Scientists say the latest report on salmon farming in southern Tasmania shows the industry is healthy and sustainable.
Researchers at the Institute for Marine and Antarctic Studies have been monitoring the release of nutrients by fish farms in the D'Entrecasteaux Channel and Huon estuary between 2009 and 2012.
The study also reviewed the effectiveness of the Government's monitoring program.
Professor Colin Buxton says the report gives the salmon industry a clean bill of health, despite some nutrient release.
"It's very clearly demonstrated that there are no adverse consequences for the environment," he said.
"So the nutrient load that's coming into the system through salmon farming is at an acceptable level and certainly below the cap that the government set for them."
