rates among all cohorts. Long‐term records from fishery‐independent surveys of blacklip abalone Haliotis rubra (Leach) enabled abundance from pre‐ and post‐viral periods to be analysed to estimate stock density and biomass. The spatial distribution of abundance in relation to physical habitat variables derived from high‐resolution bathymetric LiDAR data was investigated. Significant differences were observed in both measures between pre‐ and post‐viral periods. Although there was some limited evidence of gradual stock improvement in recent years, disease‐affected reefs have remained below productivity rates prior to the disease outbreak suggesting a reduction in larval availability or settlement success. This was corroborated by trends in sublegal sized blacklip abalone abundance that has yet to show substantial recovery post‐disease. Abundance data were modelled as a function of habitat variables using a generalised additive model (GAM) and indicated that high abundance was associated with complex reef structures of coastal waters (<15 m). This study highlights the importance of long‐term surveys to understand abalone recovery following mass mortality and the links between stock abundance and seafloor variability.

“…Kelp forests along the west and south-west coasts are characterised by different benthic communities, with the distinction between the two coasts occurring at Cape Point (Field et al 1980;Anderson et al 1997;Leliaert et al 2000). The West Coast rock lobster Jasus lalandii, as well as mussel species, Choromytilus meridionalis, Semimytilus algosus and Aulacomya atra, are characteristic of west coast kelp forest communities (Field et al 1980;Branch & Griffiths 1988;Van Erkom Schurink 1990;Skein et al 2018), where the substratum in the shallows is often dominated by dense red algae (Anderson et al 1997;Zeeman et al 2013).…”
