Hundreds of tonnes of farmed salmon worth millions of dollars have been killed by storm surges on Tasmania’s west coast.
It is believed to be the state’s biggest single fish kill and has raised questions about the industry’s plans for expansion in Macquarie Harbour.

The company has attributed the deaths to a big storm earlier this month which it said was the most severe of its kind in almost a decade.

After the incident, which Petuna described as minor stock loss, the fish were buried at a nearby landfill site.
