Dead fish washed up onshore at Seaspray in Gippsland
Many beachgoers had reported the dead fish between Seaspray and Marlo in Gippsland, identifying mainly the leather jacket species and also trevally.
The EPA said it was investigating but test results did not indicate water pollution was the cause.
It said the fish were most likely killed by cold Antarctic waters moving up the east coast.
The fish prefer warmer waters.
Large numbers of dead fish have also washed up on Tasmania's east coast.
Beachgoers reported the dead fish found along Ninety Mile Beach.
Is the AntArctic Circulation breaking down, and nobody noticed (or said anything) ?
