    Benthic Monitoring

    Environmental licences require companies to undertake regular visual monitoring of the seabed to detect 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 vehicles fitted with high definition cameras. Visual monitoring occurs at compliance points located around the lease area. Where significant impacts are detected, additional monitoring surveys are conducted at points further away to assess impact.

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

    Data is required to be collected annually, however the timing of environmental surveys is lease dependant and can take place within any month throughout the year.​

  • Fish Health

    ​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*. This information 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 Investments 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*. This information will be reported on this site in the quarter after it has been reported to market in the case of publically listed companies.

    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

    ​​​​​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.  

    Operations specific to the Marine Farming Inspection Program during Q1 and Q2 2020 were ​impacted by restrictions put in place as a result of the COVID-19 Pandemic.​

    Infringements

    When an infringement is detected, authorised officers from Government or Marine and Safety Tasmania may issue an infringement notice.

    ​​​​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.  

    In undertaking these activities it is important to ensure that any sensitive bird breeding habitat is not impacted and that removal of debris does not occur during shorebird breeding seasons. BirdLife Tasmania has provided guidance on where and when shorebirds may be most vulnerable and general operational limits are now in place from October 1st – March 31st with some shoreline areas classified as 'do not proceed' and others as 'proceed with caution under advice'. As such, corresponding 'effort' through these periods may appear reduced in some marine farming areas.

    Operations and activities specific to the Marine Debris Clean ups program during Q1 and Q2 2020 were impacted by restrictions put in place as a result of the COVID-19 Pandemic.

    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.

    ​​​​​​​HOG Weight

    HOG Weight refers to the weight of a fish “Head On Gutted” and is how companies and the market refer to the weight of fish in a commercial setting.

    Companies that are listed on the Australian Stock Exchange are required to report this information to their shareholders.  HOG data will be reported on this site 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 Investments Commission.​​
