Aquaculture is a sustainable growth opportunity. The OECD and FAO forecast fish consumption to continue rising steadily through 2025. Fish is an increasingly important source of animal protein, having grown rapidly to around 16% of all global animal protein consumption.

The wild fish catch is effectively capped, leaving growth in sustainable aquaculture as the only way to meet rising global demand. Farmed finfish convert feed into body mass 7x more efficiently than cattle and sheep, while producing less than 1/10 the Co2 per kg of cattle and sheep.

Clean Seas’ Spencer Gulf Kingfish sells at a premium to wild caught Kingfish thanks to its superior culinary qualities.

Pristine Environment

Fed by the currents from the Southern Ocean, the Spencer Gulf has some of the purest water in the world. It’s the perfect place to raise our Kingfish and we’re proud to call it home. Unique in Australia, the Spencer Gulf has no rivers feeding into it and no farmland surrounding it. This means there’s no risk of pollution or chemical run-off, so our fish are able to be raised in pristine, peaceful surroundings until they are ready for harvest.





Aquaculture stewardship council certification

The Aquaculture Stewardship Council (ASC) is the world’s leading certification scheme for farmed seafood – known as aquaculture – and the ASC label only appears on food from farms that have been independently assessed and certified as being environmentally and socially responsible. ASC certification code: ASC-C-02593.

Stakeholders – Please note that under the new Farm Certification Requirements for Unit of Certification (RUoC), Clean Seas are required to publish the dates of the upcoming ASC audit (14 to 16 May 2024) with the bio.inspecta contact information ( or in a visible place for local communities and neighbours in case they want to submit any comments.

We proudly adhere to strict Aquaculture Stewardship Council regulations

ASC standards are strict requirements for responsible seafood farming that encourage producers to farm with care for fish, the environment and the people on and around the farm. Certified farms must actively minimise their impact on the surrounding natural environment. They must also operate in a socially responsible manner, care for their employees and work with the local community.

Clean Seas manages its farming operations using global best practice methods to grow world-class, high-quality Yellowtail Kingfish. We’re dedicated to maintaining a pristine marine environment.

research &

Clean Seas boasts one of the best aquaculture research facilities in the world. Our hatchery in Arno Bay, South Australia supports a rigorous research and development program, conducted by our in-house team of qualified researchers in partnership with industry-leading research bodies.

Cleans Seas has ongoing collaborations with: Flinders University, University of South Australia, NSW Department of Primary Industries, South Australian Research and Development Institute, Fisheries Research and Development Corporation, Australian Seafood Cooperative Research Centre, University of the Sunshine Coast, University of Western Australia, CH4 Global, Western Australian Department of Primary and Primary Industries and Regions South Australia.

Cleanseas are collaborating with CH4 Global to investigate the possibilities of positioning seaweed farms downstream from our Yellowtail Kingfish pens so that it can be harvested for use in cattle feed. Being so nutrient-rich, this seaweed is highly effective in reducing methane produced by cattle which in turn helps to reduce greenhouse gases.

Fish health & management

Fish health and welfare is at the forefront of our operation. We have a dedicated team of veterinary and fish health technicians to ensure our fish remain healthy and our fish health management plan is continuously upgraded to reflect the most recent research and husbandry practices.

We believe in fish health optimisation and disease prevention through simple but effective processes. Clean nets, scientifically formulated feeds, optimum stocking densities and a comprehensive fallowing plan are all examples of key elements of the Clean Seas fish health care program. Where new issues arise, the company has a strong history of investment in research to generate knowledge to solve the problems. The fish health team maintains active surveillance programs on all fish stock and employs preventative management practices to identify and manage any problems early.
