New satellite images from NASA have confirmed that the mass fish kills across South Australian waters last month was likely caused by a naturally occurring algal bloom.

The South Australiaan Government formed a special team of scientists who looked to confirm their original theory based on satellite images from the CSIRO.

State Minister for Fishers, Gail Gago, said that the scientists confirmed that the worst of the bloom is likely over.

“We now have a second independent set of satellite images that confirm the presence of high algal abundance in the water and elevated water temperatures around early March when dead fish washed up at Port Neill on the Eyre Peninsula,” she said.

Ms Gagp said that recent diagnostic testing had ruled out infectious diseases as the cause of the mass fish death.

“Further to this, pathology results have indicated gill irritation which is consistent with unusually high water temperatures and possible harmful algae,” Ms Gago said.

The Health Department has advised that algal blooms that cause fish deaths through oxygen depletion and gill damage do not affect human health through recreational use of water.
