FRDC-DCCEE: preparing fisheries for climate change: identifying adaptation options for four key fisheries in South Eastern Australia

Over the next century, the marine ecosystems of south-eastern Australia are expected to exhibit some of the largest climate-driven changes in the Southern Hemisphere. The effects of these changes on communities and businesses will depend, in part, on how well fishing industries and resource managers...

Need

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.

Objectives

1. Identify the life history stages, habitats and aquaculture systems of key species that may be impacted by climate change
2. Identify the physical and chemical parameters that may determine the potential impacts of climate change on key species
3. Conduct a preliminary risk assessment of each key species to the potential impacts of climate change
4. Highlight what additional information on the tolerances and sensitivities will be needed to develop bioclimatic envelope models for key species

Understanding recruitment collapse of juvenile abalone in the Eastern Zone Abalone fishery – development of pre-recruitment monitoring, simulation of recruitment variation and predicting the impact of climate variation

Over the past three decades the Tasmanian Eastern Zone Abalone Fishery has experienced several fluctuations in catch and catch rates of Blacklip Abalone as well as environmental perturbations, which may be affecting productivity. The capacity to measure inter-annual variation in Blacklip Abalone...

Rebuilding Ecosystem Resilience: assessment of management options to minimise formation of ‘barrens’ habitat by the long-spined sea urchin (Centrostephanus rodgersii) in Tasmania

By overgrazing seaweeds and sessile invertebrates, essentially back to bare rock, the advent of the long‐spined sea urchin Centrostephanus rodgersii in eastern Tasmanian waters poses a significant threat to the integrity, productivity and biodiversity of shallow (<40 m) rocky reef systems and the...
