This study, undertaken by the Institute for Marine and Antarctic Studies (IMAS) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) was commenced to investigate deteriorating benthic conditions in Macquarie Harbour; in particular the very low dissolved oxygen (DO) levels observed in the middle and bottom waters in spring 2016 (Ross & Macleod 2016a).

This study was commissioned by the Department of Primary Industries (DPIPWE), Tasmanian Abalone Council (TAC) and representatives of the Tasmanian salmonid farming industry (Tassal Pty. Ltd and Huon Aquaculture Pty. Ltd) to establish whether salmon farming has a major contribution to sedimentation on reef ecosystems in farming regions and to determine what analyses and methods might be most appropriate for detecting fish farm signatures.

The combined biomarker approach (C:N, isotopes, fatty acids and genomics) provided valuable insight into the source, composition and transformation of organic matter in the harbour

The expansion of salmon farming in Macquarie Harbour is contingent upon ecologically sustainable development. Underpinning such development are management regimes designed to regulate and minimise the impact of farming on the benthic environment.

This report provides an update on the status of dissolved oxygen and benthic conditions in Macquarie Harbour. It follows on from the results reported in the IMAS report released in January 2017 which described the deterioration of benthic and water column conditions in Macquarie Harbour in spring 2016.

05/01/2017

To understand dispersal and assimilation of aquaculture waste subsidies in a naturally low-productivity environment, we applied a novel, rapid transmethylation technique to analyse sediment and biota fatty acid composition.

This report provides an update on the status of dissolved oxygen and benthic conditions in Macquarie Harbour. It follows on from the results reported in the IMAS reports released in January and May 2017 which described the deterioration of benthic and water column conditions in Macquarie Harbour in spring 2016 and subsequent observations in early 2017, respectively.

This study was undertaken at the instigation and with the collaboration of the Tasmanian Salmon Aquaculture industry, the Department of Primary Industry, Water and Environment (DPIWE) and the Fisheries Research and Development Corporation (FRDC).

08/01/2004

This study was undertaken to fill a significant gap in our understanding of the system ecology of the two main estuaries in southern Tasmania and to provide baseline information to assist in the ongoing management of these systems.

The salmonid aquaculture industry depends on a healthy and suitable marine environment to maintain production and profitability. Over recent years, the industry has faced a number of environmental challenges, including algal blooms, jellyfish swarms, warm waters and high salinities.

This study was undertaken to assess the Gunpowder Jetty site(Marine Farm lease No.76) 10 years after it was finally vacated to determine whether the benthic, visual and physicalchemical conditions were consistent with background conditions and to what extent the system has recovered.

The Broadscale Environmental Monitoring Program (BEMP) provides a comprehensive assessment of ecological condition in the D’Entrecasteaux Channel and Huon Estuary.

Farm based monitoring has shown copper concentrations in sediments under salmon farms in the Huon and D’Entrecasteaux Channel are elevated relative to background conditions as a result of long-term use of copper-based antifoulants.

The strategic growth of the Tasmanian Salmonid Industry over the next decade is contingent upon ecologically sustainable development in Macquarie Harbour. In coastal bays and estuaries, it is well known that sediment - water column interactions are a major driver of ecosystem condition and health.
