Tassal, Huon Aquaculture and Petuna are Australia's 3 biggest farmed salmon companies and make most of Australia's salmon. None of them collect their waste - they dump it in our oceans. At least 10.6 million kilograms of salmon poo a year is dumped on Tasmania's marine life and laws allow big salmon companies to kill 100% of marine life on the seafloor under their farms.

This petition will make a difference because it asks supermarkets - the big buyers of salmon in Australia - not to buy dirty stuff and to lift standards in their procurement policies.
