What Is a Fish Kill, and Why Are They Happening More Often?

  • South Australia has experienced a prolonged toxic algal bloom since March 2024, severely impacting marine life and coastal industries.
  • The bloom arose from a combination of nutrient influx from 2023 River Murray floods, a marine heatwave beginning September 2024, and calm water conditions, all linked to climate change.
  • More than 200 species, including fish, sharks, and crustaceans, have died, with the bloom reaching over 4400 square kilometers and spreading across Gulf St Vincent and multiple peninsulas.
  • Fishing sales dropped 70%, affecting livelihoods, while experts urge increased water monitoring and community-driven restoration through oyster reefs and seagrass beds.
  • Despite calls to declare a national disaster, the federal government resists, prompting state officials and fishers like Rod Ness to press for greater support amid ongoing ecological and economic damage.
