The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "State and Trend of inner shelf (0-30 m) – reef fish species". <br /> ***A PDF of the full Expert Assessment, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "EXPERT ASSESSMENT 2021 - Inner shelf (0-30 m) – reef fish species"***<br /> <br /> ----------------------------------------<br /> <br /> DESCRIPTION OF SPECIES/HABITAT/COMMUNITY/PROCESS FOR EXPERT ASSESSMENT<br /> Bony and cartilaginous fish assemblages found on coastal rocky and coral reefs &lt;30 m depth around the Australian continent, including both exploited and unexploited species.<br /> <br /> DATA STREAM(S) USED IN EXPERT ASSESSMENT<br /> Underwater visual census data from Reef Life Survey, the Australian Institute of Marine Science, and the Australian Temperate Reef Collaboration. National synoptic change (mean 2011-2015 period vs mean 2016-2020 period) and 18 long-term monitoring locations spread nationally.
