The EPA currently regulates finfish farming at one marine farming lease in the Kanamaluka / Tamar Estuary region.
The location of this finfish farm and associated environmental licence can be accessed via the
EPA Regulated Premises layer on LISTmap. See our Site Information page for details.
The Marine Farming Development Plan for the region is available on the
Department of Natural Resources and Environment Tasmania website.
MF178 Long Reach (Rowella)
Total Permissible Dissolved Nitrogen Output
From 1 July 2023 the scale of finfish farming in Kanamaluka/Tamar Estuary has been regulated via a condition in the Environmental Licence that sets a Total Permissible Dissolved Nitrogen Output (TPDNO).
Van Diemen Aquaculture (Petuna) must comply with the TPDNO. Dissolved nitrogen emissions are calculated from feed inputs and are measured in tonnes of nitrogen emitted per rolling 12-month period.
To date environmental monitoring around the Rowella lease (MF178) has not demonstrated ongoing impacts or effects of concern. As such, the TPDNO has been set based on forecast finfish production to 2024. Any expansion of finfish farming beyond the TPDNO set in the Environmental Licence would require an application and assessment by the EPA.
