More than 30 years later, the proudly family-owned business now sends approximately 120 tonnes of fresh barramundi around Australia and to international markets each week. 

The Richards family, who pioneered sustainable aquaculture in Australia, are celebrating another major milestone in their journey – becoming the first Australian barramundi farm to achieve Aquaculture Stewardship Council certification. 

Widely regarded as the global gold standard for responsible aquaculture, the certification is a milestone for the Australian seafood industry. 

The achievement is a result of decades of investment in infrastructure, people and the land itself. 

The 700-hectare property, which is on the banks of the Adelaide River, has been carefully developed, with less than half the property dedicated to ponds and water treatment systems. The remaining area is preserved as wildlife corridors or retained for future development.

From the beginning, the aim has been to prove that large-scale food production and genuine environmental stewardship can go hand-in-hand. 

“We’re always striving to improve, to be more responsible, more sustainable, and to farm with nature, not against it,” says chief executive Dan Richards. 

That philosophy can be seen across every aspect of the operation. The farm’s award-winning saltwater wetland recirculation system naturally filters water through native grasses and cleans it for re-use. The closed-loop solution protects surrounding waterways, ensuring that more than 99 percent of nutrients are retained on the farm and helping maintain optimum water quality to keep fish healthy and happy. 

The sustainability focus is also being rolled out in other parts of the farm. Humpty Doo Barramundi has invested heavily in packaging innovation, replacing Styrofoam packaging with URTHCOOL insulated boxes made from 100 percent recyclable Australian materials, and recyclable pallet wrap. 

“Our responsibility doesn’t stop at the farm,” says co-owner Tarun Richards. “Implementing sustainable solutions throughout our supply chain demonstrates to customers and suppliers that we are serious about the impact we are having.” 

Fish welfare is another major focus. Water quality is continuously monitored across the farm, while low stocking densities and a carefully managed nursery system support fish health from an early stage of development. An additional nursery completed in 2020 provides next-level care, allowing juvenile fish to spend more time in a controlled indoor environment before transfer to outdoor ponds. 

Aquaculture Stewardship Council certification places independent verification behind these practices. To achieve certification, farms undergo a rigorous third-party audit spanning environmental management, fish welfare, labour rights, community engagement, feed traceability and stakeholder transparency, ensuring sustainability claims are backed by evidence, not just intention.

For retailers and food service operators around the world, the ASC mark is increasingly becoming a prerequisite for supply, and Humpty Doo Barramundi now meets that benchmark. 

“Our customers and community want independent proof that we do what we say we do,” says Tarun. “This certification provides exactly that, and it reflects the dedication of our team that genuinely cares about producing beautiful-tasting barramundi in the best possible way.” 

The farm’s relationship with the broader community is equally long-term in its thinking. Through its support of the Palmerston Game Fishing Club’s annual Junior Angler Education Clinic, Humpty Doo Barramundi is helping young people gain practical fishing skills like safe fish handling and release, emergency response, and boating and crocodile safety. These skills are teaching the next generation how to fish responsibly and safely in the future. 

The company has also established a two-way learning partnership with the Aboriginal community of Wadeye, through Thamarrurr Development Corporation, supporting the development of a small-scale aquaculture enterprise through knowledge sharing, training, and practical experience. 

It is this company-wide commitment that also earned Humpty Doo Barramundi ASC’s Best Responsible Seafood Producer at the 2026 Sustainable Seafood Awards Australia, selected from producers across the country. 

“We focus on continuous improvement not just on the farm, but across our entire value chain,” says Tarun. “This recognition means a great deal to our team, but for us it’s also just the beginning.” TQ
