Is eating prawns good for you?
Yes, it certainly is. Did you know that Australian farmed prawns are a good source of Protein, Omega 3, Copper and a source of Selenium?
Just 100 grams of farmed black tiger prawns contain as much omega 3 as 1000 grams of chicken breast.

Prawn Farming in Australia
Aquaculture prawn farming began in the 1980’s with most farms being located on flat land adjacent to sea water sources, such as tidal rivers or creeks.
Prawn farms require temperatures above 25º C during productions season; therefore currently 95% of farms are located in Queensland and 5% in NSW.
Total land currently used for production is in excess of 900 hectares and clusters of farms can be found on the Logan River, Mackay, Bundaberg, Townsville, Cairns and Yamba NSW. Some of the biggest farms produces prawns all year round whilst the other farms produce one crop per annum and harvesting is usually completed by the end of April each year.
It takes approximately 6 months for prawns to grow to harvesting size and most of the prawns are sold domestically in Australia. Processing is carried out as soon as harvested with most farms having their own production facilities that include grading, cooking, packaging and freezing.
Prawn farming is Queensland’s largest aquaculture sector providing hundreds of FTEs employment mostly in rural communities.
What does it mean being a Prawn Farmer?
Being a farmer is high risk, capital-intensive, site specific and requires technical expertise. You must be prepared to work long hours and must be able to understand and manage sudden changes in conditions that can occur at any hour of the day or night. Managers must have a firm hand on risk management, marketing and liaison with various government bodies.

Farmed Prawn Species
Prawn Species farmed are currently the black tiger prawn Penaeus monodon and the banana prawn Fenneropenaeus merguiensis.
The kurama prawn Penaeus japonicas has been farmed in the past.
1. Water Quality in Australia
70% of current Australian farmed prawn production occurs adjacent to the World Heritage-listed Great Barrier Reef Marine Park. The prawn farming industry in the Great Barrier Reef Region is a highly profitable, but small agriculture sector, which has potential to expand considerably without impacting on coastal water quality.
It is well known that the Great Barrier Reef is a World Heritage Protected icon.
APFA acknowledges that the Great Barrier Reef World Heritage Area is affected by material originating from a range of human activities, both on the land and in the water, such as agriculture, urban and industrial development. The 2014 Great Barrier Reef Strategic Assessment and Program Outlook Report states that the reef is an icon under pressure from elevated concentrations of suspended sediments, excess nutrient and pesticides.
Whilst prawn farming is a very small contributor to these loads (just 0.16% of Nitrogen, .08% of Phosphorus, 0.000006% of solids and no pesticides) we recognise that it is incumbent on all to contribute to preserving this precious resource.

2. Water Treatment
Waters released from a prawn pond may contain nutrients, algae and clay particles which occur naturally in ocean waters.
Most Australian prawn farms allocate up to 30% of their productive land for settlement systems. These systems reduce suspended solids (particulate matter, organic material, sediment) and dissolved nutrients in the effluent before released back into an estuary.
A seven year multidisciplinary study on the environmental management of prawn farming was conducted (1995-2002). The study integrated the research skills of 30 scientists from several institutions including:
- Australian Institute of Marine Science,
- University of Queensland,
- Queensland Department of Environment Protection Authority,
- Griffith University,
- University of Sydney,
- University of Technology,
- Marine and Freshwater Resources Institute, Victoria and the
- University of Maryland USA.
Studies focused on the largest prawn farms in Queensland and New South Wales throughout their production cycle and encompassed a range of latitudes, discharge environments (eg tidal creeks and estuaries) and both flow through and recirculating water management systems and produced 42 peer reviewed research papers.
Key elements of the studies were:
- prawn pond sediment and nutrient processes,
- composition of prawn pond discharges,
- discharge treatment systems and environmental management,
- receiving waters – assimilation and monitoring,
- synthesis of pond processes and environmental management and
- aquaculture land use planning.
Key outputs of these studies were:
- prawn pond sediment and nutrient processes rigorously quantified and modelled,
- pond discharge composition rigorously quantified,
- published the first synthesis of the dominant ecological processes in ponds and adjacent coastal environments,
- in collaboration with industry – designed and implemented cost-effective treatment system based on sedimentation processes.
Many Australian farms recirculate water as routine practice. Partial recirculation helps minimise fluctuations in water quality (salinity, turbidity, nutrient load) and reduces the risk of introducing pathogens from the wild. However partial recirculation is not suited to all farms. Farms have variable requirements depending on a range of factors including quality of intake water, location in the catchment, availability of land, rainfall and access to tidal waters.

Protecting Marine Plants
Under state laws, marine plants are totally protected.
This includes all species of mangrove, seagrass and seaweed. If any plants are approved to be removed, they can only be removed after investigation by authorities who generally only allow removal conditional on appropriate mitigation. In the process of making that decision, authorities are required by law to consult with all interested members of the community – this includes conservation groups, scientists, recreational and commercial fishing interests.
It should be noted that large scale mangrove destruction does not occur on Australian prawn farms.
Australian prawn farmers produce native species. Exotic pests are the most critical disease threat to Australia’s prawn producers.
APFA do not want to stop prawn imports. However, Australia’s prawn farming industry does not support the importation of uncooked prawn for human consumption or bait from countries which cannot demonstrate freedom from OIE-listed diseases and calls for all uncooked prawns to be cooked before crossing Australia’s border – thereby still allowing trade while protecting Australia’s iconic “Aussie prawns”, Australian seafood and our beautiful waterways.
Read our submission to the Australian Government Department of Agriculture, Water and the Environments on why we support cooking prawns before crossing Australia’s border.

Inside Prawn Ponds
What’s going on inside prawn ponds?
With the support of Australian prawn farmers, scientists have studied the environment of prawn ponds and the effects of pond water discharges. The knowledge is helping farmers to improve pond management and is guiding the sustainable growth of prawn-farming in Australia.
Learn what’s going on inside prawn ponds starting with early growth stage, advanced growth stage, lining ponds, settling time followed by wastewater reuse and active treatment up to “going downstream” from farm discharge.
