Branchial surfaces of finfish species contain a microbial layer rich in commensal bacteria which can provide protection through competitive colonization and production of antimicrobial products. Upon disturbance or compromise, pathogenic microbiota may opportunistically infiltrate this protective barrier and initiate disease.

Amoebic gill disease (AGD) is the primary health concern for Atlantic salmon Salmo salar farmed in Tasmania, Australia. Neoparamoeba perurans is the aetiological agent of AGD; however, a diversity of other amoebae colonise the gills, and their role in AGD is unknown.

There is an urgent need to develop novel treatments which would reduce the impact of AGD on salmon industry. A detailed benefit – cost analysis for the AQUAFIN CRC AGD project was undertaken which gave a Net Present Value of the economic benefit of $21.6M, Benefit/Cost Ratio of 5.3.

01/01/2005

Tasmanian salmon typically mature after only one winter at sea, in contrast to northern- hemisphere populations where the majority take two ‘sea-winters’ to mature. The Tasmanian fish still reach 3 – 5 kg during this period due to the favourable effects of higher temperature on growth, however, the less desirable outcome of early maturation is the compression of the harvest season.

Management costs (ca. 10% GVP) associated with AGD are severely limiting further expansion and sustainability of the Tasmanian Atlantic salmon industry. A holistic approach that combines alternative treatments, better management procedures, the use of a vaccine and selection of stock that are more resistant to infection would greatly reduce the impact of AGD.

08/01/2008

Ambient environmental conditions mean that the Tasmanian salmon industry will always suffer from high maturation rates due to its high water temperatures and increased light intensity. Additional artificial lighting in Tasmania has been shown to reduce maturation by up to 30%; increase growth rates significantly; and delay maturation by 8 weeks (Porter et al., unpublished).

Antibiotics and antifoulants are used in aquaculture operations to ensure the health and well-being of farmed stock. Antibiotics are used as a direct response to infectious diseases, whilst antifoulants are needed to counteract bio-fouling, a condition which is a significant problem to the local aquaculture industry and reduces water flow and oxygen supply in the cages, increasing stress levels and hence diseasesusceptibility in the fish.

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.

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.

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.
