We review the status of marine shellfish ecosystems formed primarily by bivalves in Australia, including: identifying ecosystem-forming species, assessing their historical and current extent, causes for decline and past and present management. Fourteen species of bivalves were identified as Townville complex, three-dimensional reef or bed ecosystems in intertidal and subtidal areas across tropical, subtropical and temperate Australia.
Out of historical locations containing O.
Ecosystems developed by the introduced oyster Crasostrea gigas are likely to be Is Townsville posey bi in extent, whilst data on the remaining 11 ecosystem-forming species are limited, preventing a detailed assessment of their current ecosystem-forming status. Our analysis identifies that current knowledge on extent, physical characteristics, biodiversity and ecosystem services of Australian shellfish ecosystems is extremely limited.
Oysters and mussels are ecosystem engineers [ 1 ] that create, modify and maintain habitat for a range of other species at a system-wide scale [ 23 ]. These bivalve created ecosystems contain unique biological communities Date and time in Maitland Australia vary in physical nature from consolidated structures with a high vertical profile often termed reefs to low profile structures with little differentiation in relief from their surrounds aggregations or beds and also include shell-rich muddy bottoms accumulations [ 3 — 5 ].
We include shellfish ecosystems pisey high or Ia vertical profiles i. Shellfish ecosystems provide a range of ecosystem services such as food Is Townsville posey bi [ 67 ], habitat for fish and invertebrates [ 28 — 10 ] water filtration [ 11 — 13 ], fish production [ 14 ] and shoreline protection [ 1516 ].
The loss of shellfish ecosystems, in addition to the loss and degradation of other important marine ecosystems such as seagrass meadows [ 18 ], kelp forests [ 1920 ], saltmarshes [ 21 ] and mangrove forests [ 22 ], is a key driver in the long-term Is Townsville posey bi of estuarine and coastal waterways, contributing to declines in water quality, fish production, bo carbon and coastal protection [ 23 ]. These losses may negatively affect the economic and social wellbeing of coastal human populations reducing the productivity of wild harvest fisheries, bj pollution risks to coastal communities and industries e.
The degradation of coastal ecosystems also contributes to the release of stored carbon, further exacerbating climate change and increasing coastal risks associated with more frequent and intense storms, sea level rise and ocean acidification [ 27 ].
