South Australia's government has declared the toxic algal bloom that ravaged its coastline for more than a year "effectively clear" — but along the gulfs, the fishing closures, quiet tackle tills and missing squid tell a very different story.
Premier Peter Malinauskas based the declaration on testing that found "effectively zero Karenia throughout the state's coastline." The turnaround is stark: he said 9,400 kilograms of dead sea life had washed up on South Australian beaches every week in December 2025, a figure that has since fallen to less than 50 kilograms a week. Routine testing for the Karenia bloom will now revert to monthly in areas without active blooms.
Yet the same announcement tightened the screws on anglers. Restrictions on Southern calamari were extended across Gulf St Vincent and the Spencer Gulf, a recreational and charter-boat closure was imposed in the gulf, and a spawning closure for King George whiting runs until 31 July. Existing snapper closures were extended a further 12 months.
For the people who sell the gear and chase the fish, the "recovery" is still theoretical. Alicia Bolitho, who owns Tackle World stores in Port Lincoln and Port Augusta, normally banks a winter profit selling squid jigs. Not this year.
"When the bloom arrived, the squid just absolutely disappeared. Even though the algae bloom wasn't here, it seemed the squid had gone," she said. "We'll see a decline in sales through both our stores … it's a fair chunk of our income. But hopefully, the short-term pain will be a long-term gain in the future."
Recreational diver Jeff Bowey, who has explored the waters around Port Augusta for a decade, described what he now finds below the surface. "However the last couple of dives this year; there's been nothing. It's actually a barren desert down there at the moment," he said. "There's something going on in this water that's affected the marine life significantly."
University of Adelaide marine ecologist Ivan Nagelkerken cautioned that the headline numbers hide a slower biological reality. "If we listen to stories of fishermen in terms of how much their catch has dropped as a result of the algal bloom, we could say it's quite significant," he said. Recovery for hard-hit species, he warned, "might take up to years for some species, even decades."
Kyri Toumazos, executive director of Seafood Industry South Australia, put a figure on it: at least a decade to return to pre-bloom normality, with financial damage already in the tens of millions of dollars and more than 100 marine scalefish fishers unable to work. "It's also a way of life for people … so we are now seeing the mental burden that it has on people as well," he said.
Even the state's own bloom spokesman urged caution. Professor Mike Steer, who heads the South Australian Research and Development Institute, said that while results were trending positive, "the job is not done." "This particular Karenia species is responsive to environmental conditions, and it has in the past turned the corner, so we need to be vigilant in terms of our monitoring," he said.
Opposition primary industries spokesperson Nicola Centofanti argued the closures ripple far beyond the boat ramp. "These bans don't just affect those out of the water – they flow right through coastal economies, impacting local jobs, small businesses, and regional communities," she said.
For now, South Australia's anglers face a long winter of locked gates and patient waiting — hoping the squid, the whiting and the snapper come back faster than the science fears.
