Macquarie Harbour is subject to a range of environmental conditions that influence its hydrology, water quality and benthic environment, which makes interpretation of observations in the context of salmon production particularly complex.
- Management DeterminationsThe EPA issues Management Determinations, Environment Protection Notices and orders for management actions to the companies involved in salmon farming. This has included setting the Biomass Limit for the harbour and approving waste capture treatment and disposal.
- MonitoringCompliance monitoring by the salmon companies is a requirement of the marine farming environmental licence. The companies undertake regular benthic visual surveys using a remote underwater video camera, and these survey reports along with the video footage are sent to the EPA.
- ResearchResearch information for Macquarie Harbour is provided from a number of sources, including the salmon companies, private consultants, University of Tasmania, Institute of Marine and Antarctic Studies, Government and the EPA.
- Environmental Monitoring of Macquarie Harbour WHAApproximately one third of Macquarie Harbour is located within the boundary of the Tasmanian Wilderness World Heritage Area (TWWHA). With the expansion of marine farming in the harbour over recent years, there has been an increase in environmental monitoring of potential impacts on the World Heritage Area (WHA).
The Environment Protection Authority acknowledges the Tasmanian Aboriginal people as the traditional custodians of lutruwita (Tasmania) and pays respect to their Elders, past and present.
