You may want to read the first paragraph of the Govt sponsored Cawthorne report that was done to assess the biomass cap. After receiving this report the Govt put up the cap which is unbelievable.

An expansion of salmonid farming in Macquarie Harbour was approved in 2012, potentially enabling production to increase to 29,000 tonnes per year. Since 2012, there has been a steady production increase to the present level of ca. 20,000 tonnes per year, which has been accompanied by monitoring of benthic (seabed) health indicators, water quality parameters, and fish health status. Recent monitoring results have revealed changes in key indicators that appear to be inconsistent with anticipated environmental effects. For example, seabed video surveys show changes in benthic indicators that are symptomatic of increased organic enrichment, and water quality monitoring indicates a harbour-wide decline in dissolved oxygen (DO). There are related concerns that fish health status in Macquarie Harbour is indicating a biological system under stress.
