Yumbah Aquaculture is a privately held Australian aquaculture company headquartered in Adelaide, operating 18 production sites across South Australia, Tasmania, Victoria, New South Wales, and Queensland. The company is Australia's largest producer of abalone, mussels, and oyster spat, and following its July 2025 AUD 29.3 million acquisition of Clean Seas Seafood it also produces yellowtail kingfish, making it a diversified four-species aquaculture platform.

The business operates a vertically integrated model spanning broodstock breeding, hatchery, grow-out, processing, and distribution. Hatchery technology combines recirculating aquaculture systems (RAS) and flow-through systems, with a capacity upgrade underway at Arno Bay. Processing capability includes proprietary Suspended Animation Freezing for abalone and in-house Yumbah Aquafeeds pelletised feed manufacturing. The company holds ASC certification across abalone farms and is the first Australian oyster producer to achieve BAP certification.

Yumbah generates revenue through wholesale, retail, and foodservice channels domestically across all Australian states and territories, plus international export to North America, Asia, Europe, the UK, and the Middle East. Distribution is executed via dedicated national and international sales teams, regional state-based representatives, and a national retail business manager supporting major retail chains. The B2B oyster spat segment provides a base-load revenue stream from commercial oyster growers in NSW, Tasmania, and South Australia. The customer mix spans enterprise food service accounts, restaurant groups, wholesalers, major retail chains, and sushi/MSO outlets.

• Clean Seas Seafood LimitedcoreStrategic or Co-development Partner · 24 July 2025Yumbah Aquaculture completed acquisition of Clean Seas Seafood Limited on July 24, 2025, for AUD 29.3 million. The deal required shareholder approval, regulatory clearances, and court approval. Clean Seas was delisted from ASX and Euronext Growth Oslo following the merger. This significant acquisition diversifies Yumbah from shellfish into finfish (yellowtail kingfish) farming. Clean Seas operates the Spencer Gulf Kingfish brand and includes hatchery at Arno Bay, multiple farm sites on Spencer Gulf, and seafood processing facility in Adelaide.
