A toxic algal bloom affecting South Australia has led to the deaths of over 200 marine species, including sharks, leafy sea dragons, and octopuses. The bloom, primarily driven by marine heatwaves, has negatively impacted fish populations of all ages and significantly threatens local fisheries. While the algae poses no direct threat to humans, it can cause skin irritations and respiratory symptoms. The presence of the algae has raised concerns regarding long-term ecological and economic effects, particularly on fisheries and local marine habitats.
Brad Martin, the OzFish South Australian project manager, described the toxic algae bloom as a "blanket" that smothered marine life, suffocating fish and causing unusual behavior.
The algal bloom, driven by a marine heatwave and calm conditions, has resulted in the death of over 200 species, highlighting the critical impact on South Australiaâs marine ecosystem.
Despite not being toxic to humans, the algae can lead to skin irritations, respiratory issues, and has caused mass mortalities in marine life, raising concerns for fisheries.
With water temperatures 2.5C above normal, this harmful bloom has become a significant ecological threat, affecting fish from all stages of life and endangering marine habitats.
