Salmonid aquaculture production in Macquarie Harbour (both Atlantic Salmon, Salmo salar, and rainbow trout, Onchorynchus mykiss) has steadily increased from <1,000 tonnes in the early 2000’s to >20,000 tonnes in 2015/16.

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).

The Macquarie Harbour water column is highly stratified due to the significant freshwater inputs from the Gordon and King Rivers, deep central basin (maximum depth ~ 50m) and shallow sill at its mouth (<5 m) that restricts exchanges with the ocean.

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.

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.

The present study, undertaken by the Institute for Marine and Antarctic Studies, represents the first major investigation of the ecology and biology of the endangered Maugean Skate (Zearaja maugeana).

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.

10/01/2016

The Tasmanian salmonid industry is planning for a significant expansion of salmon aquaculture in Macquarie Harbour. This will result in an increase in nutrients – nitrogen and phosphorous – from salmon farming waste products into the environment.

12/01/2012

The Tasmanian salmonid aquaculture industry is the largest seafood sector in Australia. In the 2010 – 2011 financial year the industry produced 32,328t of salmonids with a farm gate value of $379 million.

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.
