Role of marine reserves in sustainable management of Australia's ocean estate - review of the Heard Island and McDonald Islands bioregion
The HIMI bioregion supports significant marine conservation values as well as a highly sustainable, and valuable commercial fishing industry. Typically, marine parks/reserve development processes are tasked with developing marine spatial planning arrangements that achieve a balance between preserving conservation values of the area and maintaining/promoting human activities through the principles of Ecologically Sustainable Development (ESD). However, key uncertainties remain regarding the policy priorities and how the final design of marine parks are objectively determined.
This project will provide an independent assessment of the framework used for original design of the HIMI Marine Reserve in 2002, the review in 2014, and the current review to provide recommendations for future development. The project will also explore how/if the policy objectives have been achieved since inception . Furthermore, this project will explore the potential of a quantitative risk-based approach to provide for minimising the uncertainties in the Marine Protected Area (MPA) development processes and deliver an objective framework.
In addition, the project will explore the current HIMI marine reserve framework, the associated commercial fishing industry arrangements and how they intersect with regard to:
Regulation
• Regulatory processes to minimise impacts of commercial fishing
• Legislative framework currently in place for Ecological Risk Assessment/ESD, Ecosystem-Based Fisheries Management, bycatch policy strategic research plans
• Marine Protected Areas review processes
• Statutory Fishing Rights (SFRs)
Economic impacts
• Commercial fishing viability
• Statutory fishing rights
• Permitted fishing gear types – (e.g. potential removal of MSC certified trawl fisheries with additional implications on research activity)
Biological impacts
• Impact on juvenile toothfish index of abundance and icefish estimates – accuracy of tracking stock will be significantly reduced if ability to trawl is removed (i.e. random stratified trawl survey impacted)
• Stock assessment model ability to consider toothfish population structure if longline fishery further constrained
• Climate change and effects of population shift
• Increasing policy position of MPAs as fisheries management tools
• Increased localised depletion and constrained ability to distribute commercial fishing effort
Social Impacts
• Market access
• Community sentiment

Determination of the impacts of direct harvest of coral species in northern Australia
Australia’s aquarium fisheries are high value (GVP >$20 million), small scale fisheries that rely on exporting CITES listed corals for profitability and viability. The Australian government requires fisheries collecting and exporting these species to demonstrate that their harvest is sustainable under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) in order to meet Australia's obligations under CITES.
In the absence of empirical evidence, precautionary harvest limits are set on all coral species, and monitored and reported by NT Fisheries to the Commonwealth Department of Environment and Energy (DoEE), to fulfil EPBC requirements. Increased global demand for valuable coral species presents an opportunity for licenced fishers to develop new and existing international markets. However, in order to increase harvest limits, evidence is required to reinforce that the harvest and subsequent export will not have a detrimental effect on the population status of the species (CITES non-detriment finding). Any supporting non-detriment finding must be corroborated with new empirical evidence on the impacts of harvesting corals.
The FRDC project ‘Establishing baselines and assessing vulnerability of commercially harvested corals across northern Australia’ (FRDC 2014-029) (currently underway) attempts to address some of these issues including taxonomy, abundance and distribution of key coral species but fails to address the long-standing concern of the impacts of coral harvesting. Understanding and quantifying the impacts of harvesting coral has the potential for providing the greatest benefit to industry. The specific need is to investigate the extent of recovery (or not) of key species of Scleractinian (hard) corals harvested at the level of individual colonies over an appropriate temporal scale.
Members of the A12 Aquarium display fishery are supportive of this project and will be actively involved in assisting with data collection. This project directly addresses the NT Research Advisory Committee priority ‘Impact of harvesting key species of Scleractinian (hard) corals in the Northern Territory’.
