                  9. Oyster gardeners care for        Oyster gardeners are responsible for:
                  oysters                                · Monitoring of gardens every couple of days and shaking
                                                              the baskets to release pseudo-faeces.
                                                         · Inspecting and hosing down the baskets at least one per
                                                              month (more often in areas where high algal growth or
                                                              sedimentation occurs)
                                                         · Affixing repairs to the mooring lines or baskets, as
                                                              required. Oyster gardeners may seek assistance from the
                                                              project team.

                                                      Oyster gardeners are encouraged to record observations (rate of
                                                      algae growth, interesting species, any wear and tear of gardens).

                                                      The project team will inspect oyster baskets periodically and take
                                                      measurements. Oyster gardeners may assist.
                  10. Records                         Project team will keep accurate records of oyster gardeners,
                                                      contacts, number of baskets, maintenance activities undertaken
                                                      and eventual fate of baskets.
                  11. Decommissioning                 Oyster gardens remain in commission for 6 to 12 months.
                                                      Oyster gardens are then inspected by the project team and the
                                                      oysters and cultch released onto the oyster restoration sites by
                                                      TNC as per the project specifications.
                                                      After the oysters and cult are released, the baskets will be
                                                      collected by TNC/NICA, dried and repaired for future use,
                                                      returned to Bribie Island or disposed of at the Doonan Solid
                                                      Waste Facility.
                  12. Reporting                       Project partner, NICA, is required every 6 months to report to
                                                      TNC on project progress.
                                                      TNC reports twice per year on project progress to agencies.
                                                      TNC remains in close contact with NICA throughout project
                                                      implementation and assists technically with project
                                                      implementation.


                 The oyster gardening techniques applied in Noosa are adapted from the Bribie Island oyster gardening
                 project led by Dr Ben Diggles. Dr Diggles has been consulted during the formation of this project. Dr
                 Diggles has also provided the Noosa project with 70 pathogen free oyster baskets for use in the project.
                 The project also draws on TNC’s success with the mussel gardening in Western Australia
                 (https://www.natureaustralia.org.au/newsroom/mandurah-mussel-gardens/) and with oyster
                 gardening caried out by TNC and its partners in the USA.

                 Shellfish gardening is practiced worldwide, and the methodologies are simple, safe and prevent the
                 spread of disease through simple design and tried and tested methodologies and sound record
                 keeping12. An example of a rock oyster garden that will be used in Noosa is presented in Figure 5.5.
