South Australia’s seafood sector is facing the potential long-lasting effects of a toxic algal bloom, which recent studies suggest could persist for at least another year. Environment Minister Susan Close announced that this ecological challenge is expected to linger, with adverse impacts likely to recur periodically.
She emphasised the need for communities to understand that the bloom is not a short-term issue. As water temperatures fall, the algae will settle on the seabed, remaining dormant until conditions allow for a resurgence. Close attributed the severity of the bloom to climate change, highlighting its significant implications for the seafood industry.
Local operators, like Glenn Hill of Coorong Wild Seafood, expressed concerns about potential job losses, corroborating reports of existing closures in certain oyster farms and fisheries due to the algal bloom. Hill warned that if the situation deteriorates further, it might lead to a severe reduction in seafood availability, leaving fisheries vulnerable with potentially no catch left.
Despite these alarming developments, the government is working to reassure the public about the safety of purchasing seafood from South Australia. Minister Close stated that consumers can feel confident in the safety of these products, amidst growing public worry.
Adding to the environmental impact, there have been concerning sightings of marine life, such as a large stingray and a great white shark washed ashore, raising further alarm over the algal bloom’s effects. Authorities are keeping a close watch on the situation, particularly along metropolitan beaches, with fears that the bloom might spread to areas like the Port River and West Lakes.
Close highlighted the necessity of being prepared for ongoing challenges posed by this bloom, indicating that proactive measures are essential for both the environment and the local economy.
