Supporting expansion of fish farms in Tasmania

An integrated decision support system to support an environmentally safe increase of aquaculture production in Macquarie Harbour

The expansion of aquaculture in Macquarie Harbour is set to anticipate and meet the growing regional and global demand for marine salmon and trout products. We were called in by one of the local growers to conduct a diligent study for this expansion and lead discussions with the involved stakeholders — the three growers (currently situated in the harbour) and the local authorities.

Our thorough study enabled us to identify a scenario meeting both the needs for increased fish production and environment preservation. It resulted in the approval of a 64% increase in leasable water space expansion, expected to lead to a local production growth from 6,000 tonnes up to 30,000 tonnes — equivalent to AUD 379 million yearly farm gate value.
