Parks Victoria Technical Series No. 67PPB Sanctuaries Subtidal Reef MonitoringExecutive SummaryShallow reef habitats cover extensive areas along the Victorian coast and are dominated byseaweeds, mobile invertebrates and fishes. These reefs are known for their high biologicalcomplexity, species diversity and productivity. They also have significant economic valuethrough commercial and recreational fishing, diving and other tourism activities. To effectivelymanage and conserve these important and biologically rich habitats, the VictorianGovernment has established a long-term Subtidal Reef Monitoring Program (SRMP). Overtime the SRMP will provide information on the status of Victorian Reef Flora and Fauna anddetermine the nature and magnitude of trends in species populations and species diversitythrough time.The Subtidal Reef Monitoring Program is established throughout Victoria for all relevantmarine protected areas. This report describes the fourth (2009) survey of the Northern PortPhillip Bay sites associated with the Point Cooke, Jawbone and Ricketts Point MarineSanctuaries.The Subtidal Reef Monitoring Program uses standardised underwater visual census methodsto survey algae, macroinvertebrates and fish. For northern Port Phillip Bay, the sites are inshallow water between 2 and 4 m deep. This report aims to:• provide general descriptions of the biological communities and species populations ateach monitoring site in April 2009;• identify any unusual biological phenomena such as interesting communities andspecies;• describe ecologically significant temporal changes in comparison with referenceareas; and• identify any new introduced species, and any trends in existing introduced speciespopulations, at the monitoring locations.The surveys were along a 200 m transect line. Each transect was surveyed for:1. abundance and size structure of large fishes;2. abundance of cryptic fishes and benthic invertebrates;3. percentage cover of macroalgae; and4. density of string kelp species.II
