Rising ocean temperatures threaten Tasmania's salmon industry

A University of Technology Sydney report warns that warming oceans pose an existential threat to Australia's billion-dollar salmon farming industry.
A University of Technology Sydney report has warned that Australia's billion-dollar salmon farming industry faces an 'existential threat' from global warming. The 41-page Swimming Against the Tide report, commissioned by the Australian Marine Conservation Society, found that just 1C of ocean warming could put $23.7 million in revenue at risk for one of Tasmania's major salmon firm, due to increasing fish deaths.
More than 90 per cent of Australia's farmed Atlantic salmon is produced in Tasmanian waters. Warming seas are already contributing to mass mortality events by reducing oxygen levels and increasing disease outbreaks. Ocean temperatures are currently up to 3C above average around southern Australia, with strong El Niño conditions forecast to persist.
Researchers examined public sustainability reports, financial disclosures and business strategies from Tasmanian firms Tassal, Huon and Petuna. The report found these producers are not adequately quantifying the potential cost of salmon deaths due to climate change or the cost of adapting to it. University of Technology Sydney researcher Hollie Cheung said the industry is 'highly vulnerable to climate change'.
