This spatial boundary supports the marine bioregional boundaries as described in the State of the Fisheries Reports, that follows those of the Interim Marine and Coastal Regionalisation for Australia report (IMCRA Technical Group) except for the inclusion of the Gascoyne coast as a separate region.

This data set contains the current Instrument of Exemption (IOE) boundaries for WA fisheries. Each feature relates to the management boundary of a specific type of fish / fishery / area or activity. These boundaries comprise one component of all fisheries related boundaries prescribed by WA fisheries legislation. The full list of WA fisheries boundaries as documented in the annual ‘Status Reports of the Fisheries and Aquatic Resources’ is comprised of 6 different categories that have been grouped together as the Fisheries Guide. Fisheries Guide – CEO Notices and Determinations Fisheries Guide – Consolidated Management Plans Fisheries Guide – Consolidated Notices and Orders Fisheries Guide – Instrument of Exemption Fisheries Guide – Licence Conditions Fisheries Guide – Open Access When searching for particular information in relation to a type of fish / a fishery / an area or activity, then it is important that you refer to all of the above Fisheries Guide categories, as looking in just one category alone may not return all of the relevant boundaries.

Oyster Harbour was surveyed in March 2019 and January 2021. Seagrass species distribution (Posidonia australis and Posidonia sinuousa) and cover (as percentage cover classes: 0, <15%, 15-45%, 45-75%, >75%) was recorded across 208-216 observations points across the estuary. The type of meadow (continuous or patchy), epiphytic cover on seagrass (as none, very low, low, medium, high or very high), and macroalgae cover (as percentage cover in categories: 0, <15%, 15-45%, 45-75%, >75%) were recorded at each site. At approximately a third of the sites, physical water profiles, secchi depth and euphotic depth were recorded. The datasets making up the seagrass survey data are: Oyster_Seagrass - point dataset Oyster_Seagrass_Extent - polygon showing presence/absence Oyster_Seagrass_Cover - polygon showing % cover Layers: Oyster_Seagrass_Mar_2019 - Oyster_seagrass points where Year = '2019' Oyster_Seagrass_Jan_2021 - Oyster_seagrass points where Year = '2021' Oyster_Seagrass_Extent_Mar_2019 - Oyster_seagrass_Extent where Year = '2019' OR PERCCOVER = 'Licensed aquacture site - DPIRD - not surveyed' Oyster_Seagrass_Extent_Jan_2021 - Oyster_seagrass_Extent where Year = '2021' OR PERCCOVER = 'Licensed aquacture site - DPIRD - not surveyed' Oyster_Seagrass_Cover_Mar_2019 - Oyster_seagrass_cover points where Year = '2019' OR PERCCOVER = 'Licensed aquacture site - DPIRD - not surveyed' Oyster_Seagrass_Cover_Jan_2021 - Oyster_seagrass_cover points where Year = '2021' OR PERCCOVER = 'Licensed aquacture site - DPIRD - not surveyed'
