In short:
A microalgae bloom is the likely cause of dead marine life reported from Waitpinga to Basham Beach in the Fleurieu Peninsula, the EPA says.

The Department of Primary Industries and Regions (PIRSA) is investigating the fish deaths.

What’s next?
Initial results from water testing would be available in about a week.

In short:
A mysterious foam has washed up on a beach on SA’s Fleurieu Peninsula.

Surfers who visited over the weekend have reported coughing, sore throats and blurred vision.

What’s next?
SA’s primary industries department is investigating reports of a “fish mortality event” and two beaches have been closed.

Tasmania is tackling the invasive Longspined Sea Urchin by overfishing it, successfully halving its population and protecting kelp forests. A new study shows this innovative, government-subsidised approach is both ecologically effective and economically sustainable, offering a global model for managing climate-driven marine pests.

One of Tasmania’s largest wild fisheries species is being overfished, but scientists say it’s a good thing. Why they say this practice could save species across the globe.

---

This study explores how government incentives have created a commercial fishery to deliberately overfish an invasive urchin species, protecting kelp ecosystems. The approach balances exploitation and conservation, offering a novel model for managing climate-driven species expansions.

Australia’s orange roughy fishery has received MSC certification despite strong opposition from environmental groups, who argue the species is still threatened. Fisheries representatives defend the move as a sign of successful stock recovery and compliance with the MSC’s updated, rigorous sustainability standards.

From April 2023 to March 2024, global ocean surface temperatures remained at record highs, surpassing the previous 2015–2016 record by an average of 0.25 °C — an event estimated to occur only once every 512 years under current warming trends. Climate models confirm such extreme temperature jumps are possible due to human-driven global warming and suggest ocean temperatures will likely return to the long-term warming trend following this exceptional event.

Researchers in Tasmania are turning waste from invasive sea urchins—harvested to protect reefs—into a potential fertiliser for farms. Trials show the urchin waste raises soil pH and provides nutrients, offering a sustainable solution that benefits both agriculture and marine ecosystems.
