This week the country's second-largest salmon farmer, Huon Aquaculture, took the extraordinary step of launching legal action over its environmental concerns about overstocking against the State and Federal Governments.
It has been dismissed by some as competitive tension between companies, but one of the original salmon farmers from Macquarie Harbour, Ron Morrison, said he had been raising the same concerns for four years.
A scientific report into the health of the harbour has highlighted low dissolved oxygen levels and dead zones under leases.
The Environment Protection Authority (EPA) reduced the amount of fish allowed to be farmed in Macquarie Harbour from 21,500 tonnes to 14,000 tonnes in January.
However, it is believed the current stocking in the harbour is already at around 14,000 tonnes and Huon is arguing it should be dropped to 10,000 tonnes.
