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

Seismic surveys undertaken by the petroleum industry and the energy sector in offshore waters use high intensity airguns to characterise seabed petroleum resources and/or potential offshore energy installations. Seismic noise has been shown elsewhere to have adverse effects on marine biota including direct (e.g. injury) or indirect (e.g. behavioural) impacts. A review of relevant literature (including unpublished studies conducted in Victorian waters) is required to fully evaluate potential consequences of expanded seismic surveys. Such a review will provide a more robust basis for decision making by authorised planners consistent with a precautionary approach to development.
