The EPA currently regulates finfish farming at four marine farming leases in the Turrakana / Tasman Peninsula and Norfolk Bay region.
The location of these finfish farms and associated environmental licences can be accessed via the EPA Regulated Premises layer on LISTmap.
The Marine Farming Development Plan for the region is available on the Natural Resources and Environment Tasmania website.

Marine Farming Lease No.55 Long Bay – IMAS Reef Research Final Report
In response to concerns about nuisance algae in Port Arthur, the EPA commissioned the University of Tasmania Institute of Marine and Antarctic Studies (IMAS) to undertake rapid visual assessment surveys and stable isotope analysis on reef ecosystems in Long Bay and across the broader Port Arthur region.
The purpose of these surveys was to:
evaluate the condition of inshore rocky reef ecosystems in Long Bay and the broader Port Arthur region; and
investigate potential nutrient enrichment from the finfish farm located at the southern end of Long Bay.
IMAS submitted an initial report - Rapid visual assessment of rocky reef assemblages in Port Arthur, February 2022 - to the EPA on 26 July 2022 following external scientific peer review. The EPA provided the farm operator, Tassal, an opportunity to comment on any matters of fact in a draft of the report. The report outlines findings from surveys in January and June 2021.
As an evidence-based regulator, the EPA welcomes this IMAS report which significantly advances our understanding of environmental impacts in Port Arthur. The EPA will now consider its response to the report, together with the following information:
- independent EPA monitoring conducted since 2019, including a recently finalised nutrient investigation (see Port Arthur Monitoring Program);
- existing BEMP monitoring data (see above); and
- the Tasman BEMP Annual Report for the monitoring period May 2021 to April 2022, which represents a significant body of environmental monitoring work in Long Bay and the broader Port Arthur region.
Furthermore, the EPA is awaiting the following information:
- a supplementary report from IMAS with results from repeat reef surveys in January and June 2022 is expected in early 2023; and
- additional environmental studies undertaken by Tassal's consultants within Long Bay and the broader Port Arthur region, particularly as relates to the period from 2013 to 2016 when fish farming had ceased in Long Bay.
The EPA's consideration of the above information highlights the importance of the Government's proposed Environmental Standard for Marine Finfish Farming that is being progressed by the Department of Natural Resources and Environment Tasmania. Fish farms are a known source of nutrient inputs to water bodies; hence some level of impact is not unexpected. A public process leading to clear, published environmental standards for assessment of such impacts will assist the EPA in its regulatory role.
