The South Australian Government are providing a weekly newsletter with updates for what is happening along the South Australian coastline.
Their newsletter aims to bring you clear facts, safety advice, and timely updates so you can stay informed. Share it with friends and family to help everyone feel confident about visiting the beach and enjoying local seafood.
South Australia’s toxic Karenia mikimotoi algal bloom has killed vast amounts of marine life, fuelled by unusually warm, calm seas and lingering nutrients from floods and upwelling. Climate change is expected to make such harmful blooms more frequent and severe, highlighting the need for climate action and better nutrient management.
Last week, the Sea Change Australia team held our first case study workshops in Albany and Fremantle, WA, bringing together fishers, managers, and researchers to discuss climate change impacts and adaptation for the south-west’s nearshore and estuarine fisheries. Supported by DPIRD and the FRDC, the workshops marked an important step in collaborative planning for a changing climate.
In short:
Support measures for SA’s recreational fishing sector as it battles the algal bloom include plans for an artificial reef and an expansion of fishing in reservoirs.
A $200,000 grant will go to RecFish SA to bolster community fishing participation.
What’s next?
RecFish SA has backed the reservoir plan but says it will require feedback from SA Water and SA Health.
Ocean heatwaves are intensifying, with all Australian waters warmer in winter 2025 and heat-linked events like algal blooms emerging. Professor Matthew England warns that a major Atlantic current (AMOC), which helps regulate climate and support marine life, is slowing with global consequences.
Editor’s summary
Global warming is causing substantial, rapid changes in our oceans. Attempts to adapt to these changes have already involved a host of marine-climate interventions, but to what effect? Morrison et al. reviewed the evidence and concluded that the marine governance systems meant to ensure that climate goals remain achievable and that societal and ecosystem risks are minimized have failed to keep pace with mitigation efforts. Intervention-specific principles need to be embedded within governance at all levels to avoid the worst risks associated with deploying new marine-climate interventions at scale. —Jesse Smith
The Albanese Government is supporting the rollout of a new long-range marine heatwave forecasting system, developed by the Bureau of Meteorology and CSIRO. Launching publicly in the 2025/26 summer, the outlooks will predict ocean temperature extremes up to three months in advance to help protect marine ecosystems and support fisheries, aquaculture, and climate resilience planning.
Climate change is taking a toll on scientists’ mental health, with many experiencing distress from witnessing environmental decline. Marine ecologist Gretta Pecl says this emotional response is rational and promotes “active hope” as a way to stay engaged. She also leads initiatives to support researchers coping with climate grief.
ABC North and West SA: Race to understand Giant Australian cuttlefish behaviour as algal bloom looms
In short:
Marine scientists and wildlife authorities are undecided about how to mitigate the impact of the algal bloom on cuttlefish eggs in the Upper Spencer Gulf.
Temporarily moving the hatchlings is one option, but could lead to unintended consequences.
What next?
Ecologists say the ideal time to relocate the cuttlefish eggs would be in the next few weeks.
