Marine Farm Planning Proposals

​​Current Planning Proposals​

Draft amendment no. 3 to the Storm Bay off Trumpeter Bay North Bruny Island Marine Farming Development Plan

Draft amendment no. 5 to the Tasman Peninsula and Norfolk Bay Marine Farming Development Plan

Draft Storm Bay North Marine Farming Development Plan

All three proposals relate to areas of Storm Bay.

Overview of Proposed Storm Bay Developments

Storm Bay is identified in the Government's Sustainable Industry Growth Plan for the Salmonid Industry​ as a priority area for the possible expansion of salmonid marine farming. 

Opportu​nities in this area are being explored by each of Tasmania's three major salmonid producers: Tassal Operations Pty Ltd, Huon Aquaculture Company Pty Ltd and Petuna Pty Ltd (Figure 1).

Each company is progressing planning processes under the Marine Farming Planning Act 1995 to increase the capacity of finfish marine farms in Storm Bay. The companies have aspirations for a total production from Storm Bay of 80,000 tonnes per annum. In recognition that robust scientific information is not currently available to predict the environmental effects of this level of production, the potential environmental effects of a combined level of production of approximately 40,000 tonnes per annum are being considered in the environmental impact statements that support these planning processes. This is similar to the level of production achieved from the Huon River and Port Esperance, and D'Entrecasteaux Channel marine farming development plan areas combined. It represents an increase of approximately 24,000 tonnes in potential annual production from Storm Bay.

The Government's intention is that the proposed developments would be managed under an adaptive management framework (figure 2), underpinned by:

  • A staged development approach, with an initial limit on feed input[1] that would provide for approximately 30,000 tonnes of production
  • A comprehensive environmental monitoring program
  • The development of a biogeochemical model, to help to understand the information provided by the environmental monitoring and the effects of any changes to farming operations in the region.

The Environment Protection Authority has indicated that, should the proposed developments proceed, feed inputs will initially be limited to provide for approximately 30,000 tonnes of production annually. This staged approach towards 40,000 tonnes of annual production would provide the opportunity for assessment of environmental responses.

An increase in production within the proposed areas beyond 40,000 tonnes would be subject to a separate assessment process. This would be informed by the proposed environmental monitoring program, which will collect data on environmental performance indicators to provide an understanding of interactions between salmonid farming and the receiving environment. This information will provide a robust framework to detect localised, intermediate and ecosystem level changes, enabling appropriate regulatory responses.

In addition, the monitoring program will provide for the development and validation of a biogeochemical model for Storm Bay. The model will estimate natural assimilation of salmonid derived nutrients at varying spatial and temporal scales relative to specific biomass output. This will inform adaptive management by forecasting the potential environmental impacts of salmonid farming in Storm Bay. The model will be developed in collaboration with CSIRO and the University of Tasmania's Institute for Marine and Antarctic Studies (IMAS). Development of the model is expected to commence in conjunction with monitoring.
