Environmental Assessment of Aquaculture in Western Australia

Barramundi Farm Western AustraliaOne of the barriers to the development of large-scale aquaculture in Western Australia has been the legislative regime for environmental approvals. Due to the lack of any explicit direction detailing information requirements crucial for assessment purposes, applications often experience significant delays in gaining approval to commence operations or to up-scale to more commercial volumes.

The Department of Fisheries (DoF), Department of Environment and Conservation (DEC), industry representatives and licensees recognised that a duplication and overlap in the environmental assessment of aquaculture existed. This prompted a review of environmental legislation by DEC in 2005. Aquaculture activities in general are low risk and regulations are now being amended to totally preclude aquaculture activities from the requirement to be separately environmentally licensed by DEC.

Environmental Management Systems for Aquaculture

Environmental management systems are also starting to evolve for some forms of aquaculture, as well as more formal environmental management systems (EMS). EMS is a complex approach with little direct application to small- and medium-sized farms, however, EMS principles provide useful guidance for improving environmental management of aquaculture production systems.

EMS assemble management policies, programmes and practices designed to identify links between industry, urban and developmental activities, and consequent pressures on the environment. An effective EMS for aquaculture should establish indicators of changes in the environment, including land, water and aquatic resources. Policies and practices responding to the changes are implemented with continuous feedback to reduce/mitigate any environmental impacts. These indicators should make clear links between environmental impacts and aquaculture activities. The indicators should also reflect positive and negative impacts of environmental influences on aquaculture, as well as visa versa.
