Caring for our
Marine Debris Reporting
The Tasmanian Salmon Growers Association (TSGA) has established a hotline and mobile application for reporting marine debris in the State’s waterways. These systems have been established to streamline reporting and to ensure that swift action is taken.
The Tasmanian community has told us that marine debris is not acceptable. We agree. All Tasmanian salmon farmers aim to stop our debris at its source. The hotline and the app will make it easier for the public to report debris so that it can quickly be recovered and we can work to ensure it doesn’t happen again.
By reporting salmon farm debris found on water or on the beach, users of the app or the hotline can – in one streamlined process – notify government authorities and have salmon companies clean it up and identify how to stop it happening again.
The salmon industry aims for zero debris and has enacted policies and processes to guide our work towards that goal. By discussing debris at daily safety meetings, for example, we are making waterway care part of our culture.
The industry conducts regular and frequent (weekly, in some areas) cleanups of nearby shorelines and removes all debris, regardless of origin.
We collaborate with community groups to participate in community marine debris clean-ups - https://www.nrmsouth.org.au/join-our-marine-debris-clean-ups/
Debris Tracker App
The app is available on the iOS and GooglePlay stores - just search for “Debris Tracker”
In a response to members of the public seeking lease coordinates, these are now publicly available via Marine and Safety Tasmania’s (MAST) new list website https://maps.mast.tas.gov.au/index.php
Clearer internal processes are in place which are constantly being reviewed in order to improve company responses to navigational hazards.
Water Quality Monitoring
The Broadscale Environmental Monitoring Program (BEMP) is a regulatory requirement that commenced in 2009, and was reviewed by The Institute of Marine and Antarctic Studies (IMAS) in 2013. Parameters measured include the biota and chemistry of sediments; and nutrients, dissolved oxygen and phytoplankton from a variety of depths in the water column.
The design of the BEMP was based on projects undertaken by the Aquafin CRC, IMAS and CSIRO.
Sampling occurs from North West Bay to Recherche Bay in the south. The program has collected over 75,000 individual data points (see Appendix 1). It is aimed at assessing water quality and sediment health at 15 sites in the region occupied by salmonid farms in the D’Entrecasteaux Channel and Huon Estuary.
This monitoring program not only benefits the salmonid industry, but also serves to assist coastal managers and regulatory bodies to better understand the marine environment in the Channel and Huon regions. It is considered a world’s best practice program in terms of broadscale assessment of the impacts of aquaculture on an ecosystem.
