Climate change is manifesting in marine environments. Additional to climate variability there is documented shifts in ocean currents - temperature, behaviour and spatial impact. Biotic indications eg species changes in abundance and range suggest impacts are at a level greater than for terrestrial ecosystems and uses. Coupled with this is the common property nature of fisheries resources. Management imperatives are already upon Government and all key sectors - conservation, commercial and recreational fishery management and aquaculture.

The first two challenges are to -
a) smartly adapt to biotic changes and variations in abundance
b) foster a more flexible and responsive approach to marine management.

Climate change is a political issue - the public policy issue that has been most incompetently dealt with by Australia's political leaders. Community understanding of the complexities of climate change and how Australia should respond is varied with multiple areas for confusion and misunderstanding. Additionally, those promoting a mitigation response have been alarmist in their predictions - well beyond the science evidence.
With this confusion as to the implications of climate change and options for adaptation and mitigation strategies, informed debate is extremely difficult. The recreational fishing sector is no different to the wider community.

Given the economic and social importance of recreational fishing in Australia, there is a national need and strong regional demand for strategies and adaptation activities and management systems that respond wisely to climate change.

The second two challenges are to:
c) ensure accurate information on climate change information is available and is placed in context with other aspects such as habitat loss and water quality
d) foster knowledge and adaptation strategies from within the recreational fishing sector so that the sector can play its role in advocacy and public policy development.

Climate change is expected to alter physical and chemical oceanographic conditions and processes around Australia, yet the influence this could have on the distributions of various marine species is still relatively unknown. The marine waters of South Eastern Australia are expected to be significantly affected by climate change, experiencing the greatest climate-driven changes in the southern hemisphere over the next century. The impacts and opportunities that will result from these changes will depend, in part, on how well the fisheries and aquaculture sectors and their managers respond to these challenges. A sound risk-based approach to informing both management arrangements and decisions by the sectors will be critical for optimizing outcomes. It is essential that the potential impacts of climate change on key resources are assessed and effectively communicated to support the development of policies that allow industry to minimize adverse effects by optimizing adaptation responses (e.g. by providing flexible management arrangements) and seizing opportunities as they arise (e.g. for species where productivity increases).

This project has been identified as a clear and immediate need through the SEAP Plan (draft) and also establishes a platform of baseline information from which we can start to address several key priority areas identified in the Draft Marine National Adaptation Research Plan (NARP). Priorities identified in the draft NARP include 1/ Which farmed species in which locations are most likely to be impacted as a result of climate change?, and for fisheries 2/ Which fishery stocks, in which locations, are most likely to change as a result of climate change? What will those changes be (e.g., in distribution, productivity) and when are they likely to appear under alternative climate change scenarios? Clearly, comprehensive and synthesised information on the sensitivities and tolerances of key species are the first steps required to address these priorities.
