Macquarie Harbour Marine Farming Development Plan

​​​Environmental Data​

Environmental data is collected by the EPA, industry, the Institute for Marine and Antarctic Studies (IMAS), and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) through separate monitoring programs.


Maximum Permissible Biomass 

The Director, EPA, determines the quantity of fish permitted in an Area. This quantity is referred to as a biomass limit. The Director’s decisions take account of potential environmental, social and economic impacts in the Area. 

The maximum permissible biomass within Macquarie Harbour for the period commencing 1 June 2018 until 31 May 2020 is 9,592 tonnes, allocated on the basis of lease area held by the companies.

Historical data:

The biomass limit apportioned between Tassal Group Pty Ltd, Huon Aquaculture Group and Petuna Aquaculture Pty Ltd in the first period was set on the basis of the actual biomass of salmon as it existed in the harbour at the November 2016.

Benthic Monitoring

Environmental licences require companies to undertake regular visual monitoring of the sea bed to record environmental changes associated with farming salmon. This occurs at all salmon farming sites across Tasmania.

 
One requirement is that there must be no significant visual impacts at, or past, 35 metres from the lease area. Visual impacts are monitored by remotely operated dive vehicles with cameras at compliance points located around lease area. Where impacts are detected at these points, additional dives are conducted at points further away.

 
If a significant impact is detected within or outside the lease areas, the EPA may require specific responses as well as further investigation.

Fish Health Data

Significant mortality event reported

A company has to immediately notify the Government of any significant illness, mortality or disease in their fish.

 
Companies that are listed on the Australian Stock Exchange are required to report this information to their shareholders at set dates each year. These incidents will be reported on this site in the quarter after they have been reported to market in the case of publically listed companies. This is necessary to avoid breaching the rules for companies that are set by the Australian Securities and Investment Commission.​

Mortality within a cage >0.25% for three consecutive days

A company must report as soon as possible any suspected or known incidents of disease or mortality affecting greater than 0.25 per cent of fish per day for three consecutive days in any individual cage. 

 
Where fish mortalities are not collected daily then the morts need to be averaged over the number of days between collection. For example if there are 1.2% morts collected today but it has been 4 days since the morts were collected then it has been 0.3%/day for 4 days  (which is reportable)  not one day at 1% (which is not reportable).

 
Companies that are listed on the Australian Stock Exchange are required to report this information to their shareholders at set dates each year. These incidents will be reported on this site in the quarter after they have been reported to market in the case of publically listed companies. This is necessary to avoid breaching the rules for companies that are set by the Australian Securities and Investment Commission.

Seal mortalities

​A seal death that is attributable to salmon farming is defined as: 
A mortality caused by an interaction with marine farming activities, operations and infrastructure including but not limited to: entanglement, vessel strike, other infrastructure interaction, deterrent use, sedation, and humane destruction.

 
Whether or not a seal death was caused by salmon farming activities is determined on a case by case basis after assessing all of the facts.

Operational Compliance Data

Marine Farm Inspections

There are a range of requirements that licence and lease holders must comply with. These are created by instruments such as legislation, licences, leases and Marine Farming Development Plans. The Government has an inspection program where authorised officers from Government or Marine and Safety Tasmania visit and inspect marine farms for compliance.

Marine Debris clean ups

As the population and industries expand, marine debris is a growing environmental and navigational issue for the waterway. 
Debris may come from lots of sources including:
  • pleasure craft
  • commercial vessels
  • fish farming activities
Debris may also end up in the ocean from land, for example litter, and runoff from stormwater drains. Finfish and shellfish farmers monitor and remove marine debris from nominated shorelines through an ‘Adopt a Shoreline’ initiative. The Government also participates in shoreline clean up activities. This helps to ensure that any debris, whether marine farming related or not, is collected and Tasmania’s coastline is protected.

Marine Farming Equipment Register

The Government has developed an equipment identification register with the three salmon companies to enable ownership of debris to be established. Companies have assisted in this regard with gear marking and colour coding of equipment for identification purposes. The register is a statewide register of equipment.

Fish escapes notified to DPIPWE

Salmon farmers must not release into Tasmania’s waters any fish unless authorised to do so. If fish are released this is a breach of their licence and operators must notify Government. 

The table below shows which companies have reported fish escapes to Government.  Sometimes companies fail to report fish escapes, and this is a breach of their licence and they may be penalised.

 
Companies that are listed on the Australian Stock Exchange are required to report this information to their shareholders at set dates each year. This data will be reported on this site in the quarter after it has been reported to market in the case of publically listed companies. This is necessary to avoid breaching the rules for companies that are set by the Australian Securities and Investment Commission.
